Vitamin D3 and K2 2500 IU (Pot of 90 Capsules)
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.
Many of you may not be aware of the great importance of Vitamin K2. It is only in the last 5 years that the importance of Vitamin K has become apparent. There are 2 important forms of Vitamin K, Vitamin K1 and Vitamin K2. K1 activates special proteins that help the blood to clot. These are found in green leafy vegetables. K2 activates 2 important proteins, one of which takes the calcium into the bones and the teeth and one which escorts calcium out of the soft tissues such as the arteries. Very little K1 is converted to K2 and it is essential that K2 is taken in the diet or through supplementation. K2 is found in the yolk of eggs, the fat of meat, in butter and in a fermented soya product known as Natto.
The main reason for Vitamin K2 deficiency is that our food just does not contain enough. Most dairy and meat cattle are grain fed, either partially or totally. Most chickens do not roam free to eat grass and only grass fed animals have sufficient chlorophyll levels to convert to Vitamin K2. Another reason for K2 deficiency is the introduction of Trans fats in margarine and butter substitutes. These contain a mutated form of vitamin K1, which is created when vitamin K1 rich plant oils are synthetically hydrogenated. Researchers have shown that tissue levels of K2 are lower when DHP is high. There are 2 forms of Vitamin K, MK4 and MK7. MK7 can last in the body for 36 hours, much longer than MK4 so Metabolics uses MK7.
Vitamin K2 contributes to the normal maintenance of bones.
