Liver

The liver has no single number. This panel reads the enzymes that leak when liver cells are stressed, the proteins the liver makes, the bile pigment it clears, and the two things most often found driving them: insulin resistance and iron or copper that is not being handled. It covers 9 markers. This page explains what each one measures, what it does NOT measure, and which nutrients are known to move it.

The Library is open to read. Your own numbers after you join.

What this is, and is not

A raised ALT, GGT or ferritin is a measurement, not a diagnosis. ALT and AST sit inside the cell and leak when cells are stressed; GGT rises with alcohol, bile flow and oxidative load; ferritin rises with inflammation whether or not iron is high. The page shows what each number can and cannot tell you. Nothing here names a treatment, and no supplement is offered here as a liver fix.

The reading order

The enzymes first. ALT is the liver-specific one; AST also comes from muscle and heart, so the pair is read together. GGT is the one a standard visit reads least and the one that moves earliest with alcohol: in a cohort comparing active drinkers with abstinent people, GGT outperformed AST and ALT for detecting active use, with a cutoff of 81 U/L carrying 83.7 percent sensitivity and 98.9 percent specificityHH-114095. In a population screening, elevated GGT tracked with alcohol, abdominal obesity and metabolic syndrome togetherHH-142246, and in cirrhosis of different causes its activity correlated with the glutathione system in a direction that depended on the causeHH-140370.

Then what the liver makes and clears. Albumin is the liver's protein output and a nutrition signal; bilirubin is the pigment from red-cell breakdown that the liver conjugates, and it is also an antioxidant: bilirubin protects lipids from oxidation while glutathione protects water-soluble proteins, two complementary systemsHH-367222. In Gilbert's syndrome, oral zinc sulfate lowered unconjugated bilirubin by interrupting its recycling through the gutHH-143534, a reminder that this number is traffic, not damage.

Then the driver most often underneath a fatty liver. In South Asian patients with non-alcoholic fatty liver disease, HOMA-IR, glucose, triglycerides and CRP were all higher than in healthy controlsHH-369838; fasting insulin and triglycerides are read on this panel because the liver's fat is downstream of insulin. Lower plasma glutathione, choline and betaine were associated with fatty liver in postmenopausal womenHH-104870, and in 2,413 adults higher plasma betaine was inversely associated with CT-defined fatty liver while plasma choline itself showed no association after adjustmentHH-258963.

Then iron and copper, the half a liver panel usually skips. Higher serum ferritin was associated with greater risk of metabolic syndrome and fatty liver in a dose-response meta-analysisHH-371055, and the trap inside that number is documented: a woman whose ferritin stayed very high for 19 months had normal transferrin saturation and normal MRI liver iron, so the ferritin was inflammation, not overloadHH-102263. Saturation is the marker that separates the two. Ceruloplasmin is the copper enzyme that lets iron be moved and storedHH-0194; mice lacking it grew liver iron deposits, fatty liver and tissue inflammation that ceruloplasmin replacement limitedHH-293475.

Every chip is a row of the library, approved, with the paper's own title on hover; a count is attention in this library, never a verdict.

The markers, and what they actually tell you

Each marker below carries its technical name, what it measures in plain language, the limits of what it can tell you, and the nutrients known to move it. Where a framework and mainstream practice disagree, both views are shown rather than one being hidden.

ALT & AST (Liver Enzymes)

Levels of two enzymes released into blood when liver cells are stressed, reflecting liver cell integrity (ALT is more liver-specific, AST also comes from muscle and heart).

Typical range: Standard: roughly 7-56 U/L (ALT), 10-40 U/L (AST), lab-dependent. Functional-optimal (opinion): under 25-30 U/L sometimes cited as ideal, based on population studies linking even "normal-high" ALT to fatty liver risk.

Nutrients that move it

  • Milk thistle (silymarin) -- A systematic review of 17 trials found silymarin lowered ALT by about 14 U/L and AST by about 9 U/L in NAFLD patients on average, though individual trial results are inconsistent.
  • Choline -- Required to export fat from the liver as VLDL; deficiency causes fatty liver. RCTs of choline/phosphatidylcholine supplementation in NAFLD show improvement in liver enzymes and steatosis in some trials but not others.
  • Vitamin E -- Shown in the PIVENS trial to improve liver histology in non-diabetic adults with NASH, though this is a specific population, not general "elevated ALT."

