What is Vitamin D3?

There are two forms of Vitamin D: D2 and D3. Vitamin D2 is made synthetically from fungus and plant matter. Vitamin D3 (also known as cholecalciferol) is the same type that is made by the body via exposure to sunlight, hence the term 'the sunshine vitamin'. Research tends to show the D3 version as being far superior to the D2 version. 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.

What is in each Tablet?

Each Super Strength tablet contains our experts' optimum recommendation of 25mcg (1,000iu) of vitamin D3 in its natural form.

Vitamin D benefits

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. The benefits are wide and varied and include contribution to the maintenance of normal bones and teeth; contribution to the maintenance of normal muscle function; contribution to the normal function of the immune system and healthy inflammatory response, and contribution to the absorption of calcium and phosphorus and the maintenance of normal blood calcium concentrations.

I am happy to buy from Healthspan. I have noticed that over the last 2 years you have improved a lot the delivery times to Greece.
You' ve also got EXCELLENT customer service on calls and emails.
I am probably one of the most satisfied customers of yours.
Keep the good work!
I always recommend you to my Greek friends.
