According to the article, there’s no better “boner builder” than meds such as Viagra or Cialis. But what if your erections are hard and you just want them to be harder? Korean Red Ginseng is the natural supplement that will work according to Dr. Lipschultz. Most men respond to it well with few side effects. In one Brazilian study, two-thirds of men who popped 1,000 milligrams of Korean red ginseng three times a day for 12 weeks reported harder, longer-lasting erections than before the study. The downside: You’ll have to take the stuff every day. The supplement they recommend is Vitamin World Korean Ginseng.
