NUTRITION WHY’S # 28: WHY VITAMIN D? Vitamin D is a fat-Soluble vitamin that goes into your body fat so that overweight and obese individuals often have low blood levels of vitamin D. In some countries over 40% of people have low levels of vitamin D. You need vitamin D to absorb Calcium and to maintain normal immune function. It is so important that we make vitamin D in the skin when it is exposed to sunlight. Today many people where sunscreen or work indoors so that they are not exposed to the sun long enough for adequate vitamin D production. Vitamin D is also found in foods such as fortified dairy, fortified fruit juice, and oily fish. Vitamin D supplements are popular and while only 400 IU are needed for bone health, many people take over 1000 IU for its immune effects. The immune effects were known in the 1800’s when people with tuberculosis of the skin could be healed by being outdoors in the sun at a sanitarium. Today your best bet is a Multivitamin with D, a Calcium supplement with D and a Vitamin D capsule. You won’t get too much as long as the total vitamin D is under the upper limit of 4,000 IU per day. The body has a way of getting rid of extra vitamin D and there are controls on its activation in the liver and the kidney for calcium absorption into the blood stream. Vitamin D from sunlight or the diet goes through a two-step chemical modification. The liver forms 25-hydroxy vitamin D which is the blood level measured to determine your vitamin D status. That form is then converted to 1,25 dihydroxy vitamin D (the most active form) in the kidney under the influence of many factors. Your body and will take care of the vitamin D you make or take in the diet and supplements so you can concentrate on Balanced Nutrition and a Healthy Active Lifestyle!! #drdavidheber #vitamins #weightlossjourney #sunlight #vitamind to learn more go to www.drdavidheber.com and www.herbalifenutritioninstitute.com
