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.

We examined how serum levels of vitamin C could influence mortality rates from influenza and pneumonia. The study analyzed data from 7,428 participants aged 45 and older, utilizing information from the National Health and Nutrition Examination Survey (NHANES-III).
Through our research, we discovered that vitamin C, along with other antioxidants like carotenoids, showed a nonlinear relationship with mortality from these respiratory illnesses. Specifically, those in the third quartile of serum vitamin C displayed a lower risk of dying from influenza or pneumonia compared to those in the lowest quartile, with a hazard ratio of 0.38.
This implies that having a moderately high level of vitamin C may help reduce the risk of mortality from these diseases. However, the protective effect seemed to weaken for those in the highest quartile of vitamin C, suggesting a more complex relationship.
Overall, this study highlights the potential benefits of maintaining healthy levels of vitamin C in the blood, indicating that antioxidant intake may positively influence mortality risk among adults facing influenza or pneumonia. Nevertheless, more research is needed in diverse populations to confirm these findings and explore their implications further.

We systematically reviewed how vitamin C affects respiratory tract infections (RTIs), including influenza. This involved analyzing results from numerous studies to understand how effective vitamin C is in either preventing these infections or alleviating their symptoms.
Our findings reveal that vitamin C supplementation can reduce the risk of RTIs, with a reported risk ratio of 0.96. This means that taking vitamin C may lower the chance of getting an RTI compared to not taking it at all.
Additionally, we observed that vitamin C can help shorten the duration of symptoms by approximately 9%, making recovery from a potential influenza infection a bit quicker. Interestingly, the benefits of vitamin C seemed to be more pronounced among men and in populations from middle-income countries, compared to women and those in higher-income areas.
While the results are promising, it’s essential to note that vitamin C alone might not be a complete solution for preventing influenza. More research is necessary to fully understand its effectiveness, particularly in light of other emerging viruses and health challenges.

Great help not only for colds and influenza! I recall my mother always giving us sour yellow vitamins for colds, which I cherished. Many know that vitamin C is effective against influenza and colds, and few realise it also combats allergies! For prevention and treatment of influenza, I take one capsule (1000 mg) morning and evening for the first two days. This truly hits viruses hard! When cold season arrives, everyone in my household takes one capsule daily. As a result of this preventative measure, we've fallen ill much less frequently, and if we do catch something, our colds are milder and pass quicker. As someone with severe allergies, I take 1000 mg of this vitamin daily, and during spring-autumn, I don’t experience any allergy symptoms. I don’t get colds at all. Highly recommend it! Stay healthy and happy!

We investigated the potential of a unique formulation combining vitamin C with a complex of alkaloids to combat the H1N1 influenza virus. Our approach involved creating nanoparticles that encapsulate both the alkaloid-rich fraction and ascorbic acid (vitamin C) to enhance the water solubility and bioavailability of these components.
The results were promising, showing that our formulated nanoparticles had a significant selective antiviral effect against the H1N1 virus, achieving an IC50 of 2.7 μg/mL. Notably, this effect was observed without harming the host cells, suggesting that the treatment could be both effective and safe.
However, it's important to note that while the presence of vitamin C in the formulation seems beneficial, we also included other active ingredients, making it difficult to assess the isolated impact of vitamin C alone. The combination of these elements appears to contribute to the overall effectiveness against influenza.
In summary, our findings indicate that this new delivery system might be a promising avenue for treating influenza viruses, with vitamin C playing a supportive role among other powerful components.

We investigated how an acupoint injection containing vitamin C and B complex affected pneumonia triggered by the influenza A virus in mice. In our study, we used 60 male mice that were divided into six groups to evaluate the effectiveness of the treatment. One group received the vitamin solution through acupoint injections, while others received it through different methods, including intraperitoneally and at non-target points.
Our findings indicated that the acupoint injections helped reduce inflammatory responses and oxidative stress in the lung tissue of the mice. We observed improvements in survival rates and longer survival times, despite no significant impact on the viral load in the lungs. This suggests that while vitamin injections can offer some protective benefits, they do not eliminate the virus itself.
Overall, while we found some positive effects of using the V+VCo solution, the results highlight the complexity of treating viral infections like influenza. It seems that vitamin C, combined with other vitamins, can be beneficial for managing symptoms, but it doesn't directly attack the virus.

Vitamin C is essential for activity, vitality, and immunity. By taking it daily, you’ll notice a significant difference and reduce the frequency of cold and influenza symptoms, possibly to just once or twice a year. The company is reputable for its high-quality products, and I trust everything stated on the box and in the description.
