The longevity market is full of supplements and drugs: NAD+ boosters, senolytics, rapamycin, metformin, resveratrol, spermidine, and many others. Some of these areas are scientifically interesting, but that does not mean each product has been proven to extend human life.
Why There Is So Much Hype
Lab research, animal data, and early clinical observations are often turned into marketing claims. The problem is that a mechanism is not the same as proven benefit, and improving one marker does not always mean fewer diseases or more healthy years.
Senolytics and Rapamycin
Senolytics target senescent cells, while rapamycin is linked to growth pathways such as mTOR. These topics are actively studied, but self-prescribing drugs for longevity can be risky. Medications have side effects, contraindications, and interactions.
A drug being scientifically interesting does not make it a safe biohack for everyone.
NAD+ and Popular Supplements
NAD+ is involved in cellular metabolism, which explains the interest in its precursors. But consumers should separate biochemistry from clinical outcomes. The question is not only whether a supplement changes a marker, but whether it improves health, function, and long-term risk.
A Reasonable Approach
First cover the basics: sleep, movement, nutrition, blood pressure, lipids, glucose, not smoking, and alcohol moderation. Then discuss supplements with a clinician, especially if you have medical conditions or take medication.
A supplement should not replace treatment, screening, or stronger evidence-based habits.
Bottom Line
Longevity supplements and drugs are interesting but risky territory. It is useful to follow the science, but early research should not become self-treatment. The best filter is simple: is there proven human benefit, a clear safety profile, and a reason this applies to you?
