Bone and back pain

Vitamin D promotes bone health by improving calcium absorption in the body. As a result, bone and lower back pain may be symptoms of low vitamin D levels. In one study of 98 adults with lower back pain, lower levels of vitamin D were linked to more severe pain. A large research review, however, discovered that this association was inconsistent across other similar studies.

Vitamin D is essential for bone and muscle function and has anti-inflammatory properties. As a result, vitamin D can help relieve joint pain, especially when inflammation is the cause. A meta-analysis of 81 studies also discovered that people with arthritis, muscle pain, and chronic widespread pain had lower levels of vitamin D than those who did not have these conditions. According to a 2012 study, vitamin D deficiency may be a risk factor for the onset of inflammatory diseases and may worsen their severity.
