Effective for whooping cough
This product initiated my acquaintance with iHerb when my children had whooping cough. It alleviated their condition effectively. I learned about its benefits during whooping cough and began to use it. I adjusted the dosage for my children, and they recovered faster than the doctors anticipated. It is now a staple in my first aid kit.

Forget coughs entirely
I take this myself and give it to my children at the first sign of ARVI or when those around us are ill. The combination of vitamin C, liquid zinc, and vitamin D at 5,000 works wonders! We’ve forgotten about lingering coughs and snot. This particular Vitamin C has an excellent formula at a fantastic price!
