Why Not Just Buy D3 at CVS?+
Standard pharmacy D3 is 400–1,000 IU — a dosage set in the 1940s to prevent rickets in children. The research on D3's effect on serotonin, anxiety, and neurological function uses 2,000 IU daily minimum. Most pharmacy D3 also uses D2, which is 87% less effective at raising blood levels than the D3 (cholecalciferol) in Rootvara. Same vitamin name. Completely different effect.
Why Cholecalciferol D3?+
D3 is a neurosteroid — it crosses the blood-brain barrier and binds directly to receptors in your amygdala and hippocampus, the regions that regulate anxiety and fear response. It directly supports serotonin synthesis — the same pathway antidepressants target. When D3 is deficient, your brain cannot regulate anxiety signals properly. Restoring it addresses the source, not just the symptoms.

Why Rootvara
Why Not Just Buy It at CVS?
The dose matters more than most people realise. 400 IU was set in the 1940s for rickets. 2,000 IU is what neurological research actually uses.

Formula
Why Cholecalciferol —
Not Just Any Vitamin D
Not Just Any Vitamin D
Most D3 supplements use the wrong form at the wrong dose. Here's what makes Rootvara different — and why it actually works for anxiety and mood.
☀️
Cholecalciferol (D3) — 2,000 IU
The only form that crosses the blood-brain barrier and directly activates receptors in your amygdala — the brain region that controls fear and anxiety responses. Regulates serotonin synthesis. 87% more effective than D2 at raising blood levels. This is what your skin makes from sunlight. Modern indoor life stopped giving it to you.

FAQ
Have Questions? We Have Answers.
Can't I just buy Vitamin D3 at CVS or Walmart?+
You can — but the dose matters more than most people realise. Standard pharmacy D3 is 400–1,000 IU, a dosage set in the 1940s to prevent rickets in children. The research on D3's effect on serotonin, anxiety, and neurological function uses 2,000 IU daily minimum. You'd need to take 2–5 pharmacy capsules every day to match Rootvara's dose. Most cheap D3 also uses D2, which is 87% less effective at raising blood levels than the D3 (cholecalciferol) in Rootvara. Same vitamin name. Completely different result.
How long until I notice results?+
Most customers notice sleep improving first — usually within 2–3 weeks. The anxiety and mood improvements typically follow around weeks 4–6. The full effect, where you consistently feel like yourself again, usually arrives around weeks 6–10. D3 works by restoring levels depleted over months or years — it takes consistent daily use to fully rebuild. The 2-bottle supply covers the full window and is our most popular for this reason.
Is this a subscription? Will I be auto-charged?+
No. Every order is a one-time purchase. No subscription, no auto-billing, no recurring charges. You order when you're ready.
What's your refund policy?+
30-day satisfaction guarantee. If you don't feel a meaningful improvement within 30 days, contact us at support@rootvara.com and we'll sort it out — no questions asked, no return needed.
Why does D3 affect anxiety and mood?+
D3 (cholecalciferol) is technically a neurosteroid, not just a vitamin. It crosses the blood-brain barrier and binds directly to receptors in the amygdala and hippocampus — the regions responsible for fear response and emotional regulation. It also directly supports serotonin synthesis — the same chemical pathway that antidepressants are designed to target. When D3 is deficient, your brain's ability to regulate anxiety signals is genuinely impaired. Restoring it addresses the neurological root, not just the symptoms.
Can I take this with other supplements or medication?+
D3 at 2,000 IU pairs well with Magnesium and Vitamin K2. It's safe alongside most supplements. If you're on prescription medication — especially for thyroid, kidney, or heart conditions — consult your doctor first.
How soon will my order arrive?+
Ships from our US warehouse. Standard delivery 3–5 business days. Free shipping on orders $60+. You'll receive a tracking email once shipped.
