Quality Nutritional Powders produced in such a way as to preserve the maximum amount of nutrients possible. They are even harvested at night because that’s when the plants are the most nutritionally rich.
For Example AIM BarleyLife remains the most nutritious green juice on the planet. Only young, nutritionally dense plants are harvested. Enzymes are protected through a proprietary process, and rather then selling a leaf powder, BarleyLife is a juice powder concentrate. This means BarleyLife packs more nutrition per ounce while retaining more enzymes and simultaneously protecting against oxidation.
It is hard to find high quality nutritional products these days. This is why I use and promote AIM nutritional products. They go that extra step to be the best.
