Milk Thistle Supplements

Milk thistle supplements contain extracts from the plant Silybum marianum and are commonly sold as capsules, tablets, powders, drops and liquid extracts. The principal extract is usually described as silymarin, which is a mixture of plant compounds, although the stated amount and concentration differ considerably between products. Compare the milk thistle extract and silymarin amount per serving, the number of daily servings and any additional herbs. High-quality evidence remains insufficient to confirm definite health benefits, and products may cause digestive discomfort or allergic reactions, particularly in people sensitive to ragweed-related plants. Medicine users and pregnant or breastfeeding customers should seek professional advice before use.
