Useful when you start caught a cold

Posted by 5011174210337999708 on Mar 13, 2017 | Verified Purchase

I've been using this for 3 years. Whenever I caught a cold with sore throat, I immediately take 1 pill in the morning and 1 pill at night. It helps recover faster.

Thanks for your feedback!

Tampered product

Posted by stephscoleman on Aug 23, 2016 | Verified Purchase

The cap was sealed shut down with plastic, which I had to cut into in order to untwist the cap. The moment the cap was untwisted, the inner seal which normally requires force to pull open was wide open, and the inside cotton wool was pushed aside. This meant the product was tampered with. I am nervous and not sure what to do. First time I received a tampered product from iherb. First time I ordered this brand. I do not have any notice from customs they have reviewed the contents either. All points to issues around processing from Jarrow.
