View ReportHow We Chose
To select the best Vitamin D supplements, we looked at several criteria:
- Third-party testing: We prioritized brands that are tested by independent organizations like USP, NSF, or Labdoor.
- Ingredients: We searched for products free of artificial colors, flavors, and high-fructose corn syrup.
- Bioavailability: We focused on Vitamin D3 (cholecalciferol), which is more effective at raising blood levels than Vitamin D2.
