Vitamin D (Correct Deficiency)
for Chronic Fatigue
Vitamin D deficiency is common and undertreated in fatigue conditions. Correcting deficiency consistently improves fatigue, mood, and immune function.
How it works
Vitamin D receptors are expressed in the brain, immune system, and mitochondria. Deficiency impairs energy metabolism, immune regulation, and neuromuscular function.
What to watch for
Test blood levels before supplementing โ target 25(OH)D of 50โ80 nmol/L. Doses above 4000 IU/day require monitoring. Take D3 with K2 if supplementing long-term.
