“These zinc lozenges taste great. The lemon flavor is good. I like that there are no artificial colors flavors or preservatives in them. Great for vegetarians and those who need gluten-free. A great way to add some vitamin C and zinc when you need it. A great way to get some additional nutritional support. A good deal and highly recommended!“

"I'm always looking for new supplements to help keep my body running 100%. One of those things I have looked into has been Quercetin - since it is an antioxidant found naturally in leafy greens, tomatoes and berries - it plays an important role in fighting free radical damage. I can't wait to see how great my body feels with the continued use of this product."

“This product is like a two in one solution. First and foremost the zinc helps with immunity support and also helps you get better quicker when you are sick. When you're not sick it can be taken as a preventative measure. Since it's a lozenge there's no swallowing pills so if you have issues with that, a lozenge is a great alternative method of delivery for the zinc. Second the lozenge is flavored and aids in relieving sore throats. It's a great product in my opinion.“

“I absolutely love these zinc lozenges. I have caught a bad cold the past couple days & these came so fast that I have been using these twice daily to aid in ridding these cold symptoms! These lozenges have ALREADY began to lessen the severity of my symptoms, so i have no doubt these are excellent quality!!!!“
