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.

UPDATE: My family has taken Vita C since September 2015, and I'm happy to report we haven't had any colds or flu. Essential for my uncle with COPD and my grandmother post-surgery.

The absolute best product to stop a cold! I’ve researched this extensively and have used it for a year. Dr Thomas Levy mentioned it on a podcast after having the flu; he said five packets felt as good as an IV of Vitamin C! That got my attention. I take several packets daily to ward off toxins and more if I feel a cold coming. Research shows Vitamin C is crucial in high doses, so educate yourself! Pharma can’t profit off it, hence their reluctance to promote it.

I cannot recommend it enough if you have a low immune system. Although there's no discount for buying two, I don’t mind. I tell everyone about my 'Lipo C' and how it has improved my life! I have Cystic Fibrosis, and I constantly catch colds. Since taking this once a day, I rarely get sick. Occasionally, if someone brings a cold home, I might catch it, but it's gone within a day or two—previously, that cold would have led to a two-week hospital stay. A huge blessing!

WORKS! I have been taking Lypo-Spheric Vit C for a few months. I had bronchitis last winter, which lasted too long, and then contracted Lyme disease last summer. I felt my immune system was compromised and discovered this product could help. It makes me feel better and more energetic. The real test was a few weeks ago when we returned from Italy; sick people were coughing and sneezing on the plane. My husband caught a severe cough and cold shortly after, but I didn't! As of now, I've stayed healthy, haven't caught the flu, and I still take 2 packets daily. I will see if I catch the flu that’s spreading. I almost felt unwell a couple of times but bounced back quickly. I am definitely sold on this product.
