What is it?

Holland & Barrett Vitamin D3 contributes towards the maintenance of normal bones, muscle function and the immune system.

  • Supports the Normal Function of The Immune System
  • Contributes To the Maintenance of Normal Bones and Muscle Function
  • Suitable For Vegetarians

What Are the Benefits of This Supplement?

  • Vitamin D is one of the body’s most important vitamins, helping it with a variety of tasks: Vitamin D contributes to the normal function of the immune system and is very important for the body’s structural system, maintaining normal bone and muscle function. Vitamin D3 also contributes to the normal absorption and utilisation of calcium and phosphorus.
  • When exposed to sunlight, our bodies will naturally make vitamin D3. This process happens when ultraviolet B (UVB) radiation from the sun triggers the 7-dehydrocholesteol to produce D3. Research suggests that everyone over the age of one years should have a daily intake of at least 10µg of Vitamin D per day to protect bone and muscle health. Government advice is that everyone should consider taking a daily vitamin D supplement, especially during the autumn and winter.

What is vitamin D3 and why is it better for us than D2?

It might surprise you to hear that vitamin D actually comes in two forms: D2 and D3.


Vitamin D3 is its biologically active form and is more important for our health. 


That is because the body absorbs it better. It also helps us maintain our vitamin D levels throughout the winter months. 


Your body produces vitamin D when your skin is exposed to sunlight. That is why it is also known as the sunshine vitamin. 


When the body gets vitamin D, it becomes a hormone known as activated vitamin D or, less commonly, calcitriol.  


Our body is capable of making approximately 90% of the vitamin D we need, but we require enough UV light to do so. 


You can also find vitamin D in a range of foods, including wild mushrooms, milk, and cereals. 


Because it is difficult for us to get enough vitamin D in the winter months, government guidelines recommend taking a regular D3 supplement.

Do vegans need a D3 supplement?

While vitamin D is found in a range of foods, D3 is only found in meat-based products.


As a result, vegans and vegetarians should consider supplementing their diet with a daily vitamin D3 tablet.

How much vitamin D do we need?

Adults need 10mcg of vitamin D every day. This is equivalent to 400 IU. 

Each Holland & Barrett D3 tablet contains 10µg (400 IU) of vitamin D, meaning just one supplement contains your recommended daily amount.

To put this into context, 15 to 20 minutes of direct sunlight between April and September can give you all the vitamin D your body needs. 

It gets much harder to get vitamin D outside these months, which is why a regular vitamin D3 supplement can keep you healthy.
