"Zinc is essential for the reproductive organs of men perhaps even moreso than for women, and a chronic deficiency of it is one of the major causes of male infertility.  It rids the body of chemical poisons which enter through food, drink, and the air, as stated previously, and it also comprises as much as 15% of the content of semen, or at least it should, if the body is receiving proper amounts of zinc in the diet.  Most men it appears are not getting even the required daily allowance of 15 milligrams."

 

     Zinc however, should not be taken in isolation, unless it is in addition to the RDA of zinc taken with a multi-vitamin/mineral supplement.  This is owing to the fact that zinc is antagonistic to copper, meaning that it will steal copper from the body.  2 milligrams of copper are needed daily by adults to maintain, among other things, the suppleness of the veins and arteries, and thus prevent atherosclerosis, or hardening of the arteries.

 

     In addition, it is recommendable not to take more than around 50 milligrams per day at most, because amounts of 100 millgrams can cause nausea, and actually suppress the immune system, instead of strengthening it, as lower doses do.  Some of the manufacturers of supplements are currently producing 100 milligram tablets, and this is a serious mistake on their part.
