Vitamin D supplements for bone health and immunity
Based on our analysis of 4,418 vitamin d products, Vegan D3 Spray 2,000 IU Vanilla Bean Flavor ranks #1 with a SupplementScore of 70/100. Scores are based on label quality — dosage transparency, formulation cleanliness, and ingredient disclosure.
Every product is scored algorithmically using data from the NIH Dietary Supplement Label Database. The SupplementScore evaluates dosage transparency (35 pts), label completeness (25 pts), formulation cleanliness (25 pts), and ingredient profile (15 pts).
No. The score reflects label quality — how transparent and clean the product label is — not clinical efficacy, bioavailability, or safety. A higher score means better label practices, not guaranteed results.
