Blackmores Vitamin D3 assists in maintaining healthy bone density by providing minerals to the skeleton. Adequate levels of Vitamin D are essential for normal calcium absorption and healthy bones. Vitamin D also improves muscle strength in the elderly which may reduce the incidence of falls. People need regular exposure to sunlight on their skin to make vitamin D but should avoid exposure during peak UV periods. A significant number of Australians do not receive enough Vitamin D due to lifestyle and diet. Ageing decreases the skins ability to produce vitamin D.
