Vitamin D sources
1. The Sun
The main source of Vitamin D is the sun. Our body produces Vitamin D if it’s exposed to sun. However multiple factors as time of day, season of the year, geographic location or sunscreen directly affect vitamin D synthesis.
Usually 10-15 minutes of sun exposure, several times a week, can make a huge difference and increase the vitamin D production.
Vitamin D is not often found in food. However the flesh of fish like tuna and salmon as well as fish liver oils are good and rare sources. Vitamin D is also found in fortified foods.
3. Nutritional Supplements
Supplements are a sure source of vitamin D. They are usually a must for people living in areas with low sunlight or areas which are highly polluted.
Vitamin D and weight loss
A daily supplement of 83 mcg of vitamin D keeps the heart and the blood vessels healthy during a weight loss process. Benefits are registered for both males and females, no matter how many kilograms one loses or how much fat tissue the individual burns. As a conclusion vitamin D boosts weight loss and, in the same time, keeps the cardiovascular system healthy.
US researches have recently proved that adding vitamin D to a low calorie diet results in an obvious weight loss boost. Every 1 ng/mL plasma level increase of 25-hydroxycholecalciferol (a measure for vitamin D level in the human body) resulted in an 0.2 kg (0.44 lb) weight loss boost in all individuals which took part at the research. This means that all individuals which followed the low calorie diet imposed by the research and also added vitamin D supplements to it lost 0.2 kg or 0.44lb more as the ones that did not took the vitamin.
