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.
Among all the compounds we evaluated, one stood out: the 2,3-O,O-dibenzyl-6-deoxy-L-ascorbic acid-betulinic acid conjugate. It displayed significant anti-influenza activity with an effective concentration (EC50) of just 8.7 μM and was not toxic to the cells used in our testing. This suggests that combining vitamin C with these triterpenes might enhance their ability to fight the flu virus, marking an exciting avenue for further research.
We also discovered that this particular compound acts early in the influenza lifecycle, interfering with the virus's ability to attach to cells. We confirmed this by observing that it inhibited the hemagglutination—a crucial step that allows the virus to spread. Our findings indicate that L-ascorbic acid-conjugated triterpenes hold promise as potential anti-influenza agents, specifically targeting viral entry and enhancing the effectiveness of treatment strategies.
In this study, we focused on five different compounds that are structurally distinct from sialic acid, which is the natural substrate of neuraminidase. Among those tested, vitamin C was one of the compounds alongside others like acetyl phenylalanylmethionine and propanoic acid derivatives. We found that these compounds inhibited NA activity, but the degree of inhibition varied.
Notably, the inhibition we observed was in the millimolar range, which suggests that while there is some effect, the affinity of vitamin C to inhibit neuraminidase is moderate compared to the reference drug zanamivir. The IC values for the compounds ranged from 6.4 to 73 mM, indicating that they are not as potent as zanamivir.
Overall, our study presents vitamin C and other small organic molecules as potential lead compounds for developing new neuraminidase inhibitors, even if vitamin C’s impact on flu remains to be clarified as part of a broader analysis of multiple compounds.

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.

Frequently Asked Questions
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.
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a critical role in numerous bodily functions. As an essential nutrient, it contributes to the growth and repair of tissues in the body, and it is vital for the production of collagen, an important protein that helps maintain skin, cartilage, tendons, ligaments, and blood vessels.
