It's strongly recommended that you take a vitamin D supplement during the winter.


Because the vast majority of our daily vitamin D comes from the sun. And during the winter in the UK, the sunlight often isn't strong enough to give us enough vitamin D. (Plus, we probably spend less time outdoors when it's cold and yuck.)

But why do we even need vitamin D? What would happen if we didn't take a supplement or get enough sunlight?

In this article, we'll be explaining the benefits of vitamin D, as well as debunking the myths on what vitamin D can do for your health.


What Vitamin D Does For Your Body (And What It Doesn't Do)

People often ask whether vitamin D can give you energy, help with skin problems like psoriasis, help with arthritis, keep you awake, help with weight loss, and so much more.

But is this really the case?

Let’s cover each of these questions below: 

Will vitamin D… 

… help me lose weight?Getting a sufficient amount of vitamin D everyday can help to keep your hormone levels balanced which could enhance weight loss and fat burning. Vitamin D can also decrease the risk of depression and lethargy – both of which can make it more difficult to lose weight.

… give me energy?Yes, if you are deficient in vitamin D, then taking a vitamin D supplement will likely boost your energy levels. This is why vitamin D is great for fighting winter fatigue. 

… help my skin? – Vitamin D plays a very important role in skin protection and rejuvenation. It contributes to skin cell growth and repair, and can also help prevent premature ageing. This is why the sun is so good for our skin (in the right doses), and why we need to supplement vitamin D during the winter when we don’t get as much sunlight.

… help me tan? – Despite being named the sunshine vitamin, vitamin D will not make you tan. That being said, it’s thought that vitamin D3 can help to protect the skin against UV damage. This means that, if you are outside trying to get a suntan, D3 could help to prevent burning and health damage.

… help psoriasis? – Research indicates that, since vitamin D can help to strengthen the immune system, it could help to treat autoimmune conditions like psoriasis internally. 

… help my arthritis? – Vitamin D’s main role is helping the body to absorb calcium which is what keeps our bones and joints strong. Therefore, it could help to relieve symptoms of rheumatoid arthritis. 

We mentioned there that vitamin D’s main job is helping the body to absorb calcium, which leads us to our next point: what is vitamin D for? What exactly does this vitamin do and what is its purpose in the body?

Vitamin D helps the body to absorb calcium and phosphorus. These are both vital for:

  • Keeping the bones and teeth strong
  • Keeping the muscles healthy
  • Keeping the immune system healthy
