Increasing evidence also reveal that insufficient serum vitamin D levels also result in poor muscle health with such individuals having a compromised muscle building potential (4 times slower muscle building).\n\nMuscle health is a critical component of a post-surgical patient recovery, with impaired muscle function leading to reduced functional ability, resulting in a poorer quality of life. Poor muscle health also has negative repercussion on survivability, with reduced overall, and disease-specific survival, especially shown in cancer patients.
