I would say that my favorite product is the Redd Remedies SinuZyme. This product has worked well for me over the last couple of years. I have had sinus issues my whole life. No matter what product I tried none of them would help. Since taking 1-2 capsules of SinuZyme every day I have not needed to miss work and I have avoided over-the-counter medicines. This is my favorite and go to supplement product every day.
