Can NMN Reverse Ageing? What Science Really Says
Imagine if you could take a supplement that helps turn back the clock on ageing at the cellular level. Sounds like science fiction, right? Yet this is exactly what researchers at Harvard Medical School, led by renowned longevity expert Dr. David Sinclair, have been investigating with a molecule called NMN.
The question on everyone's mind is simple: Can NMN actually reverse ageing? Let's explore what the science says, how it works, and whether this could be the breakthrough we've been waiting for.
What Is NMN and Why Does It Matter?
NMN, or beta nicotinamide mononucleotide if you want to get technical, is a naturally occurring molecule in your body. It's found in small amounts in foods like broccoli, cabbage, cucumber, and avocado. But here's the thing: your body doesn't produce nearly enough of it as you age.
Think of NMN as the raw material your cells need to create NAD+, a coenzyme that's absolutely essential for life. Every single cell in your body relies on NAD+ to function properly. It powers your metabolism, repairs your DNA, and keeps your mitochondria (your cells' energy factories) running smoothly.
The problem? By middle age, your NAD+ levels have dropped to about half of what they were in your youth. This decline is one of the key drivers of ageing. Your cells simply can't maintain themselves as well without adequate NAD+.
