THE SCIENCE

HYDRATION SAFETY

2.5XCRAMP RESISTANCE

Proper electrolyte hydration more than doubles the time you can run before muscle failure sets in.

Subjects exercised for 36.8 minutes before cramping with electrolytes, compared to only 14.6 minutes without.

OXYGEN EFFICIENCY

16%LONGER RUNS

Your engine becomes more efficient, allowing you to maintain pace with significantly less oxygen.

In a double-blind study, dietary nitrates reduced submaximal oxygen cost by ~5% and extended time-to-exhaustion by 16%.

EXERCISE TOLERANCE

12%GREATER ENDURANCE

Clinically proven to speed up oxygen kinetics and increase how long you push before failure.

Subjects supplementing with 6g of L-Citrulline saw a 12% increase in exercise tolerance and 9% higher peak power.
