Hi guys, new to this site. Having been involved in strength & fitness training for more than thirty years, my research and experience tells me there is no conclusive evidence that supplementation works. Most of the positive material comes from manufacturers and suppliers, not from independent science based sources. If you don't have the time to organize your whole food intake, make the time, it's that important. If you use supplements to "boost" your nutrition, the body will generally not recognize/accept it, and simply pass it out, in preference for the real stuff. Hence the yellow pee. Quite often the problem is the essential vitamins and minerals are unable to be absorbed and transported properly through the system due to a lack of correct hydration, as most people do not drink enough water. Even in some of those instances where you experience what is accepted as chronic pain, by increasing your hydration (and remember hydration=water) you can alleviate the symptoms. If your nutrition is sound, there is no need for supplementation. Because nutrition is such a vital topic, there are literally millions of readily available books, documents and articles on the subject. It is a multi-billion dollar industry, if you look closely enough, you will find each and every article has a contradictory argument somewhere. My philosophy is to keep it simple, focusing on fresh, whole, unprocessed and minimally packaged produce/products.
