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.

Immune boost noticed
25 people found this helpful
Fantastic! This product, recommended by a chap in America, promises an 'immunity shock BOOST!' I bought six on 12th October and have been taking four daily. It’s splendid and I’ve already seen improvement in my immunity; my morning sniffles and sneezing have stopped, and my allergies to dust and pet hair have improved significantly. I’ll take these for six months to enhance my immunity further. The time-release formulation is excellent, delivering Vitamin C throughout the day. Though they aren't the most enjoyable to consume, the benefits are considerable. I wholeheartedly recommend this product.

One capsule per day suffices! This long-acting formulation aids in the absorption of Vitamin C throughout the day. I take one daily without any issues of allergies, and it absorbs well. If swallowing is difficult, the capsule can be opened and its contents emptied.
