Pyrroloquinoline quinone is a small, redox-active molecule that plays a crucial role in cellular energy metabolism and the protection of cells from oxidative damage. Research has shown that pQQ can catalyze the activity of enzymes, promote the growth of new mitochondria (the powerhouse of cells), and enhance cognitive function. This makes it an appealing supplement for those interested in maintaining energy levels and supporting brain health.
PQQ is naturally found in foods such as kiwifruit, green tea, and fermented soybeans. The average dietary intake is relatively low, leading to interest in supplemental forms of PQQ. Studies have suggested that supplementing with PQQ may enhance cognitive function, improve sleep quality, and promote heart health. Furthermore, it has demonstrated potential in neuroprotection, suggesting it may help guard against neurodegenerative diseases.
Theophylline's influence extends to the central nervous system, where it can stimulate the respiratory centers in the brain. This stimulation enhances the drive to breathe, contributing to the medication’s effectiveness in addressing respiratory issues.