Food first: Weight loss (even 5-10% body weight) is the single most evidence-backed intervention for fatty-liver-related enzyme elevation; reduce added sugar/fructose and alcohol; adequate protein and choline (eggs, liver, soy) for fat export from the liver.

When to see someone: Persistently raised ALT/AST deserve a workup rather than an assumption. Viral hepatitis, medication effects and alcohol produce a similar picture to fatty liver and are managed very differently.

Read the studies on ALT & AST (Liver Enzymes)

Gamma-Glutamyl Transferase (GGT)

A liver enzyme especially sensitive to alcohol intake, bile duct issues, and oxidative stress -- often the earliest liver marker to rise with heavy alcohol use.

Typical range: Standard: roughly 8-61 U/L (men), 5-36 U/L (women), lab-dependent.

Nutrients that move it

  • Vitamin C -- GGT is part of the body's glutathione recycling system, so chronically elevated GGT partly reflects oxidative stress; supporting antioxidant status is biologically plausible, but dedicated RCT evidence for lowering GGT specifically is limited.
  • Vitamin E -- Same glutathione-recycling/antioxidant rationale as vitamin C -- plausible but not specifically proven for GGT.
  • N-acetylcysteine (NAC) -- A glutathione precursor relevant to GGT's role in glutathione recycling, though dedicated RCT evidence for lowering GGT specifically is limited.

Food first: Reduce/eliminate alcohol (the single strongest lever on GGT), weight loss if fatty liver is present, adequate sleep and stress management.

When to see someone: Elevated GGT with normal ALT/AST can still indicate meaningful alcohol-related or biliary stress -- worth flagging to a physician rather than dismissing.

Read the studies on Gamma-Glutamyl Transferase (GGT)

Albumin, Globulin, Bilirubin & Alkaline Phosphatase (ALP)

Liver protein synthesis and nutritional status (albumin), immune proteins (globulin), red-blood-cell breakdown processing (bilirubin), and liver/bile duct and bone activity (ALP).

Typical range: Standard: Albumin 3.5-5.0 g/dL, Total bilirubin 0.1-1.2 mg/dL, ALP 44-147 U/L (adult, lab-dependent).

Nutrients that move it

  • Dietary Protein -- Albumin synthesis directly requires adequate dietary protein/amino acids; low albumin in the absence of liver or kidney disease can reflect inadequate protein intake or malabsorption.
  • Zinc -- A cofactor in protein synthesis broadly; deficiency can contribute to low albumin in malnourished states, though this is a minor factor compared to overall protein/calorie intake.

Food first: Adequate total protein intake (roughly 0.8-1.2+ g/kg body weight/day depending on activity/age), addressing any underlying malabsorption.

When to see someone: Low albumin can also signal kidney protein loss, chronic inflammation, or liver synthetic dysfunction -- not just a diet issue; needs clinical context.

Iron Panel (Serum Iron, Ferritin, TIBC, Transferrin Saturation)

Cellular Six: Exchange

This marker sits in Exchange -- moving iron across boundaries and handing it between carriers.

Serum iron is circulating iron at the moment of the draw; ferritin reflects iron stores (but is also an acute-phase inflammatory protein); TIBC reflects how much transferrin (the iron-carrier protein) is available; transferrin saturation is the percentage of that capacity currently in use.

Typical range: Ferritin ~15-150 ng/mL (women), ~20-250 ng/mL (men), lab-dependent; serum iron ~60-170 mcg/dL; saturation 20-50%; TIBC 250-450 mcg/dL (conventional ranges, consistent with mainstream lab medicine).

How it is used clinically

Ferritin as a positive acute-phase reactant rising independent of iron status is well established [SOLID] -- this is exactly why mainstream labs pair ferritin with CRP/iron saturation rather than reading it alone. "Anemia of inflammation/chronic disease" is a recognized mainstream diagnosis, and its mechanism (hepcidin-driven iron sequestration in macrophages during inflammation) is well described, but this is attributed to hepcidin/inflammatory signaling, not primarily to copper-ceruloplasmin insufficiency. True tissue iron overload in humans is a well-characterized condition (hereditary hemochromatosis, most often HFE gene mutations, or secondary overload from repeated transfusions) that is diagnosed via genetic testing and/or elevated transferrin saturation and ferritin together -- not inferred from "normal" labs. Hemosiderin itself is a real, recognized iron-storage form (seen on biopsy/imaging in genuine overload states), but using it as a routinely-tested marker of subclinical "hidden" overload in people with normal iron panels is not standard practice.

