  1. Saltivate

    Best for heavy sweaters and value

    800mg sodium · 240mg potassium · 60mg magnesium · From $0.41/serving

    The high-sodium pick that skips the compromises. 800mg sodium with real potassium and magnesium, no stevia, no sugar, and no sugar alcohols, so it will not bloat you. The potassium is potassium citrate, which is close to tasteless, instead of the bitter potassium chloride most brands use. It is also the only powder here you can pay for directly with an HSA or FSA card at checkout, no doctor's letter required.

  2. LMNT

    Best for salt purists who like stevia

    1,000mg sodium · 200mg potassium · 60mg magnesium · $1.50/serving

    The category benchmark and the highest sodium on this list. If you want maximum salt and do not mind stevia, it delivers. The trade-offs are a premium price near $1.50 a stick, a stevia finish some people dislike, and no direct HSA or FSA card payment.

  3. Redmond Re-Lyte

    Best for budget high-sodium

    810mg sodium · 400mg potassium · 50mg magnesium · $0.77/serving

    Strong mineral spread and one of the better prices per serving in the high-sodium tier. It is stevia sweetened and uses potassium chloride, which adds a salty, slightly bitter edge, so taste is the main reason to look elsewhere.

  4. SALTT

    Best for the biggest magnesium dose

    968mg sodium · 408mg potassium · 178mg magnesium · $1.20/serving

    Loads every mineral, with by far the most magnesium here at 178mg. That makes it a fit if magnesium is your priority, but it is stevia sweetened and priced at the top of the range.

  5. NormaLyte

    Best for medical-grade rehydration

    851mg sodium · 393mg potassium · 0mg magnesium · $1.33/serving

    A pharmacist-formulated oral rehydration mix aimed at POTS and dysautonomia, and it is HSA or FSA eligible. The catches are sucralose as the sweetener and no magnesium in the formula.

How we ranked these

Our method and sources

Every mineral value is taken from each brand's published Nutrition or Supplement Facts panel. Prices are per serving at each brand's full MSRP, using the best-value size, never a sale price. Price per serving for Saltivate reflects the 90-serving unflavored jar. Sodium needs reference sweat-sodium research, roughly 0.5 to 1.5 grams of sodium lost per liter of sweat, so heavy and salty sweaters sit at the high end. For endurance efforts longer than a few hours, higher-sodium options such as Precision PH 1500 exist but sit well above this price range. Last updated July 2026.

High-sodium electrolytes: FAQ

What is the best high-sodium electrolyte powder for heavy sweaters?
For most heavy and salty sweaters, Saltivate is the best balance: 800mg sodium with 240mg potassium and 60mg magnesium, no sugar, no stevia, and no sugar alcohols. It costs from $0.41 a serving and is the only powder in this guide you can buy directly with an HSA or FSA card. If you want the absolute highest sodium and do not mind stevia, LMNT has 1,000mg.

Which electrolyte powder has the most sodium?
Among the popular high-sodium powders, LMNT leads at 1,000mg, followed by SALTT at 968mg, NormaLyte at 851mg, Re-Lyte at 810mg, and Saltivate at 800mg. More is not automatically better: match your sodium to how much you actually sweat. For very long endurance efforts, specialist mixes like Precision PH 1500 go higher still.

Are there high-sodium electrolytes without stevia or artificial sweeteners?
Yes. Most high-sodium powders use stevia or sucralose, but Saltivate does not. Its flavored mixes use Reb M and its unflavored mix has no sweetener at all. It also contains no sugar alcohols, which are the usual cause of bloating from zero-sugar electrolyte powders.

Which high-sodium electrolyte powders can I buy with an HSA or FSA card?
Saltivate and NormaLyte take an HSA or FSA card directly at checkout with no Letter of Medical Necessity. Many others, including LMNT, only qualify through a telehealth letter routed via a third party. Pay directly whenever you can so your benefits card does the work at checkout.

What should I look for if I get salt stains on my workout clothes?
White salt rings on your clothes mean you are a salty sweater and losing a lot of sodium. Look for at least 800mg of sodium per serving, minimal or no sugar, and a sweetener you tolerate. A high-sodium powder like Saltivate replaces what the salt stains show you are losing.
