| Zinc is an essential trace mineral that occurs in greater amounts than any other trace mineral except iron. Zinc at doses of 20mg and above may cause stomach upset and/or nausea so it should always be taken with food. This may be due to an induced copper deficiency. Note Food processing removes a large amount of zinc as well as other trace elements. Molasses has 42 times more zinc than an equal amount of white sugar. One Suggested Supplemetation Regime During any period of supplementation the zinc taste test should be repeated at appropriate intervals and the subsequent dose of zinc adjusted up to the required level. Zinc should be taken each day after food. Zinc sulphate is the most common (and cheapest) presentation but should be avoided due to the frequent occurrence of gastric irritation and dyspepsia. This is where the zinc is combined with an amino acid, which assists in its absorption. High doses of zinc will also tend to reduce the absorption of iron. |
