So, I have been enjoying the benefits of AFA from Klamath Lake daily since 1996. I've been to the lake, and having a degree in geography, have studied as to how this wonderful resource of super food came into being. Although there are other sources of notable "green food", ie. chlorella and spirulina, I absolutely prefer the AFA from Klamath Lake! People ask, "what will it do for me?". I tell them, "whatever your body needs done first". Then your body will redirect the power of the algae to the next task. Most people lack the discipline to "eat" their algae consistently till they can evaluate it's affect. Most times the body uses it first to "grab a broom" and clean, before it starts to build. This can take 30 to 60 to 90 days. If I can have only one supplement to my diet, it would be AFA. As an "Ironman" triathlete, and an ultra runner and now as a cancer survivor I have had countless opportunities to put it to the test. The E3 AFA is fresh, potent and priced right. Drink plenty of good quality water along with each serving.
