This is a hydration powder built around electrolytes and a handful of extras. You're getting **Sodium** (210mg), **Potassium** (160mg), **Calcium** (160mg from calcium citrate), and **Magnesium** (63mg from magnesium citrate) — a solid electrolyte base for daily hydration or light exercise, though athletes sweating heavily may need more. The calcium and magnesium use citrate forms, which absorb well without needing food.

**L-Glutamine** at 1,425mg is the largest active ingredient by weight, but clinical research on gut barrier support and recovery uses 5–15g per day — so you're getting roughly a quarter of the minimum studied dose. **Acetyl-L-Carnitine** at 375mg falls just short of the 500mg clinical minimum for energy and cognitive support, and the B vitamins are all near basic dietary levels rather than therapeutic doses — **B12** at 0.5mcg is actually below the 2.4mcg RDA, in a synthetic form that requires conversion.

The "all-in-one" label sets broad expectations, but the vitamins, minerals, and amino acids are dosed too low to deliver meaningful standalone benefits beyond basic hydration. If you're buying this for electrolyte replenishment, it delivers. If you're expecting the glutamine, carnitine, or B vitamins to move the needle on recovery or energy, you'd need to supplement those separately at higher doses.

Other ingredients

SucraloseSweetener

Dose context matters. As a trace excipient in a tablet coating or capsule, the amount is minimal and not a meaningful concern. The evidence below applies to the gram-level intakes typical of sweetened protein powders, pre-workouts, and drink mixes: a 2022 human trial (Suez et al., Cell) showed sucralose disrupts gut bacteria and worsens blood sugar control in healthy adults, and a 2023 study (Schiffman et al.) found that sucralose-6-acetate — a compound formed when sucralose is digested — was genotoxic to human cells in vitro. It remains an artificial sweetener with no nutritional purpose.

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Natural Color (unspecified)Colorant

Umbrella declaration for a colorant from a natural source (fruit, vegetable, or plant extract) that the label does not name specifically

Natural FlavorsFlavor

Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.
