Zinc may prevent influenza entryEpipharyngeal Abrasive Therapy Down-regulates the Expression of Cav1.2: A Key Molecule in Influenza Virus Entry. We investigated how zinc, delivered through epipharyngeal abrasive therapy (EAT), might impact the expression of a key molecule known as Cav1.2, which plays a crucial role in allowing the influenza A virus to enter cells. The study included two groups of patients: one group that received EAT, which involved scratching the epipharyngeal mucosa with a zinc chloride-treated swab, and another group that did not receive this treatment.
By analyzing tissue samples, we observed that the levels of Cav1.2 were significantly lower in the EAT-treated patients compared to those who were not treated. In fact, the expression of Cav1.2 in the patients who underwent EAT was measured to be 4.19 times lower than in the non-treated group. This suggests that the squamous metaplasia induced by EAT might help reduce the entry of the influenza virus by down-regulating this key protein.
Our findings indicate that EAT, through its zinc content, could serve as a simple and effective method to potentially prevent influenza infection by limiting the virus's ability to enter cells. Improved immunity Most Useful Review 206 people found this helpful I accepted zinc for two reasons: to strengthen my immune system and to improve my skin and hair. After suffering from the coronavirus, my health and appearance were affected. However, after taking zinc, I noticed a significant improvement in my immunity over the winter months, avoiding colds and influenza. My hair and skin also began to improve noticeably. |

Echinacea shows promise against influenzaEthanolic Extract from (L.) Moench Inhibits Influenza A/B and Respiratory Syncytial Virus Infection : Preventive Agent for Viral Respiratory Infections. We focused on how echinacea, a well-known wildflower, can combat viruses that commonly cause respiratory infections, specifically influenza A and B, as well as respiratory syncytial virus (RSV). Through a methodical approach, we evaluated the effects of a 60% ethanol extract of echinacea and its active compound, chicoric acid (CA), on these viruses.
Our research utilized various tests to measure the antiviral effectiveness of echinacea. We observed that both the extract and chicoric acid significantly reduced the infectivity of H1N1, IVB, and RSV-A in controlled experiments. Notably, our findings indicated a decrease in viral gene expression and confirmed through microscopy that echinacea's components could limit the ability of these viruses to infect host cells.
Additionally, we found that echinacea's extract and chicoric acid effectively hindered the attachment of H1N1 and IVB viruses to cell receptors, showcasing their potential utility in preventing these viral infections. With this strong set of results, we believe that echinacea could serve as a promising natural remedy or ingredient in functional health foods aimed at reducing the impact of viral respiratory infections. Effective for recovery Most Useful Review 1 people found this helpful Very effective for influenza. I have repurchased this product multiple times. My boyfriend recovered quickly after using it for just 1-2 days, which prevented a week-long illness. I recommended it to a friend whose child and husband were infected; it worked wonders for them too. Purple Daisy has now become an essential supplement in my home. When infected, I suggest taking 2 pills every 2 hours and several times daily, especially combined with vitamin C for better results. |

Vitamin C's unclear influenza impactThe Role of Some Vitamins in Respiratory-related Viral Infections: A Narrative Review. We explored the relationship between vitamin C and influenza, delving into various studies conducted from 2000 to June 2021. In our analysis of the research, we found eleven studies that specifically examined the effects of vitamin C on influenza.
While some of these studies reported positive outcomes, we should note that the isolated benefits of vitamin C can be hard to determine. This is primarily because some studies included additional treatments, making it difficult to draw definitive conclusions about vitamin C alone.
Overall, we observed that while there is some interest and preliminary evidence regarding the efficacy of vitamin C in preventing or treating influenza, its stand-alone effectiveness remains somewhat unclear.
Continued research should help clarify how much vitamin C can truly contribute to combating influenza. Boosts immunity Most Useful Review Excellent for boosting immunity and accelerating recovery from influenza. Its quality is high. I take one or sometimes two pills after eating. |

Elderberry's limited flu efficacyEchinacea and elderberry-should they be used against upper respiratory tract infections during pregnancy? We explored the effectiveness of elderberry in treating influenza, drawing from clinical trials that examined its impact. Over the years, three specific trials involving different elderberry preparations were conducted, with a total of only 77 participants receiving treatment. While these trials concluded that elderberry could be effective against influenza, the very limited sample size raises questions about the robustness of these findings.
Additionally, it’s important to note that in the larger context of herbal remedies, there isn’t enough comprehensive evidence to fully endorse elderberry as a reliable treatment. Though the studies indicated some level of efficacy against the flu, the small number of participants means we must approach these results with caution.
Given that substantial evidence of safety and effectiveness is lacking, it wouldn't be prudent to rely solely on elderberry for influenza treatment, especially among vulnerable groups like pregnant women. Shortened flu duration Most Useful Review 3 people found this helpful Awesome! Elderberry is a superb aid for health. It boosts the immune system, relieves flu symptoms, and reduces duration.

 NOW Foods, Omega-3 Fish Oil, 1,000 mg, 180 EPA - 120 DHA, 200 Softgels | | |
Docosahexaenoic acid's antiviral effectsAnti-inflammatory and anti-virus potential of poxytrins, especially protectin DX. We explored the potential of docosahexaenoic acid (DHA) and its derived compound, protectin DX (PDX), specifically in the context of influenza virus replication. The research highlights how poxytrins, which are dihydroxy derivatives formed from PUFA, may play a significant role in addressing inflammation and viral issues due to their unique structure.
Protectin DX is known for its ability to inhibit the activities of cyclooxygenase (COX), which are linked to inflammatory processes, as well as reducing the formation of harmful reactive oxygen species (ROS). Interestingly, we observed that PDX also has the potential to limit the replication of influenza viruses by interfering with their RNA metabolism.
While the study emphasizes this unique dual action, it should be noted that it primarily focuses on the effect of PDX alone, without comprehensive exploration of combined effects with other treatments. Regardless, the findings suggest a promising pathway for using DHA-derived compounds in viral mitigation, particularly relating to influenza.

Vitamin D3 may reduce influenza severityOral Supplementation of the Vitamin D Metabolite 25(OH)D Against Influenza Virus Infection in Mice. We aimed to understand how oral supplementation of 25-hydroxyvitamin D, a key metabolite of vitamin D3, influences influenza A virus infection in mice. In our study, mice were given a diet enriched with a high dose of 25(OH)D before they were exposed to the influenza virus.
The results were promising. Mice that received the vitamin D3 supplement showed significantly lower viral levels in their lungs compared to mice that were fed a standard diet. Furthermore, we noticed a decrease in certain pro-inflammatory cytokines, namely IL-5 and IFN-γ, which are involved in the body's inflammatory response to infection. Importantly, we found that the anti-inflammatory cytokines did not see a significant increase.
These findings suggest that 25(OH)D can help to suppress excessive inflammatory responses and may reduce both the replication of the virus and the overall severity of influenza in this mouse model. It opens the door to further exploration on vitamin D3's role in combating influenza in humans. Improves immunity Most Useful Review 2 people found this helpful Vitamin D3 is essential for everyone. I recommend this manufacturer to my friends. It's particularly important for office workers living in areas with limited sunlight. It enhances immunity, supports bone health, and lowers the risk of ARVI and influenza. My family takes it for prevention with 2,000 IU every other day, and daily when ill. |
