Product Review

The Purity Products R & D team has formulated Zestosterone , a unique blend of researched nutraceutical ingredients that can help maintain healthy testosterone levels.*

Finally, there's a science-based way to be proactive about testosterone! Zestosterone Proprietary Blend contains calcium fructoborate, a unique and patented form of the trace mineral boron found in fruit and vegetables. Boron is believed to play an important role in the metabolism of vitamin D and steroid hormones.*

Among its many benefits, Vitamin D is also helpful for testosterone support.* Zestosterone provides the exact amount used in a recent study showing that 3332 IU of vitamin D given as a daily supplement raised testosterone levels in men deficient in Vitamin D. (Pilz S, et al. Effect of vitamin D supplementation on testosterone levels in men. Horm Metab Res. Dec 10, 2010.)

Testosterone is a pivotal hormone positively correlated to a man's energy level, strength, fitness, mood, brain function, vigor, virility and libido. To further support healthy testosterone levels, ZestosteroneTM also features three ingredients specially selected for testosterone and prostate health supporting benefits.
