Micronutrients are the vitamins, minerals and other essential biochemical compounds needed to maintain the body's overall function and maximum efficiency. In fact, micronutrients may be considered more important for bodybuilders than calorie-producing nutrients precisely because of their ability to impact physiological functions.Without micronutrients, it's impossible to catalyze or facilitate the biochemical reactions that convert the food we eat into useable nutrients that enable growth, maintenance or even energy to fuel our metabolism. Vitamins help enhance the action of protein, causing muscle building and energy production. Minerals maintain the balance of fluids in our cells and help enhance muscle contractions.Even if only one of the critical substances is deficient, a bodybuilder's progress can be halted in its tracks without warning. Without these vital micronutrients, nothing happens. Virtually every energy production or muscle growth process a bodybuilder relies on is dependent on the right proportion of vitamins and minerals. Nutrient deficiency, which can occur during intense training, can sabotage any bodybuilders muscle growth efforts.STRONGMAN is designed to provide the complete package of vitamins, minerals and other essential biochemical compounds you need to maximize your muscle-building potential. Supplement science has come a long way in the last 25 years, and FUSION has put all that science into STRONGMAN.
