Blue-Green Algae


  • Klamath Lake blue-​green algae is a form of microalgae phytoplankton that differs from spirulina in that it prefers fresh water as opposed to salty water.
  • Aphanizomenon flos-​aquae (AFA) blue-​green algae is a particular type of wild blue-​green algae that populates its natural habitat—a giant shallow body of water known as Klamath Lake in Oregon. At 125 square miles, Klamath Lake is the largest lake in Oregon. It is also at a relatively high altitude, 4,139 feet above sea level.
  • AFA has been harvested, filtered, cleaned, and dried from Klamath Lake for worldwide consumption since the 1970s.
  • AFA is a wild food harvested from a wild environment. Spirulina is a wild species usually grown in a controlled environment.


  • AFA contains an extraordinarily high concentration of the blue-​pigment phycocyanin (15 percent).


  • Phycocyanin helps fortify the immune system by stimulating the production of more stem cells from the bone marrow. Stem cells are the basic form of all cells and can be transformed into any cell (including red and white blood cells, T-​cells, NK cells, macrophages, and other immune system cell artillery).
  • Phycocyanin is an antioxidant that provides the intense blue color in blue-​green algae. Phycocyanin can constitute up to 15 percent of the dry weight of a blue-​green algae harvest; this is approximately twice the concentration of the phycocyanin found in spirulina.
  • The rare, blue-​colored phycocyanin helps inhibit the growth of certain cancer colonies, fights chronic inflammation, supports the liver, protects against free-​radical damage, improves the production of neurotransmitters, and aids production of rejuvenating stem cells.
  • Also found within AFA algae is a concentrated level of phenylethylamine (PEA), an adrenal and brain chemical naturally synthesized in our bodies from two amino acids: phenylalanine and tyrosine. PEA increases in parts of the brain that control our ability to pay attention and stay alert. Elevated PEA levels occur when we are captivated by a good book, movie, or project; this happens specifically during those moments when we are so focused that we lose all track of time, food, and the outside world.
  • PEA has also been dubbed the “love chemical.” It plays a role in creating feelings of attraction, excitement, and euphoria. When we fall in love, or in a new relationship, our PEA levels increase; we become peppy and full of optimism. The brain releases PEA when we are sexually aroused. PEA levels can peak during orgasm.
  • When the brain is flooded with PEA, the neurotransmitter dopamine is then blocked from being deactivated and dopamine levels rise. Elevated dopamine levels are associated with increasing mental concentration and a positive attitude.
  • PEA also increases the effectiveness of another neurotransmitter, nor-​epinephrine, which increases feelings of joy. In one experiment, investigators found that aerobic exercise can elevate the body’s levels of (PEA). PEA is part of the endorphin-​induced “runner’s high” that enhances energy, mood, and attention. When researchers had twenty healthy young men run on a treadmill for 30 minutes, they found that the average concentration of PEA in the participants’ urine increased by 77 percent. In addition, the research indicated that patients suffering from depression and bipolar disorder had lower-​than-​normal levels of PEA in their urine.               PEA is found naturally in great natural abundance in two foods that we know: cacao and blue-​green algae (especially in blue phycocyanin). These two foods can significantly elevate the presence of PEA in our brain.  AFA and cacao keep our PEA levels high, no matter what is happening in our life.
  • Drapeau references a study in his book Primordial Food that indicates oral doses of PEA at the rate of 10 mg per day decreased symptoms of depression in 60 percent of the patients tested. In addition, PEA did not cause the patients to gain weight, as most people do with antidepressants; instead, they actually lost weight. AFA contains approximately 2 mg per gram of PEA. AFA concentrates are now available that contain 10 mg of PEA per gram.
  • PEA appears to be the primary active ingredient that inhibits appetite and helps people to lose weight when they consume AFA blue-​green algae. In a double-​blind crossover study involving human patients, supplementing the diets of obese outpatients with 2.8 grams of blue-​green algae three times daily over a four-​week period resulted in a statistically significant reduction of body weight.
  • Blue-​green algae works synergistically with cacao in creating a strong ability to focus and pay attention even if we suffer from Attention Deficit Disorder (ADD). One study looking at blue-​green algae as a brain food followed 109 students who were fed blue-​green algae. The study concluded that the children had a significant improvement in the ability to focus, follow directions, and concentrate. In addition the children experienced a reduction in argumentative, demanding, and combative behavior, fewer symptoms of anxiety and depression, an improvement in social skills, and fewer signs of emotional and behavioral withdrawal. Isn’t it amazing how by adding just one food to someone’s diet, they would become less likely to act foolishly, and become happier, more social and more normal?
  • In his book, Primordial Food, Drapeau cites research performed by a team of scientists affiliated with the University of Illinois. More than two hundred cases were reviewed in this study. The study concluded that AFA appears to be effective in treating various viral conditions, chronic fatigue, Attention Deficit Disorder (ADD), depression, inflammatory diseases, and fibromyalgia.
  • Studies done on AFA have demonstrated that it stimulates the migration of stem cells from the bone marrow into the blood and brain (mostly due to the actions of the blue pigment phycocyanin), and stimulates white blood cells, preventing inflammation and improving nervous-​system health, as well as one’s overall mood.
