Testimonials What Customer Say About Guai-Aid...

amazon

I've tried many different brands of Guaifenesin/mucus relief over the years. These tablets are smaller than typical 400mg Guaifenesin of other brands AND easier to swallow, all while being less expensive and containing less binder/inactive ingredients than other brands. Best on Amazon hands down!

This is the same supplement I’ve used for a while now to combat my persistent post-nasal drip, and more cost effective than other brands. I don’t like the large lozenges as they are hard to swallow, however.

I have mild allergies, and my doctor recommended that I take this. Seems to help, and the price is low. I plan to buy more as needed.

This is so much cheaper than the name brands and I find it just as effective.

These are the basic brand of Guaifinesin. They were much cheaper than usual stores. Have a small bottle for every day use and the big bottle is stored and refill as needed. The tablet over itself is thin. Some capsules have a fatty taste. These capsules have no taste and very easy to swallow and don't seem to stick to each other when I take two.

I have severe hay fever. I can get most symptoms under control but the low intensity asthma. I hate using albuterol, especially at night when I most need it. Taking this regularly keeps my lungs "moving" throughout the day.

Miss read the description. I thought it was 8 hour. I threw them away.

Since this changed from a prescription drug, this pure version was what I switched to using. Much better value than Mucinex!

Didn't work as well as other brands.

Quality control is unpredictable. Each capsule almost never contains the same amount of medicine found in a Mucinex tablet. Other generic brands (such as Kirkland) can easily be found on Amazon for about the same money.

Guai-aid is the best over-the-counter drug to get rid of sinus congestion without you having to go to the doctor. If you take it for a day the way that it says to take it, you will feel 100% better the next day. It is a little bit pricey, but you do not have to take it past a couple of days, so over the long run you have saved money. It works!

I know it works, because it clears my sinuses as well as and even better than Musinex. Clean, harmless ingredients deliver pure Guaifenesin in gelatin caps. Thank you Guai-Aid for a healthy and fair price Guaifenesin!d

This is a great product, the ingredient that’s effective for congestion without a lot of extras. I use it constantly, with my doctor’s approval, and it makes the difference between a clear head and constant brain fog.

These are the purest for the best price. I take 6 in the morning and 6 at night and my lungs have been clean as a whistle for years!

I've been taking guai for 9 years after being diagnosed by Dr. St. Amand. It changed my life and I have felt fantastic since then. Unfortunately the long acting guai brand carried by the fibropharmacy was discontinued so I had to try this version as I did not want to use mucinex because it contains blue dye. I've been taking for over a month and not only do it not work but it also gives me an upset stomach. This side effect was also in other reviews. Buyer beware, this product is not effective if using for fibro.
