As we age, memory decline and slower reaction speed are common troubles for many people. Behind brain aging, there may be a set of “energy switches” — the redox ratios of NADH/NAD+ and NADPH/NADP+. A landmark 2026 study in Frontiers in Aging Neuroscience uncovers the mysterious link between these ratios, brain aging, and dietary anti-aging, and we’ll […]

1. Anti-Aging Becomes a New Trend in Nutritional SupplementationIn the past, people’s choices for nutritional supplements were often limited to vitamins, minerals, proteins, and other categories, generally believing that these nutrients are closely related to maintaining the balance of human functions and strengthening the body. Today, the significance of dietary supplements is no longer limited

A new study published in Nature Communications by the team of Sarah Dimeloe at the University of Birmingham (UK) has uncovered a groundbreaking role for NAD in immune regulation. Through systematic in vitro and in vivo experiments, the research reveals for the first time how NRK1 controls CD4+ T-cell immunity, clarifying the core mechanism by which cytoplasmic

When it comes to NADH, many people first think of its anti-aging benefits. As a core member of the NAD+ family, its roles in energy metabolism, antioxidant defense, and neuroprotection are well recognized, making it a popular ingredient for relieving chronic fatigue and supporting neurological health. But in the eyes of scientists, NADH has a

Do you often feel low on energy, short of breath after climbing just a few flights of stairs, or completely exhausted the day after long work hours? Don’t simply blame it on “poor physical condition.” A randomized, placebo-controlled trial published in August 2025 in the European Journal of Medical and Health Sciences (Vol 7 | Issue 4)

What goes on deep within the brain? This age-old question has long eluded clear answers—yet NADH is unexpectedly revealing some of its profound secrets.As a pioneer in cellular energy enhancement and antioxidant processes, NADH is not only a critical player in maintaining health but also a key tool in scientific research. Its concentration changes are

NAD+ (nicotinamide adenine dinucleotide), a core coenzyme in cellular metabolism, is involved in multiple physiological processes including redox reactions, energy metabolism and signal transduction. Dysregulation of its metabolism is closely associated with the development and progression of various diseases. In recent years, the therapeutic potential of NAD+ precursor supplements in disease models has been widely

Is There a Preference in NAD+’s “Energy Supply”?NAD+ is a core coenzyme for cellular energy metabolism, participating in critical physiological processes including mitochondrial ATP production, DNA repair and immune regulation. Its role, however, is analogous to a “power system” — just like glucose and daily dietary intake, NAD+ provides basic energy for all cells, rather
