Les Labs Sinus & Seasonal Supplement by Nayda I. Cartagena on Mar 16, 2017 (Source: Amazon)

Great for my Florida seasonal allergies, good product and great price. I will be sure to purchase it again, when my free bottle runs out.*

Works Great on My Allergies by Taylor on Mar 16, 2017 (Source: Amazon)

This product works wonders for seasonal allergies. I have been using this for two years during the months when I normally experience allergies and I have not suffered my usual symptoms. Whereas, my husband who has also experienced similar allergies during the same months and who had not been taking this supplement had continued suffering until he finally decided to take my recommendation on these supplements. He also no longer suffers and he swears by these. My daughter has recently been miserable with allergies and has asked me to send her some.*

like many others by Eugene G. Narducy on Mar 15, 2017 (Source: Amazon)

I have, like many others, suffered with allergic reactions to various things in the air, notably tree pollen in the spring. And, to find relief had to buy the various OTC products both sprays and pills and seen the doctor for the stronger stuff. Last year, I discovered a product containing butterbur and surprisingly got results. I bought this product until it was no longer available and luckily discovered LES/LABS Seasonal Relief.All I can say is this stuff really works. I take a capsule at 6AM, 2PM and 10PM and I am symptom free. There are 4 components in this capsule that includes butterbur. Do your research on the contents and you'll understand why it works so well*
