Spirulina inhibits allergic reactions
Inhibitory effect of mast cell-mediated immediate-type allergic reactions in rats by spirulina.
High relevance for allergy treatment
We explored how spirulina impacts mast cell-mediated allergic reactions. In our investigation, we found that spirulina significantly inhibited both systemic and local allergic responses in rats, completely blocking reactions induced by compound 48/80 when given in certain doses.

Additionally, we saw that spirulina reduced histamine levels and inhibited mast cell functions, which typically promote allergic reactions. These findings suggest that spirulina has a promising role in mitigating immediate-type allergies, both in laboratory settings and potentially for future practical applications.

Spirulina peptides may reduce allergies
The role of peptides derived from Spirulina maxima in downregulation of FcεRI-mediated allergic responses.
High relevance to allergy treatment.
We investigated how peptides from Spirulina maxima might help manage allergic reactions. By testing two specific peptides, P1 and P2, on mast cells—key players in allergies—we found they significantly reduced symptoms like histamine release.

P1 worked by blocking calcium signaling, while P2 suppressed processes that typically lead to allergic responses. Overall, our findings suggest that these peptides could be effective options for developing new treatments and dietary ingredients aimed at alleviating allergies.

Spirulina shows mild allergy relief
Therapeutic efficacy of spirulina against ovalbumin and cigarette smoke-induced asthma-specific stress biomarkers in Sprague-Dawley rats.
Moderate relevance for practical use
We explored how spirulina might help with allergic asthma by conducting a study on rats. The rats were divided into four groups, with one group receiving spirulina, while others received a standard treatment for comparison. After inducing asthma through injections, we observed that spirulina reduced certain stress biomarkers related to asthma.

Notably, spirulina lowered total cells and specific inflammatory markers in the lungs, but salbutamol—a common asthma medication—was more effective overall. While spirulina showed promise in easing mild to moderate symptoms, more research is essential for human applications.

Natural antihistamine
Works wonders for my seasonal allergies. I used to rely on Zyrtec and nasal sprays, but now I just take Spirulina and a probiotic. While I tried reducing my Spirulina intake, I noticed a return of symptoms, but resuming my normal dosage quickly improved my condition. This stuff works for allergies!

Less aggravation
My allergies are no longer a major problem since I started using this product. I take three daily, which is half the recommended dosage. I hardly reach for anti-histamines anymore, and it has improved my energy levels too.

Reduced symptoms
I absolutely love this product. After stopping other vitamins to evaluate its effects, I've felt better than I have in ages. Normally, cottonwood heightens my allergies, but now I only have a few sneezes, feeling excellent overall.

Spirulina supports immune function
Effects on Spirulina Supplementation on Immune Cells' Parameters of Elite College Athletes.
Moderate relevance to allergies
We explored how spirulina supplementation affects immune cells in young soccer players during their training for a tournament. In a study of 39 athletes, those who took spirulina showed a notable change in immune cell ratios compared to those who received a placebo.

While spirulina appeared to help maintain stable immune function, the placebo group experienced significant differences in their immune cells over time. These findings suggest that spirulina may enhance immunity and possibly alleviate rapid-onset allergies, although more research is needed to confirm these effects.

Spirulina enhances IgA antibody levels
Class specific influence of dietary Spirulina platensis on antibody production in mice.
Moderate relevance to allergy management
We investigated how Spirulina affects antibody production related to allergies in mice. Our study revealed that while Spirulina did not increase IgE levels—associated with allergic reactions—it did enhance IgG1 and notably boosted IgA levels when given alongside an allergen. This suggests that spirulina may not worsen allergies but can help build up IgA, offering some protective benefits against allergic reactions. Overall, it seems that Spirulina extract might be a supportive option in managing food allergies without triggering further reactions.

Controls Rhinitis
This is one of the best supplements I've ever tried. I struggled with Rhinitis and allergies constantly until I discovered Spirulina. It not only enhances overall health and aids in controlling blood glucose, but also helps lower cholesterol. I highly recommend it; the quality is outstanding.

Seasonal relief
A good veggie substitute for seasonal allergies. My vegetable intake is quite low, so I use these Spirulina pills to supplement. They've been effective, as my allergies during pollen season are significantly diminished. Living in a high pollen area, Spirulina has made this time much more bearable for me and others I know.
