This study suggests vitamin D and inflammation markers may be linked to muscle health with age.
People with sarcopenia (age-related loss of muscle mass and strength) tended to have higher inflammation markers like CRP and lower vitamin D. Pooling 43 studies from the past 15 years, researchers also looked at sarcopenic obesity, where muscle loss and excess fat show up together. For anyone tracking blood work as they age, inflammation and vitamin D may offer early clues about muscle health. The studies were mostly one-time snapshots that can't show cause, and some results were puzzling, like higher HDL cholesterol in sarcopenia.
