Beta Blockers

High-protein meals increase the bioavailability of certain beta-blockers by 53%. Beta blockers work by inhibiting beta-adrenergic receptors that respond to adrenaline. Beta blockers reduce heart rate and blood pressure by dampening the sympathetic nervous system's stress response. The 53% bioavailability increase from high-protein meals means the body absorbs roughly twice the intended dose, causing excessive heart rate reduction and blood pressure drops. Pharmaceutical beta blockers carry side effects that make natural alternatives worth considering for non-severe conditions. Beta blockers are prescribed for anxiety, particularly performance anxiety. Beta blockers are prescribed for arrhythmias, hypertension, angina, essential tremors, POTS, and secondary heart attack prevention.
