We explored the potential of a Spirulina cold water extract to combat influenza, a virus that poses significant health risks. Through thorough testing in animal models, we observed that this extract is both well-tolerated and effective in inhibiting the replication of various influenza strains, even those resistant to common treatments. It works early in the infection process, reducing the virus's impact and improving survival rates in infected mice. While promising, further clinical trials are necessary to confirm its effectiveness in humans.

We explored the effectiveness of Immulina®, a supplement derived from Limnospira, in helping improve immunity against the flu in mice. Using two models, one where mice received the supplement before infection and another where it was given after symptoms began, we found that the preventive use of Immulina® showed promising results.
However, when administered after flu symptoms emerged, it didn't prove to be effective. These insights pave the way for better future research on flu treatments.

Eliminates flu signs

I take three of these every morning with breakfast and have done so for the past 2-3 years. Since starting, I haven’t caught a cold or the flu. This product is completely natural, and I’ve never experienced any side effects.

Immunity booster noted
Spirulina boosts white blood cell and antibody production, aiding in the fight against viruses like the flu and HIV. It also helps reduce cataract risk and supports gut health. Research indicates that this superfood is rich in beneficial vitamins and minerals.

Reduced flu episodes
Great product! It helped me get through last winter with fewer flu episodes. I also experienced improved concentration and energy levels. I wish the tablet was softer or smaller, but there's no aftertaste or breath odour.

Supports immunity well
My daughter takes three pills every morning on an empty stomach. Most of her classmates are infected with influenza A, but she remains in good condition. I believe these pills are beneficial for her immunity and digestive health.

Boosts immunity effectively
Spirulina is rich in vitamins such as E, C, and B6, and, when combined with other minerals, it supports our immune system. Research suggests that spirulina enhances the production of white blood cells and antibodies that combat viruses, including flu and HIV. It may also lower the risk of cataracts and age-related vision loss, along with benefits for gut health.
