Are there side effects to blue green algae supplements?

Krista, I've been adding Klamath Blue green algae to my boost. I've been using it on and off for about 3 weeks now. No more than a tsp of it. I recently came across this Wiki entry about possible side effects that has me more than a bit concerned. ALS? For real?

Some cyanobacteria produce toxins, called cyanotoxins. These include anatoxin-a, anatoxin-as, aplysiatoxin, cylindrospermopsin, domoic acid, microcystin LR, nodularin R (from Nodularia), neosaxitoxin and saxitoxin. Cyanobacteria reproduce explosively under certain conditions. This results in algal blooms, which can become harmful to other species if the cyanobacteria involved produce toxins.

These toxins can be neurotoxins, hepatotoxins, cytotoxins, and endotoxins, and can be toxic and dangerous to humans as well as other animals and marine life in general. Several cases of human poisoning have been documented but a lack of knowledge prevents an accurate assessment of the risks.[34][35][36] Recent studies suggest that significant exposure to high levels of some species of cyanobacteria producing toxins such as BMAA can cause amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's Disease). The Lake Mascoma ALS cluster [37] and Gulf War veteran's cluster are two notable examples.[35][36][38]

To my knowledge I have not heard of any type of outbreak or concern from food-grade blue-green algae supplements. I know that our SuperGreens formula goes through rigorous bacterial testing and processes to ensure safe-food standards. While I cannot speak to another manufacturer, most who sell quality products test them before selling to consumers.
