Vitamin D and mucosal immune function

Vitamin D is important for mucosal immune function. This means it is important for the health of the entire digestive tract from the mouth, over the stomach, to the colon. Try getting your vitamin D levels to 50-70 ng/ml and see if your lips get better. Supplements might not have the same results as getting the Vitamin D from sun exposure. See if a local pharmacy offers a cheap instant test.
