Blue-green algae encompasses several cyanobacteria, including Spirulina and Aphanizomenon flos-aquae, harvested for their dense nutrients. They supply protein, chlorophyll, B vitamins, iron, and antioxidants. People use them as a whole-food supplement for daily wellness.
Many take blue-green algae for energy, immune function, and a nutrient boost, especially vegetarians and vegans. Traditional use includes sharpening mental focus and enhancing vitality.
Capsules, tablets, and powders are common forms. Take them with meals to help absorption and avoid stomach discomfort. Start with a small dose and increase slowly to check tolerance.
Algae from unclean water may carry microcystin toxins. Pick a brand that tests for purity. Avoid blue-green algae if you have an autoimmune condition or phenylketonuria (PKU). It may interact with blood-thinning medications.
