Vitamin D, Building Your Immune System with the Right Tools

What tools do you have in your toolkit to fight off colds, flu and infections? Is it working? Or are you still fighting cold after cold? Are you wasting money on vitamins and “immune boosting” products? Chances are if you’ve been sick this year, you may not be supplying your immune system with the right tools.
Over the last 5 year, no other nutrient or drug has gained more scientific credibility than vitamin D. Insufficient vitamin D is linked to virtually every age-related disorder including cancer, vascular disease, autoimmune diseases, depression, chronic fatigue and chronic pain/inflammation. Adults (and children) with higher vitamin D levels contract substantially fewer cold, flu, and other viral infections.
Studies show 50-85% of the general population is currently Vitamin D deficient. In fact, a startling 36% of the general population has vitamin D levels below 20 ng/mL which may represent the world’s leading cause of unnecessary disease and death.
How do I know if I’m Vitamin D deficient?
See your doctor for a simple blood test to check your vitamin D levels. Based on recent and conclusive published studies, the new minimum target level for optimal disease prevention is over 50 ng/mL of 25-hydroxy-vitamin D.
How much Vitamin D?
If you are severely deficient, your doctor may prescribe a 7,000-10,000 IU vitamin D3 daily for 3 months (Or weekly doses of 50,000-60,000 IU). Currently the daily recommended amount is only 400 IU. There is some debate over how much vitamin D3 we should be taking. Some doctors are pushing to change the daily recommendation to 1,000-2,000 IU per day.
Dr. John Cannell, the president of The Vitamin D Council, a non-profit group that advocates higher vitamin D intake. According to Dr. Cannell, adults need to take 5,000 IU a day of vitamin D3 to put the vast majority of them (97.5%) above the 50 ng/mL level. Dr. Cannell says that optimal doses for adults are between 4,600 and 10,000 IU, with persuasive evidence that 10,000 IU a day of supplemental vitamin D3 is not toxic. To answer the question as to exactly how much vitamin D3 an individual needs requires a blood test.
Most commercial multi-vitamins only have 400 IU of vitamin D. Some of the better vitamin companies have increased the dosage to 2,000 IU. In another surprising revelation, scientists have discovered that high-dose vitamin A antagonizes the beneficial action of vitamin D3 in the body. This finding might explain why certain studies of people using commercial multivitamins (that contain too much vitamin A and woefully inadequate vitamin D) have failed to yield expected health benefits. Life Extension foundation and the Vitamin D Council recommend taking vitamin D3 separate from a multi-vitamin.
Human toxicity may occur after chronic daily consumption of approximately 40,000 IU/day of D3. Vitamin D hypersensitivity syndromes are often mistaken for vitamin D toxicity. Those with a rare disorder called sarcoidosis, severe renal impairment, primary hyperparathyroidism, or any condition resulting in an elevated calcium level in the blood should consult with their physician before taking vitamin D supplements.
My Personal Vitamin D Experience
2 1/2 years ago after reading some of the vitamin D reports, I decided to add vitamin D3 to my vitamin regimen. My 2-A-Day multi vitamin had 2,000 IU. I then added a 1,000 IU vitamin D3 (I may have forgotten to take it a couple of days a week).  After 6 months I caught 4 colds and the flu. I decided to see my doctor; I was tired of catching every cold that walked past me and my energy was zapped. She ran several tests, everything was OK – except my vitamin D levels were low - around 40. She suggested taking 5,000 IU in addition to my multi-vitamin.  It can take 3 months or more to bring your Vitamin D levels up to a healthy level.  Taking large doses upon the onset of a cold may not help to kick the illness. But it may help if you've been inconsistant with taking your vitamins. It seems when I'm taking my D daily, I feel great. If I start slacking and only taking them once or twice per week, I'm putting myself at risk for possibly getting sick. If I start to feel a cold coming on, I immediatly take 10,000 IU of vitamin D. Then I take 4,000 MG of Buffered Vitamin C, 4 times per day with food until i feel normal again. Over the last 2 years, I've felt about 4 colds coming on. My asthma usually acts up and I might feel tired. I have not felt congested, had cough or any other cold symptom.