What this framework claims

Robbins argues "ferritin is nothing, hemosiderin is everything" -- that a "normal" or even low ferritin doesn't rule out tissue iron overload, because without adequate ceruloplasmin ferroxidase activity, iron can't be safely loaded into ferritin's storage shell and instead degrades into hemosiderin, a less-regulated iron-storage form that the functional model treats as a marker of chronic iron mishandling. The functional model also argues that a large share of "anemia of chronic disease/inflammation" is actually a copper-ceruloplasmin problem (iron stuck in tissue, unable to move) rather than a true iron shortage, and warns against iron supplementation in this pattern because it can add fuel to an already-dysregulated system.

Nutrients that move it

  • Copper/ceruloplasmin (mechanistic support for the functional model's model)emerging -- in mice engineered to lack both multicopper ferroxidases (hephaestin and ceruloplasmin), animals developed severe anemia and low serum/spleen iron *alongside* iron overload in the liver, heart, kidney, and duodenum -- a real, published finding that does partially mirror the functional model's "low serum iron with tissue overload" picture. (source: Fuqua BK et al., Cellular and Molecular Gastroenterology and Hepatology, 2018) A separate mouse study found dietary copper deficiency alone (not full ferroxidase gene knockout) caused anemia, duodenal hypoxia, and altered iron-absorption gene expression. (source: Matak P et al., PLOS ONE, 2013) **Important caveat:** these are severe genetic-knockout or induced-deficiency animal models, not evidence that ordinary, mild nutritional copper insufficiency produces this pattern in humans with normal genes -- extrapolating from double-knockout mice to "most fatigued adults have this" is the functional model's leap, not something demonstrated in human trials.
  • Vitamin Csolid -- enhances non-heme iron absorption; meta-analyses of iron-deficiency-anemia trials show a small but real boost to hemoglobin/ferritin when added to iron supplementation. (source: systematic review/meta-analysis, ASH Blood Vessels Thrombosis & Hemostasis, 2024)
  • Riboflavin (B2)emerging -- The functional model claims B2 is required to mobilize iron out of storage. There is real, if limited, supporting evidence: riboflavin-dependent enzymes participate in reductively releasing iron from ferritin, riboflavin deficiency impairs iron mobilization in animal models, and population studies link inadequate riboflavin intake to higher anemia risk; a supplement trial in mildly anemic populations showed riboflavin enhanced the hemoglobin response to standard iron treatment. This is real, but modest, supportive evidence -- not proof that B2 is a primary driver of most iron-panel abnormalities. (source: Nutrition Reviews, 2023; Jiangsu Nutrition Study, PMC3923059)

Food first: Heme iron (red meat, poultry, fish) is more bioavailable than plant iron; pair plant iron with vitamin C; ensure adequate riboflavin (dairy, eggs, leafy greens, organ meats) and copper (liver, shellfish) as supporting cofactors.

When to see someone: Iron overload -- from hereditary haemochromatosis or from sustained over-supplementation -- causes irreversible damage to the liver, heart and pancreas, so a confirmed deficiency should come before iron is added. A genuinely abnormal panel, particularly a raised transferrin saturation with a raised ferritin, warrants a standard workup including consideration of HFE genetic testing rather than a self-directed mineral protocol. Ferritin is always read alongside CRP.

High-Sensitivity C-Reactive Protein (hs-CRP)

Cellular Six: Maintain

This marker sits in Maintain -- the cleanup and defence system, and whether it is switched on.

A liver-produced marker of systemic inflammation, standard in cardiology risk assessment.

Typical range: <1.0 mg/L low cardiovascular risk, 1.0-3.0 average, >3.0 high risk (standard AHA/CDC cutoffs).

How it is used clinically

This particular use -- pairing CRP with ferritin to sort out whether ferritin is elevated due to inflammation versus true iron stores -- is actually standard, mainstream laboratory-medicine practice, not an the functional model-specific innovation. **[SOLID]** Where the functional model diverges is in attributing the underlying inflammation itself primarily to copper/iron/magnesium mineral dysregulation rather than the broader, well-established list of drivers (diet, adiposity, infection, autoimmune activity, smoking, poor sleep, etc.).

