One of "America's Top Physicians," Dr. Costa lectures nationally and internationally on men's health topics. Dr. Costa is regularly featured in television, radio and newspaper interviews and has published articles in both professional journals and popular magazines. "Proper nutrition is essential for optimal athletic performance. I recommend the Mega Men Sport Vitapak. It provides a strategic combination of vitamins, minerals and other nutrients to fuel performance while supporting good health."

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.
