Dandelion Root Extract

Reviewed by the Nimbera editorial team · Last updated May 2026

An animal study (Pfingstgraf et al., Antioxidants, 2021) found dandelion root extract at 100 mg/kg significantly reduced serum liver injury markers (AST, ALT, ALP, GGT, total bilirubin) and oxidative stress in a rat model of acute-on-chronic liver failure, outperforming silymarin at some doses. No large human RCTs have been conducted.$8-$20 per month

How to use

Take 500-2000 mg of dried dandelion root extract in capsule form daily, or brew 1-2 teaspoons of dried root as tea steeped for 10-15 minutes, up to 3 times per day. Standardised extracts offer more predictable dosing than loose root. Use for 4-8 weeks as a support measure.

How it works

Dandelion root contains polyphenolic compounds including caffeic acid, chicoric acid, and luteolin that act as antioxidants, reducing oxidative stress in liver tissue. These compounds may also support bile production and flow, aiding fat digestion and liver drainage.

Where to buy

Traditional Medicinals Dandelion Root Tea (Whole Foods, Target), Solaray Dandelion Root (iHerb, Amazon), Nature's Answer Dandelion Root (Vitacost). Widely available at health food stores.

Typical cost: $8-$20 per month
