What OsteVit-D One-A-Week is used for

OsteVit-D One-A-Week capsules contain cholecalciferol.

Cholecalciferol is another name for vitamin D3.

OsteVit-D One-A-Week is used, as directed by your medical practitioner or pharmacist, for (a) treatment of vitamin D deficiency in adults and adolescents and (b) for the prevention of vitamin D deficiency in high risk individuals.

Vitamin D3 is a fat-soluble vitamin that helps your body absorb calcium and phosphorus, for strong, healthy bones and teeth. A diet with not enough calcium can lead to osteoporosis later in life. Adequate vitamin D and calcium is needed to help build strong bones and assist in the prevention of osteoporosis. OsteVit-D One-A-Week is not a source of calcium.

It is unlikely that adequate vitamin D levels can be achieved through the diet.

The main source of vitamin D is from the sun, however deficiency is common and it should not be assumed that Australians get enough vitamin D from the sun. People who may be at risk of being deficient are the elderly (particularly those in residential care), people with skin conditions where avoidance of sunlight is advised, those with dark skin (particularly if veiled), and those with malabsorption.

Ask your pharmacist or doctor if you have any questions about this medicine.

OsteVit-D One-A-Week capsules are only available from your pharmacist.
