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.

These supplements help my ragweed allergies significantly when I wake up choking at night. Combined with Flonase and Allegra for severe instances, these are easy on an empty stomach and effectively reduce mucus without side effects. Highly recommended!

An excellent form of vitamin C! It aids in fighting colds and reduces allergies while promoting collagen production. With today's depleted soils, supplements like Garden of Life's are essential. I prefer natural vitamins, free from synthetic additives, and this product meets that standard well.

The family doctor suggested ascorbic acid and sodium ascorbate to combat adrenal fatigue and boost immunity. This natural source, rich in bioflavonoids, enhances absorption. I tolerate it well, experiencing fewer allergy symptoms, which was unexpected.

Natural vitamin benefits
Ascorbic acid, a chemically derived form of vitamin C, needs large doses that aren't well absorbed and can cause allergies for some. In contrast, vitamin C from natural sources is easily utilised by the body, gently supporting immunity without harm. Although it's pricier, smaller doses are effective without quick disposal. Unfortunately, real natural vitamins cannot be inexpensive.
