How it works
Vitamin D receptors are expressed in the brain, immune system, and mitochondria. Deficiency impairs energy metabolism, immune regulation, and neuromuscular function.
Test blood levels before supplementing β target 25(OH)D of 50β80 nmol/L. Doses above 4000 IU/day require monitoring. Take D3 with K2 if supplementing long-term.
Multiple RCTs show significant improvement in fatigue scores with vitamin D correction in deficient patients. High prevalence of deficiency in ME/CFS populations.

βSome improvement but not as dramatic as I hoped. Might need longer to see full benefit. Still continuing.β
