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've been taking this vitamin for a while, and I’m pleased to say I haven't been as ill. The information I found indicated it’s excellent for colds and flu. My chronic cough has lessened, and my appetite has improved.

If you’re considering this product, I highly recommend it, especially for kids. My child had a runny nose, and after giving him zinc, it cleared up quickly. I experienced a chronic cough myself and found zinc to be effective as well.

After a month of taking this vitamin, I feel significantly better. I previously suffered from chronic fatigue, but now I have much more energy. The only drawback is its strong minty taste without alternative flavours.
