Vitamin D3 plays many crucial roles in your body


Contributes to normal immune system function 

Helps maintain normal muscle function

Supports normal bone and teeth

Contributes to normal absorption and utilisation of calcium and phosphorus

Supports normal cell division



The elderly

People who are home bound or in nursing homes tend to not get the sunshine needed to produce sufficient vitamin D. Also, the older you get, the harder it is for the skin to synthesise vitamin D.

People who are overweight/obese

They are more prone to vitamin D deficiency because fat cells tend to act as reservoir for Vitamin D – leading to lower levels.

Post-menopausal women

After menopause, it’s important to take steps to support bone health – taking a vitamin D is one of those steps.

Everyone during the winter

Not getting enough sunshine during dark winters means your body isn’t able to produce enough vitamin D.

People with limited sunlight exposure

Anyone who doesn’t spend enough time in the sun either due to occupation, being homebound or living in northern latitudes.

Anyone with digestive tract disorders

Conditions like celiac disease, Crohn disease, cystic fibrosis may affect your ability to absorb vitamin D from food.



There are not that many foods that are naturally rich in vitamin D (egg yolks and fatty fish, such as salmon, are two). While we do make most of our vitamin D with the help of sunlight, this production goes down during the darker months and whenever we’re not spending enough time outside.

But this isn’t the issue during the darker months only. What do we do in the summer? We stay in air-conditioned rooms and offices. And when we do go outside? We wear sunscreen – it can diminish vitamin D3 production by up to 95%! This makes vitamin D supplements a very good idea, all year round.

The overweight and obese are more prone to vitamin D deficiency – they represent 51% of the European population! The prevalence of vitamin D deficiency is 24-35% higher among the overweight and obese. It's because fat cells store vitamin D, making it less available to the body.




You might notice that not a cold goes by without you catching it. Other than that you might:

  • Feel tired,
  • Have aches in your bones and muscles,
  • Be losing hair,
  • Feel down for no reason.

All of these might mean you are lacking in vitamin D. Since a properly functioning immune system is crucial during these times, it’s very important to keep your D3 levels high.




Vitamin D has two common forms: vitamin D3 (cholecalciferol) and D2 (ergocalciferol). D3 is found in oily fish, meat and the fat in sheep’s wool. It’s also the form of vitamin D that forms in our skin with the help of sunlight.

D2 is found in certain plant sources. It also has a shorter shelf life, so if you have a bottle of it sitting around for a long time, it will inevitably lose some potency.

Your body prefers D3 because it can absorb and utilise it a lot better than D2. It stays in your blood longer, keeping your vitamin D levels elevated and stable over a period of time. In short, D3 is what your body knows, needs and works with best.

With all that in mind, we created ALL IN A DAY Vitamin D3 – the only D3 supplement you’ll ever need.