What this framework claims

the functional model uses hs-CRP as a companion marker to the iron panel -- specifically to help decide whether an elevated or "normal" ferritin is being driven by inflammation (masking a true iron problem) rather than genuine iron stores, and treats persistent inflammation itself as a downstream sign of the mineral-dysregulation/oxidative-stress model.

Food first: Mediterranean-pattern eating, weight management, smoking cessation -- these move hs-CRP more reliably than any single mineral intervention.

When to see someone: hs-CRP rises with any acute infection, injury, or recent exercise/dental work -- a single elevated reading isn't meaningful in isolation.

Read the studies on High-Sensitivity C-Reactive Protein (hs-CRP)

Serum Ceruloplasmin

Cellular Six: Exchange

This marker sits in Exchange -- moving iron across boundaries and handing it between carriers.

The major copper-transport protein made in the liver; it carries the large majority of circulating copper and functions as a ferroxidase enzyme, oxidizing ferrous iron (Fe2+) to ferric iron (Fe3+) so iron can bind to transferrin and be moved and stored safely. This ferroxidase role is well-established, mainstream biochemistry. **[SOLID]** (source: Vashchenko G, MacGillivray RT, Nutrients, 2013; StatPearls, NCBI Bookshelf)

Typical range: Roughly 20-40 mg/dL in most adult reference ranges (some labs cite 27-37 mg/dL); varies by assay.

How it is used clinically

Ceruloplasmin is primarily used clinically to screen for Wilson's disease (characteristically low) and to help confirm copper deficiency; it is also a well-established positive acute-phase reactant [SOLID] -- levels rise during infection, inflammation, tissue injury, and pregnancy/estrogen exposure. This matters directly for the functional model's framing: a "normal" or even elevated ceruloplasmin during an inflammatory state doesn't necessarily mean someone is copper-replete and metabolically healthy, and a "low-normal" reading isn't automatically a sign of an underlying, correctable "bioavailable copper" deficiency the way the functional model frames it. (cite: StatPearls, NCBI Bookshelf; Inflammation Research review)

What this framework claims

Robbins treats ceruloplasmin as the single most important lab in the protocol -- low or "sub-optimal" ceruloplasmin is, in the functional model's model, the functional bottleneck that lets iron and copper go "unbound" and drive oxidative stress and fatigue. the functional model asserts ceruloplasmin synthesis specifically requires adequate magnesium plus retinol (true vitamin A), and pushes cod liver oil and magnesium supplementation on this basis from day one of the protocol.

Nutrients that move it

  • Coppersolid -- copper is ceruloplasmin's direct structural substrate (six copper atoms per molecule); without adequate copper, ceruloplasmin cannot be made, regardless of other nutrient status.
  • Retinol/vitamin Aemerging -- retinoic acid (a vitamin A metabolite) has been shown to induce ceruloplasmin gene expression and rescue ceruloplasmin secretion specifically in Wilson's-disease-patient-derived liver cells in a lab-dish (in vitro) model. (source: PMC9616579) This gives the functional model's retinol-ceruloplasmin pairing a real mechanistic basis, but it's disease-specific, cell-culture evidence -- it does not show that giving healthy or mildly fatigued people extra retinol meaningfully raises their ceruloplasmin or resolves symptoms.
  • Magnesium (functional-model assertion, not established in peer-reviewed literature) -- Robbins states magnesium is directly required for ceruloplasmin synthesis. Magnesium's broad role as a cofactor in protein synthesis and hundreds of enzymatic reactions is [SOLID], well-documented physiology, but a specific, dedicated magnesium-to-ceruloplasmin-synthesis pathway was not found in the peer-reviewed literature searched for this file. This specific claim should be treated as the functional model's extrapolation from magnesium's general biochemical importance, not a demonstrated mechanism.

Food first: Copper-rich foods (liver, shellfish) support the substrate side; retinol-rich foods (liver, egg yolk, dairy fat, cod liver oil) are the the functional model-favored vitamin A source, on the theory that preformed retinol (not beta-carotene) is what's needed.

When to see someone: A low ceruloplasmin together with a high non-ceruloplasmin-bound ("free") copper and/or neurological or liver symptoms warrants a Wilson's disease workup with a specialist -- this is a serious genetic condition, not something to self-manage with a mineral protocol.

