5 Anti-Aging Supplements Worth Knowing About

These five supplements keep coming up in longevity research and clinical discussions. None are magic pills, but each has a reason people are paying attention.

NMN (Nicotinamide Mononucleotide)

NMN converts to NAD+ in your cells. NAD+ is needed for energy production in mitochondria, and levels drop as you age. The idea is simple: boost NMN, boost NAD+, support cellular energy.

What makes it interesting is that the NAD+ pathway exists in almost every living thing — from yeast to humans. That suggests it’s fundamental to aging, not a minor player.

Creatine

Most people think gym supplement. But creatine also supports brain energy. Your neurons need ATP just like your muscles do.

Some research has looked at high-dose creatine (around 20g/day) for cognitive support, though typical doses are 3–5g. It’s cheap, well-studied, and underrated outside fitness circles.

Nitric Oxide (from food)

Not a pill — you get this from beets, spinach, arugula. Nitric oxide relaxes blood vessels and improves circulation.

Production drops with age, which may partly explain why cardiovascular issues increase over time. The trick: you need to actually chew leafy greens. Bacteria in your mouth convert nitrates to nitric oxide. Mouthwash kills those bacteria.

Honokiol

Comes from magnolia bark. Used in Asian medicine for centuries, now studied for anti-inflammatory effects. It crosses the blood-brain barrier, which is rare and potentially useful for brain health.

Less mainstream than the others, but showing up more in longevity protocols.

Modified Citrus Pectin

A modified form of pectin that can be absorbed (regular pectin can’t). It binds to heavy metals and may help remove them from the body.

Also being studied for its effect on galectin-3, a protein linked to inflammation. Less data than NMN or creatine, but gaining interest.

The Bigger Picture

Supplements work best alongside the basics: sleep, movement, real food, stress management. No pill compensates for poor habits.

If you’re considering any of these, get bloodwork first. Know your baseline. Then you can actually measure if something helps.
