I've developed terrible allergies the last few years, and really struggle when things are in bloom. Sinus Shield was a gamechanger for me and made even the worst days more normal. It's part of my daily routine now, and I've somehow escaped Covid and Flu bugs the last six months as well. Thanks so much!
