3. You have joint pain
If you have joint pain your doctor probably prescribed you vitamin D supplements. When you have low vitamin D levels, your joints hurt and this is actually your body’s response to inflammation. Taking vitamin D supplements can reduce the pain, but we also recommend you to spend as little as 15 minutes a day outdoors.
Also, “if you are noticing more pains in general, and you have been less active, you may be able to feel better by exercising and releasing some endorphins (chemicals manufactured by your body to minimize the pain) into your bloodstream,” says Dr. Larry Burchett.
