I have seen over the last seven years the benefits of men using L-arginine supplementation and boosting Nitric Oxide. Included in these benefits are prostate issues (See this article: http://www.mb.com.ph/articles/361886/prostatic-enlargement). The slow urine flow and frequent “wake-up-in-the-midlle-of-the-night” trips to the john greatly improved. If you are dealing with these issues it could very well be another case of low Nitric Oxide (NO). Give a good L-arginine supplement like Cardio 5000 a try. You may be very pleasantly surprised at good results!
