60 to 90 Vitamin D3 4000 IU
Vitamin D deficiency is associated with muscle weakness and is common among seniors. Even in healthy elderly people, the lack of vitamin D is accompanied by a reduction in muscle mass and muscle strength.
Seniors are prone to develop vitamin D deficiency because of decreased dietary intake, diminished sunlight exposure, reduced skin thickness, impaired intestinal absorption and impaired hydroxylation in the liver and kidneys. Adequate levels of vitamin D in the body can protect an individual from muscle deterioration and weakness that causes falls, a leading cause of death among the elderly. In addition, research shows that at certain high levels, vitamin D can protect an individual against disease formation.
