One of the most important Chlorella benefits is balancing the bowel. As we grow older, many of us battle chronic constipation. Although it might seem like a minor annoyance, constipation is actually a serious threat to your health. Toxins linger in the bowel far too long, breeding disease in that area, and seeping poisons into the bloodstream. Every organ in the body can be dragged down by the bowel. Fatigue, headaches, bad breath, and cancer of the colon and breast are all associated with constipation. Chlorella provides significant relief to constipation sufferers. Japanese researchers have determined that Chlorella increases peristalsis, the rhythmic contractions which force waste products onward. Other studies show that Chlorella encourages the growth of friendly bacteria in the digestive system and discourages the growth of harmful ones.
