Vitamin D deficiency is the most common | Fix this = Better results at the gym!

Vitamin D is the most underrated vitamin which generally people don’t look upon!

In India, we get a lot of sunlight year-round, but ironically still it’s deficient in the majority of us. Out of all the vitamin deficiency, Vitamin D deficiency is the most common one!

Yes, you heard it right. 3 out of 4 people are deficient in it. First, let’s have a quick view of this wonder micro-nutrient.


What is Vitamin D?

Vitamin D is a fat-soluble vitamin which is a.k.a the SUNSHINE VITAMIN. Most essential one for the absorption of CALCIUM and other minerals.

Just like calcium, it is equally important and responsible for building and maintaining stronger bones & muscles. In fact, it can also gradually increase the bone density.

This is considered more of a HORMONE than a vitamin as mostly every cell and tissue in our body has receptors for it.

Influences many factors like bone and joint health, fractures and injuries, energy levels, immunity, body fat levels, mental ability i.e cognition, heart problems, hair fall, diabetes, delayed wound healing, hypertension, etc. and also YOUR MUSCLE HEALTH!


The major cause for the deficiency

The biggest cause for not getting enough of this vitamin is GETTING LESS OF SUNLIGHT. Yes, sunlight is the most abundant source of getting it. Hence the name sunshine vitamin.

People have mostly become sedentary staying busy working in their offices. Sadly when they come back home, there is no sun.

Plus, food sources have very negligible amounts of it which makes it the second big cause for having low vitamin d levels!

Though many of them have realized this and they have started taking steps to fulfill its requirements.


Best sources which provide Vit D

Vitamin D foods include fatty fishes like Salmon & Tuna, Dairy products (fortified ones), Mushrooms, Egg yolks, Cod Liver Oil, etc. They all can give you their dose naturally.

But the problem is, as mentioned in the above paragraph, very little of it comes from the diet and for getting the required amounts of this vitamin, you gotta have these food sources in enormous amounts. Even the food options are limited.

Sources of Vitamin D - Supplementation

Plus, so much adulteration also gives it a solid reason to add it up in a supplement form (mainly Vitamin D3 – Cholecalciferol).

If you are looking out for the natural ways to get it, exposure to the sun & having a sunbath/suntan once or twice a week would be the best option.

Those who already be out in the sun a lot, there is less for you to worry about.

Now you know the secret to why old-school bodybuilders relied so much on sun those days. It wasn’t just for having that tan. D worked like an ANABOLIC for them. They felt a boost in their strength, performance, and endurance.

Just make sure you don’t apply any sun-blockers / sun-screen lotions before getting exposed to the sun. It can reduce the synthesize of vitamin d up to 95%.

In a nutshell, SUNLIGHT & Supplementation are the only two best considerable sources giving you that desired D!
