Agave Nectar Low Glycemic Sweetener. Known in Mexico as aguamiel, or “honey water”, Agave Nectar was considered a gift from the gods by the ancient Aztecs, and today is considered nature’s perfect sweetener by many. Agave Nectar (also called Agave Syrup) is minimally processed using low temperatures and has a low glycemic index. NOW Real Food Organic Amber Agave Nectar is a medium-intensity liquid sweetener with a taste closer to maple syrup. Its stronger flavor makes it ideal for use in more hearty culinary applications, and it’s an excellent substitute for maple syrup. It dissolves quickly and easily in both hot and cold beverages, so use it right out of the bottle for a healthy splash of natural sweetness!
