Take each at their normal times. CoQ10 and fish oil both support cardiovascular health and are commonly taken alongside beta-blockers. Melatonin — beta-blockers suppress melatonin production, so supplementing in the evening may help if sleep is disrupted. Space supplements 1-2 hours from Metoprolol.
Higher risk for: those with asthma or COPD, bradycardia, diabetes (may mask hypoglycemia symptoms), elderly, concurrent calcium channel blocker use, or peripheral vascular disease.
Monitor blood pressure and heart rate when combining Metoprolol with PQQ. Watch for: dizziness, lightheadedness (especially when standing up), fatigue, cold extremities, slow heartbeat, or swelling in ankles/feet. Check your blood pressure at home if possible.

No urgent discussion needed, but keep your provider informed. Say: "I take Metoprolol alongside PQQ — anything I should know?"
Safe combination at standard doses. Continue your medication as prescribed. Inform your doctor or pharmacist that you are using both, so they can monitor for any changes over time.
