Researchers tested whether zinc acetate could help people suffering from persistent, hard-to-treat cough. In this randomized, placebo-controlled pilot study, 34 participants received either zinc acetate or placebo for 6 weeks, with improvements measured using four different cough and quality-of-life scales.
While zinc successfully increased serum zinc levels in treated participants, both groups improved similarly across all measures. The improvements in cough symptoms and quality of life were too small to meet clinically meaningful thresholds, suggesting zinc acetate offers no real advantage over placebo for chronic cough sufferers.

Dietary vitamin C reduces smoking-related cough
Dietary vitamin C intake is inversely related to cough and wheeze in young smokers.
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
Consumption of fresh fruit rich in vitamin C and wheezing symptoms in children. SIDRIA Collaborative Group, Italy (Italian Studies on Respiratory Disorders in Children and the Environment).
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.

Reduced illness frequency
Happy as a boa constrictor! This perfect combination of components supports my body during colds and pandemics. I have poor immunity and previously got sick every month, often needing antibiotics for my chronic cough. However, these magical gummies have helped me enjoy the off-season and mostly forget about snot, cough, and sore throat.

Zinc acetate ineffective for chronic cough treatment
Efficacy and tolerability of zinc acetate for treatment of chronic refractory cough: pilot randomised futility trial.
