Unpacking NAD: What You Need to Know

Nicotinamide Adenine Dinucleotide (NAD) is a coenzyme found in all living cells. It is involved in numerous metabolic processes, making it an essential player in your body’s intricate biochemical symphony. One of the primary roles of NAD is to facilitate energy production within the cells. Through a series of enzymatic reactions, NAD helps convert food into ATP, providing the energy needed for all cellular activities. Without NAD, your cells would struggle to carry out their functions, leading to a cascade of health issues.

In addition to its energy-producing role, NAD is also involved in DNA repair. DNA is constantly bombarded by external and internal factors that can cause damage. NAD acts as a guardian, activating enzymes that repair DNA strands and maintain the stability of our genetic material. This crucial function ensures that your cells can continue to divide and function properly.

Unfortunately, with age, NAD levels naturally decline. This decline can have significant implications for your health and well-being. Reduced NAD levels can lead to decreased energy production, impaired DNA repair, and altered gene expression. These changes can contribute to the aging process and increase the risk of age-related diseases.

That’s where NAD+ precursor comes into play. As a precursor to NAD, it can be converted into NAD within the cells, helping to replenish NAD levels and maintain optimal cellular function. By supplementing with NAD+ precursors, you may be able to support your body’s natural processes and promote healthy aging.
