It's amazing to me that I can't find any major dangers in regards to the consumption of Aphanizomenon flos-aquae (AFA).
What I do know is keep your E3 Live frozen at all times and only defrost the AFA that you'll consume. This will help insure the benefits of the algae and keep it fresh and alive.
Here's one danger I found:
There are serious concerns about the safety of eating AFA, because it can sometimes contain potent nerve toxins. While the scientific literature is full of information concerning the toxicity of AFA and its dangers to humans and animals, there are few, if any, peer reviewed scholarly scientific papers regarding therapeutic benefit. In contrast, the scientific literature is full of information concerning the benefits and safety of humans and animals eating Chlorella.1
It could be possible there hasn't been enough test done to determine any dangers in the product, But for now this is all I can find.
If you have any medical conditions or are pregnant, please consult your medical physician before consuming this product. There is not any major warnings, but it's better to be safe than sorry.
Ill keep a look out for any other information I can find on this product.
Tomorrow is AFA weekly round up and of course a personal tip of the day about choosing your words wisely, since they might be creating something you don't want.
