Adequate nutrition is essential for both optimal health and athletic performance. In fact, proper nutrition during training is one of the keys to success. Strenuous workouts can deplete the body of important nutrients, particularly minerals and water soluble vitamins. Exercise can also increase oxidation that, in turn, increases the production of harmful free radicals.
This complete nutritional plan provides a convenient way to achieve your daily nutritional goals. Each packet is easy to take with you to the gym, to work or when traveling.
