SANDERSON Triple Zinc FX combines three organic, highly bioavailable forms of zinc for optimum potency. Zinc is an essential mineral required for over 300 enzyme reactions, important structural and regulatory roles in the human body. As such it plays a vital role from growth and brain development in the young to supporting eye health in later years. Zinc supports immune function, recovery and wound healing; maintains healthy skin, and supports reproductive health and fertility. Severe zinc deficiency is rare, but marginal deficiencies are more common resulting from poor diet, depletion by medications and low levels of zinc in New Zealand soils.
