What makes Klamath Blue-Green Algae so interesting?
Klamath Blue-Green Algae (AFA) is a naturally nutrient-rich freshwater algae traditionally harvested from Upper Klamath Lake in Oregon.
Its complex nutritional profile includes chlorophyll, carotenoids, amino acids and naturally occurring pigments and phytonutrients.
One particularly interesting component is PEA (phenylethylamine), a naturally occurring trace amine also produced by the human body. PEA is involved in signalling within the nervous system and has attracted scientific interest in areas including mood, attention and neurological function.
Klamath algae is also valued for its naturally occurring pigments, including phycocyanins, which continue to be studied for their antioxidant and other biological properties.
Rather than providing one isolated nutrient, Klamath Blue-Green Algae offers a naturally complex whole-food nutritional profile.

PEA refers to phenylethylamine, not palmitoylethanolamide.
