Zinc acetate ineffective for chronic cough treatment
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.

Prevented illness
I took these zinc supplements consistently before travelling internationally, where the flu was prevalent. Despite being surrounded by people sneezing and coughing, I never fell ill. I have an autoimmune condition and rely on injections for psoriatic arthritis. I trust New Chapter for their whole food-derived products and will never be without zinc again. They are of good quality and of average size, suitable for me.

Cough relief
I coughed for a long time and doubled my zinc intake. After two days, my chronic cough was relieved by more than half.
