Minerals & electrolytes
Electrolytes
Salts like sodium, potassium and magnesium as powder, tablets or drops. They replace what you lose in sweat. We compare them by sodium.
271 products from US online stores, sorted by what 500 mg of sodium costs – not by the price per pack.

What does 500 mg mean?
- sodium per serving in most of the products we checked
- 55–520 mgsodium per serving in most of the products we checked
- sodium a day: adequate intake for adults (National Academies)
- 1,500 mgsodium a day: adequate intake for adults (National Academies)
- sodium a day: adults should stay below this (Dietary Guidelines)
- 2,300 mgsodium a day: adults should stay below this (Dietary Guidelines)
- 500 mg is a fixed amount to compare by: half of the 271 products we checked have up to 190 mg per serving, the other half more.
- 500 mg is less than the 1,500 mg of sodium a day that’s considered adequate for adults, from food and drinks together (National Academies (opens in a new tab)).
We compare by 500 mg 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 271 products score
- Very good 90+: 36
- Good 75+: 225
- Fair 60+: 5
- Low under 60: 2
- No score, label not readable: 3
2 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
- 86%have no seal from an independent testing program10 of 30 testing points for GMP, 15 for the 26 whose label says “third-party tested”
- contain artificial sweeteners
- 16%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: Electrolytes: what you pay for 500 mg of sodium
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.
