At 56, this is the only product that keeps me in the saddle 10-18 miles -try it !!

Less than three days after taking Syn-flex the severe pain in my knees was gone. I'm now able to walk at the mall, go up and down ladders and after playing with my grandchildren, I am able to get up from the floor without any help. I no longer have to live in pain.

I purchased the Original Syn-Flex for 2 of our dogs. After just three doses, the results are amazing. Our 14-year-old Siberian Husky had wobbly legs and at times couldn't get up. We have already seen marked improvement....more energy, and no more shaking legs. My 5 year-old poodle has always struggled with a weak back leg. She is already more energetic and is not babying that back leg. I'm so glad we found your web site! Thanks for such a great product.

AMAZING Synflex Review!
November 4, 2013

I felt I just had to share a bit of my story too- its about myself and my big Newfoundland. 10 years ago I broke both my knees in a scuba diving accident, working as a commercial diver. I had hyper extended them, being knocked over forward with my legs blocked by rocks from the knee down.. I have been on crutches since that time. Celebrex was prescribed, the result was damage to my heart, from having an allergic reaction to it.

Seems like life was out to slap me down, when suddenly my Nephew and his wife were killed leaving 3 children orphaned. My husband and I took them in, even though we were in our 50s, the youngest was 1 year old.. Life had thrown us a HUGE curve. My biggest concern was with the little ones in my life, how could I begin to keep up with them with 2 messed up knees? Until I heard of Synflex, I was scared of trying ANYTHING after the horrific time on Celebrex... I never feared the future so much....

With my husband’s encouragement, I started the program. In 3 weeks I was walking without crutches, the first time in 5 years. Now I won’t mince around, there was still pain- but NOTHING like what it had been previously- I was able to function almost normally.

Then disaster struck again, our big Newfoundland girl broke a ramp climbing into a truck and fell 15 feet, tearing both her knees apart... Surgery and plates later, she was able to walk but it was painful for her in every way.. Until I started her on Synflex.. in a month, after we started, she was our bionic dog, trying to jump tall buildings in a single bound! ha ha.

This was 5 years ago. Today I have had both knees replaced and still on synflex and was out of the hospital in 4 days and home in that week.. The doctors are amazed at my recovery, and I have FULL flex and extension on both legs- My dog, Taz is 11 years old and still going strong, with her bionic knees as well. Her Vet appointment last week was amazing as he said she has the health of a 8 year old newf. I look forward to the future so much!

Thank you my friends, for your continued sales and support. Getting mail to Dutch Harbor, Alaska is difficult, but YOUR product comes through the US mail and I get it within the week of order.
Your friends,
Jeanne and Tazzila the Newf.

I have been using Syn-flex now for a couple of years.

My male German Shepherd has left hip dysplasia.  Using the Syn-flex, has made a drastic improvement in his left rear leg.  He now can run and play without having to lie down every few minutes.  He is 4 years old and plays like he is still a puppy.

Also, I have a female German Shepherd who will be 7 years old in February of this year.  She has recently been diagnosed with Spondylosis (bone spurs growing on the spine).  She has been on the Syn-flex for 3 weeks now, and this product has given her a new life.   Prior to the Synflex, she could barely walk or hold her head up.  Her body was in so much stress, that she had the runs so many times.  Now I can totally say, that she runs again after her balls and totally enjoys her outings again.
Great product! I use the Syn-flex original for pets.

Synflex is a leader in the marketplace for effective arthritis and joint care products. All of Syn-flex liquid glucosamine formulas are made from premium quality ingredients.

Syn-flex begins it's formulation with pharmaceutical grade liquid Glucosamine Sulfate and Glucosamine HCL. But they do not stop there. They add 10 other beneficial ingredients that:
-Ease joint pain.
-Assists in rebuilding damaged cartilage.
-Reduces inflammation and,
-Improves mobility.

Synflex Ingredients list here.

