A supplement label can say a lot without telling you much. Here’s what I look for underneath it, so you can see whether a product is a real, measured extract or just a plant name and a big number on the front.
As a plant biologist and environmental scientist, I was trained in plant biochemistry and in how compounds are measured and verified. That is the part of a supplement most brands gloss over. I read the label for the species, the plant part, the type of extract, and what a claim like “standardised to a set percentage” actually means, because that is where the difference between a serious product and a weak one usually hides.
Before any brand goes below, I check its claims against reliable scientific sources rather than trusting the packaging. Each one that made the list did so because its label holds up to that reading, and I note the catch worth knowing before you spend anything.
Here is what I would look at first.
