I've used it at times, I like it and would use it all the time but it gets expensive. I tried straight spirulina but that is a tough one for me to get down and I've chugged a lot of funky looking green smoothies. Mixing greens with that organic apple juice (unprocessed, cloudy) that comes in big glass jugs at the health food store works well but then I end up guzzling all the juice which is just too much sugar and also $$.
