What does 30 g mean?
- protein per serving in most of the products we checked
- 18–26 gprotein per serving in most of the products we checked
- protein per serving for people who exercise (ISSN)
- 20–40 gprotein per serving for people who exercise (ISSN)
- protein per kg of body weight a day, for people who exercise (ISSN)
- 1.4–2.0 gprotein per kg of body weight a day, for people who exercise (ISSN)
- 30 g is about one serving: half of the 803 products we checked have up to 23 g per serving, the other half more.
- There’s no single daily amount for protein – it depends on body weight: 1.4–2.0 g per kg a day for people who exercise, from food and supplements together (ISSN (opens in a new tab)).
We compare by 30 g only so products line up – it’s not a recommendation. Not medical advice. More on amounts, with sources
Where products miss quality points
How the 803 products score
- Very good 90+: 150
- Good 75+: 556
- Fair 60+: 64
- Low under 60: 20
- No score, label not readable: 13
10 products contain artificial colors with an EU warning, 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
- 79%have no seal from an independent testing program10 of 30 testing points for GMP, 15 for the 86 whose label says “third-party tested”
- contain artificial sweeteners
- 20%contain artificial sweetenerscosts 2 of the 20 additive points
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

What’s that?
An independent lab (NSF) checks that the label matches what’s inside and tests for 290 substances banned in sport. Source (opens in a new tab)
Guide: Protein powder: the cheaper tub isn’t always the cheaper protein
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.
