Here are 10 reasons why you should take vitamin D :
1. Reduction of the mortality risk: A 2008 study found that a vitamin D deficiency increased the risk of death by 26% compared to people with optimal vitamin D levels ! (1) This may be due to the fact that vitamin D can induce apoptosis therefore reducing the potential for the malignant cells to survive. (4)
2. Reduction of osteroporosis and bone fracture: It has been shown that a vitamin D and calcium supplementation decreased the risk of hip fracture up to 43%. Risk for osteoporosis increases when there is a vitamin D deficiency as it causes mineral loss in the bones like calcium. Without vitamin D, you can only absorb up to 10 to 15% of calcium.(2-4)
3. Decreased cancer risk: Studies have shown that vitamin D levels (25-OH) under 20 ng/ml has been associated with an increase of colon, prostate and breast cancer by 30 to 50% and an increased mortality rate in these cases. Vitamin D controls over 400 genes responsible for apoptosis among other things (permits the auto-destruction of cancer cells). (4-5)
4. Helps the immune system: Vitamin D is an immune system messenger. When the vitamin D levels go under 20 ng/ml, the monocytes cannot elicit an immune response. This could be the reason why black Americans, which are more proned to be vitamin D deficient because of skin color, might me more susceptible to contract a tuberculosis than white Americans. (4)
5. Decreased Hypertension risk: It has been shown that living at high altitude increases the risk of developing hypertension and heart diseases. This is due to the fact that we produce less vitamin D at high altitude. In a study of patients with hypertension who were exposed to ultraviolet radiations three times a week for 3 months, 25-hydroxyvitamin D levels increased by approximately 180% and blood pressure became normal. (4-6)
6. Decreased asthma symptoms: Asthma is a chronic disease from which the primary cause is still unknown nowadays, but we know that it is a myriad of complex interactions involving many genes and environmental factors. It has been shown that vitamin D promotes the regulatory T cells which plays a major role in the immune response. They also permit the inhibition of T-helper-2 immune responses which are often responsible for many allergic diseases and asthma. (7-8)
7. Decreased multiple sclerosis risk: Studies show that among white men and women, for every 20 ng/ml of 25-(OH) D above 24 ng/ml, there is a 41% reduction of multiple sclerosis risk. (4)
8. Prevent muscle mass and strength loss: It has been demonstrated that low levels of vitamin D, which increases parathyroid hormone secretion would have a direct impact on raising the levels of cytokines IL-6. Studies have shown that elevated levels of cytokines IL-6 is linked to muscle mass and strength loss. That may be due to the fact that vitamin D prevents sarcopenia which is a degenerative loss of strength and skeletal muscle mass associated with aging. (10)
9. Prevents insulin resistance and diabete type 1: A vitamin D deficiency reduces the insulin production, causes an insulin resistance and is directly linked to diabete. In a study with 10 366 children in Finland, it has been demonstrated that after taking 2 000 IU of vitamin D3 daily for their first year of life, there was a reduction of 80% in the development of diabete type 1. Another study showed that vitamin D supplementation combined with calcium in women have reduced the risk for diabete type 2 by 33%. (4-9)
10. The majority of the population in North America is vitamin D deficient: Studies shows that 90% of pigmented people (Blacks, Asians, Hispanics) and 75% of white people have insufficient levels of vitamin D in North America. (11) Insufficient levels means below 30 ng/ml. According to the world experts, around 98% of the population do not have optimal levels of vitamin D in their blood.
To get your vitamin D to optimal levels, I recommend you to take at least 5 000 IU daily of vitamin D3. I suggest you D3 Liquid by Metagenics which is an excellent quality product that I use extensively. Come get your vitamin D3 supplement today at Axellite Comprehensive Health !
