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.

They help lessen my allergies. I experience itchy eyes, and this reduces that sensation. Although the effect doesn't last as long as an antihistamine, I feel better taking grape seed as it's a natural alternative.

Sadly, I experienced digestive upset with this product. Starting with just one pill every other day, I felt very nauseous. I hadn’t changed anything else in my diet, so it must have been these. I was hoping it would help with seasonal allergies, but it didn’t.

I haven't noticed any benefits so far. These are quite expensive, and I expected to feel results by now. There's been no help with my allergies whatsoever.

Dosage adjustments suggested
I take GS for allergies - just one daily. During high allergen periods, I'll take up to four. Recently, I read that taking GS with B-complex and InositolCholine can enhance amino acid synthesis efficiency. It's remarkable how GS impacts enzyme production.
