HYDRATION is important for all aspects of health and is especially important for athletes and those who exercise intensely or for long periods of time. Dehydration can cause fatigue and affect physical performance by reducing strength and aerobic capacity, so it is essential to keep your hydration levels at their peak to maximize performance and ensure optimal recovery. The HYDRATION formula is designed to be used at any time during training: Before training or before competition - to ensure you go into training as prepared as possible. During training - to optimize maximum performance. After training - to aid recovery.
