Observational studies support an association between higher serum 25(OH)D levels and a lower risk of CVD incidence and mortality. Vitamin D might be involved in the pathophysiology of type 2 diabetes through its effects on glucose metabolism and insulin signaling as well as its ability to reduce inflammation and improve pancreatic beta-cell function [1443,145]. hello pbhealth my story is also similar to you ... when i start feeling better out of nowhere i get fatigue and no one can understand that... doctors were of no help .. i dont know what to do ... have you recovered yet or still struggling.
