Antioxidants, like glutathione, are beneficial because they stop free radicals from cellular damage and death, preventing the chain reaction before the damage begins
While they can offer antioxidant support and brighten surface-level pigmentation, their effects are limited compared to oral or injectable forms, as glutathione molecules struggle to penetrate deeply into skin layers
The Injection (Subcutaneous) - Dosing: Once weekly - Bioavailability: ~100% (bypasses GI tract) - Weight loss in trials: Up to 22% at 36 weeks - Best for: Patients seeking maximum efficacy, comfortable with self-injection The Pill (Oral) - Dosing: Once daily (taken on an empty stomach, similar to Rybelsus) - Bioavailability: Lower than SC (relies on SNAC absorption technology) - Weight loss in trials: Up to 13.1% at 12 weeks (Phase 1 short duration) - Best for: Injection-averse patients, early treatment, maintenance, broader access The oral formulation will almost certainly deliver less weight loss than the subcutaneous version at equivalent treatment durations
If you are switching between weekly medications, you should not administer two medications in the same week
