It's an extremely nutritious food, very high in antioxidants and chlorophyll. You might want to Google it and see just how many nutrients are in it, which is why it's called a "superfood."
thnak you...but I now see it's a supplement of two algas at $97 a go?? Have I misread it?
Spirulina is a blue-green fresh water algae -- only one algae. You can buy it a lot cheaper than that, so I think you've stumbled onto a multi-level direct marketing venture. If you want to try it, powder works best but tastes pretty bad. I take the pills every day -- you have to take several because it's food. You can find it at any good health food store. The two best brands readily available are Earthrise and Nutrex Pacifica.
