NAD+ vs. Glutathione Injections: Which Anti-Aging Treatment May Be Right for You?
NAD+ and glutathione are two of the most popular injectable anti-aging treatments available through compounding pharmacies. While both target age-related decline, they work through fundamentally different mechanisms: NAD+ focuses on cellular energy production and DNA repair, while glutathione serves as the body's primary antioxidant defense system. Understanding these differences may help you and your provider determine which — or whether both — could be appropriate for your health goals. Both are compounded medications and are not FDA-approved.
| Feature | nad-plus-injections | glutathione-injections |
|---|---|---|
| Primary Function | Cellular energy production and DNA repair | Antioxidant defense and detoxification |
| Mechanism | Coenzyme supporting sirtuins, mitochondrial function, and metabolic reactions | Neutralizes free radicals, supports detoxification pathways, recycles other antioxidants |
| Common Goals | Energy, cognitive function, metabolism support | Detoxification, skin health, immune support |
| Administration | Subcutaneous injection or IV infusion | Subcutaneous injection, intramuscular injection, or IV infusion |
| Price Range | $105 - $350/month | $75 - $200/month |
| FDA Status | Compounded — not FDA-approved | Compounded — not FDA-approved |
| Evidence Base | Preclinical research is promising; large-scale human clinical trials are still limited | Well-studied antioxidant; injectable forms have less clinical trial data than oral forms |
| Oral Alternatives | NMN and NR supplements (NAD+ precursors) | Liposomal glutathione (may improve bioavailability vs. standard oral) |
Choose nad-plus-injections if...
NAD+ injections may be more appropriate for adults whose primary goals involve supporting cellular energy, cognitive function, or metabolic health. If you are interested in the intersection of NAD+ science and longevity — particularly the research around sirtuins and mitochondrial function — NAD+ injections may align with those interests. NAD+ is also commonly selected by those who have already tried oral NAD+ precursors and want to explore injectable delivery. Keep in mind that the evidence base for NAD+ injections in humans is still developing.
Choose glutathione-injections if...
Glutathione injections may be more appropriate for adults focused on antioxidant support, detoxification, and skin health. Glutathione is the body's most abundant endogenous antioxidant, and injectable forms aim to deliver it more effectively than standard oral supplements. If your primary concerns involve oxidative stress, environmental toxin exposure, or supporting immune function, glutathione may be the more targeted option. It also tends to be less expensive than NAD+ injections.
The Verdict
NAD+ and glutathione target different aspects of aging and cellular health, so the choice between them depends on your individual priorities. Many longevity protocols actually combine both — NAD+ for energy and cellular repair, glutathione for antioxidant defense and detoxification. Neither is a proven anti-aging solution, and both are compounded medications that are not FDA-approved. A qualified provider can help you evaluate which approach, or combination, may be most appropriate for your health profile and goals.
