Aloe Vera is traditionally found in warm, arid locations, like the Caribbean and Northern Africa and has been used for thousands of years. Nature's Way Aloe Vera is enhanced with Aloe PolyMax+ (a proprietary aloe polysaccharide). Guaranteed fresh. Because aloe nutrients deteriorate when exposed to oxygen, Nature's Way Aloe Vera is bottled using a unique nitrogen process to eliminate oxidation and preserve potency. Independently certified for quality, Nature's Way Aloe Vera is certified by the International Aloe Science Council (verification of aloe content and purity).
