Vitamin D is good for your bones because it helps your body soak up calcium. If you don’t have enough vitamin D, you might feel pain in your bones and lower back.A study in 2018 looked at 81 other studies and found that people with arthritis, muscle pain, and ongoing body pain usually had less vitamin D than those without these issues.Also, in 2018, a study with 98 adults who had lower back pain discovered that those with lower levels of vitamin D tended to have more intense pain. However, in 2017, a big study found that not all studies agreed on this connection between vitamin D and back pain.Regular monitoring of vitamin D levels and ensuring sufficient intake through sunlight exposure, diet, or supplements can contribute significantly to overall health and prevent a range of potential health complications.
