I love all the products Secrets of the Tribe produces, and I take quite a few of them. I recommend them all!
I loved tincture version of spirulina since it was easier to take than in powder form. No scent. I used it during the cold and it helped to relieve some discomforts associated with that.
I actually have used the powder before to cook eggs and other dishes with spirulina in them. I use this liquid version for my veggie shakes in the morning and it works just as well.
