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.

I love this product. For years, we've gotten sick while travelling—upper respiratory issues after returning home. We took Emergen-C before the last two trips, and no illness occurred. Although I’m not keen on the fizziness, I let it sit to fizz out before drinking. We started taking it two weeks prior to our trips, and it seems to have minimised the severity of potential cold symptoms.

EMERGEN-C does exactly what it advertises – a great taste and reasonable price. I purchased this in late October after experiencing bad cold symptoms. Upon taking a packet, I was pleasantly surprised to find that within 24 hours, my symptoms (sore throat, body aches, and sinus pressure) significantly improved. I've tried other supplements without noticeable effects, but EMERGEN-C really helps to boost the immune system. I will buy it again and highly recommend it.

Clears up colds
3 people found this helpful
Worth every penny. Initially, I was sceptical about Emergen-C after reading an online review on how it helped clear up a cold in two days. With the flu season approaching, I decided to give it a try. This product works as promised, alleviating colds, sore throats, and tummy bugs. The sachets contain a potent powder that fizzes when mixed with water. Wait for the bubbles to settle before stirring to avoid a mess. It is quite palatable, even for those who aren't fond of berry flavours; mixing it with a bit of juice can enhance the taste.

It's quite sweet, but I feel the effect. While travelling in the US with a cold, a local introduced it to me. I took it for hydration and vitamin boost, which helped me recover quickly. It's also great for keeping hydrated on the hottest summer days.

Keeps me healthier

Keeping the colds away has been my experience with this product. As an educator, I tend to get sick easily, but drinking a packet daily has truly helped me stay healthier during cold and flu season, seemingly shortening any colds. I adore the raspberry flavour. It’s also convenient having it delivered monthly. My family are fans as well, and I recommend this drink to friends and family since I firmly believe it works.

Family protection
I have used this immunity product for many years. In a small office where colds spread, I would take it to prevent getting sick. I bought it for my grandchildren to provide them with good Vitamin C, D, and Zinc supplementation when illness struck their family. I believe it helped as two of the five never got sick, and everyone else recovered quickly. The flavour is nice too.
