Vitamin D is actually a hormone. It enables the absorption of Calcium and Phosphorus from the intestines and regulates gene expression in over 2000 genes of our 30,000 genes.
Vitamin D3 is naturally produced in humans in the skin when UVB light hits the skin and converts cholesterol to previtamin D, which is then converted to D3 (cholecalciferol) in the liver.
It is estimated that 20 minutes of sun exposure produce 20,000 IU of Vitamin D3 and we know there are Vitamin D3 receptors in most cells in the body.
Vitamin D is important for:
- Maintaining healthy bones and teeth.
- Absorbing calcium and phosphorus, all important in bone health.
- Supporting normal cell division.
- Helping to keep the immune system functioning normally, including the inflammatory response to wounds and infection
- Normal muscle activity. There are a number of important factors that affect our body’s Vitamin D production, these include:
- Latitude– The further north that you live, the less intense the UV exposure as the suns rays have further to travel as the sun is lower. If you live above 35 degrees latitude you will not be able to make Vitamin D from the sun from November – March.
- Season– the season of the year affects the angle that the suns rays hit the earth, and that angle affects how much UVB gets to the skin. This depends where you live in the world. Generally at the end of the summer peoples Vitamin D levels are greater than at the end of the winter. Vitamin D producing days are less the further North you go.
- Altitude– The higher the altitude the more Vitamin D you can make from exposure to UVB rays. At lower altitudes the atmosphere absorbs the suns rays.
- Time of Day– When the sun is directly overhead the greater the exposure to UVB there is.
- Air Pollution– Pollution can block UVB rays.
- Cloud cover– UVB light is 50% less under cloud cover.
- Sunscreen– The higher the SPF factor the less exposure to UVB. An SPF 8 prevents 92% production of Vitamin D in the skin and an SPF 15 reduces it by 99%.
- Melanin content of the skin.Skin types are classified 1-6. Type 1 is fair skinned and always burns, while Type 6 is dark skinned and never burns. However dark skinned people require up to 10x the amount of sun as light skinned people. It is harder for the sun to penetrate the skin and manufacture Vitamin D.
- Age– Older people need more sun exposure to make Vitamin D. As we age we produce less Vitamin D precursor and therefore less Vitamin D. An elderly person will produce 75% less than a young person when exposed for the same length of time, and elderly people tend to spend less time in the sun.
- Weight– The fatter you are the less Vitamin D you will have available, as the fat cells store it, making less available for tissues and organs
- Clothing cover – The greater the skin covering with clothing, the less exposure to UVB.
