What is Biological Age (Can NMN Reverse Aging?)

Do you ever wonder why some people age more gracefully than others? Or why certain health conditions are more prevalent as we grow older? 

The answer may lie in our biological age. While chronological age simply measures the number of years we've been alive, biological age refers to how old our bodies truly are at a cellular level

Continue reading as I will discuss biological aging, its difference from chronological aging, and the potential of NMN in reversing age in this comprehensive guide. 

What is Biological Age, and How is it Measured?

The biological age of an individual refers to how well their cells are functioning and how much they've aged compared to the rest of their body.

A variety of factors, including genetics, lifestyle choices, and environmental factors, determine our biological age. While chronological age is an unchanging number, biological age can vary widely depending on these factors.

Several methods are available for measuring biological age, such as DNA methylation testing and measuring telomere length.

DNA methylation occurs when chemical groups (methyl) are added or removed from DNA molecules. As we age, our DNA methylation patterns change.

Telomeres are the protective caps on the ends of our chromosomes, and their length shortens as we age. 

Scientists can estimate a person's biological age by measuring telomere lengths or DNA methylation patterns.

How is Biological Age Different from Chronological Age?

In simple words, chronological age is your actual age— measured from the date of your birth. A person's biological age, on the other hand, reflects the changes that have occurred in their cells and tissues with age

This means that two people of the same chronological age may have vastly different biological ages depending on their lifestyle choices and genetics.

The biological age of a 60-year-old who exercises regularly, eats a healthy diet, and avoids smoking may be closer to that of a 50-year-old, while the biological age of a 60-year-old who is sedentary, eats a poor diet, and smokes may be closer to that of a 70-year-old.

By understanding our biological age, we can take steps to slow down the aging process and improve our overall health.

What is NMN, and How Does it Affect Aging?

NMN (nicotinamide mononucleotide) is a naturally occurring compound found in our bodies that plays a crucial role in energy metabolism. It is a precursor to NAD+, a coenzyme that is essential for many cellular processes, including DNA repair and gene expression. As we age, our bodies produce less NAD+, which can lead to cellular damage and contribute to the aging process.

Supplementing with NMN can increase NAD+ levels in the body, slowing down the aging process and reducing the risk of age-related diseases. In animal studies, NMN supplementation has been shown to improve insulin sensitivity, increase muscle strength and endurance, and improve overall healthspan.

Can NMN Really Reverse Aging?

Can NMN Reverse Aging

NMN has been shown to slow down the aging process and improve overall health, although more research is needed to determine its full effects on aging. According to a recent study, NMN reversed some aspects of aging, including improving mitochondrial function and increasing insulin sensitivity in mice. 

There have been few human trials conducted on this supplement. One such study recently published in Nature Communication concluded that NMN supplementation improved several age-related biomarkers in healthy middle-aged adults.
