Recently, a 14 member expert committee was convened by the Institute of Medicine, at the request of the United States and Canadian governments to examine data of nearly 1,000 publications to determine how much vitamin D and calcium people were getting, and how much was really required for optimal health.

The committee reported that for the most part individuals diets and exposure to sunlight were sufficient to meet the body's needs for Vitamin D and calcium and did not warrant the use of supplementation. "For most people, taking extra calcium and vitamin D supplements is not indicated," said Dr Clifford Rosen, a member of the panel and an osteoporosis expert at the Maine Medical Center Research Institute.

The report has further elaborated that only adolescent girls may be consuming less than the required amount of calcium. It also states that for older women, too much vitamin D and calcium may increase their risk for kidney stones and some evidence even suggests that excess calcium can increase the risk of heart disease.

Vijayalakshmi Iyengar Newer studies (Nov 2010) suggest that we may need more vitamin D than presently recommended to prevent chronic disease. Emerging research supports the possible role of vitamin D in protecting against cancer, heart disease, fractures and falls, autoimmune diseases, influenza, type 2 diabetes, and depression. Many health care providers have increased their recommendations for vitamin D supplementation to at least 1,000 IU. Its best you consult our personal primary physicians to see if you are getting sufficient Vit D.

Sunil kumble What are the vegetarian sources of Vitamin D? Are vegetarians more prone to defeciency than non vegetarians? Can increasing diary products for calcium make up for reduced Vitamin D ?

Poonam Hello Mr Kumble,
Fortunately, adequate exposure to sunlight can take care of the daily requirement of vitamin D for vegetarians, so they must consciously increase their exposure to the sun (taking care of the factors which affect vitamin D synthesis). Unfortified dairy products do not contain large amounts of vitamin D.

Sunil Kumble Hello Ms Poonam
Recently there was an article in the papers in N.Delhi that studies have shown that exposure to sunlight is not sufficient for VIT D requirement and most Indians suffer from a deficiency they may need supplementation. Is that correct?

Poonam Hello Mr Kumble,
Fortunately, India has plenty of sunlight, but, Indians probably do not get adequate exposure to the UVB rays which are needed for the synthesis of Vitamin D. Indians also need longer exposure because dark skin interferes with the absorption of the rays. These could be some of the reasons for the deficiency.

Manoj-Bhasin all elders in my family have strong bones and have lived long lives without any broken bones. Do genes play a role in protecting you and your bones.
Do I need supplements knowing I probably have good genes for strong bones.

Vijayalakshmi Iyengar Hello Mr Bhasin
Even if you are genetically predisposed to strong bones it largely depends on your diet- for Calcium and Vitamin D, your exposure to sun, your activity, your constitution and a whole lot of other things to determine if you as an individual have strong bones. Unless we know your daily diet composition & portion size, your activity history & and current regular activity level we cannot comment on whether you receive sufficient nourishment to compliment your genes.
We suggest you register on our site for at least 1 month and enter the daily diet and activity log to get more answers.
Thank You

Meena I have my breakfast of cereal and milk and some fruit and then go for my daily walks. Am I getting adequate Vitamin D as I walk 45 minutes specially on sunny days?
How much vitamin D does my body absorb with spending 1 hour in bright sunlight?
Is that enough?
I eat Kelloggs raisin bran which supposedly gives me enough calcium.
Do I still need more supplements?

Vijayalakshmi Iyengar Hello Meena
Normally for adequate Vitamin D formation in your body you probably need from 5 to 30 minutes of exposure to ultraviolet B (UVB) rays in sunlight on your face, arms, back or legs (without sunscreen) twice every week. Again the amount of exposure also depends on the time of the year. In winters (Nov –Feb) especially north of the 42-degrees latitude, you may not get sufficient vitamin D so may need to consult you r GP.
With regard to intake of calcium? Can you provide us your entire day’s diet with portion sizes Meena? (Especially of calcium sources like greens, all diary products and nuts etc)
We would also like to know your age and how active you are.
Thank you

Poonam Hello Meena,
Usually 5-30 mins of exposure to sun is sufficient to produce the desired amount of Vitamin D in the body. The level of exposure needed depends upon skin type (dark skinned individuals need more time), age (the elderly need more exposure), climatic conditions and amount of skin exposed to the sun. Other than sun exposure a healthy diet including fish, egg yolk, fish liver oils and fortified foods help in supplying natural vitamin D to the body.
We will have to take a look at your entire day's intake to be able to tell you if your calcium intake is sufficient or not.
