Why per serving?
These products don’t share one ingredient amount we could compare by – many are mixes, others list units like FCC. So we compare the price of one serving as the label defines it. A serving can be 1 tablet or 4 capsules and hold more or less – check the label before you buy.

Where products miss quality points
How the 293 products score
- Very good 90+: 14
- Good 75+: 245
- Fair 60+: 26
- Low under 60: 8
8 products contain titanium dioxide and artificial colors with an EU warning – a food authority has banned, restricted or flagged them as a possible health risk. Their score is cut in half, so it’s always in the red range. Each product says why.
- have no seal from an independent testing program
- 95%have no seal from an independent testing program10 of 30 testing points for GMP, 15 for the 22 whose label says “third-party tested”
The full 30 testing points need an independent test. Every supplement sold in the US is made under the FDA’s GMP rules – the maker checks its own products, which gives 10 points. A seal from a testing program like NSF, USP or Informed Choice means a lab outside the company checks that what’s inside matches the label. Most brands don’t take part. That doesn’t make a product bad – without a seal, a clean product still gets up to 80.
We find seals on the label and in NSF’s public lists. USP and Informed Choice don’t let us search their lists automatically, so a seal that’s only in their lists can be missing. How the score works

The amount we compare by only makes products comparable – it is not a dosage recommendation. Not medical advice.
How we calculate
Cost per serving = price ÷ servings in the pack, with the serving as the label defines it.
