When considering best milk thistle capsules in India it’s worth noting the silymarin content. That’s because silymarin and milk thistle extract are not the same thing. Milk thistle is the plant source, whereas silymarin is a group of chemicals derived from the plant. Two capsules may have the same quantity of milk thistle extract, but different amounts of standardised silymarin. So looking at the whole supplement facts panel gives you more meaningful information than just comparing the overall extract weight.
