The use of vitamin D as a 'general tonic' in individuals who were not vitamin D deficient (or at risk of becoming deficient) was found to be largely fruitless.

While the nutrients themselves are important, the researchers found calcium and vitamin D supplements did little to reduce fracture risk or improve bone density in the healthy older adult population. In fact, calcium supplements may be doing more harm than good. Vitamin D: Vitamin D and metabolites are mainly excreted in the bile and faeces.Now, research has revealed it might be time to ditch two of our most popular vitamins.Ī review recently published in the Medical Journal of Australia found calcium and vitamin D supplements, often recommended to older Australians to prevent osteoporosis, offer very little benefit to healthy adults. Excess absorbed calcium excreted via urine. Metabolism: Vitamin D3: Hydroxylated in liver to form 25-hydroxycholecalciferol, then hydroxylated in kidney to form active metabolite 1,25-dihydroxycholecalciferol.Įxcretion: Calcium salt: Unabsorbed calcium mainly excreted via faeces. May be stored in adipose and muscle tissue for prolonged periods. Vitamin D: Vitamin D and metabolites binds to vitamin D -binding protein and are circulated in the blood.

Vitamin D3: Well-absorbed from GI tract in the presence of bile.ĭistribution: Calcium: Skeletal tissue, breast milk. It is necessary for the regulation and regulation of calcium and phosphate homoeostasis and bone mineralisation.Ībsorption: Calcium: Approx 33% of oral calcium absorbed via active transport and passive diffusive in small intestine. It is also used as an adjunct in the prevention and treatment of osteoporosis. Description: Calcium salt can be used in the prevention and treatment of calcium deficiency states.
