Helps manage my seasonal allergiesby Mom in Oakland on Oct 21, 2018 (Source: Amazon)

I find this supplement helps manage my seasonal allergies, and I like it that there are no side-effects, like there are from pharmaceutical anti-histamines. Great company!*

Perfect alternative for allergy suffers!by mel frausto on Oct 21, 2018 (Source: Amazon)

I took just about every allergy medication out there. Always had to have the decongestants, therefore I was a bit spectacle about trying this. It’s been over a week and I feel great! Highly allergic to ragweed which is in full bloom right now, and I honestly have to say LES Labs Sinus really works! Must try!*

Works greatby Brittany Lipham on Oct 21, 2018 (Source: Amazon)

It’s really helping with my post nasal drip! Love this stuff!*

Works wellby Kellie Kirkpatrick on Oct 19, 2018 (Source: Amazon)

I had been taking a different brand that was a higher dose, and WAY more expensive so I was skeptical that this would work, but it did! Took care of most of my seasonal allergy symptoms!*

Excellent Supplement!by Melissa Williams on Oct 19, 2018 (Source: Amazon)

I tend to have allergies and sinus problems all of the time. I also have a hard time breathing well through the night while sleeping but this supplement has seemed to help keep my histamine levels healthy and keep me breathing freely. It's nice to find an all-natural supplement instead of relying on sinus medications all of the time. This stuff works great and I love that it's all-natural!*

Get rid of my post nasal dripby julie lin on Oct 17, 2018 (Source: Amazon)
