Silymarin

Why this matters

№ 01Supports liver cell regeneration and protection*
№ 02Powerful antioxidant for liver health*
№ 03Promotes healthy detoxification pathways*

Protocol & dosing

Silymarin's hepatoprotective and antioxidant effects are substrate-level — no receptor tolerance.

Recommended Protocol

Daily

Take every day. Effect compounds over weeks.

Daily dose: 1 capsule
Half-life (t½): ~6–8 hours (silybin)

Why it cycles

Milk thistle's silymarin complex (silybin, silydianin, silychristin) exerts hepatoprotective effects via NF-κB suppression, Nrf2 activation, and direct free-radical scavenging. These are enzyme-inhibition and antioxidant substrate mechanisms — no receptor agonism — and clinical trials of up to 41 months show no tolerance to liver-enzyme normalization benefits.

Driver: NF-κB suppression + Nrf2 antioxidant gene expression (silybin)

Off-period: No off period needed. Stopping removes ongoing NF-κB suppression and Nrf2 support for hepatic antioxidant defense, gradually increasing liver oxidative burden. No resensitization benefit.

What the research shows.

2 citations

“Meta-analysis of 8 RCTs (n=587) evaluating silymarin (from milk thistle, 140-600 mg/day for 1-6 months) on liver enzymes. Silymarin significantly reduced ALT (WMD=-4.19 U/L, p=0.009) and AST levels, demonstrating hepatoprotective effects. Larger reductions were observed in patients with higher baseline enzyme elevations.”Voroneanu et al., Complementary Therapies in Medicine, 2018

“Double-blind, placebo-controlled RCT of 36 patients with non-alcoholic fatty liver disease. Silymarin (700 mg/day) for 8 weeks significantly reduced hepatic steatosis on ultrasound, lowered ALT and AST (p<0.05), and decreased insulin resistance (HOMA-IR) versus placebo, supporting silymarin's role in liver enzyme normalization.”Hashemi et al., Journal of Hepatology, 2009
