VITAMIN D & IMMUNE FUNCTION: Vitamin D is a fat soluble vitamin/ steroid hormone that is essential for bone metabolism and calcium function, modulation of cell growth, neuromuscular function and immune function (including autoimmune issues). It not only helps to boost both innate and adaptive immune function, it is an immune modulator (balance) and seems likely to help dampen cytokine storms.
It is known than many Americans, 40-80% are vitamin D deficient. Deficiency is worse in people who are older, darker skin, stay indoors, dwell in cities, live up north, have kidney and liver problems, wear a lot of sun screen, etc. Most people will need to supplement because there are few foods with good natural levels of vitamin D. Also, it is important to spend some time (i.e.15 minutes) exposing most of your skin to the sun without sunscreen. Ultraviolet light converts the vitamin D precursor (from cholesterol) in your skin so that it can proceed for processing to your liver and finally kidneys to become active D3.
There are varying opinions about what dose to use. Numbers vary from 2000IU to 4000IU daily. Some recommend higher doses such as 5000IU or more to help optimize blood levels. Blood levels of 30ng/ml are considered acceptable by some, while other experts suggest 50ng/ml or even higher according to studies. While vitamin D3 is actually a hormone and does have toxic effects when taken in high doses, reports show dangerous levels are from consumption of 100,000IU taken daily for several weeks to months. OBVIOUSLY DON'T TAKE THAT MUCH!!! Finally, it should be noted that it takes time to optimize one's vitamin D levels and that vitamin D needs to be taken daily or weekly to be of help. Monthly bolus doses are significantly less effective. Vitamin D is better absorbed when taken with dietary fats and other fat soluble vitamins.
Get tested and see what your numbers are. (Call us if you want us to order for you.)
VITAMIN A is another great immune helper among other things. For example, vitamin A and D have been shown to be effective as nutritional support during a measles infection. Miller's review book includes several research summaries for measles nutrition. VITAMIN E is another powerful immune supporter. VITAMIN K is also important for immune health and the blood. Deficiency of Vitamin K leads to less protein S and more thrombosis (blood clotting). Low Vitamin K also leads to failure of elastic fibers in the blood vessels leading to desmosins and calcification of the blood vessels with resulting fibrosis (scaring).
