I've for a while now used Boku Super Protein brand powder supplement. It's completely plant-derived and very diverse, unlike most other plant-based proteins, which only source from soy.
Call me a luddite, but the idea of "supplements" in general is wacky to me (unless you have a health disorder). If I want protein I get it from food. If I want vitamins I get it from food (or other crazy things like sunlight). These things exist in nature for a reason; science didn't create the notion of a healthy body.
In fact, i'd propose that some people think about their health a little too much (myself included). Do something outside and don't eat a lot of crap. K.I.S.S.
Sure, there's nothing wrong with that approach. But, for the same reason that you might put shoes on your feet when you go do something outside, you might find employing certain other technological advances useful in achieving your goals. We don't, after all, burn wood in our cars, we use gasoline -- even though the fundamental principle underlying both is the release of energy stored in hydrocarbon-based fuel. The difference is a step-function in refinement.
It depends on how goal-directed you are in this domain. Others may have higher, more specific, or more urgent health/fitness goals.
