It's a fair point and the powder is indeed a compromise, its reliable, stores well, I don't have to cook it and is fast. Raw egg would be great, except you would have to separate the egg whites as 2-4 yolks a smoothie every day could be problematic due to all things in the yolk.

I started with Soylent and that product really is a chemical mess. If I could just buy the brown rice/pea protein and flaxseed without all the vitamin additives it would be ideal and I do look for better powders every six months. To your point however, it can absolutely be improved and I am always looking for better ideas.
