What is Vitamin D?

"Sunshine Vitamin aka Vitamin D is a steroid hormone that our body produces from cholesterol when our skin is exposed to the UVB rays of the sun. A perfect gift from nature, as vitamin D is necessary for stronger immunity, proper bone health, building muscles, reversing insulin resistance, reducing joint pain, preventing cancer, reducing weight etc," says Ridhima Batra, Clinical Dietitian, Certified Diabetic Educator, Specialist Sports Nutritionist and founder of Nutrition Defined.

How we get Vitamin D from sunshine

"Vitamin D can only be synthesised with UVB rays. When these rays are absorbed into our skin, it converts into a previtamin D3 (an inactive form) which further in the liver and kidney is converted into the active form of vitamin D3. Since it's a fat-soluble vitamin, it can be stored in your body for a long time," says Batra.

But is exposure to sunlight enough for our daily Vitamin D requirements. The answer is - not for all. People who don't have access to proper sunlight, older people or people with darker skin tones face difficulty in meeting Vitamin D levels because of high melanin (a compound that protects against skin damage) as this reduces the amount of UVB light absorbed in the skin. Overweight and obese people also need more Vitamin D depending on their body size.

How to get Vitamin D from foods or supplements

- Foods that one should include for Vitamin D are fatty fish, seaweeds, algae, egg yolk, mushrooms, cod liver oil, spirulina and fortified foods like milk, tofu, yoghurt, orange juice, cheese etc.

- For oral supplementation, it's absolutely safe to take 1000 IU per day. However, do check with your doctor or dietitian on the proper dosage and duration as an excess amount of vitamin D in the body can also lead to toxicity.

How Vitamin D can help you lose weight

As per studies, vitamin D can potentially reduce the formation of new fat cells in the body and can also suppress the storage of fat cells effectively reducing fat accumulation.

"Vitamin D can increase the levels of serotonin (a neurotransmitter that affects everything from mood to sleep regulation) and testosterone levels that play a significant role in boosting your metabolism, causing your body to burn more calories, controlling appetite, increasing satiety, reducing body fat and sustaining long-term weight loss," says Batra.

So if you suspect low vitamin D levels, and are experiencing symptoms like fatigue, insomnia, bone pain, depression, hair loss or muscle weakness, consider getting your blood test done to rule out a deficiency.
