SS-31 vs Glutathione
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: Elamipretide, Bendavia
A mitochondria-targeted peptide that improves cellular energy production. FDA approved for Barth syndrome (September 2025) as FORZINITY, the first approved mitochondria-targeted therapeutic.
Also: L-Glutathione, GSH
The body's master antioxidant - a tripeptide composed of glutamate, cysteine, and glycine. Found in every cell at concentrations similar to glucose (5mM). Essential for detoxification, immune function, and cellular protection against oxidative stress.
Key Comparison Insights
- SS-31 is FDA approved, while Glutathione remains in research stages.
- Both peptides belong to the Anti-Aging category, suggesting similar primary applications.
- SS-31 has stronger research evidence (FDA Approved) compared to Glutathione (Human Trials).
Detailed Comparison
| Attribute | SS-31 | Glutathione |
|---|---|---|
| Category | Anti-Aging | Anti-Aging |
| FDA Status | FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | SS-31 concentrates 1000-fold in mitochondria, binding to cardiolipin on the inner membrane. It optimizes electron transport chain function, reduces reactive oxygen species, and prevents cardiolipin peroxidation during cellular stress. | Glutathione directly neutralizes free radicals including superoxide, hydroxyl radicals, and nitric oxide. It regenerates other antioxidants like vitamins C and E. Through glutathione peroxidase enzymes, it detoxifies peroxides and lipid peroxides. The GSH/GSSG ratio (typically >100:1 in healthy cells) determines cellular redox status. Also critical for Phase II liver detoxification, binding toxins for excretion. |
| Common Dosing | 40 mg subcutaneous daily Once daily | 500-1000 mg daily (oral or liposomal) 1-2x daily |
| Administration | Subcutaneous injection or IV infusion | Oral, liposomal, IV, or subcutaneous |
| Typical Duration | Variable by condition | Ongoing supplementation or 4-12 week courses |
| Best Time to Take | Morning | Morning on empty stomach, or evening |
Possible Side Effects May vary by individual |
|
|
| Research Summary | FDA approved for Barth syndrome in September 2025 under accelerated approval. Ongoing trials for dry age-related macular degeneration and primary mitochondrial myopathy. Studies show improved cardiac function, exercise capacity, and mitochondrial efficiency. | Extensive research across multiple therapeutic areas. Clinical trials show benefits for liver health, skin lightening (via melanin modulation), neurodegenerative conditions, and immune support. FDA grants GRAS status for food use. Studies on Parkinson's patients showed symptom improvement with IV administration. Liposomal forms show improved bioavailability in clinical studies. |
Frequently Asked Questions: SS-31 vs Glutathione
What is the difference between SS-31 and Glutathione?
SS-31 is a anti-aging peptide that a mitochondria-targeted peptide that improves cellular energy production. fda approved for barth syndrome (september 2025) as forzinity, the first approved mitochondria-targeted therapeutic. Glutathione is a anti-aging peptide that the body's master antioxidant - a tripeptide composed of glutamate, cysteine, and glycine. found in every cell at concentrations similar to glucose (5mm). essential for detoxification, immune function, and cellular protection against oxidative stress. The main differences lie in their mechanisms of action and clinical applications.
Which is better, SS-31 or Glutathione?
Neither is universally "better" - the choice depends on your specific goals. SS-31 is typically used for anti-aging purposes, while Glutathione is used for anti-aging. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can SS-31 and Glutathione be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using SS-31 and Glutathione together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
