Science In Sport GO Electrolyte Powder (Blackcurrant, 500g) – High-Carb Energy & Isotonic Hydration Drink
Estimate delivery times: 3 - 5 business days
Pairs well with
SiS GO Electrolyte Powder (500g)
Exhaustion sets in fast when sweat depletes core minerals and drains glycogen stores during grueling endurance rides or long runs. Packing 36g of fast-absorbing carbohydrates and targeted sodium into every serving, this isotonic blend prevents cramping and keeps stamina high without heavy stomach discomfort.
Precision Isotonic Balance Over Flat Water
Plain water fails to replace vital salts lost through heavy sweating, often leading to hyponatremia, sloshing, and sudden power drops. Formulated with an exact ratio of carbohydrates and sodium, this clean powder rapidly drives fluid into bloodstream channels while delivering immediate energy directly to working muscles.
Targeted Fuel & Recovery Benefits
- 36g Rapid Carbohydrates: Delivers immediate, stomach-friendly glycogen replenishment to sustain pace through demanding training sessions and races.
- Sodium-Enhanced Hydration: Restores essential electrolytes lost in sweat to maintain optimal fluid retention and stop muscle cramping.
- 100% Vegan & Gluten-Free: Formulated with high-grade plant ingredients, making it completely safe for athletes with dietary restrictions.
