ELECTROLYTES REPORT

Labdoor analyzed 6 of the best-selling electrolyte supplements in the United States. Analytics tests were performed on electrolyte content (sodium, potassium, magnesium) and heavy metal contamination (arsenic, cadmium, lead, mercury).

Research supports supplementing with sodium, and in extreme cases, potassium, for exercise lasting longer than 90 minutes andor exercise in extreme heat if you're not used to those conditions1,2,3. In these situations, they've been shown to help with signs of dehydration and electrolyte imbalance like dizziness, nausea, and muscle spasms4,5.

Four of the six products tested met their label claims for sodium content, and only one product missed it’s label claim for potassium content. However, only one product that claimed magnesium met it’s label claim. Across the electrolytes tested we found that the average product tested contained 18.1% more electrolytes than claimed. All products tested well below USP limits for heavy metals (arsenic, cadmium, lead, mercury).
