What is Vitamin D3?

Vitamin D is synthesised in the skin via exposure to sunlight hence it is often referred to as ‘the sunshine vitamin’. There are two forms of Vitamin D; D2 and D3. Research tends to show the D3 version as being far superior to the D2 version and our nutrition experts insist on using vitamin D3 in all Healthspan formulations as this is the form that is naturally found in the human body.

Vitamin D benefits

As we age, we are thought to be more at risk of vitamin D deficiency because our skin's ability to convert vitamin D into its active form decreases.

Vitamin D has received extensive coverage in the media recently and new research shows that optimum intake levels may be far higher than originally thought. New Public Health England report recommends vitamin D supplements should be taking by all. 

The benefits are wide and varied, including its role in the maintenance of normal muscle function and in supporting a healthy immune system. However, vitamin D is probably best known for the role it plays in supporting healthy bones and teeth as it aids in the efficient absorption of calcium. 

Each Super Strength tablet contains 25µg (1,000iu) of vitamin D3 in its natural form.
