Another Vitamin D Win

I read and copied this off the modern forager blog...if I can get as much information on Vitamin D to the public it will be a victory!

What Does Vitamin D Have To Do With Your Back Pain?

There are a number of reasons for why vitamin D deficiency can cause chronic pain.
1. Vitamin D deficiency causes a reduction in calcium absorption.
2. Production of parathyroid hormone is increased to maintain blood calcium levels
3. Parathyroid hormone results in increased urinary excretion of phosphorus, which leads to hypophosphatemia.
4. Insufficient calcium phosphate results in deposition of unmineralized collagen matrix on the endosteum (inside) and periosteum (outside) of bones.
5. When the collagen matrix hydrates and swells, it compresses the sensory-innervated periosteum, resulting in pain.