Read the studies on Serum Ceruloplasmin

Serum Copper

Cellular Six: Exchange

This marker sits in Exchange -- moving iron across boundaries and handing it between carriers.

Total circulating copper, of which roughly 95% is normally bound to ceruloplasmin and about 5% is loosely bound to albumin and small peptides (the "free" or "non-ceruloplasmin-bound" fraction).

Typical range: Roughly 70-140 mcg/dL for men, 80-155 mcg/dL for women (ranges vary somewhat by lab/method).

How it is used clinically

Serum copper is used mainly to screen for overt copper deficiency (rare, usually from malabsorption, bariatric surgery, or chronic excess zinc intake) or Wilson's disease/copper overload, alongside ceruloplasmin. It's a recognized positive acute-phase reactant [SOLID] -- it rises with inflammation, infection, pregnancy, and estrogen (including oral contraceptives), which is a real and important interpretive caveat but is a different mechanism than the functional model's "bioavailability" framing.

What this framework claims

Robbins argues total serum copper alone is close to meaningless, because it doesn't tell you how much of that copper is actually "bioavailable" -- i.e., properly incorporated into functional ceruloplasmin versus floating "unbound." the functional model treats a "normal" total copper as potentially masking a functional copper deficiency.

Nutrients that move it

  • Zinc antagonismsolid -- chronic high-dose zinc intake (>40 mg/day) induces intestinal metallothionein, which binds copper and blocks its absorption; this is a well-documented, mainstream-recognized cause of copper deficiency, not an the functional model-specific claim.
  • Retinol/vitamin Aemerging -- see Ceruloplasmin section below; retinoic acid can induce ceruloplasmin gene expression in cell models, which is the mechanistic basis for the functional model's copper + retinol pairing, but this is early-stage/cell-culture evidence, not a clinical trial in humans with "low energy."

Food first: Beef/chicken liver, oysters and shellfish, cacao are copper-dense whole foods the functional model favors; standard nutrition guidance agrees these are good copper sources for people with confirmed low intake or deficiency.

When to see someone: Copper has a genuinely narrow window in both directions. Overload is Wilson's disease, a genetic condition causing serious liver and neurological damage that needs hepatology or genetics management. A raised serum copper on its own should prompt checking ceruloplasmin and ruling out inflammation, pregnancy or oestrogen therapy -- all of which raise it -- before it is read as dysregulation.

Fasting Insulin

The level of insulin in your blood after an overnight fast. When cells respond well to insulin, it takes only a little to keep glucose in line, so the number is low; when cells respond less well (insulin resistance), the pancreas compensates by releasing more, and fasting insulin rises long before glucose does. This is why it is treated as an early-warning marker rather than an afterthought -- a large pooled analysis of prospective cohort studies found that a higher fasting insulin level tracks with greater long-term risk of high blood pressure and coronary heart disease. (source: fasting insulin and incidence of hypertension, stroke, and coronary heart disease -- meta-analysis of prospective cohort studies, PMID 24132974)

Typical range: Conventional lab range: roughly 2-25 microIU/mL (varies widely by lab and assay; many labs flag values above ~25). Functional optimal (opinion): a fasting insulin in the low single digits (often cited as ~2-6 microIU/mL) is described by functional-medicine practitioners as ideal -- this is an opinion range, not an official diagnostic cutoff, and fasting insulin is meant to be read alongside glucose (as HOMA-IR), not in isolation.

Nutrients that move it

  • Soluble fibersolid -- summarizing dozens of meta-analyses covering tens of thousands of people, higher dietary fiber intake was linked to lower fasting insulin (alongside lower fasting glucose, HOMA-IR, and HbA1c), partly by slowing how fast a meal's sugar arrives. (source: dietary fiber intake and cardiovascular risk factors -- umbrella review of meta-analyses of RCTs, PMC9511151)
  • Magnesiumemerging -- a cofactor the body uses throughout normal glucose and energy metabolism, and one of the more common shortfalls in a modern diet; a meta-analysis of RCTs in type 2 diabetes found magnesium supplementation modestly improved fasting glucose and HbA1c, and low magnesium status tracks with insulin resistance. (source: magnesium and glycemic control, meta-analysis of RCTs, PMC7784187)
  • Chromiumcontested -- a trace mineral involved in normal carbohydrate metabolism; best thought of as adequacy rather than a lever to push, because the RCT evidence in glycemic markers is genuinely conflicting. (source: conflicting meta-analyses of chromium picolinate RCTs, clinical-nutrition systematic reviews)

Food first: Front-load fiber and protein, put vegetables first in a meal, and choose slower (lower-glycemic) carbohydrates more often than not -- the plate is where the insulin signal is made easier to hear. Ensure dietary magnesium adequacy (leafy greens, nuts, seeds, legumes) rather than empiric megadosing.

