Scientific studies show polysaccharides to be responsible for many of aloe's health benefits. Nature's Way Aloe Vera is enhanced with Aloe PolyMax (a proprietary aloe polysaccharide extract), making it the most potent and effective source of natural aloe polysaccharides. Nature's Way Aloe Vera also contains over 200 other naturally occurring nutrients such as enzymes, amino acids, sterols and more. This product contains organically grown Aloe Vera that is harvested at the peak of nutrient potency and freshly cold-processed to yield 65% pure Aloe. No aloin, bitter constituents or additional water are present. Nature's Way Aloe Vera is guaranteed fresh. We use a unique nitrogen process which eliminates oxidation and preserves our potency. Our Aloe Vera is independently certified by both the International Aloe Science Council (verification of aloe content and purity) and the International Aloe Certification Laboratories (verification of polysaccharide content).
