We explored the impact of high doses of Vitamin C on cold and flu symptoms in a controlled study involving 752 students. While 463 participants made up the control group and received standard treatments, the 252 in the test group took 1000 mg of Vitamin C at set intervals.
After comparing reports from both groups, we observed that those who took Vitamin C experienced less severe and fewer symptoms compared to those who did not. This suggests that Vitamin C could be a helpful supplement in managing flu symptoms.

We explored the effects of high-dose vitamin C on blood flow during inflammation caused by endotoxin. In a balanced, placebo-controlled crossover study with 36 male subjects, we examined how vitamin C administration impacted vascular function. After administering lipopolysaccharide (LPS), participants experienced flu-like symptoms and a significant drop in blood flow response.
However, we found that high-dose vitamin C improved this blood flow response, suggesting it can help counteract issues related to inflammation. This paves the way for further research on vitamin C's benefits in similar conditions.

Avoids illness permanently

This stuff is like gold. I take it as soon as I feel a scratchy throat, twice a day, and it usually helps me dodge getting sick. My wife avoided the flu this year by taking it twice a day as she fought it off. Some ingredients are also good for male reproductive health, and I’m currently using it to help recover from the flu fever.

Fights flu effectively

Great product - it works for me! I love this product, as it has kept me out of the hospital alongside elderberry. I had the flu five times last year and felt awful! Towards the end, I took this along with elderberry, three times a day as a hot tea with honey and lemon. It was delightful and helped me recover. I still take Airborne once a day in winter, and if I feel something coming on, I increase my dose. It’s the only way I stay well. Thank you, Airborne!

Avoids flu shots

Miracle product! The price for this large bottle of Airborne is fantastic. I've found this product at other retailers for smaller quantities and higher prices. These come in a sealed bottle with a valid expiration date. Taking two a day during cold/flu season keeps me from having to get a flu shot, especially before flying with sick passengers. So far, so good—three years without a flu shot and no winter colds or flu. Previously, I'd get a flu shot and end up unwell for almost two weeks. Never again. This is a great alternative for those who can't tolerate vaccinations. Highly recommend.

Fast recovery
I have never been as satisfied with a Vitamin C as I am with Airborne. Despite its slightly high price, my family and colleagues take it whenever they feel colds emerging. Remarkably, they recover the next day! When I had a bad cold, I took three daily, and by the next day, I was ready for my overseas trip. I have been stocking up on Airborne since then.

Boosts immunity
Reliable product. Airborne is essential, especially during flu season. I always place one in my kids' water bottles to ensure they take it at school. It gives me peace of mind knowing that Airborne may help boost their immunity. My children rarely catch the flu or fall ill, and I believe it's Airborne that makes the difference.
