FASTCHEWS features a scientifically-derived, proprietary high-performance formulation that provides a balanced supply of bioavailable sodium, potassium, magnesium, and calcium. Sodium is derived from sodium citrate, a proven source that has the added benefit of soothing the stomach. The formulation mirrors the electrolyte profile lost in sweat, in a form and quantity the body can absorb. Its non-GMO ingredients are all natural, gluten-free, vegetarian, and without artificial sweeteners or colours. Rapid absorption takes place by mouth (buccal mucosa, and then the stomach). Ease of access is assured in a convenient moisture-resistant roll-wrapped format. This "Green" product generates little trash.
