Vitamin D - Essential to Longevity
Be aware that while sunscreens protect our skin, they also prevent the manufacture of vitamin D through the skin.
Research shows that a vitamin D deficiency can be very destructive. Any flaw in the liver or kidney organs may have an effect on the accessibility of active vitamin D in the body. In addition, the brain is a critical organ in the body and a lack of vitamin D results in a feeling of tiredness, a loss of enthusiasm, and progressive depression similar to SAD. It is known that serotonin, a neurotransmitter essential to brain function, influences positive behavior and mood. This is a primary function of vitamin D.
Vitamin D is misnamed because it is more of a hormone than a vitamin; it qualifies as prohormone. It belongs to a group called sterols, which are made from cholesterol, which includes cortisol, estrogen, testosterone and progesterone. This family of hormones is related to many other hormones, vitamins, and minerals. For example, vitamin D is predominantly in relation with vitamin A, calcium, magnesium, and omega-3.
Studies has shown a long list of benefits of vitamin D to promote optimal health. Vitamin D helps battle fatigue and seasonal depression. It plays a very significant role in averting arthritic and joint pain. It protects us from heart disease and vascular issues. It advances insulin action and may prevent type II diabetes. It supports the proper performance of the immune system and is especially critical in very young children to help build an successful defense system. It plays a principal role in cell growth and may prevent the development of many types of cancers. Researchers at the Mayo Clinic found that 93% of patients with severe pain in the skeleton and muscles, also had a blood level of vitamin D which was too low.
All these symptoms and diseases can be associated to a vitamin D deficiency and may vanish or be improved by increasing your blood levels of vitamin D: depression (including seasonal affective disorder), fibromyalgia, parkinson''s disease, alzheimer''s disease, arthritis (all joint disorders), osteoporosis, gingivitis and other gum diseases, dental problems, obesity, type II diabetes, heart disease, metabolic syndrome, autoimmune diseases, and cancers.
It is impossible to get the daily requirement of vitamin D from food. Wild salmon from Alaska is a good source of vitamin D, but it is still insufficient, unless the fish to consumed on a daily basis. Vitamin D is produced naturally by the body when there is exposure to sunlight (the best source of vitamin D). For a variety of reasons (including geographic location and season), getting sufficient natural sunlight can became a difficulty for the vast majority of people living north or south of the equator.
