When it is absorbed and retained, it is used for tissue growth, which includes bone growth, and for turnover replacement. An excessive iron deficiency will lead to increased manganese absorption in humans. Therefore, iron deficiency could make someone more vulnerable to manganese toxicity. Also, this mineral is essential for the metabolism of carbohydrate, fats, and protein. Phosphorus depletion syndromes in humans are often the result of inappropriate ingestion of non-absorbable antacids.
Potassium deficiency causes urinary ammonium wasting.
Decreased total body potassium can lead to hypokalemia. ZINC aids in the digestion and metabolism of phosphorus and protein. It is a component of insulin and of male reproductive fluid. High intakes of calcium and alcohol, and a lack of phosphoruscan diminish the levels of zinc.
