Route & Efficacy Honesty
High
Honesty about glutathione’s bioavailability by route and about its off-label use — especially framing around skin-whitening claims.
Why it matters
Glutathione is marketed for skin-whitening on thin evidence, and oral bioavailability is poor. Honest framing on both fronts is what separates a responsible provider from a claims-driven one.
How we assess it
We read the route-and-claims honesty.
- Bioavailability honesty across routes
- Honest, non-overstated framing of off-label skin-whitening use
Source types: The provider’s efficacy and route claims.
How we score it
Candid framing of route limits and off-label use scores high. Overstated skin-whitening claims are the red flag and pull the subscore down.

- High
High — a heavily weighted tier within glutathione.

What this tier is worth
Tiers carry fixed weights: Critical 5, High 3, Medium 2, Supporting 1. A score is the weighted mean of the factors we could establish, so you can recompute any of ours by hand — the methodology page works one through end to end.
Not medical advice
This factor rates how openly a provider discloses its process — not whether a treatment is right for you. That decision belongs with a licensed clinician who knows your history. Nothing here is medical advice.
