Do you want to refuel during longer and harder training sessions mith more than just electrolytes and carbohydrates? Then you should try Isomax, PowerBar's isotonic sports drink with caffeine. Isomax powder not only provides you with carbohydrates and electrolytes, but also 75 mg of caffeine per serving; caffeine can help improve concentration. It also contains 400 mg L-Arginine per serving, providing the body with a protein building block in the form of a free amino acid. Isomax is an ideal choice for your harder training sessions or competitions.

There is a small hole in the foil seal under the lid of all our powder cans. This hole is necessary and is designed to prevent the can from warping by equalising any pressure during transport. It does not compromise the quality of our products in any way.
