Bare Hydrating Aminos contains the same EAA formula as our Bare Aminos, with added 4 electrolytes to support hydration: Sodium, Potassium, Calcium & Magnesium. By combining our powerful Essential Amino Acid (EAA) blend with a unique electrolyte mix, we've created a product that not only supports muscle repair and growth but also ensures optimal hydration and sustained energy.
Whether you're 35km into Comrades or 12 minutes into a hero WOD, your body is losing what it needs to keep going. Hydrating Aminos replaces both — at once.
Long sessions and hard sessions both break the same things — muscle, fluid balance, electrolytes, energy. Hydrating Aminos handles all four in parallel.

Sweat sodium losses, ACSM 2007For sessions over 90 minutes, when whole food is impractical and water alone causes hyponatraemia. Designed for the second half of long efforts.
For Comrades, Two Oceans, Ironman, century ridesFor Hyrox stations, CF metcons, double sessions, and hot-day training. High intensity drains electrolytes faster than duration alone.
For Hyrox, CrossFit, padel, hot-climate gym workHydrating Aminos isn't 'EAAs with electrolytes added' — it's two evidence-led protocols engineered to support each other. Read the science behind both.
10 conclusions, the dose-response curve, free-form vs whey absorption. With our interactive calculator.
Read the EAA science →Why sodium matters more than water for sessions over 60 minutes — and why pairing it with EAAs outperforms either alone.
Read the hydration science →Pure electrolytes don't build muscle. Pure EAAs don't replace sweat losses. Whey is too slow for intra-workout. We saw the gap and engineered for it.

Both have the same EAA blend. Hydrating Aminos adds electrolytes for sessions where sweat and intensity matter. Pick the one that fits how you actually train.
Hydrating Aminos earns its place when the session asks more of you — through duration, heat, intensity, or all three at once.
1–2 scoops per session. Mix into 500–750 ml water. Sip throughout — start before you feel thirsty, finish before the session ends.
