The details

Cross-referenced with PubMed & Examine.com

✓No flagged ingredients detected
Maltodextrin + Fructose37g carbs
✓ Proven

Glucose-based carbs plus fructose use two separate gut transporters, allowing intakes up to ~90g/hr with less stomach upset than a single sugar.

Sodium350mg
✓ Proven

Sodium is the main electrolyte lost in sweat; replacing it supports fluid balance in long or hot sessions.

Potassium88mg
~ Likely

An electrolyte involved in muscle and nerve function; sweat losses are much smaller than sodium's.

Magnesium5mg

Calcium25mg
~ Likely

An electrolyte and bone mineral; sweat losses are small compared with sodium.

Chloride530mg
~ Likely

Chloride is lost in sweat along with sodium, and is usually replaced along with it, as sodium chloride.
