Effectiveness of Vitamin C on Colds
We explored the effects of vitamin C on the common cold and pneumonia by examining a range of studies. Interestingly, research on animals suggests that vitamin C may have protective effects against infections. However, when it comes to preventing colds in the general population, taking more than 1 gram of vitamin C per day didn’t show significant benefits.
But there's a twist! Participants engaged in heavy physical activities saw their cold incidence reduced by half with vitamin C supplementation. Additionally, regular intake of 1 gram or more daily was linked to a 15% decrease in cold severity. While some therapeutic trials showed inconsistent results when vitamin C was taken after cold symptoms appeared, two studies did indicate that larger doses (6-8 grams per day) could effectively shorten the duration of colds compared to lower doses.
Our investigation also looked into pneumonia, but the studies were conducted in unique settings, such as a boarding school and military recruits. This makes it hard to generalize the findings to the wider population. Yet, some trials suggested benefits for pneumonia patients. Finally, the role of vitamin C in treating COVID-19 and sepsis remains unclear, with mixed results.
Given that vitamin C seems to alleviate symptoms and shorten the duration of colds, while being safe and affordable, it might be worth considering a dose of 6-8 grams per day to see if it helps at an individual level.

We explored the effects of ascorbic acid, commonly known as vitamin C, on cold tolerance in tomato seedlings. In our study, we discovered that applying vitamin C significantly boosts the seedlings' ability to handle cold stress.
By enhancing the antioxidant defense system, vitamin C treatment increased the enzyme activity in the seedlings' leaves. Additionally, it raised levels of important compounds such as proline, sugar, and abscisic acid, all of which play crucial roles in plant stress responses.
Our observations showed that vitamin C also protects the photosynthesis system of tomato seedlings. This implies that it helps maintain chlorophyll function, which is critical for the plant's overall health, especially under cold conditions.
Moreover, we found that vitamin C treatments led to increased expression of genes linked to antioxidant enzymes and cold response mechanisms. Overall, our findings suggest that exogenous vitamin C is a beneficial approach to improve cold tolerance in tomatoes and may provide helpful insights for farmers looking to cultivate hardier varieties during colder months.

My husband's serious health issues led us to discover the benefits of high-dose Vitamin C. While he was hospitalised, I managed to administer this product through a feeding tube, which accelerated his recovery. Each day, he received a potent dose of vitamin C, and ultimately, he improved much faster than expected. We're now using it to guard against any future respiratory ailments, including colds and flu. I highly recommend learning more about this option for those with compromised health.

Thanks to Tim Ferriss’ recommendation, I bought this Vitamin C on impulse. About a month later, when my mother was hospitalised, I mixed doses of this product in her water, which helped her fend off a cold. When my son began coughing, I administered it to him, and he overcame his symptoms quickly, avoiding the cold that was affecting his classmates. My partner also experienced a month-long cough, but thanks to this product, he recovered remarkably in just a few days. This Vitamin C has proven invaluable in protecting us from illness.

Having taken this product for almost a year, I’m impressed with its effectiveness. Despite frequent exposure to sick individuals, I haven't caught a cold since starting on it. I take it twice daily, which has also noticeably improved my healing speed. I attribute my resilience against colds to its high bio-availability, absorbing a substantial percentage of the vitamin C. This product has truly transformed my health!

This past winter's flu season was relentless and knocked me out for two days. I sought a Vitamin C IV treatment but opted for this product instead. After starting it, I noticed my runny nose disappeared by the fourth day, and my cough resolved by the third week. I usually suffer from lasting coughs, but this Vitamin C helped me recover quickly. Now, I take it at the first sign of illness and highly recommend it.

Cold relief

I was struck by a cold/flu that began on Christmas day and persisted painfully. After trying various remedies to no avail, I ordered Lypo Vitamin C, and within just two days, I felt revitalised. It's important to understand that this product, encasing the vitamin C in liposomes, won't mix effectively with water. I recommend taking it on an empty stomach for the best outcome. It’s been very helpful for reducing my cold symptoms, although it's still just a potent vitamin C supplement and not a cure-all.
