Frequently asked questions
How much sodium do I actually need in an electrolyte drink?
It depends on the job. Light daily use can be 55–300 mg per serving; heavy sweating in heat can justify 500–1,000 mg or more. Our comparison spans 55 mg to 1,500 mg per serving — match the dose to the loss, not to the loudest label.
Is more magnesium always better?
No, but 0 mg is worth noticing — the best-known brand's hero formula lists none. Look at the form as well as the amount: glycinate and malate are gentler and better used than oxide. See our label guide.
Are sugar-free electrolytes better?
For daily use, most people prefer to skip 11 g of sugar per glass. For illness and long endurance work, some sugar is functional — glucose helps sodium absorption, which is why oral rehydration formulas include it.
What is the cheapest way to drink electrolytes daily?
Bulk formats. A 90-serving tub at $0.47–$0.53 per serving costs a third of a premium stick habit. The budget list compares tubs, pouches and workplace bulk.
Can I give adult electrolytes to my child?
Check the age guidance on the pack — some products in big family brands are positioned for adults only. Our kids guide separates illness formulas from everyday kids' drinks, which have very different doses.
Why do you date your prices?
Because they are label figures checked in Oct 2026, not live prices. Retailers change prices constantly; each brand profile links to a current-price check.
