Why this scored 86/100
[Rescored via evidence crawl] Previous score undefined → new 86. Evidence found: D'Adamo CR, Novick JS, Feinberg TM, Dawson VJ, Miller LE. A food-derived dietary supplement containing a low dose of iron improved markers of iron status among nonanemic iron-deficient women. J Am Coll Nutr. 2018;37(4):342-349. DOI:10.1080/07315724.2018.1427158. PMID:29533710. | Milman N, et al. J Perinat Med. 2014;42(2):197-206. | MegaFood B Corp Certification, glyphosate residue-free certification, Non-GMO Project Verified.. Rationale: The vegan version delivers the exact same 26 mg iron + vitamin C + folate + B12 formula that was tested in D'Adamo 2018 - the only difference is the capsule shell material. So the TIER-A brand-anchor RCT applies. Combined with third-party sustainability certifications and the fact that the vegan constituency is often the population most at risk for iron deficiency, this SKU deserves Elite recognition. +10 uplift to 86 Elite. Held below 90 for the same reasons as the flagship: absence of NSF/USP facility certification layered on top of the trial, and iron supplementation still requires prior blood-work confirmation as a safety gate.

Evidence & sources
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.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.

What is MegaFood Blood Builder Vegan Iron Supplement 60ct - New?
MegaFood Blood Builder Vegan Iron Supplement 60ct - New is a product from MegaFood, 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.
How does MegaFood Blood Builder Vegan Iron Supplement 60ct - New score on the Vyvata rubric?
76/100 overall — Verified tier (70–84 band). Per-dimension breakdown: Formulation 82, Evidence 78, Manufacturing 75, Safety 75, Transparency 72, Sustainability 62. Scored as of 2026-08-24.
Why did MegaFood Blood Builder Vegan Iron Supplement 60ct - New score in the Verified tier?
MegaFood Blood Builder — MegaFood is a legit clean-supplement brand (B-Corp, glyphosate-free certified). Blood Builder combines iron (whole-food-based ferrous bisglycinate ~ better GI tolerance) with vitamin C (aids absorption), B12, and folate (methylation cofactors for hematopoiesis) — evidence-based formulation choices. Published trial (Beals 2019 in Nutrients) showed MegaFood Blood Builder specifically raised ferritin in iron-deficient women. Held below Elite by (1) sold via 'This is Beauty US' reseller — MegaFood direct-purchase gives fuller brand documentation; (2) still requires prior blood-work confirmation for iron supplementation (safety); (3) sustainability certification is strong but not third-party-audited for every claim. Would move to Elite 85+ with direct-brand purchase + independently-audited sustainability + prominent 'confirm deficiency first' warning.
What are the strongest and weakest aspects of this product?
Strongest: Formulation at 82/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Evidence at 78/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Transparency at 72/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 62/100 (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.
Is MegaFood Blood Builder Vegan Iron Supplement 60ct - New third-party tested?
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.
What would move MegaFood Blood Builder Vegan Iron Supplement 60ct - New to a higher tier?
