    Grand Flex + HA Capsules is rated 4.8148 out of 5 by 27.
    Rated 5 out of 5 by from Worth the Buy I've really noticed a difference in my body with these pills. I normally wake up every morning with a numb right arm, and my joints pop on my way up and down the stairs! This product has made my achy body less achy, and I definitely have a greater range of motion. I would highly recommend this product to anyone who cleans stalls for a living! But do as they say, and don't give up on the product unless you're 2-3 months in and still don't see a result. The glucosamine and H-A have better effects over time, and that is what you see with this product!

    Rated 5 out of 5 by from Great combo that really works! At 39, I was diagnosed with moderate arthritis in my hands and feet. Now that I'm 46, I've already tried a few popular joint supplement regimens, but Grand Flex +HA seems to have the right levels of ingredients that really work at keeping the pain and swelling away without having to take anything else for it. Aside from my hands and feet, this really helps me ride more often by what it does for my knees, hips and spine. Between this supplement and my ThinLine saddle pad, there's never a "bad day." Additionally, because of the effects from this product that I've experienced for myself, I'm loyal to the Grand Meadows brand of joint supplements for my horses (jumpers) and dogs as well.

    Rated 5 out of 5 by from Great product! I have only been using this for a few weeks and didn't expect to see results so quickly. However, I have noticed that my knee/hip ALWAYS hurts more if I forget to take it for a day.

    Rated 5 out of 5 by from Great for any one After having 3 knee surgeries I figured having some supplement support is needed. I feed my horse this so if I'm willing to trust it with him I figured why not me. I have been on it for almost 3 weeks and have seen my pain lower and better movement. Don't take anything believing it will be a cure but I can tell that I can bend it better and ride longer.

    Rated 3 out of 5 by from my horse is on it I figured since I won't let my horse go a day with out his joint supps, it can probably help me too! My knees have been feeling better but I dont think I've taken it long enough to see a difference yet.

    Rated 5 out of 5 by from can't live without Approx 4 years ago I began to experience pain and stiffness in multiple areas of my body. I was an active rider/trainer, and could barely get out of bed in the morning. I began extensive testing for Lymes, RA, ect ect. Nothing. I began to try different joint supplements...and settled on Grand Flex. I have taken it now for 4 years. If I run out, and am waiting for replacemets, within 2 days or so...I begin to get stiff, ect. This has been a God send for me...as I continue to teach and ride; pain free. And to work with Smartpak, is always pain free!And I am always recommending this product...even to strangers!

    Rated 5 out of 5 by from Great Product I absolutely love that these are capsules and not the big hunky chalky tablets. They contain all of the ingredients that I would take separately to get the same result. It is also hard to find HA in the larger mg size. I feel they are a very good value for the price as I would not be able to duplicate the ingredients individually for the same price.

    Rated 5 out of 5 by from improves range of motion and pain This product is the fastest acting in it's category. Within three days you can see improved flexibilty and reduction in pain. I am a licensed herbalist and recomend this product to my patients. I use it myself.

    Rated 4 out of 5 by from Worth a try! In January I had knee surgery for a torn miniscus and arthritis. Though I have been taking a joint supplement for the last few yrs., I was wondering if a product with HA might be more effective. So I have been taking this product for about 5 weeks now. My knee seemed to feel better the first week, so I plan to continue and see what happens. I am only on my 3rd week of physical therapy/rehab and the doc also cleared me to ride "if I take it easy", which I am. Am still limping, but feel I'm making progress day by day. Again, whether it's a placebo effect or not, who cares, this product does seem to have positive effects thus far. So I'd recommend giving it a fair try.

    Rated 5 out of 5 by from GrandFlex for Grown-ups This is the first and only glucosamine product I could tolerate because of my shellfish allergies. Besides the joint health, the HA will improve my skin--a bonus! Have noticed marginal improvement in my aching knee but I've only taken the product for 30 days. I know it will continue improving because I've already noticed less pain. I definitely have been telling all my friends about this great product!

    Rated 5 out of 5 by from Works well! I have a lot of joint pain, possibly rheumatoid arthritis, and it's extremely painful when I don't take anything. I figured I might try this, thinking it's going to be better than nothing if it works. Well, I was impressed! It definitely made a noticeable difference after even a week of taking it consistently, though I do notice that on the days that I forget to take it, I am sore, if I forget for several days in a row. Placebo affect? Well, maybe, but hey when I take it I do feel better and things are not nearly as painful. It definitely works.Warning though, these pills STINK. I have to set them out the night before to "air out" otherwise I gag and can't swallow them. They smell like moldy cheese and crackers, YUCK! That's my only complaint. but if you let them sit out on a napkin the night before, they don't stink in the morning.

    Rated 5 out of 5 by from Works Well I have to say this is not the first product of this kind that I have tried however it is the First product that works and no side effects. The product digensts well and I can feel my joints are responding.

    Rated 5 out of 5 by from Really helps your joints I have two bad knees and a bad ankle. When I take Grand Flex rider everyday for the prescribed dosage of 3 pills per day (1 AM and 2 PM), my joints don't bother me. When I go off of it, within 3 days my joints are bothering me again. It cannot be a coincidence. Also, my elderly mother started using it and she also feels less pain and a lot more flexibility in her joints. We LUV it.

    Rated 5 out of 5 by from Still on the 1st bottle i have been taking this product for about 4 weeks and my chronic shoulder pain is much better, not gone but much better. i have no more knee pain.

    Rated 5 out of 5 by from Definite Improvement I have a mild overuse injury from running, so I tried Grand Flex + HA to see if it would help control the inflammation. After a month, I have felt definite improvement. I have less pain when running, fewer "flare-ups" afterward and significant increase in range of motion without pain, especially when doing a squat or standing up from a low chair. I was pleasantly surprised that noticeable results came within only two weeks. The pills have no taste, but they are a little big.

    Rated 5 out of 5 by from Grand is Great! I flared up an old knee injury and the quickest thing I could find was Grand Flex + HA. After taking the easy-to-swallow capsules for a few days, I read the label and was quite pleased with what I saw: the standard glucosamine, chondroitin sulfate and HA, but also collagen, MSM and cofactors to make sure all the ingredients worked right. Best of all, there is no sugar, fillers, or artificial colors/flavors in this product. I have peace of mind knowing I'm helping my joints with a high-quality, natural product.

    Rated 5 out of 5 by from Really Works! I was having a lot of stiffness and pain in my shoulders, elbows and in one thumb (that one's strange, I know). After a couple of visits to the chiropractor didn't solve my problems, I decided it was time to find a joint supplement. I am amazed at the results that Grand Flex +HA has produced- I am now pain free!

    Rated 5 out of 5 by from My back no longer hurts!! I threw out my back lifting portable tables while helping at an event last year. After going to countless doctors and being in extreme pain that kept me out of work for weeks at a time, I decided to try a supplement. I've tried five different ones that all were recommended by my doctors, but they just didn't seem to work and worst of all would make me sick! Finally I found this one in your catalog. Both my dogs and horse have been on Grand Meadows products for joints and have seen good results. After being on it for only 3 days, I've noticed a difference in my back and I feel pain free! It is amazing!!!!
