Ask Dr. Block: Reishi, Spirulina & Chlorella

Can a patient take reishi together with spirulina and chlorella? Is there potentially harmful interaction between the three supplements?

No, there is no evidence of a harmful interaction. According to Natural Medicines Comprehensive Database, none of these supplements is likely to interact with other herbal medicines. However, it is important to note that each of these compounds have immune stimulating properties, relating to different aspects of immune defense. In theory, someone who has an autoimmune disease, or who is taking immunosuppressant drugs, using all three together could potentially upregulate immune activation and thus, might be problematic.
