NAD+ vs SS-31

Which should you choose? Here's what you need to know.

The short answer

NAD+ and SS-31 are both metabolic / longevity peptides, but they work differently. Nicotinamide Adenine Dinucleotide, a coenzyme essential for cellular energy production and DNA repair. Levels decline with age, driving longevity research interest. A mitochondria-targeted peptide (also known as Elamipretide) that stabilizes cardiolipin in the inner mitochondrial membrane. Studied for mitochondrial dysfunction. Compare vendor pricing and availability below.
