In summary, there is currently no regulation of supplements in the US. This means that if you buy a supplement like Resveratrol and the label clearly states that it is from Japanese knotweed, it should contain that ingredient. However, if the label also claims that the supplement is "standardized," this may not necessarily guarantee the amount of the active ingredient in each pill or drop. It is important to be cautious when purchasing supplements and to be aware that the amount of the active ingredient may vary.

In US there is no regulation of supplements. So if I buy Resveratrol, and the manufactorer and label clearly state "Resveratrol from japanese knotweed" does it have to contain it and not containing it violate some kind of law?

That's a good question.

If the label says "standardized" it means that the contents have extracts in the amount stated on the label. There are companies that self-regulate and actually take legal action against other companies who just pump out pills - when they attempt to put standardized on the label. The downside to this is that the standardized extracts say things like 10X which means the ingredient in question has been concentrated by a factor of 10, it may not guarantee 10mg in each pill, or each drop of liquid.

Many vitamin and supplement pills contain varying amounts of the active ingredient.
Caveat emptor.

To answer your question, it must contain at least some japanese knotweed extract if the label indicates it. Who knows how much?
