Highest sodium per serving

For heavy sweating, heat, and low-carbohydrate diets.

  1. LMNT Zero Sugar Electrolytes, Raw Unflavoured — 1000 mg per 16 fl oz (475 ml)
  2. Redmond Re-Lyte Hydration — 810 mg per 16–20 fl oz (475–590 ml)
  3. Pedialyte AdvancedCare Plus Powder — 650 mg per 16 fl oz (475 ml)

Before choosing on this basis, read how much sodium you actually need — more is not better, it is just different.

Highest potassium per serving

Potassium intake falls short of recommendations far more commonly than sodium does.

  1. Redmond Re-Lyte Hydration — 400 mg per 16–20 fl oz (475–590 ml)
  2. Pedialyte AdvancedCare Plus Powder — 370 mg per 16 fl oz (475 ml)
  3. Liquid I.V. Hydration Multiplier — 370 mg per 16 fl oz (475 ml)

Highest magnesium per serving

  1. Ultima Replenisher — 100 mg
  2. LMNT Zero Sugar Electrolytes, Raw Unflavoured — 60 mg
  3. Redmond Re-Lyte Hydration — 50 mg

Zero sugar

Suitable for daily use, low-carbohydrate diets, and anyone counting intake.

Third-party tested

Independent batch-testing certification is rare in this category. 1 product carries one:

NSF Certified for Sport is the strictest of the three programmes; Informed Choice audits ingredients and spot-checks batches. Nuun's separate Podium line (Endurance, Prime, Recover) carries Informed Sport rather than Informed Choice. If you are subject to anti-doping testing, confirm the certification covers the exact product you are buying rather than the brand — certifying one line and letting the halo spread across the range is common.
