Unfortunately, it’s estimated that as much as 75 percent of people, even those who stick to a healthy diet, have some kind of vitamin D deficiency. 

Although vitamin D can be stored in your body fat until it is needed, it’s not so easy to get enough vitamin D into your body.

The best source for vitamin D is still sunlight. The problem is that too much exposure to the sun can cause skin cancer. 

Pollution in big cities or seasonal changes (in the winter, the sun simply isn’t strong enough) are other reasons why we’re not getting enough vitamin D. Age plays a role as well since aging skin doesn’t absorb sunlight as well as younger skin.

So if we can’t get enough vitamin D from the sun, what about getting it from our food? Well, only few foods supply vitamin D in the significant amounts that you need (like wild-caught salmon). And we usually don’t consume large enough quantities of them.

That’s why doctors and nutritionists recommend vitamin D3 supplements. Not only do they last longer than their counterpart vitamin D2 but are also more similar to the natural vitamin D that you are getting through sunshine exposure. 

Vitamin D increases your immunity against Illness. It’s not surprising that people are more likely to get sick with the flu during the winter months when there is not enough sun.

One of the most popular benefits of vitamin D is that it strengthens your bones. It greatly reduces your risk to get a fracture and improves your balance. Vitamin D also limits the possibility for older people to develop sicknesses such as multiple sclerosis or osteoporosis.

Vitamin D is making your muscles stronger. It is also preventing falls by enhancing the response of your muscles.

With its anti-inflammatory features, vitamin D plays an important part in keeping your lungs healthy.

Having a sufficient amount of vitamin D can protect you against heart disease. People with low vitamin D levels tend to have higher blood pressure which can lead to a heart attack.  

One of the most significant benefits of vitamin D is its impact on your mood. Scientific evidence clearly demonstrates that the lower your vitamin D levels are, the more likely you are to feel blue. That’s also one of the reasons why many people generally feel happier when the sun is shining. 

Vitamin D deficiency has also been linked to depression. It’s no wonder that studies have proven vitamin D supplements to have similar positive effects on its patients’ moods as anti-depressants.

When you lack vitamin D, you feel hungry all the time, no matter how much you eat. When your vitamin D levels are back to normal, it creates a feeling of fullness and in that way aiding your weight loss.
