The agave is natural but does cause a BG increase of course. It does appear slower though. Have you tried Sucranat? It's in the organic section of your grocery store, near the organic honey usually. It too is real sugar, but minimally processed, so no rapid spike. They take sugar cane, squeeze out the liquid, then dry it into the sucranat crystals. It's used in alot of 'Clean Eating' Recipes. Tastes odd by itself, but great in teas, smoothies and baking
