Where does the algae come from?

If it comes from mercury- or other toxin-laden areas, the omega-3 may cross the blood-brain barrier and deposit whatever it's laden with in the brain.

People are farming algae in isolated environments to eventually make diesel. Seems more direct, higher-margin (lower volume, admittedly) and more ethical to squeeze healthy edible oil out of the algae instead.
