Milk Thistle

Milk thistle (Silybum marianum) is the best-known herb for liver support. Its seeds contain silymarin, a group of antioxidant flavonolignans that support healthy liver function and the liver's natural detoxification processes.

This collection includes milk thistle and silymarin capsules, tablets, phytosomes and liquid extracts from Pure Encapsulations, Integrative Therapeutics, NutriDyn, Herb Pharm, Natural Factors and more.

How to Choose a Milk Thistle Supplement

• Standardized extracts: Look for extracts standardized to silymarin, often around 80%, so you know how much of the active compounds you get.
• Phytosome forms: Milk thistle bound to phosphatidylcholine is designed for better absorption.
• Liquid extracts: Herbal tinctures that are easy to add to water.
• Liver blends: Milk thistle combined with NAC, dandelion, artichoke or other liver-supporting nutrients.

Milk thistle is often taken alongside NAC and glutathione. Explore more in liver support and detoxification.
