Drug & Food Interaction of 21st Century L-Arginine 500mg Plus Capsule

Drug Interactions:

• Antihypertensive medications (e.g., amlodipine, enalapril) — L-Arginine may enhance blood pressure-lowering effects, increasing the risk of hypotension
• Nitrate medications (e.g., nitroglycerin, isosorbide) — combined use may cause an excessive drop in blood pressure
• Phosphodiesterase-5 (PDE5) inhibitors (e.g., sildenafil/Viagra) — potential additive effect on blood pressure reduction
• Blood thinners / anticoagulants (e.g., warfarin, aspirin) — may increase the risk of bleeding
• Diabetes medications (e.g., insulin, metformin) — L-Arginine may influence blood glucose levels; monitor closely
• Potassium-sparing diuretics — combined use may increase potassium levels in the blood

Food Interactions:

• High-lysine foods (e.g., dairy, eggs, legumes) — lysine and arginine compete for absorption; excessive lysine intake may reduce the effectiveness of L-Arginine supplementation
• Alcohol — may amplify the blood pressure-lowering effect and increase the risk of dizziness or flushing
• Grapefruit or grapefruit juice — may interfere with the metabolism of certain co-administered medications

💡 Always inform your doctor or pharmacist about all supplements, prescription medications, and over-the-counter products you are currently taking to avoid potential interactions.
