Frequently Asked Questions

How can USN’s endurance supplements help me reach my goals?

  • Hydration: endurance athletes need to stay hydrated to keep their bodies cool and lubricated. Electrolytes also play an important role in hydration as salts and mineral levels in the body need to be replenished to avoid fatigue and cramps. Products like Zero Sugar Hydrator, Pro Enduro will help keep you hydrated.
  • Energy: the nature of endurance sport requires longer-lasting and slower-releasing energy sources to cater for the extended period over which these events occur. That means higher carbohydrate levels for energy production. Products like Pro Enduro or Epic Pro will help keep you going for longer.
  • Recovery: the body must recover properly from intense and prolonged sessions to replenish fatigued muscles or even to repair the microscopic tears in muscle fibre following intense exertion. Epic Pro, Amino X, Pro Recover or Zero Sugar Hydrator can help your muscles recover much faster. Focus: keeping your mental state on par is a big part of any endurance activity. Epic Pro and Amino X can help increase your focus.
