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 usually ordered different brands of zinc picolinate, but when they became unavailable, I found this one. I bought five packs as the chelated form is highly digestible and the dosage is excellent. It effectively prevents colds—whenever I feel the onset of sore throat and runny nose, I take two tablets daily for two to three days, and I recover quickly. With Covid, it’s advised to take 50-100 mg daily.
