Chlorella boosts immune defenses

Lengthy, strenuous exercise increases chances for upper respiratory infections (URI) in athletes, as the immune salivary system secretes fewer protective antibodies.

In this study, 34 healthy, physically active men and women took a placebo or 6 grams of chlorella per day, beginning four weeks before and continuing two weeks after two days of intense exercise training.

By week four, protective immune antibodies in mucous secretions were increasing for the chlorella group, but not for placebo, and continued to increase during training and afterwards at rest. Both groups reported a similar number of URIs, but doctors believe chlorella would provide effective protection from respiratory infection by taking the supplement longer.