Synflex®, with its innovative liquid formula, has proven itself to be an effective product for those suffering from osteoarthritis and cartilage degeneration. This cartilage breakdown eventually causes bone on bone contact. This is what causes the joint pain you’re feeling.  Glucosamine products today are still mostly in the form of pills. While they can be effective, the time for pills to produce results can take from 6 to 8 weeks or longer.  Synflex, with its liquid formula, has shown to be effective in many of those taking it in as little as one to 2 weeks. The reason for this is absorption. Liquids absorb into the bloodstream much more effectively than pills. This high rate of absorption means your body is getting more of what it needs faster, to begin working on the joints affected by osteoarthritis.

Syn-flex® is just as effective in pets too. Cats, dogs, horses, even pot belly pigs have just as many joint problems as people, and Synflex works exactly the same way in easing their joint pain.  Syn-flex® for Pets is dosed by weight and its biggest advantage is the ease in which you administer it. Pour a little in their bowl or on their food once a day and you’re done.

 Athletes also benefit from Syn-flex®.  The workouts athletes put their joints through take their toll. Synflex can ease the damage done and assist keeping their joints in top shape and maximize their time spent preparing for competition.

As mentioned, Synflex uses Glucosamine Chondroitin liquid for joint pain, along with ten other ingredients (boswellin, bromelain, yucca, omega 3 and omega 6 fatty acids, and white willow bark just to name a few) that work synergistically to make  Original Syn-flex and Syn-flex 1500 products one the most effective arthritis formulas available today.  Check out the complete list of beneficial ingredients in Synflex and Synflex 1500 brands here.

Over the years, many studies have been done to prove or disprove the efficacy of glucosamine. The results of these studies have varied but the most recent study conducted in the United States has concluded that glucosamine, especially when paired with chondroitin, is very beneficial in the treatment of osteoarthritis, reducing moderate to severe pain more effectively than celecoxib (Celebrex)which was also part of the study. Syn-flex formulas provide these ingredients along with others to finally offer relief to those suffering from osteoarthritis and joint pain.

And I want to mention again, it usually takes between six to ten weeks to notice any results when you take capsule/pill form glucosamine products. Syn-flex® can deliver the pain relief you're looking for in as little as 7 to 10 days as reported by many of our customers.

Factor in cost and the once a day dosing of Synflex, and it's a simple choice for a product with a long history of success.

Even in severe and advanced cases of osteoarthritis, the vast majority of our customers report significant improvement within 3 to 4 weeks. Even better, Syn-flex® carries no serious side effects. Cox-II inhibitors like Vioxx and Celebrex, come with a long list of dangerous side effects.

Syn-flex® contains the highest possible quality liquid glucosamine sulfate and HCL, cartilage containing 20% chondroitin sulfate, boswellin, yucca powder, manganese ascorbate, bromelain, vitamin C, omega 3 and omega 6 essential fatty acids, vitamin E, and vitamin A. You can find out what these ingredients do at our "About Synflex" page. All Syn-flex® formulas are guaranteed to reduce your pain and ease your osteoarthritis symptoms, or you get 100% of your purchase price back. No questions asked.

>SYN-FLEX uses all natural ingredients that promote healthy joints. By reducing inflammation caused by arthritis, pain is reduced or eliminated aiding in mobility.

also relieves the stiffness associated with arthritic joints. This also minimizes pain and improves mobility. The ingredients GLUCOSAMINE SULFATE/HCL AND CHONDROITIN SULFATE are natural substances in the body that functions with other substances to promote healthy muscles. When the joints begin to deteriorate due to ‘wear and tear’ or else by reason of unhealthy living, arthritis often sets in and pain begins to target the spine, elbows, knees, hip, and other areas of the body. Some believe that arthritis only targets the knees, elbows, hip and spine, however arthritis pain will cause suffering in the shoulder area, as well as other areas over the body. Both humans and pets suffer arthritis each year. Glucosamine is a scientifically studied neutriceutical that has helped thousands worldwide cope with arthritic pain, helping to restore the bodies GLUCOSAMINE AND CHONDROITIN SULFATE levels. SYN-FLEX Liquid Glucosamine

