Frequently asked questions
Why take Vitamin D3 Oil?
Vitamin D3 Oil supports bone health, immune function, and mood regulation.
How much vitamin D do I need?
Most adults benefit from 2000-4000 IU daily, depending on blood levels.
When should I take vitamin D?
Take with your largest meal containing fat for best absorption.
Can I take too much vitamin D?
Yes, vitamin D is fat-soluble. Get your levels tested and work with a practitioner to find your optimal dose.
Why is vitamin D paired with K2?
Vitamin K2 helps direct calcium to bones rather than arteries. They work synergistically for bone and cardiovascular health.
How do I know if I am deficient?
A blood test is the only reliable way to know. Symptoms of deficiency include fatigue, low mood, frequent illness, and bone pain.
