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.

Euglena extract aids flu defense
Antiviral Activity and Underlying Action Mechanism of Euglena Extract against Influenza Virus.
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.

My go-to remedy for sniffles! When I feel a cold or flu coming on, I take zinc with vitamin C and D3, and by the next day I'm well again. It works like a charm.
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.

Magical effect
Great! During cold and flu season, one capsule acts as a preventive measure against viruses! It works magically!
The flu, short for influenza, is a contagious respiratory illness caused by influenza viruses. It affects the nose, throat, and sometimes the lungs, leading to a range of symptoms that can vary in severity. Common symptoms include fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue. The flu can lead to serious complications, particularly in vulnerable populations such as young children, the elderly, pregnant women, and those with underlying health conditions.
The flu virus spreads primarily through respiratory droplets when an infected person coughs, sneezes, or talks. It can also be transmitted by touching surfaces contaminated with the virus and then touching one's face. Vaccination is the most effective way to prevent the flu, and the vaccine is typically updated annually to provide protection against the most common circulating strains. In addition to vaccination, practicing good hygiene, such as frequent handwashing and respiratory etiquette, can help minimize the risk of infection.
Zinc is a versatile metal known for its various applications in industry and health. It is a bluish-white metallic element represented by the symbol Zn and atomic number 30 on the periodic table. Zinc is primarily used for galvanizing steel to prevent rusting, in the manufacturing of alloys, and as a component in batteries. Additionally, zinc plays a crucial role in biological processes, making it an essential trace element in the human diet. It is involved in immune function, protein synthesis, wound healing, and DNA synthesis, highlighting its importance in maintaining overall health and well-being.
Zinc has been studied for its potential benefits in managing cold and flu symptoms, and there is some evidence to suggest that it may help reduce the severity and duration of these illnesses. Several clinical studies have indicated that zinc supplements can shorten the duration of cold symptoms if taken within the first 24 hours of their onset. While zinc may not necessarily prevent you from getting the flu, it could aid in alleviating symptoms and supporting your immune system during illness.
It's important to consider the appropriate dosage and consult with a healthcare provider before starting any supplementation, as excessive zinc intake can lead to adverse effects. Zinc lozenges and supplements can be helpful, but they should be part of a broader approach to flu prevention that includes vaccinations, maintaining a healthy lifestyle, and good hygiene practices. If you experience flu symptoms, it's always a good idea to consult a healthcare professional for tailored advice and treatment options.
Based on user reviews, many individuals indicate that they begin to see results shortly after starting the zinc supplement, particularly when taken at the onset of flu symptoms. For instance, one user mentioned that symptoms often subside within three days of taking zinc and other vitamins, preventing complications like the need for antibiotics Read Review. Another review emphasized a quick effect, stating that at the first signs of a cold, the combined use of zinc and other supplements had an immediate positive impact on their health Read Review.
Additionally, some users advocate for higher dosages during the initial days of feeling unwell, which they report leads to quicker relief from symptoms Read Review. Generally, it seems that users experience varying results, but the consensus is that zinc can be particularly effective within the first few days of usage, especially if taken promptly at the first signs of illness.
The research surrounding zinc and its potential benefits for flu symptoms and prevention is quite promising. A study demonstrated that gargling with a mouthwash containing zinc may significantly reduce the frequency and severity of upper respiratory symptoms among participants. Those using the mouthwash reported a 21.5% reduction in the frequency of symptoms, alongside an 11% decrease in severity, suggesting a beneficial effect, although the specific contribution of zinc remains uncertain [1]. Additionally, zinc plays a key role in immune support, potentially reducing the viral load during flu infections and accelerating recovery [5].
Further assessments have shown that zinc, particularly in combination with other natural compounds, could decrease the infectivity of respiratory RNA viruses, including the flu virus. In one study, this combination therapy led to a remarkable 50-95% reduction in viral genome replication levels [3]. Moreover, zinc has been identified as a critical element in enhancing the body's defenses against influenza, especially in formulations like Euglena extract, which has demonstrated inhibitory effects against various flu strains [4]. Overall, these findings suggest that while more research is needed to isolate zinc's specific contributions, there is empirical support for its use in mitigating flu symptoms and enhancing overall immune health.
Based on user reviews, many individuals have reported significant improvements in their symptoms when taking zinc, especially at the onset of colds and flu. Users frequently mention that escalating dosages during the early stages of sickness can lead to rapid alleviation of symptoms. For example, one reviewer shared that increasing the zinc intake to three capsules resulted in easier recovery almost immediately Read Review. Another user highlighted the effectiveness of taking zinc with other supplements, creating a synergistic effect that helped them avoid flu and cold entirely during the winter season Read Review.
In addition to acute relief, many users have noted long-term health benefits from regular zinc intake, including enhanced immunity, better skin health, and improved recovery from minor injuries Read Review. Some have even experienced restored senses, such as smell, after suffering from viral infections Read Review. Overall, while individual results can vary, the general consensus among users appears to favor zinc as an effective supplement for both preventing and managing cold and flu symptoms.
Users have reported positive experiences when combining this zinc supplement with other vitamins, particularly vitamin C and D. Many individuals highlighted a synergistic effect that enhanced their immune response and helped them avoid flu and colds.
