Spirulina
Sources:
Spirulina, a form of algae, has been highlighted by as a potent alternative to conventional over-the-counter medications for reducing symptoms of congestion and inflammation, particularly related to allergies. He discusses this in the context of addressing cold symptoms like a runny or stuffed-up nose, which are commonly treated with medications that can lead to dehydration and sleep disruption. Spirulina, however, offers a natural way to alleviate these symptoms without these side effects.
Dr. Huberman references studies that show significant benefits of spirulina in treating allergic rhinitis (nasal inflammation). These include reductions in nasal obstruction and itching, improved ability to smell and sleep, and decreased inflammatory cytokines. The studies he refers to are human studies which highlight the efficacy of taking 2 grams of spirulina. This treatment can sometimes take a while before the effects are evident, but the results include improved nasal functionality and overall comfort.
Additionally, spirulina's effectiveness in addressing allergy symptoms is explained by its ability to inhibit the activity of histaminergic mast cells. These cells are involved in the body's allergic responses, leading to symptoms like swelling and inflammation. also provides a cautionary note for individuals with phenylketonuria (PKU), a genetic condition, as they might experience negative side effects from spirulina.
Despite its somewhat new-age reputation, spirulina is supported by solid research illustrating its capability to moderate immune responses, particularly in the context of allergies. 1 2
