Nature Made Vitamin C 500 Mg Tablets, 250 Count, For Immune Support, Gluten Free

Nature Made Vitamin C 500 Mg Tablets, 250 Count, For Immune Support, Gluten Free is a product from Nature Made, categorized under Immune health & antioxidants in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.

62/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Manufacturing 72, Safety 65, Transparency 65, Evidence 62, Formulation 60, Sustainability 55. Scored as of 2026-08-24.

Nature Made Vitamin C 500mg is a mass-market USP-verified product — Nature Made carries USP verification on a broad SKU set, which is uncommon in supplement space. Vitamin C has modest RCT support for cold duration reduction (Hemilä 2013 Cochrane); therapeutic effect is dose-dependent above ~200mg with diminishing returns. Ascorbic acid form is fine but liposomal or Ester-C forms are gentler on stomach. Would move to Verified 70+ if the specific batch shows USP verification on this SKU (some Nature Made products but not all).

Strongest: Manufacturing at 72/100 (third-party testing, GMP compliance, and facility audit status) and Safety at 65/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Formulation at 60/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Sustainability at 55/100 (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 Verified 70+ if the specific batch shows USP verification on this SKU (some Nature Made products but not all).
