Zinc is present in trace quantities throughout the body and is required for many important functions (over 200 enzymes require zinc as a co-factor). Higher levels are found in muscles, bone and the immune and nervous systems, but regular intake is essential to maintain body levels. The recommended daily intake of zinc is around 15mg. There are many thousands of published medical papers detailing the importance of zinc in mammalian biochemistry, demonstrating it’s importance preconceptionally, during pregnancy (for mother and baby) and childhood, and for normal mental and physical health as an adult. Zinc is required for cells to be accurately reproduced, for the immune system and for metabolism of essential fatty acids. A diet containing highly refined foods may be deficient in zinc (and other minerals and vitamins) and the zinc demands of growth, infections, pregnancy & lactation, and wound healing increase an individual’s requirement for zinc. Zinc availability is dependent on the presence of other minerals including iron, selenium, copper and manganese, and it is known that copper and iron supplements can reduce the absorption of zinc (zinc supplements are best absorbed on an empty stomach). Certain drugs and alcohol consumption are known to reduce zinc levels, as are digestive problems and diarrhoea. The elderly, pregnancy and those on restricted diets may also require extra zinc. Urine levels decrease in deficiency and increase with excess intake, but the normal range is very wide.

Clinical Indications:

Deficiency signs and symptoms include slow growth, infertility, hair loss, fatigue, various skin conditions, immune deficiencies, impaired taste or smell, behavioural problems, impaired wound healing and white spots on the finger nails. Delayed growth, frequent infections, skin problems, slow wound healing, impotence and low fertility may all be attributable to low zinc levels.
