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.

I adore this zinc! It doesn't cause any gastrointestinal side effects, which is crucial for my chronic stomach issues. I take it with vitamin C after breakfast, in 1-2 month courses during autumn and spring, and it really helps prevent me from getting poorly.

I really like this zinc. Being in picolinate form, it's absorbed even with low acidity, which is great for those over 40. It avoids gastrointestinal side effects, crucial for my chronic stomach issues. I take it after breakfast with vitamin C and in courses during autumn and spring.
