First, it is important to recognize that PQQ is not a vitamin in the conventional sense; however, research suggests it may possess vitamin-like properties. It is primarily known for its ability to promote mitochondrial biogenesis, the process by which new mitochondria are formed within cells. This function is crucial because mitochondria are the powerhouses of cells, generating adenosine triphosphate (ATP), the energy currency that fuels a myriad of cellular activities. Enhanced mitochondrial function is associated with improved energy levels, better physical performance, and increased cognitive capabilities.
1. Gastrointestinal Distress Some users have reported experiencing upset stomach, nausea, or diarrhea after taking PQQ. This is quite common with many dietary supplements, especially if taken on an empty stomach or in high doses.
