Vitamin- D Deficiency
We often hear elder people say “You are not getting enough sunlight, go outside. It’s important for your body- vitamin D.” But do we really know if that’s the case? Let’s figure out the logic behind the situation.
What exactly is Vitamin D?
Vitamin D is a fat-soluble vitamin that is found in a number of food products and is majorly produced by our body when we expose our skin to natural sunlight. It has two forms namely, Vitamin D2 and D3. Vitamin D2 can be found in fortified foods, over-the-counter supplements, and plant foods. Vitamin D3, on the other hand, is found in animal foods, fortified foods, supplements and is also made inside our body when our skin is exposed to ultraviolet radiation of the sun. Apart from this, a major function of Vitamin D is that it helps our body absorb calcium (i.e. a main building block of bones).
Why do I need Vitamin D and how much is a deficiency?
Now is the time to really understand the logic behind the popular elderly quote mentioned above. Let’s discuss why do we need vitamin D-
- Firstly, it supports bone health by absorbing calcium.
- Regulates blood pressure
- Modulates immune system
- Promotes muscle health
We say too much or too little of anything is bad. While too much Vitamin D intake can cause nausea, vomiting, constipation and weight loss. On the other hand, our constant lifestyle choices involving indoor long working hours, an unstable diet have caused a deficiency of Vitamin D in the majority of the population. But how do we know if the vitamin D level in our body is on the lower or upper end?

Causes of vitamin D deficiency.
- Non-consumption of recommended levels of vitamin D: As discussed earlier, there are a number of plant and animal-based foods that include vitamin D in them. Some examples of these food items are- orange juice, milk, liver, beef, egg yolk, cheese, tuna, salmon, etc. Non-consumption or less consumption of such food items can result in low Vitamin D levels in our body.
- Limited exposure to sunlight: Since our body generates Vitamin D when exposed to ultraviolet rays of the sun, limited exposure to it can result in deficiency of Vitamin D.This can happen if we cover our skin fully while stepping in the sun, or we live in a geographical location that doesn’t receive a lot of sunlight.
- Your kidneys cannot convert vitamin D into its active form: Due to rising age, our kidney’s efficiency of converting Vitamin D into its active form lessens. Because of this, the chances of vitamin D deficiency in old people is more.
- Obesity: A BMI (body mass index) of greater than 30 can result in lower vitamin D levels in a person. This is because fat cells keep vitamin D isolated and hence obese people have higher chances of developing Vitamin D deficiency.
