Vitamin D is everywhere these days, and in more ways than one. It is literally all around us, as our main source of vitamin D comes from exposure to the sun. We also get some vitamin D from the supplementation of milk and some cereals. Vitamin D is crucial for bone health in children and adults, and treating low levels of vitamin D with oral vitamin D supplements can prevent bone diseases such as rickets and osteoporosis in susceptible individuals. Vitamin D also has other important roles in the body, including regulating cell growth, immune function, and glucose metabolism. A vitamin D level below 20 ng/mL is considered to be low.
The recommended daily amount of vitamin D is 600 IU per day for adults. The Endocrine Society recommends extra vitamin D for certain groups, including children, adults over the age of 75, pregnant women, and people with prediabetes. Studies have shown that if you have prediabetes, taking vitamin D can actually reduce your risk of developing diabetes in the future!
It’s important to note that too much vitamin D can be harmful, so talk to your doctor about what the optimal level is for you.
