Why it matters
A real physiological role with a real research history
Human exercise research has studied sodium bicarbonate as a nutritional buffering strategy, including controlled work in high-intensity exercise. That makes bicarbonate a meaningful performance-research ingredient rather than a decorative electrolyte.
Best Hydrate includes sodium bicarbonate as a purposeful part of its electrolyte architecture, contributing sodium + bicarbonate alongside its low-sugar, purposeful-glucose core.
