USP verified for potency and purity. D3 (cholecalciferol) is the form your body makes from sun. Single ingredient with no fillers.
Quality & Materials
Vitamin D3 in organic olive oil base. No soy, gluten, or artificial additives.
Evidence & Testing
USP verified. D3 shown to be 87% more effective than D2 in raising blood levels.
Brand Transparency
FDA-registered facility. USP verification means third-party testing of every batch.
Value Assessment
$15 for 360 soft gels (1-year supply). Exceptional value at $0.04/day.
Why Not Alternatives?
Many D supplements use D2 (ergocalciferol) which is less effective. Carlson's USP verification is rare in the category.
