The active ingredient in erythromycin is erythromycin itself, which is derived from the bacterium Saccharopolyspora erythraea (formerly known as Streptomyces erythreus). The compound works by inhibiting bacterial protein synthesis, which ultimately leads to the cessation of bacterial growth and replication. Beyond the active ingredient, erythromycin formulations often include several excipients or inactive ingredients that aid in the medication's stability, absorption, and overall efficacy.

PQQ may also confer benefits for cardiovascular health by aiding in the reduction of inflammation and arterial stiffness, both of which are risk factors for heart disease. Mitochondrial dysfunction is often linked to cardiovascular issues, and by promoting healthy mitochondrial function, PQQ could play a preventive role in maintaining heart health.

  • The 35% refers to the ideal contact ratio between the oil seal lip and the rotating shaft. This percentage is crucial as it ensures a balance between sealing effectiveness and minimal friction. If the contact ratio is too high, excessive heat generation and wear can occur, potentially leading to seal failure. On the other hand, a low contact ratio may result in inadequate sealing, allowing oil to escape or debris to enter.
