Ageing is viewed as a fixed, one-directional process, but emerging science is challenging this belief, offering a far more hopeful and empowering perspective.

Researchers are now increasingly focused not on how old we are in years, but on how old we are at a biological level. This concept, known as biological age, has opened the door to a new understanding of health, vitality and longevity. Interest has also grown in nutrients that support cellular energy and repair - in particular NAD (nicotinamide adenine dinucleotide).

So what role might an NAD supplement play in supporting healthy ageing?

For years, we’ve been told that ageing is inevitable—that our genetics determine how we grow older and what diseases we’ll face. But exciting new research is proving otherwise. Scientists now understand that our biological age (bio age)—how old our body actually functions at a cellular level—doesn’t have to match our chronological age. In fact, your bio age can move in reverse with the right lifestyle interventions.

This shift in understanding comes down to epigenetics—the study of how our environment and behaviors influence gene expression. While we inherit a set of genes from our parents, it’s our daily choices that determine how those genes are turned on or off. Through epigenetic processes like DNA methylation, we have the power to influence how our bodies age and whether we remain vibrant and disease-free as we grow older.
