How to take Milk Thistle Seed

What makes Milk Thistle Seed work

Milk Thistle Seed contains silymarin — a powerful antioxidant complex shown in studies to protect and support the liver. It's been used for over 2,000 years to help the liver recover from rich food, alcohol, and toxins.

Decoction

Simmer 1 tablespoon of the dried root or bark in 2 cups of water for 20–30 minutes (lid mostly on). Strain and sip. Decoctions are for hard plant parts that won't give up their actives to a quick steep.

Capsule

Swallow 1–2 capsules (typically 300–600 mg) with water, 1–2 times a day. The easiest form if you don't like the taste.

Dosage

Capsule (standardized): 200-400mg silymarin daily; Ground seed: 1 tsp in food/tea 2-3x daily
