Our family absolutely loves these Zinc lozenges. We have been using them for a couple years now. We have tried lots of different zinc options… Lots of them leave us feeling nauseous if we have not eaten first. These ones are extremely large lozenges, so it's kind of strange having them in your mouth until they melt. But once you get used to it and have them in your mouth for a few hours, you realize that your body is able to slowly absorb the zinc throughout your day. It has been the most effective zinc absorption, and heals our body from illness way more quickly than with other natural remedies. Recommend this to ALL ADULTS!
