You may not have realized it, but if you have ever eaten Spirulina, you were eating algae. Yes, that stuff that people with chlorinated swimming pools dread. Or that on occasion causes massive ocean hypoxic (dead) zones also known as red tide.

Spirulina is a particular type of cyanobacteria (blue-green) algae. In reality, the color is closer to green-black than blue-green. In fact, the powder is so dark that it appears almost as black as that food poisoning remedy known as Activated Charcoal. You can see this characteristic from the picture above. Spirulina is incredibly fine like activated charcoal too. As a result, you can make a huge mess if you spill it, which is probably why spirulina tablets have become so popular as an alternative to the powder.

So what makes this particular superfood so special? Why has it been embraced so strongly in the healthfood community as a popular supplement? Is taking spirulina a serious or spurious proposition?
