NAD+ (Nicotinamide Adenine Dinucleotide) vs Glutathione
NAD+ (Nicotinamide Adenine Dinucleotide) and Glutathione are both longevity peptides, which is why they get recommended interchangeably — but they are different compounds with different origins. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
Both are classed as Longevity peptides, so they get compared constantly and are often researched for overlapping reasons.
Route of administration differs — NAD+ (Nicotinamide Adenine Dinucleotide) is typically subq (or slow im), Glutathione is typically im/subq. That alone changes how convenient each one is to keep up with.
Where they overlap: cellular energy, dna repair support.
Reported mainly for NAD+ (Nicotinamide Adenine Dinucleotide): mental clarity, anti-aging.
Reported mainly for Glutathione: antioxidant defense, skin brightening.
What NAD+ (Nicotinamide Adenine Dinucleotide) is
Nicotinamide Adenine Dinucleotide (NAD+) is not a receptor ligand in the traditional sense, but rather a crucial coenzyme involved in fundamental cellular biochemistry. It acts as a redox carrier, accepting and donating electrons in numerous metabolic pathways such as glycolysis and oxidative phosphorylation, thereby facilitating the production of cellular energy (ATP). Additionally, NAD+ serves as a vital substrate for enzymes like sirtuins (SIRTs), poly(ADP-ribose) polymerases (PARPs), and CD38, which are integra
What Glutathione is
Glutathione is a ubiquitous tripeptide, gamma-L-glutamyl-L-cysteinylglycine, found in nearly all mammalian cells, where it functions as a primary endogenous antioxidant. Rather than targeting specific receptors, it exerts its effects through direct chemical reactions and as a crucial cofactor for numerous enzymes, including glutathione S-transferases (GSTs) and glutathione peroxidases (GPx). The key to its biochemical activity lies in the thiol group of its cysteine residue, which allows it to participate in redox
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — NAD+ (Nicotinamide Adenine Dinucleotide) and Glutathione are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between NAD+ (Nicotinamide Adenine Dinucleotide) and Glutathione?
Both are classed as Longevity peptides, so they get compared constantly and are often researched for overlapping reasons.
Can you log NAD+ (Nicotinamide Adenine Dinucleotide) and Glutathione in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, NAD+ (Nicotinamide Adenine Dinucleotide) or Glutathione?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
