This decline, known as immunosenescence, is a major factor in why older adults are more vulnerable to diseases like influenza, pneumonia, and even certain cancers. In recent years, researchers have been exploring ways to support immune health during aging, and one compound that has drawn attention is NMN, or nicotinamide mononucleotide. NMN is a precursor to NAD+, a vital molecule involved in energy production and cellular repair. While NAD+ levels naturally drop as we get older, supplementing with NMN has been shown in studies to help restore these levels, which may have a positive ripple effect on the immune system.<br/></p><br/><p>One of the primary mechanisms by which NMN supports immunity is by enhancing the activity of immune cells such as T cells and natural killer cells. These cells are responsible for identifying and destroying infected or abnormal cells. In aging individuals, their performance often declines, but animal studies suggest that NMN can help rejuvenate them by improving mitochondrial function and reducing cellular stress. Well-functioning mitochondria empower these defenders to move, respond, and attack threats effectively.<br/></p><br/><p>NMN also appears to help regulate inflammation. Chronic low-level inflammation, often called inflammaging, is common in older adults and can damage tissues while suppressing immune responses. By boosting NAD+, NMN activates sirtuins, a group of proteins that help control inflammation and maintain cellular balance. This mechanism may not only enhance immune cell responsiveness—calming down the harmful overactivity that can weaken the system over time.<br/></p><br/><p>Another important benefit is NMN’s role in supporting the thymus gland, which produces T cells. The thymus shrinks with age, leading to fewer new immune cells being generated. Animal research indicates that NMN can help slow this decline and even promote partial regeneration of the thymus, potentially increasing the output of fresh, functional T cells.<br/></p><br/><p>While human studies are still in early stages, the existing evidence points to NMN as a promising tool for maintaining immune resilience in aging populations. It is not a cure, but rather a supportive nutrient that works at the cellular level to improve the body’s natural defenses. For older adults looking to stay healthier longer, NMN may offer a science-backed way to complement other healthy habits like good nutrition, regular exercise, and quality sleep.<br/></p><br/><p>It is important to note that NMN supplements should be used with care and ideally under the guidance of a healthcare provider. <a href="https://ajuda.cyber8.com.br/index.php/Evaluating_The_Chronic_Risks_Of_High-Dose_NMN_Supplementation">read more</a> research is needed to determine optimal doses and long-term effects in humans. Still, the growing body of evidence suggests that supporting NAD+ levels through NMN could be an important step toward preserving immune function as we age. Future clinical protocols may integrate NMN as a foundational intervention<br/></p> > > 웹 에디터 끝
