The only thing that made a difference

Post meniscus knee surgery, my wife was still suffering from knee pain for over a year with very little helping to ease that pain. It turns out she had some scarring issues and even with physical therapy exercises it was still painful for her. After looking at this online and researching it, I finally bought it for her and within a few months she was pretty much back to her old self. For my wife who is on her feet and walking all day long, this was and continues to be a lifesaver.

This product does work as inteneded

I have been using Flexagain for 6 months now and it has been very effective at keeping my Osteoarthritis in my knees "at bay." I do get occasional "flare ups," but nothing that keeps me in intense pain. My goal is to not have to have knee surgery or at least delay it for as long as possible, especially since I am an active person. With the combination of shots to the knees and Flexagain, it has worked extremely well and keeps me happy. If you do research, Flexagain seems to be the only joint supplement that has all the needed ingredients to keep the inflammation down, which is what we battle as we get older.

I got FlexAgain for my dad

I got FlexAgain for my dad, after a month of conviction him to take it, he finally did. And the results are really good. He's tried other things and he's generally quite grumpy about this sort of thing. So the fact that he takes it and it's working is really all I can say. Top product.

I bought this product for my grandma 2…

I bought this product for my grandma 2 months ago and she says it's made a huge difference and it shows. She has severe problems with her knees and since she's been taking it not only is she way more active, but she's taking less pain relief. She's tried a lot of different stuff over the years and says this is the first one that's really made a noticeable difference.

And I don't normally leave product reviews, but their customer service was fantastic. USPS left the package on our porch even though we do ask them not to as a lot of packages get stolen from our area. Anyway, you can guess what happened. We asked FlexAgain if they could help, but expected to have to just buy another bottle. But, they immediately sent out a fresh bottle no questions asked. Now, it's important because that is at their expense. USPS will say it was delivered properly so it's not like they'll see anything back.

They're just a really nice company to deal with and their product is great.

Relief For A Retired Wrestler

As a retired professional wrestler, my body has gone through a lot over the years and not a day goes by that I don't wake up in pain.
I've tried various supplements through the years and found most of them to be nothing more than a placebo.
However, with FlexAgain, I was pleasantly surprised to have a different experience.
While no supplement is ever going to make me feel like I used to, it has given me back the mobility in my joints and relieved the daily pain that I was experiencing, to allow me to enjoy the rest of my life after wrestling.
