NAD+: Chronological Age Doesn’t Matter — What Truly Matters Is Your Biological Age
Age is typically defined as the length of time since birth. However, a person’s true physical condition and degree of aging are better reflected by their biological age rather than the number of years they have lived.
In recent years, with rapid advances in anti-aging research, concepts such as biological age, NAD⁺, and NMN have gradually entered public awareness. These developments have prompted deeper reflection on fundamental questions: How do we actually age? And is it possible to slow the aging process?
Part 1
Age: A New Metric for Measuring Aging
Chronological age can only tell us how many years someone has lived—it cannot reveal the true condition of their cells. In contrast, biological age is assessed based on physiological parameters such as cellular function, metabolic status, inflammation levels, and DNA methylation patterns.
For example, a 45-year-old individual may have the biological age of a 35-year-old, or conversely, may already exhibit functional decline typical of a 50-year-old. Behind these differences lies a series of complex yet measurable biological mechanisms.

NAD⁺: The “Energy Molecule” in the Aging Process
Among the many factors influencing aging, NAD⁺ (nicotinamide adenine dinucleotide) has attracted significant scientific attention. NAD⁺ is a coenzyme widely present in the human body and plays a central role in energy metabolism, DNA repair, and the regulation of oxidative stress.
As we age, NAD⁺ levels decline steadily . Research suggests that compared with younger individuals, NAD⁺ levels in older adults may decrease by as much as 50%. This decline is closely associated with reduced cellular repair capacity, insufficient energy supply, and increased inflammation—ultimately manifesting as various age-related degenerative changes.

NMN: A Key Precursor for Boosting NAD⁺ Levels
Because NAD⁺ molecules themselves have difficulty crossing cell membranes, scientific focus has shifted toward NAD⁺ precursors. Among them, NMN (nicotinamide mononucleotide) has become a major research hotspot.
NMN can be efficiently absorbed by cells and rapidly converted into NAD⁺, making it an effective way to replenish NAD⁺ levels in the body. Animal studies have shown that NMN can improve insulin sensitivity, enhance mitochondrial function, slow cognitive decline, and demonstrate anti-aging potential across multiple experimental models.
In recent years, several human clinical studies have also indicated that NMN exhibits good tolerability at appropriate dosages and may offer potential metabolic benefits.

Scientific Anti-Aging Requires Rational Expectations
Although NMN is approved for sale as a dietary supplement in several countries, it is not a miracle “longevity pill.” Its long-term safety, individual variability, and optimal usage strategies still require validation through larger-scale human clinical trials .
In addition, NMN production involves significant technical barriers. Raw materials from different sources vary considerably in purity, stability, and impurity control. Companies that possess core enzymatic synthesis technologies—such as BONTAC Bio—have notable advantages in raw material quality and supply stability, making them trusted partners for many global nutrition brands.
Overall, anti-aging is not about fighting time itself, but about maintaining optimal physiological function as we age. Scientifically assessing one’s biological age and supplementing cellular “fuel” through well-researched interventions like NMN represent important strategies for achieving healthy aging in the modern era.
