- Standard Capsule (Reduced GSH)
- 500mg
- <10%
- Once daily
- $15–30
- Low clinical efficacy. Most degraded before absorption
- Liposomal Encapsulation
- 500mg (split 250mg × 2)
- 30–40%
- Twice daily
- $40–70
- Gold standard for oral delivery. Best evidence base
- Sublingual Tablet
- 250mg
- 25–35%
- $35–60
- Comparable to liposomal but fewer published trials
- S-Acetyl-Glutathione (SAG)
- 15–25%
- $25–45
- Better than capsule, not as reliable as liposomal
- Topical Cream (5–10% GSH)
- Applied nightly
- Minimal systemic
- $30–50
- Limited to localised brightening. Inconsistent penetration
- Liposomal formulation at 250mg twice daily delivers the highest plasma GSH elevation relative to cost and adverse event profile. Standard capsules fail the bioavailability threshold required for melanocyte saturation. Topical formulations serve as adjuncts, not primary interventions.
