I don't like spirulina powder. I buy the tablets and take those, because the powder doesn't taste good (to me). The only way I've found I like, strangely enough, is to put it in homemade salad dressings. For some reason it's a hit :)

I've also used it in powder form during a juice fast because if you're really feeling like you need to eat, but don't want to break your fast, spirulina can save the day. I've literally gotten a natural high from it.
