Ingredients

The same plant, from two manufacturers, can differ in potency by an order of magnitude — and both labels can be honest. This section is about the details that decide which is which.

“Contains turmeric” is not a specification. It is a category. The turmeric in one bottle might be ground root; in another, an extract standardized to 95% curcuminoids — roughly twenty times the concentration of the active compounds, from the same plant, under the same word on the front of the label.

This is where most side-by-side comparisons quietly fall apart. Buyers compare the ingredient lists, find them identical, and conclude the cheaper product is the better deal. Sometimes it is. Often the two products are not comparable at all, and the label gave no obvious sign of it — because the information that would have told you sits in the parts most people skim: the extraction ratio, the standardization percentage, the plant part used, and whether anybody independent ever opened the bottle to check that what is claimed is what is inside.

That last one matters more than it gets credit for. “Lab tested” means nothing — every manufacturer tests in a lab. Third-party certified means something specific, verifiable, and lookup-able in a public database. Knowing which is which takes about five minutes, once.

Standardized Extracts: What the Percentage Means

Why “standardized to 95%” matters, and why a 10:1 ratio on its own tells you almost nothing.

Third-Party Testing: What It Verifies and What It Does Not

USP, NSF and the rest confirm what is in the bottle. None of them confirm that it works.
