Our Verdict
Ultima Replenisher stands out as the cleanest formulation in the mainstream electrolyte category: citrate-form minerals across the board (magnesium citrate, calcium citrate, zinc citrate), no fillers, no artificial anything, zero sugar/calories, and plant-based colors. The 6-electrolyte plus trace mineral profile is impressive. The main limitation is very low sodium (55mg) -- fine for daily hydration but insufficient for heavy exercise or sweat loss. At $0.50/serving it's excellent value for the ingredient quality.
