Is chlorella safe?

If the label is true: Chlorella is a common green pond scum, with some nutritional value. Some folks have packaged it as a nutritional supplement and will sell it to you. The "superfood", anti-cancer, immune-enhancing and similar claims are all made up (breaks no law, strangely.) if the bottle contains what it says it does (and in this shadow world it often doesn't), you're safe. It's your money.

Chlorella: Chlorella is possibly safe when used short-term (up to 2 months). The most common side effects include diarrhea, nausea, gas (flatulence), green discoloration of the stools, and stomach cramping, especially in the first week of use. Chlorella has caused serious allergic reactions, including asthma and other dangerous breathing problems. Chlorella can cause skin to become extra sun sensitive.
