NovaFerrum liquid iron — polysaccharide-iron complex form. Iron polysaccharide has better GI tolerance than ferrous sulfate at comparable elemental iron doses (Powers 2017). Liquid delivery aids adherence and allows flexible dosing. 125 mg elemental iron per dose is at the upper end of therapeutic range for adult iron-deficiency treatment. Held below Verified by (1) iron supplementation without prior serum ferritin/iron panel workup is a safety concern — the label warning language could be stronger; (2) sold via pharmacy reseller; (3) 125mg is above what's needed for repletion in most cases and could cause over-supplementation risk. Would move to Verified 70+ with prominent 'confirm iron deficiency via lab test first' warning + lower-dose SKU option.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

Strongest: Formulation at 75/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Evidence at 72/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Safety at 62/100 (adverse-event profile, interaction risk, and dose ceiling) 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.
