Spirulina is a blue-green algae loaded with protein, vitamins, and antioxidants. Organic spirulina often comes from tightly controlled growing conditions, so the risk of contamination is lower than with some other algae like chlorella. Its cell wall is soft, which makes it easy to digest.
People commonly take spirulina to bolster daily energy and support immune health. It also supplies general antioxidant activity and can help maintain healthy blood fat profiles already in the normal range. Most mix the powder into smoothies, juice, or water, or swallow tablets with a meal to get the best absorption and avoid stomach upset.
Quality matters a lot with this supplement. Stick to reputable organic sources to steer clear of toxins. Because spirulina contains vitamin K, it can interfere with blood clotting, so anyone on anticoagulants should check with their doctor first. The algae can also rev up the immune system, which means people with autoimmune conditions should be careful.
