Both Spirulina and Chlorella are food therefore there is no need to consider them food substitutes. In fact, they are the two most powerful foods known. Nothing comes close. They are the only two foods you can live on exclusively and get all your essential nutrients. There are many foods that you can survive on, but none that will provide you with all the nutrients you need to live a healthy life.
Spirulina and Chlorella DO have a major side-effect: Great Health.
