The worst of it was the fatigue it caused. After taking this one day he still feels some sinus pressure (could be just from the cold) but he doesn’t feel the drain and severity of infection. I don’t believe in miracle drugs, but this might be it. Love seeing the energy he has back. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Worth a try! *by C***E on Reviewed in the United States on September 23, 2020* I had a really bad sinus infection this year as a result of allergies. I took this along with several other supplements. I think it has helped! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/22939672-douglas-laboratories-multi-probiotic-sinus-support-probiotics-and-prebiotics-additional](https://www.desertcart.tn/products/22939672-douglas-laboratories-multi-probiotic-sinus-support-probiotics-and-prebiotics-additional) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-07*
