How much sodium do you need in an electrolyte drink?

Across the products in our database, declared sodium per serving spans from small everyday amounts to well over a gram. That spread is not a quality difference; it reflects who the mix was formulated for. Everyday drinking mixes sit low, sport mixes sit in the middle, and heat and long-effort mixes sit high.

Because the figure is a formulation decision rather than a standard, the only way to compare products honestly is per serving, using the number the brand declares on its own label. We do not estimate sodium for products that do not declare it — those show as not declared rather than as zero.

Sweat losses vary with how long and how hard you work, the temperature and humidity, your clothing, your acclimatisation and how salty your own sweat is. Two people in the same session can lose noticeably different amounts.

This is general information about product labelling, not medical or dietary advice. If you have a health condition, take medication, or want a personal sodium target, ask a qualified health professional rather than a comparison site.

Every product page shows the declared sodium per serving alongside the serving size it applies to, plus potassium, magnesium, calcium and chloride where the label declares them. Tablets are declared per tablet, which is typically a smaller number than a powder serving — compare per serving, never per tube or per tub.

The database view lets you sort and filter on the declared figure directly, and the category pages pre-apply the common thresholds.
