One other examine on tendon-to-bone restoration after rotator cuff surgical procedure urged that vitamin D could have a job in therapeutic after harm. (19) Vitamin D ranges in sufferers have been linked to bone and muscle therapeutic, and this examine urged it could impression tendon-to-bone as nicely. 

The outcomes point out a constructive correlation between vitamin D and muscle and bone therapeutic. Nonetheless, there must be extra analysis on its position in skeletal-tendon healing. (19)

Could Enhance Bone Well being

A evaluate of research on bone well being means that vitamin D may help folks experiencing results from the “feminine athlete triad.” (21) This refers to 3 situations that may trigger low vitality availability in folks assigned feminine at beginning, and sometimes seem collectively: disordered consuming inflicting inadequate diet, menstrual issues, and low bone mineral density. (22) 

Folks experiencing this athlete triad could profit from rising vitamin D to enhance bone mineral density and assist stop stress fractures.
