Chlorella works a little like a probiotic.  It supports the growth of natural bacteria in the large intestines.  Also, chlorella contains an ingredient called chlorellin that acts as a natural antibiotic.

As you are probably aware, chemical antibiotics often have undesirable side effects.  They not only attack the harmful bacteria, they also kill the useful and necessary bacteria.

The great thing about a natural antibiotic like chlorellin is that it kills the harmful bacteria while leaving the friendly bacteria alone. Chlorella is quite efficient in handling bacterial infections. It's like the perfect antibiotic similar I guess to garlic.

These days with all the flu and viruses floating around it would be a good idea to add chlorella to your natural defense regimen.
