Thank you for this amazing product!
I have a Kitty who was losing strength in his legs and exhibiting lack of mobility and damage done from a prior steroid pills prescribed by a veterinarian.
Your other products help me get him completely off the steroids but he did have trouble walking and climbing.
He’s been on your Flex-N-Free for about 2 months now and no longer exhibits any pain in his legs when you pet him or brush him. He is climbing and jumping out of bed just like he used to do.
Obviously, this makes him more relaxed, mobile and able to sleep well without pain. Once again you have performed Miracles and we thank you! M. Barto

Recommend it to anyone with an arthritic cat

My senior cat was suffering from arthritis pain in her spine. She would let out an angry growl every time she went to stand up from a lying position, as if to say "Ow! That hurts!" I ordered the Flex-N-Free and was happy to see that she mostly ate it just fine when mixed into beef or turkey flavored wet foods. (Fish flavors, not so much.) After about 2 weeks I noticed a significant difference. At about one month the growling stopped completely and she seems to be moving around easier. I really think it has helped lessen her pain and would recommend it to anyone with an arthritic cat.
After just a week she walks without limping

My cat Mickey, a 9 year old long hair originally feral cat, seriously injured his shoulder while jumping a baby gate that was not locked. He had trouble walking and was clearly in pain. I took him to a vet specialist who took x-rays which showed his shoulder bones were grating on each other from the injury but he also had arthritis as well. Surgery wasn’t guaranteed as a solution and at $3,000 was simply not a possibility for us. I started him on the Flex n’ Free product and give it to him twice a day with meals. He still has a slight limp but is totally back to his very loving personality, running up his tall cat stand and throughout the house. My other cat Maggie is a Maine Coon and at 15 years she has also developed arthritis. She is a constant purr machine and when she stops purring I know she is in pain. I just started her on the Flex n’ Free a week ago. After just a week she walks without limping and is back to her happy purring self! Thanks for developing this very high quality product!
Massive improvement

At the beginning of this year I noticed my generally quite spry 12 year old cat Tigra was hesitating to jump up on my couch/bed/chairs.. anything that was a little high. I read about the Flex n Free and ordered it immediately. After about 2 weeks of giving it to her i noticed massive improvement. It's been nearly a year now and she's just thriving. Thank you!!

Carefully Selected Ingredients:

Arabinogalactan: While Arabinogalactan and its constituent parts are common in nature, the commercial extraction is taken from a Larch tree. It is a water soluble fiber and supports immune competence. Arabinogalactan is a long chain polysaccharides containing arabinose and galactose mono-saccharides. Arabinogalactan is actively fermented by intestinal micro-flora and is effective at increasing beneficial anaerobes such as those in Pet Flora.

Glucosamine HCl a natural compound that is found in healthy cartilage. It is used to help form and repair body tissues and as your animal ages, the natural production of glucosamine in the body slows. It has been shown through many studies to alleviate pain and help rebuild cartilage. Research shows that providing supplements of glucosamine can help restore joint function and activity levels.

Ascorbyl Palmitate (Fat soluble vitamin C) A highly bioavailable, fat-soluble derivative of ascorbic acid. Ascorbyl palmitate possesses all the benefits of vitamin C, but unlike the water-soluble form, is able to be stored in the lipid cell membrane until the body is ready to put it to use. Furthermore, it has histamine lowering properties and increases lymphocyte formation.

Chondroitin Sulfate: Chondroitin is a naturally occurring product found in animal cartilage.In osteoarthritis, the cartilage in the joints breaks down. Taking chondroitin sulfate, one of the building blocks of cartilage, might slow this breakdown.

Lithothamnium (Calcified algae): Calcified red seaweed product, is harvested from the purest waters off the S.W. coast of Ireland. A calcium supplement; absorbs water, and relieves

Bromelain: is a protein-digesting enzyme, sourced from the pineapple fruit. This fascinating compound has traditionally been used as a potent anti-inflammatory and anti-swelling agent. Because it’s an enzyme, bromelain helps the body digest food and absorb nutrients more efficiently, as well as being extremely effective at healing issues in the gastrointestinal tract.

Aloe Vera: (window refractance dried): This is the  leading aloe vera for purity and biological activity, produced by refractance window drying the juice from the inner leaf. The result is the highest biological activity of any drying method. All the immunological activity of fresh aloe is concentrated in Active-Aloe. High heat (pasteurization and/or autoclave methods) break down the constituents in Aloe that are the most valuable for healing.

Serrazimes: Serratiopeptidase, also known as serrapeptidase and serrapeptase, is a protease originally found in the gut of the silkworm. It is produced by the bacteria Serratia marcescens. This protease has been the subject of much research and its use has grown in Asia and Europe. Studies support serratiopeptidase’s benefit in supporting musculoskeletal, cardiovascular and respiratory health.

Vitamin K2 is necessary to convert a critical bone-building protein called osteocalcin. Osteocalcin is a necessary protein that helps maintain calcium homeostasis in bone tissue.  It works with osteoblast cells to build healthy bone tissue.

Argentinean Beef Liver: Fresh from hormone-free Argentinean Beef Liver, from Argentinian natural grass fed cows. These cows have never been on feed lots and freely roam the Pampas. Plus it is a flavor well liked by cats and dogs.


Administer orally 1-2x per day; 1/2 tsp for every 10 lbs of animal
