What does 1 mg mean?
- melatonin per serving in most of the products we checked
- 1–12 mgmelatonin per serving in most of the products we checked
- 1 mg is a fixed amount to compare by: half of the 326 products we checked have up to 5 mg per serving, the other half more.
- There’s no official daily amount for melatonin.
We compare by 1 mg only so products line up – it’s not a recommendation. Not medical advice.
Where products miss quality points
How the 326 products score
- Very good 90+: 7
- Good 75+: 311
- Fair 60+: 5
- Low under 60: 3
3 products contain titanium dioxide – a food authority has banned, restricted or flagged it 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
- 98%have no seal from an independent testing program10 of 30 testing points for GMP, 15 for the 32 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

How we checked: one-time price for each size in the store’s US online shop, before sales tax and shipping, without subscriptions or coupons. Prices change often, so check the store before you buy. More on how we check
The amount we compare by only makes products comparable – it is not a dosage recommendation. Not medical advice.
How we calculate
Cost per dose = price ÷ (servings × amount per serving) × comparison amount. Example: $119.99 for 74 servings with 24 g of protein each is 1,776 g of protein. $119.99 ÷ 1,776 g × 30 g = $2.03 per 30 g of protein.
