For sinus, this is the best formula that I've tried. I live in an area with pollen and mold, and my sinuses tend to over-react and cause pressure and pain from sinus to jaw. This formula kicks that issue within 48 hours. I keep it on hand year round.

I always keep this on me because its a quick pick me upper when needed!

This is absolutely the best thing I have found to knock out any of my sinus issues.

This product is great for head cold really helps clear you out

I can’t believe how well and how quickly this works!! I have a sinus infection and with the first dose I already felt a difference. So GRATEFUL I found this product. I saw a lot of comments saying it takes bad. I disagree it doesn’t taste bad at all.

I've been using this for a while now, together with Kick-Ass Allergy and Tree Country because I have allergies and sinus issues all year long.

I have been using this product for some time. It works amazingly well. I try to keep it in the house at all times for sinus problems.

Kick Ass sinus and immune are helpful and more affordable. Thanks.

Start as soon as possible and always get good results.

Kick-Ass Sinus always relieves any sinus troubles I may have with allergies that lead to infection. I rely on it, and find it the most effective resource I have. Thanks.
