Vitamin D is a type of cholesterol. It’s made in the skin in response to the Sun. Deficiencies which are quite common can lead to autoimmune issues, chronic fatigue, depression, muscle aches, frequent colds, flues and osteoporosis.

And, if your bones fracture or break easily, you could be missing this vital nutrient. Typically deficiencies are linked to a lack of solar exposure. While folks who avoid the Sun or use lots of sunscreen can take supplemental capsules, because vitamin D from supplements, as well as from sunshine, is inactive, it needs to be turned on in the liver and kidney. You could have a functional vitamin D deficiency, even if you’re supplementing or out of the Sun.

If you are dealing with poor kidney function or have a fatty liver, in addition to getting regular sun exposure or supplementing, make sure you’re taking care of these critical organs by staying away from problem foods, as well as avoiding processed carbs and excessive sugar intake, both important strategies for maintaining liver and kidney health.
