One way to help beef up you and your child’s immune system against the annual winter onslaught of flu viruses and other infections is to take a natural immunostimulant. Chlorella is one of the finest natural immune stimulants and has been shown to help prevent and treat colds.  The normal preventive dose for an adult is 5 tablets three times a day. Dr. Steenblock wrote a book on Chlorella titled “Chlorella, Natural Medicinal Algae” which can be purchased on-line from Amazon.com. Chlorella can be ordered by calling 1-800-300-1063.
