The Common Anxiety of Modern People: Fatigue and Accelerated Aging

Do you often feel a lack of energy, reduced focus, and slower recovery?

• After 30: Working late leaves you groggy the next day, and recovery is nowhere near what it was in your student years.
• After 40: Concerns about memory decline, reduced physical strength, and even noticeable changes in skin and immunity begin to appear.
• After 50: Signs of aging become more obvious, and many start seeking “anti-aging” solutions.

In fact, these conditions are closely related to the decline of a key molecule in the body — NAD (Nicotinamide Adenine Dinucleotide).

Studies show that NAD levels gradually decrease after the age of 20, and by the age of 50, may drop to just half of youthful levels. This decline means insufficient cellular energy, weakened DNA repair, and reduced metabolic efficiency.
