Waterex
GNC Pro Performance AMP Waterex is a botanical and nutrient blend designed for fluid balance support. Each capsule provides 25mg of Vitamin B6, which is at a clinically studied dose. However, both Magnesium (25mg) and Potassium (25mg) are considered underdosed for their potential roles in electrolyte balance. The product also includes a 50mg Proprietary Blend, which lacks transparency regarding its specific botanical components and their dosages. With an N+ Score of 55 and an F grade, it falls into the average quality tier. While it offers a clinical dose of Vitamin B6, the underdosed minerals and proprietary blend limit its overall evidence-based appeal. It may be suitable for individuals seeking a basic fluid balance formula with some vitamin support.
