I don't think they actually are that similar. Ensure doesn't even get you close to the recommended amount of macronutrients, unless you're trying to lose weight. Ensure has 210-350 calories [0], yet high levels of micronutrients which means if you drink too many of them you risk taking in way too much of some vitamins and minerals. Soylent is meant for healthy people who want to consume a normal amount of macro and micro nutrients each day. [0] http://ensure.com/nutrition-faq http://ensure.com/nutrition-faq
