How NMN Can Improve Lung Health: Benefits and Mechanisms

Lungs are essential respiratory organs in the human body, and healthy lungs are closely related to our quality of life. However, due to factors such as environmental pollution and life stress, the incidence of lung disease has been increasing year by year.

NMN is a vital substance widely present in organisms, closely related to NAD+ metabolism. NMN has a wide range of physiological functions, including anti-oxidation, anti-inflammatory, anti-aging, and other effects, which are crucial for maintaining lung health. This article will review the potential benefits of NMN on lung health and its mechanisms of action.


Anti-inflammatory effect of NMN Inflammation is one of the main factors leading to lung diseases. Long-term inflammatory reactions may cause airway remodeling and fibrosis, ultimately leading to a decline in lung function. NMN can alleviate inflammatory damage by inhibiting the inflammatory response. Studies have shown that NMN can inhibit the NF-κB signaling pathway, thereby reducing the generation of inflammatory factors.

At the same time, NMN can also increase the activity of the SIRT1 protein, further inhibiting the inflammatory response. In addition, NMN can lower the concentration of inflammatory cytokines such as IL-6 and TNF-α, thereby reducing the degree of inflammation.


Anti-oxidative effect of NMN Oxidative stress is one of the important factors leading to lung diseases. Excessive oxidative stress can cause damage to cell structures, leading to inflammatory reactions and a decline in lung function. NMN has significant anti-oxidative effects and can effectively remove excess free radicals. Studies have shown that NMN can enhance the activity of antioxidant enzymes such as SOD, CAT, and GPx by activating the SIRT1 pathway, thereby enhancing the cell's antioxidant capacity.

In addition, NMN can activate the Nrf2 pathway, further inducing cells to produce antioxidant factors. These antioxidant mechanisms make NMN a potential drug that may be used to treat lung diseases related to oxidative stress.


Anti-fibrotic effect of NMN Lung fibrosis is a common lung disease, characterized by excessive fibrous deposition in lung tissue, ultimately leading to a decline in lung function. NMN has good therapeutic potential in anti-fibrosis. Studies have found that NMN can inhibit the activation and proliferation of lung fibroblasts by suppressing the TGF-β1/Smad pathway, thereby inhibiting fibrosis occurrence.

Moreover, NMN can alleviate oxidative stress and inflammatory reactions, further reducing the risk of fibrosis. These research results indicate that NMN may become a potential drug for treating lung fibrosis.


Immune regulatory effect of NMN The immune system is essential for maintaining lung health. NMN, as a substance that can regulate immune responses, can affect the function of immune cells. Studies have shown that NMN can increase the phagocytic ability of macrophages, enabling them to more effectively clear infections and inflammatory factors.

At the same time, NMN can regulate the function of T cells, balance the ratio of Th1/Th2 cells, and reduce lung inflammation. These immune regulatory mechanisms make NMN a potential drug for the prevention and treatment of lung diseases.