When to see someone: Fasting insulin assays vary a lot between labs, so track trend on the same lab rather than comparing a single number across labs. A single reading is a piece of a picture a clinician interprets, never a self-diagnosis. Insulin supplements do not exist over the counter -- nothing here raises or lowers insulin as a treatment; the levers work by improving how the tissues respond to it.

Read the studies on Fasting Insulin

Triglycerides

The main fat carried in the blood. When insulin is not working well, the liver tends to pour out more triglycerides, so a rising triglyceride level is part of the insulin-resistance fingerprint -- and it is one of the five metabolic-syndrome findings for that reason. (source: a comprehensive definition for metabolic syndrome (NCEP ATP III), PMC2675814)

Typical range: Conventional: below 150 mg/dL is desirable, 150-199 mg/dL borderline-high, and ≥200 mg/dL high. Functional optimal (opinion): some practitioners prefer triglycerides under ~100 mg/dL (or even ~70) as a sign of good insulin sensitivity -- opinion, not an official cutoff. Triglycerides are strongly affected by recent food and alcohol, so this should be a true fasting value.

Nutrients that move it

  • Omega-3 (EPA and DHA)solid -- the long-chain omega-3 fats are well established to lower serum triglycerides in a dose-dependent way and are relevant to the body's normal inflammatory balance; this is one of the better-supported nutrient effects on any marker in this file (see the ingredient page for the trial evidence).
  • Soluble fiberemerging -- fiber's curve-flattening and lipid effects tend to nudge triglycerides down as part of the broader improvement in glucose and insulin handling. (source: dietary fiber intake and cardiovascular risk factors -- umbrella review, PMC9511151)

Food first: Oily fish (or an EPA/DHA source) for the omega-3 side, less refined and liquid sugar (which the liver converts efficiently to triglycerides), less alcohol, and the same fiber-first plate. Movement and reducing excess refined carbohydrate move triglycerides more than most single supplements.

When to see someone: A non-fasting draw or recent alcohol can inflate triglycerides substantially -- confirm the sample was truly fasting before reading it. Very high triglycerides are a medical matter (pancreatitis risk) that belongs with a clinician, not a nutrition experiment.

What moves it

The levers the library records for this panel, positive and null findings side by side. Nothing here treats, prevents or reverses anything.

  • The eating pattern

    Fasting and Mediterranean-pattern interventions reduced liver enzymes and steatosis in metabolic fatty liver disease, with the Mediterranean pattern also improving liver stiffness on imagingHH-141340; Mediterranean and low-fat diets were equally effective at reducing liver fat and enzymes, so the choice can follow preferenceHH-141302; the DASH pattern lowered AST across six randomized trialsHH-136179. Held beside those: one meta-analysis found the Mediterranean diet lowered cholesterol and stiffness markers but not the enzymes themselvesHH-141073. An umbrella review ranked diet and exercise above most of the drugs tested for reducing liver fatHH-258997.

  • Movement

    Across 26 randomized trials, exercise training reduced ALT moderately and AST slightly, aerobic work more than resistance work for ALTHH-109781; structured aerobic and resistance programs reduced steatosis often without substantial weight lossHH-141182.

  • Sugar, specifically the drinkable kind

    Adding excess energy from sugar-sweetened beverages raised liver fat and ALT in controlled trialsHH-138882; across 35,705 people, sugar-sweetened beverage intake carried 1.39-fold higher odds of fatty liver, rising with intakeHH-138165.

  • Fiber

    Twenty-four grams of dietary fiber a day improved glycemic control and reduced liver fibrosis markers in type 2 diabetes with fatty liverHH-151589; a low-carbohydrate, high-fiber diet with education reduced liver enzymes more than education alone in 44 patientsHH-141126.

  • Coffee

    Coffee did not change fatty liver incidence in the general population, but was linked to 35 percent lower odds of significant fibrosis in people who already had itHH-140482. Held beside it: in randomized trials, coffee or coffee extract did not change ALT or ASTHH-140572.

