5 ways Vitamin D supercharges your body & mind

Vitamin D Basics

Vitamin D, also known as calciferol or cholecalciferol, is a fat soluble vitamin that human body can produce on its own. Naturally, vitamin D is produced when sunlight strikes the skin. You can also get vitamin D from several foods and supplements. Vitamin D from supplements has to pass through chemical processes before body can use it. Once it is ready for use, it plays a crucial role in maintaining calcium and phosphate levels in body. This aids in better bones, improved mental health, enhanced athletic performance and many more health benefits.

 

Health Benefits of Vitamin D

Calcium Hemostasis

Calcium is a crucial mineral that assists in several important body functions, for instance, it takes part in bone mineralization, aids in blood clotting, ensures optimum muscle contractions and so on. Vitamin D is important as it helps to keep blood calcium levels within normal range. Vitamin D accomplishes this by increasing calcium absorption through the gut and by decreasing its excretion through the kidneys (1) (2).

Bone Mineralization

Vitamin D helps with bone mineralization in two ways. First, it improves blood calcium status. Second, it triggers the function of bone forming cells (osteoblasts) in bones (3). Results of studies have shown that supplementation with vitamin D and calcium increases bone strength and decreases the incidence of fracture (4).

Mental Performance

Improved cognition is another important feature of normal vitamin D levels. Researchers now speculate that age related decline in cognition maybe associated with fall in vitamin D levels. The risk of dementia and neurological diseases (like Alzheimers) increases several folds with increasing age. Researchers have also found that as much as 50% individuals with poor cognitive functions are deficient in vitamin D 5) (6). Furthermore, supplementation of this vitamin may assist with better mental performance and cognition.

Athletic Performance

Coaches have long recognized that exposure to sunlight improves athletic performance. This fact has been validated by recent research as well that ties together the missing links between vitamin D levels and athletic performance. Vitamin D, as previously mentioned, strengthens bones. In addition, higher vitamin D intake or better exposure to sunlight, which will improve vitamin D status, improves the bulk and functioning of skeletal muscles too (7). Results of a research conducted at the Atascadero State Hospital, USA showed that exposure of vitamin D deficient athletes to sunlight improved their performance and also decreased the risk of sports related injuries/conditions (8).

Alkaline Benefits

Vitamin D may assist in the alkalization of urine- which is more favorable urine pH- as better vitamin D levels increase phosphate secretion into the urine that tends to increase urine pH (9).

 

How much Vitamin D do you need?

According to the US department of health, an average adult (including pregnant and lactating females) should get as much as 600 IU (International Units) of vitamin D from diet, sun exposure and supplements.
