Why this scored 55/100
Vitamin B2 (riboflavin) is an essential B vitamin with specific evidence for migraine prevention at 400mg/day (Boehnke 2004 Neurology RCT showing 59% reduction in migraine frequency; Schoenen 1998 established the dose). Dietary insufficiency of B2 is rare in Western diets. This SKU is 60 capsules of vitamin B2 with no per-capsule dose disclosed. For migraine prophylaxis the trial-evidenced dose is 400mg/day; RDA is 1.1-1.3mg/day — a 300x difference between deficiency-correction and migraine-therapy dose. Without per-capsule mg, buyers cannot dose intentionally for either use. Standard 55/100: legitimate isolated vitamin with real evidence for a specific therapeutic use, held down by no dose disclosure and no COA.

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.
