Common Uses -
Protects the liver from toxins, including drugs, poisons, and chemicals.

To be sure you're getting the proper dose, buy products made from standardized extracts that contain 70% to 80% silymarin, the active ingredient in milk thistle. You may also want preparations that contain milk thistle bound to phosphatidylcholine, a principal constituent of the natural fatty compound lecithin; studies show this combination may be better absorbed than regular milk thistle.
Be wary of alcohol-based tinctures. Some formulas contain high amounts of alcohol, which can be bad for the liver if taken in large doses.
Milk thistle seems most effective when taken between meals. Its benefits may be noticeable within a week or two, though long-term treatment is often needed for chronic conditions.
The herb appears to be safe, even for pregnant and lactating women. No interactions with other medications have been noted.
Dosage: The recommended dose for milk thistle is up to 250 mg of standardized extract (containing 70% to 80% silymarin) three times a day. It is often combined with other herbs and nutrients, such as dandelion, choline, methionine, and inositol. This combination may be labeled "liver complex" or "lipotropic factors" ("lipotropic" refers to the formula's fat-metabolizing properties; it prevents the buildup of fatty substances in the liver). For proper dosage, follow package directions.
