Your current supplement contains amino acids and vitamins, which may not be strong enough to treat erectile dysfunction on its own. Since it has not been effective, you should consult your doctor about clinically proven medical alternatives. The most common first-line treatments are PDE5 inhibitors, such as sildenafil, tadalafil, or vardenafil. These prescription medications improve blood flow and are highly effective. Your doctor will evaluate your health to recommend the safest option and correct dosage. Please be reassured that erectile dysfunction is very common and highly treatable; finding the right solution simply requires a professional medical consultation.
