What are the effects of spirulina

Spirulina, a type of blue-green algae, has garnered attention for its potential health benefits, particularly regarding respiratory health. Here are some key effects of spirulina based on discussions from Andrew Huberman on the Huberman Lab:

1. Reduction of Rhinitis Symptoms: Spirulina has been shown to significantly reduce symptoms associated with allergic rhinitis, including nasal obstruction and inflammation. In studies involving over 100 subjects, spirulina led to improvements in nasal airflow and the ability to smell, alongside reduced nasal itching (1).

2. Improved Sleep Quality: Participants taking spirulina reported better sleep. Improved respiratory function and reduced nasal congestion can contribute to more restful sleep during infections or allergic reactions (1).

3. Immunological Effects: Spirulina is noted for its ability to inhibit the activity of histaminergic mast cells. These cells are involved in allergic reactions and inflammation, meaning spirulina may help modulate the body's immune response to allergens (1).

4. Natural Alternative to Medications: Compared to conventional over-the-counter medications (like cetirizine), spirulina presents a natural alternative that can have fewer side effects, such as dehydration or drowsiness, which are sometimes associated with typical allergy medications (1).

Overall, spirulina is emerging as a promising natural supplement for managing symptoms of respiratory allergies and improving overall health. If you're considering taking spirulina or any new supplement, consulting with a healthcare professional is advised.
