NAD+ for burnout and depression: what the science says

What did @cococolaah actually say?

At week three of NAD+ injections, she called it her "second favorite peptide" and said she "feels it not just on the day of injecting it." She's dosing three times a week and connecting the benefits to her baseline burnout, describing herself as someone dealing with "depression and grief and ADHD" who suspects her NAD levels are naturally depleted. The core claim is simple: sustained energy and mood improvement from a course of NAD+ injections.

She's not claiming a cure. She's not prescribing a dose. She's reporting a personal experience against a specific backdrop of stress, grief, and neurodivergence. That context actually matters when evaluating whether her experience is plausible, and to her credit, she provided it unprompted.

Does the science back this up?

Partially, and the partial part is more interesting than a flat yes or no. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme involved in cellular energy metabolism, DNA repair, and mitochondrial function. The idea that supplementing it improves energy and mood isn't wild, but the human evidence for injected NAD+ specifically is thin.

Most of the credible work focuses on NAD+ precursors, particularly NMN and NR, taken orally. Yoshino et al. (2021, Science) showed NMN supplementation improved muscle insulin sensitivity in postmenopausal women, suggesting NAD+ precursors can raise tissue NAD+ levels. A study by Conze et al. (2019, Scientific Reports) confirmed NR raises blood NAD+ in healthy adults. What it doesn't show is that raising NAD+ reliably translates to subjective energy or mood gains in people who aren't metabolically impaired.

For IV or injected NAD+, the published clinical literature is sparse. Most citations you'll find reference addiction and withdrawal settings, not general wellness or mood optimization. The gap between "NAD+ is important to cells" and "injecting NAD+ will make you feel better" is real, and it's wider than most TikTok content acknowledges.

What did they get wrong (or right)?

She got the self-awareness right. Framing her response as potentially amplified because "naturally my NAD levels are low" is actually a reasonable hypothesis. Chronic stress, sleep disruption, alcohol, and depression have all been associated with lower NAD+ availability. If she's genuinely depleted, she has more room to feel an effect than a healthy 25-year-old would.

What she got wrong, or at least glossed over, is calling NAD+ a peptide. It isn't. NAD+ is a coenzyme, not a peptide. Peptides are short chains of amino acids. Lumping NAD+ into peptide content is a common categorization error on wellness platforms and it muddies how people research and evaluate these compounds.

She also attributes the mood lift partly to NAD+ without accounting for placebo, behavioral change, or the natural regression that comes after bottoming out emotionally. Three weeks is not enough time to separate those signals. That doesn't mean her experience isn't real to her. It means she can't yet know why it's happening.

What should you actually know?

NAD+ injection protocols are not FDA-approved for depression, ADHD, grief, or energy optimization. They're used off-label, typically through telehealth providers, and the side effect profile for injected NAD+ includes flushing, nausea, and chest tightness, particularly with faster administration. These aren't rare, and they're worth knowing before you start.

The "course" framing she uses is appropriate. NAD+ is not meant to be a permanent daily supplement in injectable form, and reputable providers structure it as a defined protocol, not an indefinite regimen. Anyone considering this should be evaluated by a licensed clinician who can assess baseline metabolic and mental health status before prescribing.

The honest answer is that for people who are genuinely depleted from chronic stress, burnout, or certain health conditions, there is a plausible biological mechanism for why NAD+ support could help. But "plausible mechanism" and "proven treatment" are not the same thing. If you're struggling with depression, NAD+ is not a substitute for evidence-based mental health care.

Bottom line

Her experience sounds real, and her reasoning is more grounded than most NAD+ content on TikTok. But three weeks of subjective improvement is not proof, NAD+ is not a peptide, and the clinical evidence for injected NAD+ in mood or energy disorders is genuinely limited. The enthusiasm is understandable. The extrapolation needs to stop there.
