What makes Klamath blue-green algae a superfood?

Wild blue-green algae from Klamath Lake, Oregon is different and distinct from most algaes. It is a wild, uncultivated plant food. It is one of the few species of algae which grows wild in its own natural habitat, one of the world’s most rich “nutrient traps.” Klamath blue-green algae is the most nutrient dense food on the planet, containing glyco-proteins, vitamins, minerals, simple carbohydrates, lipids and biologically active enzymes. Due to algae’s nutritious soft cell wall, these nutrients are readily available to the body. As the body uses only a small amount of energy to convert this superfood into fuel, consuming Klamath blue-green algae is a fast, efficient, and energizing way to improve any diet. The extraordinary and natural environment in which wild blue-green algae is grown is impossible to duplicate on algae farms. Wild blue-green algae are completely free of artificial, synthetic influences. Because AFA is so purely and naturally grown in its own wild habitat, it has the most beneficial impact upon the human body.
