Spirulina, a micro-algae, is the world’s best-known source of vegetable protein.
Spirulina is high in protein (60-70% of its dry weight). It also contains carbohydrates, essential fatty acids, vitamins, and minerals such as iron (50 times more than in spinach), zinc, magnesium, selenium, calcium, potassium, and phosphorus.
Take ¼ teaspoon (3 g) two times a day. Add it to juice, water, or smoothies. It also mixes very well in sauces, dressings, pesto, or dips.
