ALT
Nutrients connected to ALT
A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.
- Green tea extract and EGCGDocumented risk
Liver enzyme markers such as ALT rose in trials of high-dose EGCG supplements, which is why liver tests are used to watch for harm.
- He shou wuDocumented risk
ALT was raised in all 18 people in a case series of liver injury after this root; blood tests are how the injury is detected.
- Curcumin (turmeric supplements)Documented risk
Liver tests such as ALT are used to detect supplement-associated liver injury; most patients in one series had raised transaminases, which returned to normal after stopping.
- Milk ThistlePreliminary or mixed
ALT is a liver enzyme used to track liver inflammation. In a US trial of 154 adults with hepatitis C, silymarin did not lower ALT more than placebo.
- Gotu kolaDocumented risk
In the case series, ALT was very high (324 to 1694 U/L) when liver injury occurred; liver blood tests are how it is detected.
- SchisandraDocumented risk
MSK says schisandra can lower ALT on lab tests, which could affect how liver tests are read.
- TribulusDocumented risk
Very high liver enzymes were reported in case reports of tribulus use.
- CorydalisDocumented risk
Liver tests such as ALT rose in the reported cases of corydalis-linked liver injury, and in one person rose again on restarting the product.
- Reishi (lingzhi)Documented risk
Raised liver enzymes (transaminases) were seen in a reported case of reishi-powder hepatitis, so liver tests are how an injury would show; the cause in a case cannot be proved from one report.
- Almond mushroom (Agaricus subrufescens)Documented risk
Liver enzymes rose in case reports of liver injury; one four-patient pilot reported falling enzymes in hepatitis B. Tell a clinician about the product before liver tests.
- Baikal skullcapDocumented risk
Liver blood tests such as ALT are how root-related liver injury is detected; in a case report ALT fell by more than half within days of stopping the herb.
- Garcinia cambogiaDocumented risk
Reported injury shows raised ALT and AST; a case report describes ALT of 4,664 U/L. Trials in a meta-analysis found no change in ALT overall.
- Antrodia camphorataPreliminary or mixed
ALT was the main outcome in a 44-adult trial (no overall change); liver-fat scores improved in a separate 28-person trial.
- Usnea (old man's beard lichen)Documented risk
Case reports describe large rises in ALT with usnic acid products, a sign of liver injury.
- TurmericDocumented risk
Turmeric liver injury was typically hepatocellular, which liver enzyme tests such as ALT would show; the abstract does not name ALT.
- Bakuchi (babchi)Documented risk
Liver enzymes such as ALT are used to check for liver injury in the case reports and animal studies read.
- Xanthium (cang er zi, cocklebur)Documented risk
ALT rose markedly in the fatal case and in mice given the toxin.
- Destroying angelDocumented risk
Liver enzymes such as ALT rise during amatoxin poisoning, often after the stomach symptoms ease; in one fatal case they rose from 54 to 824 u/L over a day.
- Greater celandineDocumented risk
Case reports show raised ALT in greater celandine liver injury, and German rules call for liver tests if use passes 4 weeks. A blood test cannot show the herb is safe.
- Schisandra TeaDocumented risk
Schisandra can lower ALT and AST readings on lab tests, which may affect how liver tests are read.
- Joint Formulas (Glucosamine, Chondroitin, MSM, Turmeric)Documented risk
Liver tests rose in turmeric liver-injury cases and normalized after stopping.
- TaurinePreliminary or mixed
The 2026 meta-analysis reported lower ALT with taurine supplements, largely in people with liver or metabolic problems.
- Beta-alanineDocumented risk
Studies found a small average rise in ALT, staying within reference ranges.
Liver enzyme ALT rose within three weeks in men on a choline-restricted diet. ALT is not a test for choline status and rises for many other reasons.
- Guduchi (giloy)Documented risk
In a reported case, liver enzymes (transaminases) were severely raised during guduchi use and fell by more than half within two weeks of stopping. The report does not name ALT alone.
- KavaDocumented risk
Liver blood tests can be raised in kava users, and abnormal ALT was reported in some studies of heavy drinkers. A 2020 trial found more abnormal liver tests with kava than placebo.
- RooibosDocumented risk
Raised liver enzymes were reported in rooibos liver case reports and returned to normal after stopping.
- KutkiPreliminary or mixed
The 1996 trial reported lower liver enzymes (SGPT/ALT) in people with acute viral hepatitis given a kutki extract versus placebo; one small trial.
- KratomDocumented risk
Raised ALT appeared in a healthy-volunteer trial after repeated doses and in liver-injury case reports; the meaning for ordinary users is not known.
- Bay leafDocumented risk
In the case report, ALT rose to 357 U/L and fell after bay leaf tea was stopped; one patient.
- King tuber mushroomLab or animal research only
ALT fell in rats with chemically induced liver damage; mouse extract did not raise ALT.
- Thuja (northern white cedar)Documented risk
Liver enzymes (ALT and AST) were raised in the one case report of probable liver injury with thuja and black cohosh.
- BoldoDocumented risk
Case reports of boldo-related liver injury describe raised liver enzymes; a formal causality score was not given.
- MayappleDocumented risk
IPCS notes liver enzymes may rise after poisoning.
- Capillary wormwood (yin chen hao)Preliminary or mixed
In the cited trials of the formula, ALT fell more than with usual drugs; ALT is also what to watch if a herb injures the liver. Evidence is for the formula.
- Tonka beanDocumented risk
The 2022 review reports transaminase (liver enzyme) rises in a small share of patients on coumarin drug doses; it does not name ALT alone.
- Green TeaDocumented risk
Liver enzymes (transaminases) rose in trials of extract at 800 mg EGCG a day or more; not shown for the drink.
- MatchaDocumented risk
Transaminases rose with high-dose green tea extract, not shown for matcha.
- Rooibos TeaDocumented risk
Raised liver enzymes were reported in a case with large amounts; normalized after stopping.
- Ashwagandha TeaDocumented risk
Liver tests are raised in the liver injury reports; seek care if jaundice appears.
- Mushroom Blends and Mushroom CoffeeDocumented risk
Liver enzymes were high in the reishi plus alcohol case and normal again by two weeks.
