Even though many products claim to help with erections, it's important to talk to a doctor before trying any of them. An amino acid called L-arginine is often sold as a natural way to treat erectile dysfunction (ED) because it improves blood flow. Ginkgo biloba is another well-known vitamin that may help with ED. Some men think that plant products like maca root or horny goat weed can make them more sexually interested. But there isn't a lot of solid evidence to back the effectiveness of these vitamins, and different people react differently to them. ED can be treated with prescription drugs like sildenafil (Viagra) or tadalafil (Cialis), but you need a prescription from your doctor to get them. A healthy diet, exercise, and good stress control are all important for general health and have a big impact on sexual health. Before starting any pill plan for erection problems, you should always talk to a doctor first.
