We conducted a thorough evaluation of how vitamin C, when combined with pleuran, impacts asthma control and respiratory issues in children suffering from perennial asthma. The study was meticulously designed as a double-blind, placebo-controlled trial involving 230 children aged 7 to 17 years. This means that neither the participants nor the researchers knew who was receiving the active treatment or the placebo, ensuring the findings were reliable.
The results were promising, especially for children under 12 years. They showed significant improvements in asthma control compared to those receiving only the placebo treatment. Meanwhile, older children (12 years and above) experienced fewer respiratory infections with the combination treatment. Overall, by the end of the 48 weeks, a majority of children on the pleuran and vitamin C treatment reported better asthma control compared to those on the placebo.
While the combination of pleuran and vitamin C was indeed beneficial for managing asthma, we must note that the study did not specifically isolate the effect of vitamin C alone on allergies or asthma. Thus, it is hard to draw definitive conclusions about vitamin C's effectiveness independently from pleuran. However, the approach suggested that using these supplements together could offer a helpful boost in managing asthma symptoms.

Controlled allergies

After suffering from allergies since I was 12, I found that taking Vitamin C regularly provides control over my symptoms. I previously experienced multiple sinus infections each year that other treatments couldn’t alleviate. In contrast, vitamin C has been the only solution that worked. I sometimes take more than the recommended dose, but it helps keep my sinuses clear. I now also take calcium and magnesium to relieve side effects.
