Tương tác
May interfere with the absorption of copper, leading to reduced copper levels or copper deficiency. May reduce the absorption of tetracyclines, penicillamine, oral Fe, trientine and vice versa. May decrease the absorption of quinolones (e.g. ciprofloxacin, levofloxacin, ofloxacin). Reduced absorption with Ca salts.
Tương tác với thức ăn
Reduced absorption when taken concurrently with phytates (found in bran, whole grain bread) and foods that are high in fibre, Ca or phosphorous.
Tác dụng
Description: Mechanism of Action: Zinc sulfate is a mineral supplement which is essential for many different processes in the body. Zinc is a cofactor of various enzymes which helps the body's natural defence against damaging free radicals and helps boost immune function. It also plays an important role in maintaining structure in nucleic acids, protein and cell membranes and is involved in the function of the hormone insulin in the utilisation of carbohydrates. Additionally, it is essential for normal growth rate, development of the reproductive organs, normal function of the prostate gland and the healing of wounds and burns. Pharmacokinetics: Absorption: Incompletely absorbed from the gastrointestinal tract. Bioavailability: Approx 20-30%. Distribution: Widely distributed throughout the body with the highest concentrations in the hair, eyes, male reproductive organs and bones; lower levels are present in the liver, kidneys and muscles. Crosses the placenta and enters breast milk. Plasma protein binding: Approx 50-80% to albumin, approx 7% to amino acids, and the remainder to α2-macroglobulins and other proteins. Excretion: Primarily via faeces (40%); urine and perspiration (small amounts).