  • Vitamin E

    An umbrella review found vitamin E lowered transaminases, fibrosis and steatosis in non-alcoholic fatty liver disease, with the fibrosis effect above 600 IU a dayHH-141855; a systematic review of eight randomized trials found enzymes and steatosis improved but fibrosis did notHH-141905. Both readings are kept.

  • Curcumin, with its quality grade

    Fifteen randomized trials found curcumin reduced ALT and AST in fatty liver disease and did not move ALPHH-142179; a GRADE-assessed review of 31 trials rated the same effect low to very low certainty and found no change in GGTHH-370475.

  • Omega-3 from plants, probiotics, and what did not move

    Plant-based omega-3 with lifestyle change reduced ALT and triglycerides across six trialsHH-3930; probiotic, prebiotic and synbiotic supplementation reduced liver enzymes and inflammatory markers across 34 randomized trialsHH-370584. The nulls: N-acetylcysteine did not change steatosis or enzymes in eight weeks, though it lowered glucose, insulin resistance and CRP and raised glutathioneHH-370573; alpha-lipoic acid did not improve enzymes, lipids or glucose across seven trialsHH-105992; berberine with silymarin did not change ALT or AST across fiveHH-141528.

  • Selenium, U-shaped

    Whole-blood selenium showed a U-shaped association with liver fat in NHANES, lowest risk near 140 micrograms per liter, possibly explained by mercury-selenium antagonism (a preprint)HH-125986. More is not the direction.

What no one orders

The markers in this panel a standard visit rarely includes, and why each one changes what the rest of the panel means.

  • Gamma-Glutamyl Transferase (GGT)

    The earliest enzyme to move with alcohol and oxidative load, and the one most panels drop; it beat AST and ALT for detecting active drinking at a cutoff of 81 U/LHH-114095.

  • Iron Panel (Serum Iron, Ferritin, TIBC, Transferrin Saturation)

    Transferrin saturation is what separates true iron overload from a ferritin raised by inflammation; the 19-month case with normal saturation and normal MRI iron is the trap in printHH-102263.

  • Serum Ceruloplasmin

    Low in Wilson disease and in copper deficiency, and the enzyme that lets iron be moved at allHH-0194.

The cofactors

What your Liver panel leaves out

The standard numbers are only half of how a marker moves. The other half is its cofactors: the nutrients the body needs to make it, use it or clear it. A routine blood count, metabolic panel, lipid panel and TSH do not measure them. These are the tests that would, for the markers on this page.

Derived from the cofactor rows in the library (a nutrient is listed when a study edge or at least 50 studies tie it to a marker here). Ordering links are lab testing only; ask your clinician what fits you.

Toxicity is inside every panel

What toxins can do to the liver

A metal, a mold product or a chemical can move the numbers on this page the same way a missing nutrient does, and the body spends its cofactors dealing with them. These are the simple tests. A result is a measurement to take to a clinician, never a diagnosis.

  • Heavy metals (lead, mercury, cadmium, arsenic)

    454 studies in this library name it alongside the liver. HH-8654HH-12688HH-13354

    The test: Blood shows recent exposure and is the standard for lead. Urine is the usual sample for cadmium, and a speciated urine test separates the forms of arsenic. Hair varies a lot between labs, so it is read beside blood or urine, never alone.

    Order it: Walk-In Lab Lead Blood Test; Walk-In Lab Mercury Blood Test; Walk-In Lab Heavy Metals Profile II Blood Test; Labcorp OnDemand Standard Heavy Metals Test; Walk-In Lab Hair Toxic and Essential Elements Kit - Doctor's Data Test Kit. See How to get measured for prices and dates.

  • Aluminum

    47 studies in this library name it alongside the liver. HH-39158HH-39258HH-83334

    The test: Serum aluminum is the standard test, but kidney function changes how it reads. Urine and hair are used too, and hair sits in the 43-element kit below.

    Order it: Walk-In Lab Hair Toxic and Essential Elements Kit - Doctor's Data Test Kit. See How to get measured for prices and dates.

  • Glyphosate (urine glyphosate and AMPA)

    51 studies in this library name it alongside the liver. HH-26363HH-26368HH-26380

    The test: A random or first-morning urine sample that measures glyphosate and its breakdown product AMPA.

