The 7 billion-plus people on the planet are a pretty diverse bunch. But one thing, maybe the only thing, that unites us all is that none of us is getting any younger—and we’re all trying to fight that inevitability in one way or another. We hate getting older.
Hence the rapidly growing anti-ageing industry, valued at over US$200 billion today and expected to be double that by 2030. From anti-wrinkle cream to botox treatments, we’re spending more money than we have ever before to delay the ageing process.
But that’s to prevent the appearance of ageing. What if I told you there’s a medical treatment, evidence-based and peer-reviewed, that can actually slow down the body’s natural deterioration? Oh, and it can also give you more energy, a better memory and improved cognitive function, thank you very much. You’d likely, and quite rightly, be sceptical.
Well, we haven’t found an evidence-backed fountain of youth quite yet, but one scientist, Harvard professor of genetics David Sinclair, believes we’ve never been closer. Sinclair led a March 2017 study on a compound called nicotinamide adenine dinucleotide, or NAD.
NAD is found in all living cells. It’s critical for regulating cellular ageing and maintaining proper function of the whole body. Our NAD levels naturally decline over time—we’ve known this for a while. What Sinclair proved was that artificially raising levels of NAD in mice caused the ageing of tissue to reverse, leading the rodents to look and act younger, and live longer.
