We examined the effects of vitamin C on pneumonia caused by the influenza virus, specifically the H1N1 strain, in mice under stress. The study found that when exposed to restraint stress, the mice experienced increased mortality and more severe pneumonia symptoms.
However, by giving them oral vitamin C at doses of 125 and 250 mg/kg, we observed a significant reduction in these severe outcomes. Vitamin C seemed to modulate the expression of certain genes related to the immune response, such as MAVS and IRF3, and increased the expression of NF-κB, which plays a key role in the body's antiviral defense.
Our research suggested that vitamin C's protective effects might stem from its ability to inhibit excess cortisol production in the adrenal gland, which is often elevated due to stress. By lowering cortisol levels, vitamin C may help reduce susceptibility to influenza infections, making it a potential ally during the flu season, especially for those experiencing stress.
Through these findings, we highlighted a new mechanism for how vitamin C can be beneficial during influenza infections, particularly for those who are feeling overwhelmed.

Zinc treatment impacts flu virus entry
Epipharyngeal Abrasive Therapy Down-regulates the Expression of Cav1.2: A Key Molecule in Influenza Virus Entry.
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.

Prevents illness
This complex is excellent for cold prevention during the season. Our whole family uses it, and from September to December, none of us fell ill, despite a surge of influenza and SARS in schools and nurseries. I’m very pleased to have discovered this complex and recommend it to everyone!
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.

Immune booster for flu treatment
Red ginseng and vitamin C increase immune cell activity and decrease lung inflammation induced by influenza A virus/H1N1 infection.
We set out to discover how red ginseng and vitamin C work together to enhance immune cell function and fight off viral infections like the flu. In our investigation, we treated human immune cells and specific types of mice unable to produce vitamin C, looking closely at their reaction to influenza A virus/H1N1.
Our findings were quite promising. We observed that both red ginseng and vitamin C elevated the activation levels of immune cells, particularly T-cells and natural killer (NK) cells, known for their vital role in combating viruses. This combination not only helped boost immune cell activity but also reduced lung inflammation caused by the influenza virus, which is crucial for better survival rates during infections.
In cases where vitamin C levels were low in a specific mouse model, we noted that the added nutrients significantly improved their condition. They experienced reduced viral load and inflammation in their lungs after receiving red ginseng and vitamin C, compared to those without this supplementation. These insights suggest that while red ginseng and vitamin C collectively support immune health, the interplay of these substances can be crucial in managing flu infections effectively.

Quick recovery
Whenever I sense the onset of a cold or flu, I quickly reach for a zinc capsule. By the next morning, I'm healthy and happy as usual.
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.

Zinc's impact on flu symptoms
Zinc and Respiratory Viral Infections: Important Trace Element in Anti-viral Response and Immune Regulation.
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.
