Works

[This review was collected as part of a promotion.] I didn't taste anything because I was stopped up . It did help clear me up within 24 hours. I only had to take 2 doses and I was getting better by the day.

Very effective

[This review was collected as part of a promotion.] My dad actually got sick as soon as this came in. Easy to read instructions on the packaging. Easy dosage and the consistency of feeling relief was fast for him.

Great

[This review was collected as part of a promotion.] I got these a few weeks ago for my daughter to try out and they seem to work well and fast. My daughter works in a daycare and these helped her get rid of symptoms in just a few days.
