Zincatest A liquid form of zinc that can be used to test how much zinc is detectable in the body (dependant on a taste test) and also can be used as a supplement in its own right eg for children who can’t take pills / capsules. Zinc is increadibly important for your immune function, sperm production, general growth, ability to deal with stress and pollutants / toxins. It is the only water-soluble mineral and is found in lots of leafy vegetables. Sadly, assuming there is any in the zinc-deficient soils that out produce grows in that then gets into the plant, it is mainly washed away in the food preparation and cooking processes. Therefore, almost everyone DOES need regular zinc supplementation. The Zincatest also acts as a way of ensuring that you have sufficient in th ebody, as with enough zinc, you taste buds work differently!
