Collection: Algae, seaweed

The best-known algae and seaweed are spirulina, chlorella, and sea kelp.
Spirulina and chlorella algae are similar in terms of nutrients; both contain Vitamin B1 (thiamine), Vitamin B2 (riboflavin), folate (Vitamin B9), and magnesium. The difference is that spirulina also contains copper, while chlorella is richer in iron and also contains zinc and vitamin A (retinol).
