Vitamins
Hair, skin & nails formulas
Mixes built around biotin, often with collagen and other vitamins. Hair, skin and nails need these nutrients to grow – extra helps only if you lack them.

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 161 products score
- Very good 90+: 1
- Good 75+: 118
- Fair 60+: 29
- Low under 60: 13
13 products contain titanium dioxide and Red No. 3 – 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
- 99%have no seal from an independent testing program10 of 30 testing points for GMP, 15 for the 5 whose label says “third-party tested”
- hide amounts in a “proprietary blend”
- 23%hide amounts in a “proprietary blend”5 of 20 transparency points – you only see the total
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