MORE SUCCESS..Syn-flex for Dogs

I have a 2 year old GSD (German Shepard) that at a very early age started having joint problems. Well of course the vets want you to use all kinds of anti inflammatory drugs and steroids but I have a huge problem with the side effects of long term use and how it can actually shorten your dogs life. This is a young dog and I want her around for a long time so I did some research and found your product. I did not order it from you at first I did order it at a different site but a friend of mine directed me to you. I have to say this dog has made a great improvement in just a few weeks. She still limps a bit but her energy levels, and overall health seems to have improved greatly. She is eating better, and I can tell she is no longer suffering in pain. I can deal with her limp as long as I know that she is not hurting, and if you would see her run around with my other two dogs, you can tell NO PAIN LOL. I have recommended this product to many people at my Kennel Club because with GSD's being prone to HD and with surgery not always a solution, I think the benefits of this product will improve quality of life for these dogs without extreme invasive tactics.
Thank You,

For people, pets, and athletes, Synflex has a formula to deliver healthier, pain free joints.

  • Each 8 oz. Bottle of Syn-flex and Syn-flex 1500 Contains 32 Adult Doses, a FULL Months Supply! Synflex for Pets can last 4 times as long because dosage for pets is based on their weight. Check out the Synflex for Pets weight chart here for proper dosing of liquid glucosamine for your pet.

  • Once a day dosing makes Syn-flex an easy way to treat arthritis joint pain. You can drink it straight, or mix it. I prefer taking my Synflex 1500 with my evening meal. I just add it to a couple ounces of what I'm drinking. Just squeeze the bottle and the built-in side tube will fill the pre-marked reservoir to the desired dosage. For pets, adding it to their food is much easier than dealing with pills. Because pets take a smaller dose, it may be easier to pour the correct amount into a teaspoon or tablespoon depending on how much Synflex you need.

  • Original Synflex Liquid Glucosamine is Apple Flavored, Synflex 1500 is Orange Flavored, and Synflex for Pets is Beef Flavored. Bottles have a Built-in Measuring device for easy, accurate dosing for you or your pet. If you're starting Glucosamine therapy, results have been seen in many in as little as 7 to 10 days. Wiith a low cost of under 80 cents a day, Synflex is a real bargain, and a very safe, effective alternative to prescription drugs.

Looking for a product designed to give your dog or cat joint pain relief? Synflex for Pets is one of if not the best liquid glucosamine chondroitin products available today.

As a treatment for arthritis or other joint problems pets endure, Synflex is a perfect choice. Joint care for dogs and cats has never been easier. Just add the minimum dose required for your pet to their food daily and you're done.

Liquid glucosamine for dogs, cats, and all other pets, delivers an easy to administer solution for pets suffering from joint ailments brought on from arthritis and old age. The success of this product for dogs, cats, horses, (we even have a pot belly pig as a customer) has been remarkable. Instead of masking pain with dangerous drugs in pill form (and we all know how much fun it is to get a pill down your pet), Synflex for dogs actually helps to regenerate the joint to eliminate pain. Just read the reviews from those pet lovers that give it to theirs. Pets don't lie. If a pet, limping and struggling to get around, is put on Synflex, within a couple of weeks you'll notice a marked improvement on his/her mobility. More mobility means less pain. There is no placebo effect with pets. Our customers rave about its success on their pets and you will too. Dosage is according to your pets weight with most pets using 1/8 oz a day. This safe and effective dose has a bottle of Synflex Liquid Glucosamine lasting a full 2 months, only pennies a day. You'll save that alone in cheese and hotdog's we all use to give our pet pills (which somehow, they still manage to eat the treat and spit the pill out on the floor.

The following e-mail sums up the dramatic results people are seeing in their pets.

Synflex for Pets Reviews

  I've been giving Syn-Flex to one of my Golden Retrievers for about a year, and if I hadn't had someone telling me about the product I was almost going to have to have her put to sleep because of her joint problems.  She really suffered...but after two weeks of being on Syn-Flex she's doing very well...she's actually running which is something she had not done for a long time. 
Thank you!  If I knew who came up with this formula I'd thank them as well!

