Vitamin D3

Without sufficient vitamin D3 levels we cannot expect to be healthy and stay healthy.

What is Vitamin D3?

Vitamin D3 is not actually a vitamin but a hormone (it was wrongly named in times gone by), and is extremely important to health and everyone should consider taking this supplement if there is a deficiency. Nearly everyone is deficient in vitamin D3, even those living in warmer climates – be sure to get your vitamin D3 levels tested.

What does Vitamin D3 do?

Vitamin D3 is well known for its role in bone health, facilitating the absorption of calcium from the small intestine.

When there is insufficient vitamin D3, calcium cannot be integrated into the bones and this is where the association with osteoporosis and hip fractures come in. Apart from bone health vitamin D3 plays a host of other very important roles in the body. Below levels of optimal vitamin D3 has been linked to nearly every age-related disorder in the body, including that of cancer, chronic inflammation, Alzheimer’s, and vascular disease. Vitamin D3 is vital for our body and its defence mechanism, the immune system. There is no way we can be healthy if our immune system is down.

Why is Vitamin D3 so important?

Vitamin D3 turns genes on and off – this is one of the reasons it is so critical to our health. It affects at least 200 genes, some of these genes regulate cancer cell growth and differentiation, protecting us against cancers such as breast, colon, skin and prostate.

When vitamin D3 levels are at optimal, we have a significantly reduced risk of developing many cancers, including the aforementioned, along with:

  • ovary,
  • cervix,
  • oesophagus,
  • pancreas,
  • uterus,
  • rectum,
  • bladder,
  • lung,
  • and kidney.


Vitamin D3 levels must be at optimal and not just normal to reap these benefits. It is important to get them checked by a doctor practising restorative medicine. It is only sensible to protect ourselves and supplement with vitamin D3, if there is a deficiency, to prevent health problems that could occur later in life.

Without sufficient vitamin D3 levels we cannot expect to be healthy and stay healthy.
