Zinc
An essential mineral for human nutrition. Zinc is an important component of many enzymes and proteins and has important antioxidant, immune and anti-inflammatory activities. Zinc also plays a role in normal reproductive and sexual functions for both men and women. It’s well known that marginal zinc deficiency can impair testosterone production in men.
See the Zinc review for more information; also the Linus Pauling Institute Micronutrient Information Center.
