The male prostate gland contains and uses more zinc than any other tissue. The main transporter of zinc into prostate tissue is the amino acid arginine. A Man?s Zinc binds zinc to arginine in order to help direct it to the prostate tissue. Without adequate zinc, sperm production decreases, and the general health of the prostate weakens. A Man's Zinc also provides phytosterols, fatty alcohols from plants (extracted from soy oil in this case), known to support healthy prostate function.
