Quick effect
Quartztin was prescribed by my doctor for my two-month battle with whooping cough. It worked quickly; within two days, I was sleeping soundly and my cough had vanished completely in a week. I even started giving it to my daughter, and by day three, her cough was gone too.

Effective for allergies
I bought this product after seeing Dr. Berg on YouTube, hoping it would ease my whooping cough due to allergens. Miraculously, within two days my wheezing was gone, and after a month, my cough vanished completely. It's more effective than any prescription I’ve tried.

Better than syrup
I ordered this supplement after my daughter suffered from persistent whooping cough. Traditional remedies helped temporarily, but after starting this, she felt better and eventually overcame the cough. It's far better than the usual cough mixtures that cause drowsiness.

Safe and efficient
After three years of searching for a safe solution for whooping cough and respiratory issues from flu and COVID, I found this product to be effective. It actually works and helps reduce inflammation with added bromelain.
