Zym Endurance is a new portable electrolyte drink. Pocket sized tubes are filled with 10 tablets and provide a refreshing and easy source of essential vitamins and minerals lost during exercise. And the tubes compact dimensions enable easy stashing for whenever you might need a boost.

Instead of handling messy powders or lugging around bottles of sports drinks, Zym packs all you need for proper hydration in the palm of your hand.

Available in Lemon and Lime flavour, one tube will cost you £4.95. We’ll be getting some on test soon. Zym will be available from next week through the Edinburgh Bicycle Co-op, Chain Reaction Cycles and Tri & Run, as well as online at www.gozym.com for more info.
