Top 10 Evidence-Based Recommendations
We analyzed meta-analyses and the largest RCTs in fatty liver (NAFLD/MASLD and biopsy-proven NASH), prioritizing meaningful liver-fat loss (MRI/CT/ultrasound), histology where available, enzyme drops, safety, and practicality from >60 human trials. No fluff, no affiliate picks—just what moves the needle, fast and safely, with [^] citations throughout.

Ranked Recommendations
#1Top Choice
The reliable fat-squeezer for your liver
Dose: 2–4 g/day EPA+DHA with meals for 12–24 weeks
Time to Effect: 8–12 weeks for liver fat; 4–8 weeks for triglycerides
How It Works
Evidence
Best for:High triglycerides, MRI/ultrasound-proven steatosis, those wanting cardio-metabolic upside too
Caution:Fishy burps; mild antiplatelet effect—use caution with anticoagulants
Tip:Aim for products listing EPA and DHA milligrams (not just "fish oil"); triglyceride or re-esterified TG forms are well absorbed.
#2Strong Alternative
The only supplement with biopsy-proven NASH response
Dose: 800 IU/day RRR-α-tocopherol for 96 weeks (non-diabetic NASH)
Time to Effect: 24–48 weeks for histology; 8–12 weeks for enzymes
How It Works
Potent antioxidant dampening lipid peroxidation and inflammatory injury that drive ballooning and NASH activity. [1]
Evidence
The NIH PIVENS RCT showed 43% NASH improvement vs 19% placebo over 96 weeks (non-diabetic adults); fibrosis not improved. Not generalizable to diabetics. [1]
Best for:Biopsy-proven NASH without diabetes, under clinician guidance
Caution:Possible ↑ hemorrhagic stroke and prostate cancer risk signals in other populations; discuss risks/benefits and avoid mega-dosing unnecessarily. [9]
Tip:Use natural RRR-α-tocopherol; reassess need at 6–12 months with your clinician.
#3Worth Considering
The insulin-and-lipid fixer that trims liver fat
Dose: 500 mg three times daily with meals (1.5 g/day) for 12–16 weeks
Time to Effect: 4–8 weeks for enzymes and lipids; 12–16 weeks for liver fat
How It Works
Evidence
Best for:NAFLD with insulin resistance, prediabetes/T2D, atherogenic lipids
Caution:GI upset; may interact with CYP3A4/P-gp drugs and lower glucose—monitor if on hypoglycemics
Tip:Choose berberine HCl from reputable brands; split dosing tames GI effects.
#4
Vitamin E's under-the-radar cousin with enzyme wins
Dose: 300 mg twice daily for 24 weeks
Time to Effect: 8–12 weeks for enzymes; 24 weeks for steatosis grade
How It Works
Antioxidant/anti-inflammatory effects distinct from tocopherols; modulates SREBP and NF-κB pathways tied to steatosis. [5]
Evidence
Placebo-controlled RCT (24 weeks) showed improvements in ALT/AST, inflammation markers, and ultrasound steatosis vs placebo. [5]
Best for:Those who can't take high-dose α-tocopherol but want redox support
Caution:Generally well tolerated; avoid stacking with high-dose α-tocopherol unless supervised
Tip:Annatto-derived δ-tocotrienol products typically provide the studied profile.
#5
Turns fat into fuel inside liver mitochondria
Dose: 1–2 g/day (adults) for 8–24 weeks
Time to Effect: 4–8 weeks for enzymes; 8–12 weeks for triglycerides
How It Works
Shuttles long-chain fatty acids into mitochondria, boosting β-oxidation and lowering hepatic fat accumulation. [2]
Evidence
Meta-analysis of 8 RCTs shows significant ALT/AST reductions and triglyceride benefits, with stronger effects in adults. [2]
Best for:Fatigue plus NAFLD, high triglycerides, those intolerant to fish oil
Caution:Fishy odor, mild GI upset
Tip:Acetyl-L-carnitine is also effective; take with meals to reduce GI issues.
#6
Inflammation down, enzymes down
Dose: 1000–1500 mg/day standardized curcuminoids with piperine/phospholipid for 8–12 weeks
Time to Effect: 4–8 weeks for enzymes; 8–12 weeks for ultrasound severity
How It Works
Evidence
Best for:People prioritizing inflammation, enzymes, and metabolic markers
Caution:Gallbladder disease risk, anticoagulant interactions at high doses
Tip:Pick phytosomal or piperine-enhanced formulas; plain turmeric won't cut it.
