This supplement (the contents inside of the capsules) seems to be a 5-star product. However, I ordered the Zinc (and Vitamin C) two months ago, and I’ve been apprehensive about taking these regularly due to a chemical odor that came from the inner seal. When I opened both bottles, there was a very pungent VOC/chemical smell, and I realized that the culprit was the inner safety seal (that you peel off after removing the cap). Unfortunately, the chemical smell had transferred onto all of the capsules that were inside of the bottle. I’ve purchased quite a few high-quality supplements over the past several years, and have never come across an inner seal that smelled like VOCs. The fact that those chemicals transferred onto the capsules is concerning, so I’ve only used the Zinc and Vitamin C sparingly. I really want to use them regularly, and I also want to order the Cranberry Extract, but can’t due to that issue. I really hope that Triquetra changes the inner seal to something that’s made with food-safe (and therefore odorless) materials. If they do, I would absolutely order multiple supplements from them on a regular basis.
