Dietary vitamin C reduces smoking-related cough
A survey of 4,300 young Norwegian adults examined whether dietary vitamin C intake relates to respiratory symptoms like cough and wheeze. Researchers estimated vitamin C consumption through questions about orange juice, oranges, potatoes, carrots, and tomatoes over the past year.
Among current smokers, those consuming more dietary vitamin C (395+ mg/week versus under 209 mg/week) showed reduced odds of morning cough and chronic cough. The protective effect was even stronger for ex-smokers experiencing wheeze. These benefits held true even after excluding people taking vitamin C supplements, suggesting the effect comes from food sources themselves.
The findings suggest that vitamin C's antioxidant properties may help counteract oxidative stress caused by smoking, potentially easing respiratory symptoms in smokers specifically.

Vitamin C fruit reduces childhood wheezing effectively
A large-scale study involving nearly 19,000 Italian children aged 6-7 years examined whether eating citrus fruits and kiwis—both rich in vitamin C—could reduce respiratory symptoms like wheezing and chronic cough. Parents reported their children's fruit intake and respiratory health through standardized questionnaires, with a subset of over 4,100 children followed up one year later.
The findings were striking: children eating vitamin C-rich fruit five to seven times weekly showed significantly lower rates of chronic cough compared to those eating it less than once weekly. Notably, even modest consumption of just one to two servings per week offered protective benefits. The effect was particularly pronounced among children with a history of asthma, with weekly fruit eaters experiencing less than half the wheezing incidents of infrequent consumers.

Prevents cough
Thumbs up for this Vitamin C. I love it as the dosage is just one tablet a day. It suits me well since it isn't acidic for my stomach. It helps keep flu and cough at bay.

Suppresses symptoms
This product is a high-dose Vitamin C. I typically take one pill daily for maintenance. After using it, I feel less prone to catching a cold. If I experience cold symptoms like chronic cough, runny nose, or discomfort, I adjust the dosage accordingly. It effectively suppresses symptoms.