#7
Fix the gut–liver axis to ease liver injury
#8
Solid for enzymes, mixed for histology
#9
Supports VLDL export—fat needs a ride out
#10
Antioxidant brew that lightens liver fat

Combination Strategies
Metabolic Fix + Fat Out Stack
Components: Berberine 500 mg TID + Omega-3 EPA/DHA 2–4 g/day + L‑Carnitine 1–2 g/day
Targets the 3 biggest hepatic fat drivers—insulin resistance (berberine), triglyceride overflow (EPA/DHA), and sluggish β-oxidation (carnitine)—delivering additive drops in enzymes and liver fat. [10][12][20][2]
With meals: berberine 500 mg three times daily; fish oil split BID; L‑carnitine once or split BID. Run 12 weeks, recheck ALT/AST and ultrasound/MRI if available.
Inflammation & Stiffness Stack
Components: Curcumin 1000–1500 mg/day (enhanced) + Probiotic multi‑strain 10–20B CFU/day + Silymarin 420–700 mg/day
Curcumin and silymarin calm hepatocyte injury; probiotics reduce gut-derived inflammation and modestly improve fibrosis indices; together they address enzyme elevation and liver stiffness. [3][7][16][25]
Take curcumin and silymarin with food; probiotic daily for at least 12–24 weeks. Assess FibroScan (LSM) at baseline and ~6 months.
NASH (Doctor-Supervised) Stack
Components: Vitamin E 800 IU/day (non‑diabetic NASH) + Omega-3 EPA/DHA 2–4 g/day
Vitamin E is the only supplement with RCT histologic NASH improvement (non-diabetics); omega-3s layer on liver-fat and triglyceride reductions for cardiometabolic protection. [1][10][12]
Only if non‑diabetic and approved by your hepatology team. Take daily with meals; reassess at 6–12 months for continuation.
Shopping Guide
Form Matters
- •Omega-3: choose EPA/DHA totals (≥1 g EPA+DHA per serving), re-esterified TG or triglyceride form absorbs well.
- •Curcumin: phytosomal (Meriva) or with piperine for absorption; plain turmeric is weak.
- •Silymarin: silybin-phosphatidylcholine (phytosome) boosts bioavailability.
- •Probiotics: multi-strain Lactobacillus+Bifidobacterium with CFU listed at expiry, not manufacture.
- •Vitamin E: natural RRR-α-tocopherol (not DL-) if used under medical guidance.
Quality Indicators
- •IFOS/GOED or USP-verified fish oil; oxidation markers (peroxide/aniso) available on request.
- •Botanicals standardized to actives (e.g., ≥95% curcuminoids; ≥70–80% silymarin).
- •COAs showing heavy metals, microbes, and solvent residues—especially for green tea extracts.
Avoid
- •'Liver detox' proprietary blends without exact milligrams.
- •Mega-dose promises ('lose 50% liver fat in 2 weeks').
- •No third-party testing (NSF, USP, Informed Choice) for oils and botanicals.
- •Under-dosed berberine (<1000 mg/day total) or fish oil labeled only as '1000 mg fish oil' without EPA/DHA.
Overrated Options
These supplements are often marketed for Fatty Liver (NAFLD/MASLD and NASH) but have limited evidence:
Resveratrol
Multiple meta-analyses in NAFLD show trivial or no benefit on enzymes, fat, or lipids; some analyses even show worse LDL/TC vs placebo. [28][29][30][31]
Vitamin D (high-dose)
Mixed data; recent RCTs in NAFLD/T2D show biomarker shifts but inconsistent effects on liver fat/enzymes—insufficient to rank among top options. [23]
Important Considerations
Supplements support but don't cure fatty liver. Verify diagnoses (NAFLD vs alcoholic liver disease, viral hepatitis, autoimmune, drug-induced). If you have cirrhosis, are pregnant, on anticoagulants, or take multiple prescriptions, talk to your clinician first. Recheck ALT/AST in 8–12 weeks and consider imaging (FibroScan CAP/LSM, MRI-PDFF) to confirm response.
How we chose these supplements
Common Questions
How fast can supplements reduce liver fat?
Most trials show changes by 8–12 weeks; histology-level NASH responses (vitamin E) take ~12–24 months. [1][10]
Which single supplement helps most people with fatty liver?
Omega-3 EPA/DHA—consistent imaging and enzyme improvements, plus cardiovascular benefits. [10][11]
Is vitamin E right for me?
Only consider 800 IU/day if you have biopsy-proven NASH and no diabetes, under medical supervision. [1]
Can I take berberine and fish oil together?
Yes—different mechanisms; the combo targets insulin resistance and triglyceride overflow. [10][20]
Do these replace diet and exercise?
No. All RCTs layered on lifestyle. Weight loss of 7–10% remains the biggest lever; supplements are add-ons.
