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.

Prevention effectiveness
This is the best zinc on iHerb! It's challenging to find. If it appears, don't hesitate. Firstly, it's from Solgar, a trusted brand. Secondly, it's a chelated form, making it better absorbed. My family and I take it regularly. When I contracted Covid, I had no fever, cough, or sore throat. Though I was fatigued for five days, I recovered quickly. I believe the zinc, alongside vitamin D, helped tremendously. Those with my weight often face complications, so please prioritise prevention.

Cold suppression
This supplement is excellent! It effectively manages the initial stage of a cold. A mild zinc deficiency could lead to frequent colds, flu, and chronic cough. Chelated forms of zinc are better absorbed, making this product a great choice.
