-
"Provides healthy hydration and mineral replenishment"
Electrolyte doses (sodium 100mg, potassium 150mg) are appropriate for exercise hydration support.
PubMed: electrolyte research for sports hydration -
"Blend of vitamins, minerals & electrolytes for optimal hydration"
Vitamin doses are 10-34% DV per tablet—far below therapeutic levels. You're mostly paying for electrolytes.
Internal: dose comparison vs. PubMed clinical ranges -
"Vitamin supplementation included"
Vitamin C 10mg, B6 0.25mg, D 5mcg—all token doses. Therapeutic ranges are 200-2000mg, 50-100mg, 400-2000 IU respectively.
Consumer advice
If you need electrolytes for exercise, Nuun Vitamins is a reasonable choice—it tastes good and dissolves easily. However, don't buy it expecting meaningful vitamin supplementation. The vitamin doses (10 mg vitamin C, 0.25 mg B6, 5 mcg vitamin D) are far below therapeutic levels. If you want both hydration AND vitamins, buy a cheap multivitamin separately (~$5-10/month) and use regular Nuun Sport or Liquid IV for electrolytes (~$0.50-1.00/serving). You'll save money and get actual vitamin doses that matter."
