I have been using Lightforce greens for a month now and I thought I would post a thread. The stuff is great...I wouldn't say that it gives you a huge amount of extra energy like some of the athletes that endorse the product say it does, but it does make you feel healthier and more balanced for sure. What really made me try Lightforce Greens was that it has alkaloids in it which raise your body pH. There is a whole school of thought that preaches raising one's body pH is the key to a healthier lifestyle. Many of the things that people in this country consume including coffee, preservatives, fast food, and processed foods lower the bodies pH creating your body chemistry very acidic. If a plant's pH or the soil that the plant is in has a low/high pH the plant will block out certain nutrients and make the plant deficient of those nutrients. This makes me believe that if a humans body pH is off, the human body will, on some level, block out certain nutrients and not perform at peak levels. If anyone is looking for a green supplement I would go for the Lightforce Greens. I have tired the GNC greens formula and also the Trader Joes Greens formula. This one blows them away because of the alkaloids. It is also a great value! I actually paid for overnight shipping when I ordered mine and I got a email back saying that they were back ordered. They said they would send me a extra tub of it for the inconvenience and followed through. Now I have one at my office and one at home. Bottom line...try this product! Hit me up if you have any questions about it.
