Chlorella is a single-celled micro-algae and is green due to its high chlorophyll content. Chlorella has been around for two-billion-years on this planet and has survived because its strong outer shell protected its genetic integrity. Broken cell-wall chlorella is nearly twice as digestible as other chlorella. It has a complete vegetarian protein that is 58% highly-digestible. It contains many minerals, vitamins, and phytonutrients. This chlorella comes in a glass jar.
