Chronic diseases like Type 2 Diabetes and those related to malabsorption, including kidney disease, Crohn’s and celiac disease greatly inhibit the body’s ability to metabolise vitamin D from food sources, researchers said.
Considered a hormone rather than a vitamin, vitamin D is produced when skin is exposed to sunlight.
Vitamin D receptors are found in virtually every cell in the human body. As a result, it plays a wide role in the body’s functions, including cell growth modulation, neuromuscular and immune function and inflammation reduction.
Symptoms for insufficient or deficient vitamin D include muscle weakness and bone fractures.
Increasing and maintaining healthy vitamin D levels can be as easy as spending 5-30 minutes in midday sun twice per week, researchers said.
