CO-ENZYME+ contains the organic forms of both zinc and selenium, both essential minerals for supporting male and female reproductive system health.  Zinc glycinate is the best absorbed form of zinc which supports reproductive health, regulates a healthy menstrual cycle and supports preconception health in females. Zinc  is also an essential trace mineral for oocyte maturation, egg activation, embryogenesis, implantation and placental development. 9 We use selenomethionine, an organic yeast derived form of the mineral selenium. In males or people who ejaculate, zinc protects sperm from oxidative damage and adequate zinc maintains normal sperm parameters. 7 The role of selenium in spermatogenesis and sperm motility is well established. 11
