NAD+ and anti-aging supplements: cutting-edge science or expensive promise?

What science really shows

Here honesty is needed: much of the impressive results come from studies in animals and cells. Supplements like NMN and NR can indeed raise NAD+ levels in humans — that's reasonably demonstrated. What is NOT yet proven is that this rise translates into living longer, aging slower or preventing disease in people. The large long-term trials are missing.

The case of resveratrol and company

Resveratrol (from red wine) was once a star and then disappointed in human studies. It's a good reminder: lab enthusiasm is no guarantee of real benefit in your life.

The Lair's sensible stance

• Treat these supplements as experimental, not a proven solution.
• Be suspicious of any marketing that promises to reverse aging — science isn't there.
• The strongest-evidenced 'anti-aging' isn't in a vial: it's strength training, aerobic capacity, sleep, real food and bonds.
• If you want to try something trendy, do it with spare money and low expectations — and talk to a doctor.

Real youth is defended with habits, not hype.

A word from the Lair: this content is informational and does not replace medical care. Don't start supplements with anti-aging claims without professional guidance, especially if you take medication.
