Vitamin D deficiency predisposes to fractures. This shows once again a Swedish study of American adults over 65 years.

The officially recommended dose for the prevention of bone fractures in the United States is 800 units of the vitamin per day for people over 70 and 600 for younger people, which according to their experts reduces the risk of fractures by 30%. This amount of vitamin D can be obtained by consuming 200 g of salmon, 450 g of tuna, 35 sardines, 20 eggs, nearly 4 kg of cheese, 11 cups of fresh milk enriched with vitamin, 5 cups of yogurt. However, even with a well-planned regimen, researchers believe it cannot provide the amount needed to prevent food fractures.

The Center for Aging and Mobility at the University Hospital in Zurich estimates that the incidence of fractures of the femur in women will triple, and in men - 4 in 2050 due to the aging population. The number was derived from an analysis of 11 studies involving 31,000 people examining the effects of vitamin D and calcium.

Vitamin D helps absorb calcium from the bones, which ensures their strength. In addition, vitamin D has the ability to improve immunity and muscular endurance, which in turn also helps maintain health in adults.

There is a massively low level of the vitamin in the blood of the elderly American population.

According to researchers and experts, the recommendations for daily intake of the vitamin should be increased based on new data. So far, each of them recommends different doses ranging between 2,000 and 5,000 units.

Vitamin D deficiency predisposes to bone fractures and slow bone recovery, muscle weakness , osteoporosis and rickets in children. It must be prescribed to infants for the prevention of rickets. On the other hand, overdose leads to confusion, disorientation and kidney disease, which requires a really careful determination of the healthy dose for adults over 65 years in order to prevent bone fractures.
