How does Vitamin D affect the immune system? Vitamin D receptors have been found present in the bone, breast, gut, prostrate, and lymphocytes. Over the years studies have shown that this hormone is found in high concentrations in the T-lymphocytes and macrophages. The lymphocytic cells and macrophages are our major protectors against foreign invaders such as viruses and bacteria. For prevention against influenza, Dr. John Cannell suggests adults should take 5,000 IU Daily of Vitamin D, and children should take 1,000 IU’s per 25 pounds of body weight.
So while many contemplate on whether or not to get a flu vaccine, increasing Vitamin D levels can be a safe and natural alternative to help improve your immune system during the flu season. If you would like to check the levels of Vitamin D in your body (you may be surprised by the results!), there is a lab test your doctor can take. The best test is a serum test checking for levels of 25(OH)D- in your blood. Optimal levels are between 40-65 ng/ml (50-80 ng/ml). Remember to check with your health care provider before trying any supplementation or new medications.
