Low-sodium electrolyte drinks, ranked by potassium
The best low-sodium electrolyte drinks meet the FDA low-sodium rule, 140 mg or less per reference amount [9], and carry the most potassium per liter. Once sodium is off the table, potassium is the main electrolyte left to compare, so it is the whole score. Ties go to the lower cost per liter.
On current label data the top three are Harmless Harvest Organic Coconut Water, Zipfizz Energy Drink Mix and Vita Coco Original Coconut Water.

How we ranked
Any format qualifies if its sodium, scaled to the FDA reference amount of 360 mL [10], is above 0 mg and no more than 140 mg, and the label lists potassium. The score is potassium per liter as mixed.
- Who qualifies
- Any format with no more than 140 mg sodium per 360 mL (the FDA low-sodium rule). The label must list calories, carbohydrate, sugars, sodium (above 0 mg) and potassium. We do not rank a product whose panel we could not read in full.
- How the score works
- Score is potassium per liter as mixed, in mg. Higher ranks first. Ties go to the product whose label lists more nutrients, then to the lower cost per liter.
Scores use label data and published reference values only. Affiliate links and commission play no part. Read the full methodology.
What to look for in a low-sodium electrolyte drink
Know what you are giving up. Low-sodium drinks carry less sodium than even the least salty sweat, which starts around 230 mg/L [1]. They replace little of the sodium lost in a long, sweaty session.
Potassium. Several drinks here carry far more potassium than sweat does. Sweat averages about 196 mg/L [6]. The potassium column in the table shows each one per liter.
Sugar. Some low-sodium drinks are coconut-water based or sugar sweetened. The sugar column shows grams per 12 fl oz.
Few products qualify. Most electrolyte drinks are built around sodium, so this list is short. It includes every product we track that passes.
FAQ
What is a low-sodium electrolyte drink?
On a US label, “low sodium” means 140 mg or less of sodium per reference amount [9]. For drinks that is 360 mL, close to 12 fl oz [10]. The drinks above all meet that rule and are ranked by potassium, the main electrolyte they carry.
Which electrolyte drink has the most potassium?
Among low-sodium drinks, the one at the top of this list. Across all drinks we track, some higher-sodium products also carry a lot of potassium. Each product page in the drinks database shows potassium per liter if sodium is not a concern for you.
Are low-sodium electrolyte drinks enough for exercise?
For short or easy sessions, fluid and normal meals usually cover sweat losses [6]. For long, hot or very sweaty sessions, these drinks replace little of the sodium you lose, since they carry less sodium than typical sweat [1]. The sodium per hour guide explains the numbers.
Are there low-sodium electrolyte drinks with no sugar?
Yes, a few. Check the sugar column in the table, which shows grams per 12 fl oz for every drink. Some low-sodium drinks use stevia, allulose or sucralose instead of sugar, and some use coconut water. The notes under each product show the sweeteners the label lists.
