Selenium

Selenium is an important mineral which is contained in the
bodies antioxidant system. It is the co-ordinating mineral for
the enzyme glutathione peroxidase (powerful antioxidant) et al..
Vitamin E and selenium are synergistic ie. work better together
than they do separately. Like vitamin E selenium is an
Antioxidant slowing down aging and the hardening of tissues
through oxidation. Selenium should also be taken with vitamin C.

Males appear to have a greater need for selenium - almost half
of the bodies supply concentrates in the testicles and portions
of the seminal duct adjacent to the prostate gland. Selenium is
also lost in semen. Selenium is a relatively recent discovery,
little more than 20 years, and its importance in human nutrition
is only just being recognised.
