How do our bodies make vitamin D?

When you go outside on a sunny day, your exposed skin will make vitamin D3. If we’re getting technical, this process happens when ultraviolet B (UVB) radiation from the sun triggers the 7-dehydrocholesteol to produce D3. Plants like mushrooms also go through a similar process to make vitamin D2.

What does vitamin D do in the body?

Vitamin D is one of the body’s most important vitamins, helping it with a variety of tasks:

The immune system: vitamin D contributes to the normal function of the immune system

Bone and muscle health: vitamin D is very important for the body’s structural system and maintaining normal bone and muscle function. It also contributes to the normal absorption and utilisation of calcium and phosphorus.

Are you getting enough Vitamin D?

There are several factors that will influence your body’s ability to synthesise vitamin D, including being exposed to less sunlight, such as during the winter months (Oct-Mar) in the UK or wearing clothes that cover more of your skin in the summer months, having darker skin, and being over 65.

Not many foods contain natural vitamin D, that’s why some foods get fortified with it. Good food sources of vitamin D include: sardines, egg yolk, salmon, shrimp, fortified milks, fortified yoghurts, fortified cereal, and fortified orange juice.

How much vitamin D do we need every day?

Adults should aim to get a daily dose of 10 micrograms every day, which equates to 400 IU. 


Just one Holland & Barrett D3 tablet contains 25µg (100 IU), which can provide you with enough for your daily needs.


I am a vegetarian – do I need to take a vitamin D3 supplement?

Vegetarians could certainly benefit from taking a regular vitamin D3 supplement. 


This is because vitamin D3 can only be found in meat-based foods, meaning those on a vegetarian and vegan diet are more susceptible to vitamin D deficiency than those who eat meat.


Holland & Barrett Vitamin D3 25 µg tablets are suitable for vegetarians, making them an excellent option for veggies looking to supplement their diet. 


What are the health benefits of vitamin D3?

Vitamin D has a wealth of health benefits. 


It helps support bone health and contributes to normal absorption and utilisation of calcium and phosphorus.  


Ample amounts of vitamin D can also keep our muscles and teeth healthy.


One of the most established health benefits of Vitamin D is of course, that It contributes to the normal function of the immune system.


Why should I take a vitamin D3 supplement?

Between April and September, spending 15 to 20 minutes out in the sunshine can provide your body with your recommended daily vitamin D dose.

In the winter, it gets much harder to get vitamin D naturally. That is quite simply because we spend most of our time indoors.

That is also why a daily vitamin D3 supplement can help give you your dose of Vitamin D, just when it needs it the most.

In fact, government guidelines recommend that we should take a regular D3 supplement during the winter months. 


What exactly is vitamin D3?

Vitamin D3 is the form of vitamin D that is biologically active.


Compared to vitamin D2, which is another form of vitamin D, the body can absorb it more easily.


Vitamin D3 helps our bodies maintain their vitamin D levels during the winter when it is dark outside. That is because, when exposed to sunlight, our bodies produce vitamin D.


When sunlight is not available, we can struggle to keep our vitamin D levels topped up.


Surprisingly, vitamin D is actually a hormone. Once the body gets it through sunlight, it is converted to ‘activated vitamin D’ or ‘calcitriol’.