    Ask for: a urine glyphosate and AMPA test. No direct-access page was read for it, so no vendor is named here.

  • Mold (urine mycotoxins)

    388 studies in this library name it alongside the liver. HH-4697HH-13155HH-21104

    The test: A urine panel that measures the mycotoxins (mold products) your body has excreted.

    Ask for: a urine mycotoxin test. No direct-access page was read for it, so no vendor is named here.

  • PFAS (forever chemicals)

    180 studies in this library name it alongside the liver. HH-2791HH-17606HH-25930

    The test: A serum panel that reports several PFAS compounds separately, not one number, since there are thousands of them.

    Ask for: a serum PFAS panel. No direct-access page was read for it, so no vendor is named here.

Mold and metals: 29 of the 1,721 approved mycotoxin studies in this library also name a metal. HH-33652HH-33753HH-128748 The library records them in the same studies; it does not yet show that one drives the other.

How to get measured

The Liver markers as a direct-access order in three sizes. Each card names what it covers, what it still misses, and the provider tests that carry it, with the price read on the provider's page and the date it was read.

Good is the minimum set, Better the fuller set, Best the most complete set this page can point at. The tiers are about coverage, not about which number matters most for you.

Good (the minimum set)

The liver chemistry with GGT

ALT, AST, albumin, bilirubin and ALP from the CMP or a hepatic panel, with the enzyme most panels drop.

Covers: ALT & AST (Liver Enzymes) · Albumin, Globulin, Bilirubin & Alkaline Phosphatase (ALP) · Gamma-Glutamyl Transferase (GGT)

Misses: No iron picture, no inflammation number, no insulin or triglycerides.

Better (the fuller set)

Add the iron panel, hs-CRP, fasting insulin and the lipid panel

Transferrin saturation beside ferritin and hs-CRP, and the insulin and triglycerides a fatty liver travels with.

Covers: Iron Panel (Serum Iron, Ferritin, TIBC, Transferrin Saturation) · High-Sensitivity C-Reactive Protein (hs-CRP) · Fasting Insulin · Triglycerides

Misses: No copper or ceruloplasmin.

Best (the most complete set)

Add ceruloplasmin and copper

The copper enzyme, low in Wilson disease and in copper deficiency.

Covers: Serum Ceruloplasmin · Serum Copper

Misses: Nothing in this panel is left without an orderable test.

What no one orders, and where it is ordered

Which states

State law limits direct-access testing in some states (New York, New Jersey and Rhode Island are named by most providers; Hawaii, Arizona, Maryland and Massachusetts by some). Each provider's own line is quoted below, and the checkout is where it is enforced.

  • Walk-In Lab: Walk-In Lab's FAQ: not offered through Labcorp in NY, NJ, RI, MD and MA, and not through the other national lab network in AZ, NY, NJ and RI (paraphrased; the FAQ names both labs). source · +$6.00 per order physician fee, shown on every product page.
  • Labcorp OnDemand: "Available in all 50 states" to consumers 18 or older, on Labcorp's own page. source · No separate order fee was shown on the pages read.
  • Quest (questhealth.com): "Lab tests are not currently available in Arizona, Hawaii, and Puerto Rico." In Arizona the page points to Sonora Quest's My Lab ReQuest. source · +$6.00 Physician Service Fee per order, shown on every product page.
  • Ulta Lab Tests: "Currently, Hawaii, New York, New Jersey and Rhode Island state laws prohibit direct-access testing." source · No separate order fee was shown on the pages read.
  • Request A Test: The site's customer notice: "All lab requests and results are reviewed by a physician licensed in your state of residence. For NY, NJ and RI clients, Request A Test cannot directly bill for laboratory testing." Lab availability in NY, NJ, RI and AZ is checked at checkout. source · +$4.00 per order service fee, shown on every product page.
  • A direct-access order is a lab test without a visit: the provider supplies the order, you are drawn at a Labcorp or Quest patient centre or collect at home, and the results go to you.
  • The Lab Atlas never sees a result unless you enter it yourself. Nothing here is sent to a provider and nothing comes back.
  • A result outside the interval is a conversation with a clinician, not a verdict. The panel pages say what each marker measures and what it cannot; this page only says where to get the number.
  • Every price was read on the provider's page on the date shown and carries its link. Prices move; the date is part of the number. Per-order fees are listed by provider and sit on top.
