The Minerals you’ve Been Missing: Sleep deeper, recover faster, and increase muscle mass.*
While NutraKey’s Z Optima is just a simple mineral formula, according to a clinical study with NCAA athletes, supplementing with zinc, magnesium, and Vitamin B6 has shown to be an effective way to increase lean muscle mass, speed up recovery, and boost testosterone. From professional athletes to amateur bodybuilders, the Z Optima formula is one of the least-contested and most effective supplements on the market.*
AN ANABOLIC POWERHOUSE
While the ingredients in Z-Optima are not meant to directly promote testosterone and hormone production, athletes supplementing with this formula have experienced as much as a 30% increases in testosterone levels and a 5% increase in insulin-like growth factor (IGF-1) over several weeks of use.1 Athletes taking a placebo actually saw these hormone levels decrease by 10% and 20%, respectively, over the same time period.*
TAKE YOUR WORKOUTS TO NEW HEIGHTS
With the added metabolic benefits of vitamin B6, magnesium and zinc supplementation is important and effective for healthy growth in both athletes and bodybuilders alike. NutraKey’s Z-Optima formula has been clinically proven to significantly increase anabolic hormone levels, increase both free and total testosterone, boost muscle strength, and promote deep, replenishing sleep.*