Hi Rob,
What a great story! I have a dog on Synflex also and it really does make a difference. I always love hearing success stories, especially with dogs.
Thanks, Diana

Thank you for writing!  And really has been a success with Syn-Flex. to the point when she went outside with me to do her job...she would get so tired she'd sit after only walking about fifteen feet...then I'd have to wrap her leash around her waist and pick her hind quarter up so she could walk back to the front porch and up the two steps into the house.  It was really sad to see this dog who was only five years old to deteriorate as quickly as she did.  Accidentally, I bumped into a couple while I was walking my other two Golden's and they told me about the Syn-Flex and how it helped their aging St. Bernard...and his mother.  So I believed it, ordered it, and two to three weeks later there was a major change and it's been getting better and better ever since!  Sorry I'm going on and on but I can't thank you enough for selling this...I've got my "puppy" back again and hopefully for a long long time.

Thanks again for answering my first note...
Rob M.

Please note: Pets should not be given White Willow Bark that is in the Syn-flex 1500. Please use Original Synflex or the new Beef Flavored Synflex for Pets if you are purchasing for your Pet.


My son gave me the information about SynFlex and I decided to try it on our year old boxer who has just recently been diagnosed with debilitating arthritis of both back knees.  She has had to have surgery on the left knee and will soon go in for surgery on the right to give her better stabilization and slow down the crippling process.  Even with the surgery, Sammee would cry out when ever she stood up or attempted to lie down.  Within 2 weeks of her taking SynFlex, there has been a remarkable change in her level of pain tolerance.  She no longer seems to be in pain with either standing or lying down.  She had been to the point that she was not putting weight on her left leg but that has now changed.  Although she is still stiff due to the disease that she has, Sammee is a lot more active and is able to once more run without the pain she has had for so long.
Thank you for making this product available to pets.  Nothing else we have tried has worked as well as this does.

and another Testimonial....

I ordered Syn-flex as a last resort of my 10 year old beagle basset, it has worked wonders. Also my 82 year old mother who has painful arthritis loves it!! I'm telling everyone I see, especially at the vet.

Amazing Results.....

I received my order last Saturday and my dog, Mouse, a 7 year old Japanese Chin, is very finicky. For the last two months, she has not been herself. She has been much quieter and not as loving. One day when I reached down to pet her, she cried out as if she was in pain. The vet suggested I try giving her a pain pill and she acted much better. I did not want to keep her on that type of medication as there are too many side effects and it is only masking the problem. I tried giving her Glycoflex pills, but she refused them even when disguised in food. So I decided to look for a liquid form. I was surprised to find that the liquid is better absorbed and when I found your product, I ordered it right away. It arrived quicker than expected and I gave Mouse her first dose Saturday afternoon. Starting Sunday  I gave her a dose in the morning and and at night, after I fed her. She LOVES it and looks forward to taking it, but best of all she is almost her old self. She is again getting on the furniture and spinning around  before she goes out the door. This little dog is very,very special, she was born here on the morning of 9/11. I gave her to my best friend, who spoiled her to death. When she died four years ago, Mouse came back to me. I am so happy and have been telling everyone about the Synflex and your fast shipping. THANK YOU!!!

Synflex Pet Reviews

Synflex Works!.....
This is absolutely the best product I have ever used. I am 47 years old and have had problems with my joints for the past 3 years and have tried lot's of things to help with no success. I went to the doctor about 2 months ago and he wanted to give me cortisone shots in my knee's, hips, and my neck, which is where I have the most problems but I knew that this wasn't the answer so I left without them. I had been waking up in the mornings like someone had pumped me full of glue and took me a little bit to loosen up. Just 3 days after taking Syn-flex, I felt great in the mornings with no more stiffness and after about 15 days, my knees, hips, and neck were much better and after just the one bottle, I have very little joint pain at all and feel that with continued use, it will all go away. It had gotten to where my knee's would try to give out on me going up step's and felt like something was under my knee cap trying to pop it off but now, I go up and down steps like a 19 year old with very little pain. Thank you so much for this product, it has been a "Life Saver"!!! God Bless...
