The mechanism by which NMU induces mutations is primarily through its alkylating properties. Upon exposure, NMU can add alkyl groups to DNA bases, leading to mispairing during DNA replication. This results in transitions or transversions in the nucleotide sequence, which can ultimately lead to permanent mutations. If these mutations occur in critical genes responsible for regulating cell growth and division, such as proto-oncogenes and tumor suppressor genes, they may lead to uncontrolled cell proliferation and cancer.

It is important to note that while PQQ shows promise in these areas, research specifically connecting PQQ to COVID-19 outcomes is still in its infancy. Most of the current understanding stems from the broader contexts of immune function and chronic diseases rather than direct evidence in COVID-19 patients. As the scientific community continues to prioritize this area of research, clinical trials will be essential in establishing effective dosages and understanding the mechanisms through which PQQ may exert its benefits during viral infections.

CoQ10 is a naturally occurring antioxidant that is found in every cell of the body, particularly in the mitochondria, the powerhouse of the cell. It plays a crucial role in the production of adenosine triphosphate (ATP), the primary energy carrier in cells. As we age, our body's ability to produce CoQ10 diminishes, leading to reduced energy levels and increased oxidative stress. Consequently, supplementing with CoQ10 has been shown to improve energy levels, enhance exercise performance, and support heart health.
