Today, we’re going to talk about the most important vitamin: vitamin D! There is a lot of misinformation about vitamin D. Vitamin D blood levels are not very well correlated with the vitamin D inside your cells. It’s also virtually impossible to get enough vitamin D from food. There are 2 different systems for vitamin D: one for calcium and bone and one for all the non-calcium functions of vitamin D, including the immune system, prostate, skin, gut, brain, and muscles. Hardly any of the vitamin D in your blood goes into this second system! Most research on vitamin D involves the calcium system of vitamin D and only 600 to 800 IU. This amount may be sufficient for bone health but not for the other functions of vitamin D. Barriers to vitamin D absorption that can lead to low vitamin D include the following: •Air pollution •Sunscreen/Avoiding the sun •Gut inflammation •Magnesium deficiency •Genetics •Latitude/Altitude/Season •Aging •Insulin resistance •Low cholesterol •No gallbladder A healthy person needs around 10,000 IU of vitamin D3 each day.
