NMN Supplementation As A Strategy To Improve Oocyte Quality: A Systematic Review And Transcriptomic Analysis
As we age or experience metabolic stress, the quality of our egg cells, also known as oocytes, can decline. This decline is largely linked to problems with the cell’s energy factories, called mitochondria, and a decrease in a vital molecule known as NAD+. Think of NAD+ as a crucial fuel for many cellular processes, including energy production and repair.
Recent research has explored the potential of nicotinamide mononucleotide (NMN), a compound that the body can convert into NAD+. Essentially, NMN acts as a building block to help restore NAD+ levels within cells.
Preclinical studies, primarily conducted in animal models, have demonstrated exciting results. Supplementing with NMN has been shown to improve how mitochondria function, reduce harmful oxidative stress (an imbalance that can damage cells), and even help regulate processes related to inflammation and cell survival. These positive effects were observed in situations involving metabolic, environmental, and age-related stress.
Further analysis of human egg cells has revealed that genes critical for mitochondrial function and managing oxidative stress undergo significant changes as the egg cell matures. These findings align with the known ways NMN works, suggesting that boosting NAD+ levels could indeed be a key strategy to support healthier egg development.
Overall, these discoveries suggest that approaches targeting NAD+ metabolism, particularly through NMN supplementation, hold promise for improving egg quality. This could offer new avenues for addressing fertility challenges, especially those related to age. However, it’s important to note that while the findings are encouraging, more standardized protocols and clinical trials are needed to fully understand NMN’s potential and translate these benefits to human reproductive health.
