Spirulina inhibits allergic reactions
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
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
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.

Fast allergy relief

This is the purest spirulina I have purchased! I initially tried a cheaper brand but soon returned to this one due to its superior quality. It has an excellent algae smell and no chemical aftertaste. The results are evident much faster than others—my allergy symptoms vanished. I only buy this brand now and encourage others to do the same for the best results!

Kids' allergies reduced
4 people found this helpful
I've been using this product for over a year for my children, and the results have been remarkable. My eldest son’s allergies diminished to the point where his paediatrician inquired about my methods. They rarely get sick, and when they do, it lasts a shorter duration. One bottle lasts about six months, and I will definitely keep using this product.

My allergies have significantly improved—a completely unexpected side effect. I started taking this for the iron, but noticed I needed allergy medication less often. After researching, I found that spirulina has beneficial effects on allergies. Now I only take 2-4 pills a week if I anticipate an attack, which is a massive improvement.

Spirulina supports immune function
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.

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.

Reduces allergy rhinitis
1 people found this helpful
Spirulina is packed with nutrients, containing much more iron than spinach and protein that the body absorbs more effectively. It boasts healthy fats that help the body adapt to environmental stresses and can decrease the risk of allergic and inflammatory reactions. Notably, it alleviates symptoms of allergic rhinitis from pollen, pet dander, and dust. Simply taking 2 grams daily can relieve rhinitis, and adding lemon juice can enhance taste and vitamin absorption. This may control cravings and support weight management, although taking it with food could reverse its benefits.

Reduces allergy mood

I love spirulina for its beneficial properties. For years, I’ve relied on it as my primary vitamin source due to allergies to synthetic vitamins. I’ve found that spirulina aids in lowering my body’s allergic reactions. I always opt for high-quality spirulina, avoiding Chinese products. While I was fond of local options, I now consistently order Hawaiian spirulina. Recently, I watched a film highlighting the chemical testing in Hawaii, raising concerns about buying spirulina from there.
