In our study, we examined how epipharyngeal abrasive therapy (EAT), which includes the use of zinc chloride, affects the expression of a key molecule known as Cav1.2. This molecule is essential for the influenza virus to enter cells, making it a crucial target in flu prevention strategies.
We compared two groups of patients: those who received EAT and those who did not. Our findings revealed that the levels of Cav1.2 were significantly lower in the EAT group, at a striking 4.19 times less than in the non-treated group. This suggests that the squamous metaplasia induced by EAT—which is a process of changing the epithelium—could be a beneficial approach to limiting flu infections.
The results of the study highlight zinc's potential indirect role in flu prevention by remarking on its contribution to lowering the expression of a critical receptor for the virus. Although we didn't isolate the effects of zinc alone, the findings indicate that treatments involving zinc, like EAT, may offer a straightforward way to help limit the impact of influenza.

We set out to uncover how Euglena extract might help combat influenza, particularly focusing on its components like zinc. This microalga, known for its nutritional benefits, has shown promise in alleviating flu symptoms in mice. Our investigation revealed that Euglena extract significantly inhibited various strains of the influenza virus, including those that resist traditional antiviral medications like oseltamivir and amantadine.
Through our research involving Madin-Darby canine kidney (MDCK) cells, we discovered that the extract doesn't disrupt the virus's replication cycle directly. Instead, it appears to bolster the host's defenses, which means it enhances our body's natural ability to fight off the virus. One of the key contributors to this antiviral activity seems to be the minerals present in the extract, particularly zinc.
Overall, this study suggests that Euglena extract could be a promising tool for flu prevention and treatment. Its potential benefits highlight the need for new approaches in tackling influenza, especially with the rise of drug-resistant strains. Our findings advocate for further exploration into how zinc and other components in Euglena can enhance our defenses against influenza.

We explored the role of zinc in supporting our immune system, especially in the fight against influenza. The studies suggest that zinc might be beneficial in reducing the viral load during flu infections.
Evidence shows that zinc can decrease the severity of symptoms associated with viral pneumonia, which is often a complication of influenza. Additionally, it appears to have a positive impact on the overall recovery process, potentially shortening the duration of illness.
We also noted that zinc may enhance the effectiveness of certain COVID-19 treatments, which gives further credence to its immune-boosting properties. However, the precise relationship between zinc levels and vaccine effectiveness, particularly for flu vaccines, remains complex and requires more investigation.
Ultimately, our understanding indicates that incorporating zinc into our regimen could provide an additional layer of defense against the flu virus while supporting our immune health.

This zinc supplement is exceptionally beneficial during the cold and flu season, particularly with the ongoing pandemic. Zinc picolinate has better bioavailability, which I believe reduces illness frequency. I use it daily with vitamin D3, ensuring that I manage the dosage correctly, making it an essential part of my health regimen.

We investigated the potential of zinc in combination with herbal polyphenols and copper to reduce the infectivity of respiratory RNA viruses, including the flu. This study is particularly timely due to the ongoing challenges posed by viruses like SARS-CoV-2, highlighting the need for effective therapeutic solutions.
Zinc ions are known to play a role in modulating viral RNA replication, which makes them an appealing option for decreasing viral loads and infectivity. However, a significant challenge is that the natural concentration of zinc in our cells is often too low for effective results. To tackle this, we combined zinc picolinate, a form of zinc that’s easier for the body to absorb, with a range of flavonoids—natural compounds renowned for their antioxidant properties and existing antiviral effects.
We ensured that these combinations were safe by assessing their impact on cultured cells, confirming that they didn’t harm cell viability. When tested further, our results revealed an impressive 50-95% reduction in viral genome replication levels across a variety of respiratory RNA viruses, including the flu virus, which suggests that this combination therapy could be promising in the fight against such illnesses.
Overall, our findings highlight an innovative approach to treating viral infections that is non-toxic, derived from nature, and may remain effective against emerging viral strains.

In our evaluation of how zinc can impact flu symptoms, we observed a study that examined the effects of gargling with an antimicrobial mouthwash containing zinc and cetylpyridinium chloride.
A total of 150 individuals participated, divided into two groups: one group followed a regular oral hygiene routine with fluoride toothpaste, while the other group followed the same routine but added gargling with a mouthwash containing 0.075% zinc.
The results revealed that regular gargling with this mouthwash helped reduce the frequency and severity of upper respiratory symptoms, with participants using the mouthwash showing a 21.5% lower frequency and 11% reduced severity in symptoms.
However, it's important to note that the study did not isolate the effects of zinc, leaving questions about the specific contributions of this mineral to the overall findings. Therefore, while we can see that the mouthwash appears beneficial, we cannot definitively attribute its effects solely to zinc.

NOW is my family's favourite brand. The zinc I've used for a long time really impacts my health. Over the past year, I've not had the flu, and during the COVID-19 pandemic, I never contracted the virus. I take zinc with vitamin D3 (10000iu) and K2 (180mcg). I feel remarkably healthy and hope my experience helps others.

Shortens flu recovery

Essential for the immune system and respiratory illnesses! Zinc is a great aid for respiratory issues. Sambucus is packed with zinc, or you can opt for a synthetic variant. It helps prevent flu or colds, and if you already have one, it shortens recovery time. This mineral boosts the immune system, and it’s wise to add Vitamin C and D3 as well. These capsules are easy to swallow and don't cause an upset stomach; just ensure you take them with or after meals.

Helpful for recovery
Great for respiratory illnesses and a strong immune system. When battling a respiratory illness like flu, it helps speed up recovery. Zinc is naturally found in Sambucus, but this synthetic alternative is excellent. It is an essential mineral that, alongside vitamins C and D3, supports a robust immune system. It's recommended to take these capsules with meals, and their small size makes them easy to swallow with or without liquid.
