Sinus support

I will not be without this Sinus Support supplement. They clear my head and I give them to my animals too.


I find it very helpful in relieving the congestion of a sinus day, and days when sneezing and irritation develop it calms it. I think it is a great product and very helpful.

I have been taking this product for quite a while now. I used to get sinus infections so bad I would require antibiotics. I was getting them often. I still get them occasionally but they go away on their own. Since taking these probiotics I have not had to take a antibiotic to get rid of a sinus infection. I also take the multi probiotic that I believe helps as well.
