Vitamin D is an underrated nutrient in the world of nutrition. It encourages the absorption of calcium and phosphorus in the body. Your body produces vitamin D when your skin is exposed to sunlight. Only direct sunlight rays can produce vitamin D, it cannot be produced if you are sitting inside your home or in a car as natural sunlight cannot penetrate the glass or any other object. The only reliable way to generate a sufficient quantity of vitamin D, to fulfill the need of your body is sunlight. It is not possible to get an adequate quantity of vitamin D from your diet or prepare in the laboratory as medicine. If you are residing far from equator i.e. in Canada, UK and most of the states of the USA, you need longer exposure to the sun to generate vitamin D for your requirement. People with dark skin pigmentation need much more exposure to the sun in comparison with the people of light skin to produce the same amount of vitamin D.
Most of the pregnant women and old age people are at the risk of deficiency of vitamin D as they are less likely to spend their time in the sun. In older age, there are few receptors in the skin that convert sunlight to vitamin D. People over the age of 65 years are at very high risk of vitamin D deficiency as they may not get the vitamin in their diet or may have a problem in absorbing vitamin D from their diet. Supplement of vitamin D is necessary for older people, people living far from the equator and dark-skinned people who need more exposure to the sun. Dark-skinned people due to sunlight deficiency are at the risk of the prostate cancer epidemic.
Vitamin D plays an important role in maintaining proper bone structure. It is activated by your kidneys and liver before use. Kidney disease or liver damage can greatly impair your body’s ability to activate circulating vitamin D. Vitamin D is one of the most powerful healing chemical in your body and your body produce it. An adequate level of vitamin D can be restored through exposure to sunlight. Body fats work like a kind of storage of battery for vitamin D as only a week time exposure to sunlight without sunscreen can make up for about one and a half months of no sunlight exposure. Anti-oxidants greatly boost your ability to handle sunlight without burning and a good source of anti-oxidants is superfood like pomegranate, Acai and blueberries, etc.
