Study shows vitamin D is good for seniors

American specialists tested samples of brain tissue from 209 deceased elderly people and, as an unprecedented result, found that vitamin D exists in four main areas of the brain. However, experts could not confirm the exact relationship between the vitamin and brain functions, and whether it is even one of those responsible for preventing dementia.

However, Dr. Kyla Shea, lead author of the study from Tufts University in Massachusetts, said: "We now know that vitamin D is present in reasonable amounts in the human brain and appears to be correlated with less decline in function cognitive”.

She also explained that more research needed to be done to be able to identify the neuropathology that the vitamin is linked to in the brain before they started designing future interventions.

Vitamin D

Vitamin D is a hormone steroid that is not naturally produced by the human body, its main source being direct exposure to sunlight and food. This hormone has numerous qualities already proven, being able to act in bone health, immunity, growth, musculature and metabolism.

The deficiency of this vitamin reduces the levels of calcium present in the body, causing serious damage. In children, this damage can be in ossification and growth, and in adults, it can cause osteopenia and osteoporosis. In addition, it can lead to impairment of muscle strength and contractility.

There are still many studies being done on this hormone and there are no uniform recommendations for its use. Depending on the age and condition of the person, the values ​​may change, so it is recommended to consult a doctor before supplementing with vitamin D.
