Tried and true!
I've been using this for over 4 years now and this has to be the best thing I've even done for my dog! He's an 80# lab about to be 10 years old and he's not slowing down! He has 0 hip issues and plays fetch all day every day. I started this when he was 6 in hopes I could delay arthritis or hip issues that larger dogs are prone to. I didn't want him to have to be on prescriptions like pain meds so I started him on this early and it's totally worked! He is so so active and I really believe it's attributed to the glycoflex 3! He's a lab so he eats anything but he has no problem with the large chewable tablets. He doesn't even chew it, just gobbles it up. The maintenance dose at 80 lbs is 1 tablet a day so this is such a budget friendly option. I even prefer the ingredients in the glycoflex over cosequin and this is a better deal. I'm always researching what supplements I can give my dog to prolong his health and this ticked all the boxes. After 4 years of ordering this I've never gotten an expired or nasty batch. It's always been really a consistent quality product. I've found this glycoflex3 tab, along with the Ready Pet Go brand turmeric and collagen chew, plus Pet Honesty brand Omega 3 fish oil is the perfect trio for joint health. I started the turmeric chews and fish oil 2 years ago and they've been great affordable additions to the glycoflex 3. I'll keep my dog on these as long as he keeps tolerating them! He doesn't have any upset tummy with any of these supplements :) highly recommend!!

Made a Huge Difference for Our Senior Pup’s Mobility!
We started our senior Golden on GlycoFlex 3 a few months ago after noticing stiffness and joint pain slowing her down. The change has been incredible. She’s moving with more ease, getting up faster, and even has more energy to go on walks again. It feels like she’s gotten a second wind in her senior years. The chews are easy to give—she loves them like a treat, so no struggle at all. I’m so grateful for the difference this supplement has made in her quality of life. Highly recommend to anyone with an older dog dealing with joint issues.

My 10 year old lab is CHASING BALLS AGAIN!!!
I bought this product 6 months ago because it had Green Lipid Mussle, recommended by the American Kennel Club. This product had all of the ingredients of a more expensive product that I was using, plus some. My 10 year old lab had started to decline, and was not interested in running the catch the ball, her eyes were getting milkier and she was generally just not really interested in moving around as much. After some research, I landed on this product. IT's MADE A MASSIVE DIFFERENCE and I share it with all of my friends. Not only is it under $40 for a 4 month supply (65 lb dog - so if your dog only needs half, its a 8 month supply), we noticed major improvements in our old girl. After just ONE week on this supplement, we noticed an increase in energy. A few weeks later, she was barking for us to throw the ball again, and 6 months later we are getting SHOCKED expressions when we say she is 10 years old. She is full of energy again, running around with her 5 year old sister, wrestling her sister again, chasing balls, going for walks without dragging behind and over all looks SO much better. We still have her use her stairs to get into bed, since we have a very high bed, but the improvement we have seen in her has been incredible. The only thing we changed was her SUPPLEMENT so my vet believes it's been a huge help for our aging senior dog with hip and joint pain. We've even started giving our 5 year old dog a half a supplement just to get a head start on helping out her joints and healing. If you are debating trying this, I highly recommend giving it a go. This has been a NOTCICABLE game changer for our girl!!

Glocoflex 3 Magic!
We have several large dogs. We also live on a steep hill which is wet from rain most of the winter. One of our girls has Grade 2 elbow displasia. Glycoflex 3 is part of the protocol we use to keep her comfortable, playful, and wildly happy to be alive at 8 years old. GLM is a great source of manganese which increases ligament strength. As our hill has a tendency to destroy cranial cruciate ligaments and the ligaments in the feet, we have found G3 to be a great strengthening element for all our dogs' ligaments and overall health. None of my girls really love the taste, but I smash up the wafers, mix them to my dogs' breakfasts, and they never notice. We have relied on the Glycoflex products for over a decade!

Glycoflex: The Vet-Approved Pep Pill for Pooches!
When my vet recommended Glycoflex 3 as the go-to supplement for my French Bulldog and senior blind Dachshund, I knew it was worth a shot. Fast forward, and it's clear this wasn't just a suggestion - it was a game-changer, earning a hearty 5-star approval from a grateful pet parent. As someone who's far from a vet, I rely heavily on professional advice when it comes to my pets' health. Glycoflex's 30-year reputation among veterinarians is reassuring. It's not just a random pick; it's a tried-and-true formula that's clinically proven to boost hind leg strength in just a month. Each tablet is a powerhouse, equivalent to two soft chews but much easier on the belly - perfect for my sensitive pups. They're even chicken-flavored, which means no nose-turning at pill time. It's impressive how it combines joint-supporting ingredients like glucosamine and MSM to cushion and strengthen those precious puppy joints. Using Glycoflex as a preventative step, based on my vet's sole recommendation, gives me hope for many more years of frolic and fun with my furry friends. For any pet owner looking for a trusted joint supplement, Glycoflex, backed by veterinary science, could be your best bet.

GlycoFlex 3 helped restore pep to our dog's step!
This is a repeat purchase of GlycoFlex. Last summer we adopted a middle-aged Dutch Shepherd (7+ years). She was favoring her hind leg intermittently, especially after play, so we took her to the vet because we thought she may have pulled something. We ended up getting an x-ray that showed some severe deterioration and displaysia in her right hip. The vet prescribed an anti-inflammatory, but our girl got sick and we started looking for a natural remedy. We thought we'd give GlycoFlex a try. After about 4 - 6 weeks our girl was experiencing only minimal pain when getting up after being down for an extended period. She also stopped favoring her hind leg when walking and playing. Now -- almost a year later -- she bounds up and down the stairs, is playful, walks daily, and only very rarely favors her leg. We also give her a daily dose of salmon oil. If you are looking for a natural anti-inflammatory, GlycoFlex with a dose of salmon oil is the ticket. The other great thing about GlycoFlex is the dosing - when you read the label on other products a normal dose is often 3 or 4 chews/tabs per day. With GlycoFlex, the initial dose (first 4 weeks) for our 52 lb. dog was one tab. The maintenance dose is now 1/2 tab per day. Given there are 120 tabs per bottle, this ends up being a very cost effective supplement. GlycoFlex 3 is the highest level for older dogs. I'd recommend getting GlycoFlex 1 or 2 to maintain joint health of your younger dogs!
