Why this scored 52/100

Oral reduced (L-) glutathione has poor systemic bioavailability due to GI proteolysis — Richie 2015 did show intracellular GSH increase at 250-1000 mg/day, but liposomal or S-acetyl forms deliver measurably better plasma results. A 500 mg standard oral cap sits in a legitimate but ineffective-for-many format. Not autofailed since a small population may still benefit, but form choice holds it below Standard. Would move to Standard 62+ with liposomal or acetylated delivery.

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.
