Chlorella powder is 65% assimilable protein. Rich in chlorophyll, beta carotene, vitamins, minerals, amino acids, DNA, RNA and enzymes. It is also an excellent source of dietary fiber. Chlorella is rich in a nutrient factor isolated in the 1950s and not available in other green foods called 'Chlorella Growth Factor' (CGF). This CGF makes chlorella most useful for improving growth patterns in children, maintaining health in old age, healing injuries and initiating growth where it has been stunted from disease or degeneration.
