Constant Bone and Back Pain
Vitamin D is essential for calcium absorption in your bones. Without enough of it, your bones become weak and soft — a condition called osteomalacia in adults. This manifests as a persistent, dull ache in your lower back, hips, pelvis, and legs. The pain is often mistaken for arthritis or aging, but it's actually your bones crying out for Vitamin D to help them absorb the calcium they desperately need.
