Nutraxin Vitamin D3 Supplement, 120-Count Tablets - High-Potency Vitamin D3 for Bone Health & Immune Support

Nutraxin Vitamin D3 Supplement, 120-Count Tablets - High-Potency Vitamin D3 for Bone Health & Immune Support, categorized under Vitamins & foundational micronutrients in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.

56/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Evidence 68, Safety 60, Manufacturing 55, Transparency 55, Formulation 52, Sustainability 48. Scored as of 2026-08-24.

Nutraxin D3 has solid underlying evidence for the active — vitamin D3 has extensive RCT support for immune (Martineau 2017 respiratory infection meta-analysis) and bone outcomes (Bischoff-Ferrari 2009). The formulation concern is that D3 is fat-soluble and works best in oil-based softgels or drops rather than dry tablets, where absorption is significantly lower unless taken with a fatty meal (Dawson-Hughes 2013). 'High potency' isn't dose-specific on the title, so we can't verify whether it hits the 1000-4000 IU/day range that most clinicians target. Would move to Standard-high 62+ if converted to a softgel/liquid format with named IU per serving.

Strongest: Evidence at 68/100 (quality of published RCT support for the active ingredients at the label dose) and Safety at 60/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Formulation at 52/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Sustainability at 48/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.

No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.

Would move to Standard-high 62+ if converted to a softgel/liquid format with named IU per serving.
