Vitamin D is a fat-soluble nutrient that plays a key role in almost all of our physiological functions. As an immune system regulator, vitamin D is absolutely vital to vibrant health. Itโs the only vitamin your body makes itself (and itโs actually a hormone!).
Although sunlight is one source of vitamin D, there are very few individuals who get enough exposure to reap the benefits adequate levels of vitamin D provide. In addition, excessive time in the sun can increase the risk of skin cancer.
Normal dosing of vitamin D depends on your blood levels and your medical history. Those with impaired digestion and absorption of fats (and thus fat-soluble vitamins) may also need sublingual forms or higher doses to gain optimal blood levels. Be sure to consult your practitioners for your unique needs.
