Testimonials What Customer Say About Guai-Aid...

amazon

Yay! They don't choke me!

I love that these are so small compared to others. I have not had one stick in my throat at all, and that's SO important because I have to take them 2 - 3 times a day. Thank you Guai-Aid!

Smaller than most Guaifenesin tablets

It works as well as other formulations of Guaifenesin, but it’s smaller than most of the tablets you can buy. I needed the smallest I could find because the patient can’t swallow well.

Capsules a Plus!

Wanted a Mucinex supplement that was not a tablet or caplet. I have a hard time swallowing those. This was perfect. Easy to swallow, the right dose and 200 capsules at a great price.

No more dizziness!

My doctor recommended guaifenesin because I complained of dizziness when turning my head. They've solved my inner ear congestion problem & now the merry-go-round feeling is gone. If you have trouble swallowing, these will make that job so much easier. The photo shows the difference between this brand & the Costco "big blue" version.

Fast delivery, great product

I have used Guai-Aid 600 mg caplets for several years. Thank you for a great product.

High quality product!

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!

Not as effective as Mucinex

My review is based strictly on my perceptions of the effectiveness compared to Mucinex. I took Mucinex daily for several years and decided to try this product to save money. This does not clear my lungs as Mucinex did. I'm going to have to go to 4 per day and see if that improves.

The same supplement, different brand

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.

Not easy to swallow for me

I found these not easy to swallow. I have a small throat and it was hard for me to get down. I will go back to liquid or pills I can cut in half.

Helps with sticky phlegm in throat

I take this in the early am to relieve sinus/reflux problems it helps to loosen the phlegm so you can blow your nose or otherwise expell it, ideally. This is a good company/product. I was getting this for years straight from them so I was glad to see I could get it from Amazon now. I like that there are no questionable fillers or other medicines for other symptoms I don't have. Just the guaifenesin.

Very effective in managing congestion due to sinus condition.

I like the ease of swallowing; the previous Guaifenisen I took was a large pill without the slick covering this capsule has. The old one often stuck in my throat, causing a lot of discomfort. This one is easy to swallow, and does the trick.

Easy to swallow capsules

I love this product. It’s so easy to swallow. I ordered caplet by mistake. The company called me from CA and fedexed new capsules to me. Very impressive. It’s not often today that you receive such outstanding service.

Active ingredient in Mucinex, which is quite expensive. This is very cost-effective!

Great product = Great Company

I have been using Guai-Aid brand of guaifenesin from Health Products Express for almost 20 years. I have ordered directly from Health Products Express and, for convenience, through Amazon, Service has always been excellent and the product really works.

Love your health? Then this is worth the read.

I am 64 yrs old and used this product for about 2 months for excessive phlegm. Mucinex are so expensive. I have COPD & asthma and need help with phlegm EVERYDAY. For 2 months - I thought or wanted to believe I was getting help from the Guai-Aid 600mg (I take 2 to get1200mg). I noticed my cough to clear phlegm was just not improving, getting to be too much. I decided to try Mucinex-Max Strength 1200mg for a week AGAIN. Just as expected- everything improved including my ease of breathing. I really wanted to be able to save some money with a less expensive product but I can't do it at the risk of my health I bought a 42 pack of Mucinex here on Amazon for a decent price. If you buy through subscription you can save even more $. I honestly believe this is the first time I've had to write a negative review. I have trashed my bottles of Guai-Aid 600mg- I write this because I don't want you to experience the same thing. May the force be with you!🙂

Not easy to swallowing.

These are “tablets” with no real coating for easy swallowing. I have trouble with them getting stuck in my throat.

Very important medication for folks with impaired Neurology

I have 1) Peripheral Neuropathy and 2) weakened swallow reflexes due to a dissected carotid artery. These cause phlegm to build up on my vocal chords. Guaifenesin helps loosen phlegm and reduce speech problems.

Better than waiting and having to use albuterol

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.

Guai-Aid® 600mg"Utra-Pure" Guaifenesin Caplets

I use this because have COPD and one of the effects is a build up of phlegm in my throat. I have used Mucinex in the past and switched to this as a much less expensive alternative. This really does the job!

August 16, 2020

Great value for this Mucinex generic.

I can't afford the cost of Musinex and I need to take it constantly to avoid illness/infection. I can get 100 tablets for a few dollars more instead of only 2 weeks worth for $14.00+ taxes. I just have to reorder a week or so ahead of time before I run out. Awesome deal.

They work very well and are much cheaper then OTC Mucsinex.

You do need a lot of water to get them down, but, it's worth it. They work well.
