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. Our Aloe Vera also contains over 200 other naturally occurring nutrients such as enzymes, amino acids, sterols and more.
