Why this scored 60/100
Vitamin C (ascorbic acid) is a well-characterized water-soluble antioxidant and essential cofactor for collagen hydroxylation, carnitine biosynthesis, catecholamine synthesis, and iron absorption. RDA sits at 75-90mg/day for adults; supplement doses of 250-1000mg are common, absorption saturates around 200mg per single dose, and the tolerable upper intake is 2000mg/day (higher doses cause osmotic diarrhea). MRI Performance Vitamin C is a straightforward single-ingredient capsule at 180 count from an established sports-nutrition brand. The product does not disclose the per-capsule dose in the title (likely 500mg or 1000mg) or specify whether it is plain ascorbic acid, buffered (calcium/sodium/magnesium ascorbate), or contains bioflavonoids. Plain high-dose ascorbic acid can cause GI upset in sensitive users — a buffered version (like Ortho Molecular's Buffered C, also in this batch) mitigates that but costs more. Standard tier: a real single-nutrient vitamin C from a real brand at a reasonable count, unremarkable on transparency but not problematic on safety.

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.
