Vitamin D isn’t just for bones, it’s foundational for your entire body.
It supports your immune system, mood, inflammation balance, and overall health. The problem? Many people are technically “within range” but still not at optimal levels.
Most functional medicine practitioners recommend vitamin D levels between **50–80 ng/mL** for optimal health not just the bare minimum.
Low vitamin D can show up as fatigue, frequent illness, muscle weakness, low mood, or even hair thinning.
So how do you improve it?
Start simple:
Get regular sunlight on your skin
Eat vitamin D-rich foods like fatty fish and egg yolks
Supplement with vitamin D3 (ideally with K2 when needed)
And most importantly **test, don’t guess**.
Small daily habits can make a big difference in your long-term health.
