What is Vitamin D3 and Why Do We Need It

Vitamin D3, or the Sunshine Vitamin, isn’t a vitamin at all. It’s actually a steroid with hormone-like activity. Unlike other vitamins which our body obtains from food, Vitamin D3 is synthesized in our skin when exposed to sunlight. Vitamin D3’s most well-known benefit is that it facilitates calcium, magnesium and phosphate absorption which are responsible for growth and maintenance of bones.  Vitamin D3 deficiency can lead to brittle bones or osteomalacia. 

Further studies have revealed even more positive effects of Vitamin D3 which include:

  • Lowering the risk of cancer with the strongest evidence for colorectal cancer 
  • Lowering the risk of heart disease. It’s been proven that Vitamin D3 helps suppress inflammation of the heart and blood-vessels
  • Decreases chances of getting age-associated blood pressure fluctuations
  • Recent studies have found that chronically inadequate Vitamin D3 intake may play a significant role in the onset of Parkinson’s disease in elderly 
  • Lowers risk of autoimmune diseases such as multiple sclerosis (MS), type 1 diabetes, rheumatoid arthritis, and autoimmune thyroid disease etc. 

Getting at least 5-10 minutes a couple of times a week is usually sufficient for most people to make the RDI of 5mcg-15mcg (200IU-600IU).

In Australia and New Zealand, most of the population gets its Vitamin D3 from sunlight instead of dietary sources. That makes it particularly hard to reach the RDI in winters. Data shows that as many as 31% of adults in this region suffer from Vitamin D3 deficiency.  However, deficiency is not just a phenomena in the  AUS/NZ region.  Vitamin D3 deficiency is a worldwide public health concern with over a billion people affected.
