This high potency formulation is specifically designed to maximise the vital nutrients required to optimise the potential for male reproductive fertility. Ideally, take at least 90 days ahead of planned conception. Zinc is a mineral essential to many body processes including the maintenance of normal cognitive function, vision, fertility and reproduction, hair, skin and nails and the immune system. Zinc also contributes to the normal metabolism of fatty acids and macronutrients. Selenium contributes to normal spermatogenesis (the creation of sperm), to the maintenance of normal hair and nails, the normal function of the immune system, normal thyroid function and for the protection of cells from oxidative stress. This 'oxidative stress' appears to be a major factor in many human diseases. Copper contributes to normal energy-yielding metabolism, the maintenance of normal connective tissues, to the normal pigmentation of hair and skin, the normal function of the nervous and immune systems and for the protection of cells from oxidative stress. This 'oxidative stress' appears to be a major factor in many human diseases. Vitamin E has a role in the protection of cells from oxidative stress. This 'oxidative stress' appears to be a major factor in many human diseases. Vitamin C plays an essential role in numerous areas of human health. Vitamin C contributes to normal collagen formation for the normal function of bones, cartilage, skin, gums and teeth. Vitamin C also enhances iron absorption and the normal energy-yielding metabolism. Vitamin C aids in the maintenance of the immune system including during and after intense physical exercise. Vitamin C contributes to normal psychological function, the functioning of the nervous system and contributes to the protection of cells from oxidative stress. This 'oxidative stress' appears to be a major factor in many human diseases. B12 contributes to normal homocysteine metabolism and red blood cell formation, to the reduction of tiredness and fatigue, the energy-yielding metabolism, to normal psychological function and the functioning of the nervous system. Vitamin B12 also contributes to the normal function of the immune system.
