Just Try Itby Gabi on Sep 15, 2018 (Source: Amazon)

LES Labs is fantastic. This time of year in the Phoenix area my allergies feel like a sinus infection. It happens like clockwork beginning of September. Over the counter allergy medicine has some uppers or something in it making me feel anxious all day. I found this on Amazon because people recommend Butterbur root extract as a natural antihistamine. That is one of the ingredients. It’s all natural. I was not paid to post this haha. I’ve been using it for 48 hrs now 3x a day. I’m hoping to drop down to 1x a day once soon. All of the sinus pressure is gone, the nasal drip and soar throat is gone... I’m still sneezing a bit in the morning but I feel so thankful to found a natural allergy relief remedy that I can take in pill form.*

My allergies are GONE!by D. Cinelli on Sep 14, 2018 (Source: Amazon)

I have had allergies all my life and they make me miserable. I have tried EVERYTHING and nothing really worked. For the first time in my life, no stuffy nose, no runny nose, no sinus headache. I will be re-ordering this for sure.*

Works greatby Rob Gallagher on Sep 14, 2018 (Source: Amazon)

I have tried multiple different over the counter products for my allergies. They may work for a while but then stop. LES Labs Sinus & Seasonal product works better than anything I have tried. I will never be without it.*

Really helps calm my allergy symptoms especially sneezing and runny nose*

Great productby M on Sep 13, 2018 (Source: Amazon)

Allergy sufferer. This product helps me survive peak outdoor allergy season in the spring and fall and minimizes sneezing, itching eyes and scratchy throat. No side effects of drowsiness and dryness that you get with allergy medicine. I take it everyday and don’t notice the change in seasons as much.*

Has changed my life!!by Susan Taggart on Sep 13, 2018 (Source: Amazon)

I bought and started taking the Sinus & Seasonal based on reviews, and I'm SO glad that I did!! I was getting sinus infections about every 2-3 weeks (drainage, sore throat, etc.) for years, and was desperate to find something to help. Since taking this product (once a day religiously) I have not had one sinus infection or been sick!! It's a miracle product, and I will never be without it!*
