Many over-the-counter options exist, but it’s crucial to be cautious. Some men find success with supplements containing L-arginine or ginseng, as these can improve blood flow. However, results vary, and some products might not be safe or well-regulated. It’s always a good idea to consult a doctor before trying new supplements, as they can interact with other medications or conditions. Also, lifestyle changes like regular exercise and a healthy diet can significantly impact erectile dysfunction.
