A TrailGenic Mount Baldy review of Re-Lyte, documenting subjective hydration, tolerance, intake, and its role relative to other electrolyte options.
TrailGenic classification: electrolyte field option. Re-Lyte was tested during a fasted Register Ridge–Mount Baldy effort and compared with Mike’s prior experiences using LMNT, ATH Lytes, and Nuun.
Mike reported less mouth dryness than during the Nuun comparison, loose calves, acceptable taste, and no notable GI distress. He also consumed more than one serving and felt that focus and drive declined before the summit.
A zero-calorie electrolyte does not provide energy, so an energy decline cannot be assigned to sodium concentration alone. Pace, glycogen availability, sleep, accumulated fatigue, weather, altitude response, caffeine, and expectation may all contribute. The result supports a personal preference; it does not prove that Re-Lyte is physiologically underpowered.
Formulas and serving sizes change. Verify current sodium, potassium, magnesium, sweetener, and scoop information. Compare products per mixed liter and per hour—not simply packet versus packet.
Re-Lyte performed acceptably and remains part of the field archive. Mike preferred LMNT for his hardest summit efforts, but that conclusion is personal and contextual.
