Milk thistle supplements come as seed powder, extracts, and blends with other ingredients; comparing them starts with what the label says each serving contains. Extracts and seed powders are different preparations, so a larger amount of either does not necessarily mean more silymarin. Start by deciding whether you want milk thistle by itself or a formula that adds other supplements.
For a milk thistle product on its own, read the supplement facts panel for the preparation used and the amount per serving. For a blend, look for separately stated amounts so you can tell how much milk thistle accompanies the other ingredients. Some extracts state a standardized silymarin content, which identifies the proportion or amount of silymarin. Extract weight describes the amount of extract, while a seed-equivalent quantity describes how much starting seed it represents; neither is itself a measure of silymarin content. Among the 30 products that list item weight, most fall between 0 and 0.5 pounds, and 0.2 pounds is typical. Package weight cannot tell you the amount of milk thistle or silymarin in a serving, so compare the ingredient declarations instead of bottle weight.
Next, compare the label’s serving directions with the routine you can follow: how much constitutes a serving, how often it is taken, and whether the directions specify food. A bottle’s capsule count is not necessarily its serving count. The item form filter lists Capsule and Capsules; the dosage form filter lists Capsule and Liquid. Neither filter tells you the serving instructions or full formulation. Use the full ingredient list to assess capsule shell ingredients, sweeteners, alcohol, or other ingredients against your dietary restrictions. For a liquid preparation, establish how the labeled serving is measured and whether the required measuring device is supplied or sold separately.
Before buying, read the intended-user information and warnings, including any restrictions concerning age, pregnancy, breastfeeding, allergies, or use alongside medicines. Do not assume that a blend has the same warnings as a milk thistle product with no additional active ingredients. For storage, the label should specify any refrigeration or other requirements after opening, particularly for liquids. If the label gives a use-after-opening period, check whether you can finish the bottle within it at the labeled serving frequency.
