Raw Nutrition | Replenish | 60 Servings

Raw Nutrition Replenish is a purpose-built electrolyte hydration formula, not a disguised pre-workout and not a sugar-heavy sports drink pretending to solve serious sweat loss. The formulation strategy is straightforward and effective: replace the minerals most heavily involved in fluid retention, extracellular balance, muscle contraction, and nerve transmission, with a clear emphasis on sodium-first hydration. That matters because for athletes who sweat heavily, sodium loss is usually the main limiter to effective rehydration. Plain water can dilute plasma sodium and still leave you feeling flat, cramp-prone, and under-recovered. Replenish is designed to correct that.

The formula’s anchor is 1,000mg sodium per serving. In hydration terms, that is a meaningful dose. It sits in the range serious athletes look for when replacing sweat losses, especially during long sessions, hot environments, or two-a-day training. Sodium is the primary extracellular electrolyte; it helps maintain plasma volume, supports nerve impulse conduction, and drives fluid retention. This is the mineral that makes the water you drink actually stay useful in the body rather than passing through too quickly. The inclusion of chloride at 1,200mg reinforces that effect, because sodium and chloride work together to regulate osmotic balance and extracellular fluid volume.

Chloride is often ignored on labels, but it is not filler. It is an essential electrolyte involved in fluid regulation and acid-base balance, and it naturally pairs with sodium in hydration physiology. In practical terms, the sodium-chloride backbone of this formula is what gives it real-world utility for performance, not just label decoration.

Magnesium is included at 50mg. That is not a full standalone magnesium correction dose, but it is a useful support level inside a hydration formula. Magnesium contributes to neuromuscular function, muscle relaxation, and electrolyte balance, and it acts as a cofactor in hundreds of enzymatic reactions. For an athlete, that means better support for normal muscle firing and less of the “tight, twitchy, depleted” feeling that can accompany hard sweating. This dose is supportive rather than aggressive.

Potassium is listed here at 50mg in the verified formula. That is below the levels typically used when potassium is a headline ingredient, but it still plays a physiological role. Potassium is the primary intracellular electrolyte and works with sodium through the Na+/K+-ATPase system to maintain cellular electrochemical gradients. That is foundational for muscle contraction and nerve signaling. The dose is modest, so this product should be viewed as sodium-led hydration first, not as a high-potassium electrolyte formula.

Calcium is present only in a trace amount and is not a meaningful driver of the formula’s effects.

The synergy is clear: sodium and chloride restore extracellular hydration, potassium supports intracellular electrolyte balance, and magnesium helps the neuromuscular system use that hydration more effectively. This is a fully disclosed label with no proprietary blend, which is a major positive in a category full of vague hydration mixes. You can see exactly what you are getting.

What should you expect? Day 1, the biggest difference is practical: better thirst satisfaction, better fluid retention, less washed-out feeling during or after hard sweating, and a stronger sense of staying “on” physically as sessions run long. Over 2-4 weeks of consistent use, especially if you are someone who regularly under-replaces sweat sodium, the payoff is better training consistency, fewer hydration-related dips, and more stable performance across hot days, long sessions, and repeated workouts.
