Why are there 1 million types of protein powder??!!

I'm going to make this really easy on you and save you a ton of time in the grocery aisle. Garden of Life makes the best protein powder. Raw, vegan, blah blah but most important - it has the most amount of protein per calorie. I get the vanilla and put it in as much as I can. Smoothies, oatmeal, pudding, anything that can use a kick of protein! I just cut your grocery visit time by twenty minutes - you're welcome. http://www.gardenoflife.com/Products-for-Life/Foundational-Nutrition/RAW-Protein.aspx
