Prokaryotes, organisms without a nuclear membrane (e.g., blue-green algae), display a more diverse array of antioxidant pigments and a broader selection of carotenoids than terrestrial plants and most green algae.
Scientists at the University of Wisconsin, Department of Food Microbiology, report that because of the remarkable health benefits of algal and microbial carotenes, there will likely be a substantial increase in the world-wide demand for a full range of these important antioxidants. 252
Boost the human body’s defenses
Carotenoids represent one of the most widely distributed and structurally diverse classes of natural pigments, with important functions in photosynthesis, nutrition, and protection against photo-oxidative damage.
Pigments, phytochemicals, vitamins, and trace elements from algae and higher plants can help boost the human body’s antioxidant defenses. 256, 257
Aph. flos-aquae has an unusually wide variety of antioxidants, such as tocopherols, beta-carotene, flavonoids, superoxide dismutase, glutathione, taurine, tryptophan, phenolic acid, and vitamins C, E, B5, and B2. Antioxidants are biomolecules that protect organisms from the damaging effects of reactive oxygen species (free radicals) that are constantly formed in biological systems.
