Love this

04/07/2026

As someone who has an older dog, I’m always looking for a product that can help her. I love that this target older pets has great ingredients. I’ve definitely noticed when my dog gets up. She has a smoother transition now where before you could tell that it hurt her.

slight improvement

04/04/2026

I have noticed so far after a few weeks slight improvements — smoother movement, less stiffness getting up, and more willingness to go for a walk. It’s clear this supplement is doing exactly what it promises for joint and mobility support. The tablets are easy to give (my dog actually likes them), and I appreciate that it’s made in the USA with ingredients I can trust. It feels like a true all-in-one multivitamin for older dogs, supporting joints, ligaments, and overall wellness without upsetting their stomach. I also love that it works for all breeds and sizes, which makes it a reliable choice no matter what kind of dog you have. The quality is excellent, and the difference in my dog’s comfort and energy level is undeniable.

Expensive

04/03/2026

At the time of this review, the bottle of tablets retails for $59.95 which is quite expensive. There are a total of 60 tablets in the bottle, so each tablet would be priced at about $1.00. Because of this, my expectations are high. As far as product details, this product is made in the USA. The tablets have a firm crunchy texture. The size of each tablet is pretty small, making it easier to ingest for any size dog. I offered this to my older dog who also happens to be picky and she took it fine since the tablet is small. For my dogs weighing less than 20 lbs, the recommended dose is 2 half tabs a day (or basically 1 a day). My other dog weighs over 50 lbs, so she’ll need 2 of these a day, making this bottle a 1 month supply. This doesn’t work for me financially because I have multiple large dogs. I’ll update this review if and when I notice the effects.

DogtorRx: Keeping Mabel Moving

04/03/2026

Between her pug stubbornness and her boxer athleticism, Mabel puts a lot of wear on her joints. These Age Defense tablets have a firm, chalky texture that she actually doesn’t mind if I crush them into her dinner. They’re a solid multivitamin for a senior-adjacent dog, focusing on ligaments and mobility. Since she started on this regimen, she’s been way more interested in chasing the cats around the living room, which I take as a glowing endorsement of her joint health. It’s a high-quality, Made in the USA supplement that gives me a bit of peace of mind as her “dad.”

Clearly smell good to doggy noses

04/02/2026

I have no easy way of judging the efficacy of these pills, as my dogs haven’t given me much feedback yet. However, they were all eager to try them, so there have the smell right, and they clearly taste good enough for them to come back for more every day. At a dollar a tablet, they can get a little expensive, but if they make them feel more comfortable, they will be worth it.

“The standardized oligopeptide formula is having profound effects on over 66% of the 65+ canine and feline participants in an ongoing clinical study at the Holistic Pet Care clinic, New Jersey. It is especially beneficial in cases of hormone imbalance and neuromuscular deficiency in older dogs. Benefits are also reported in areas of strength, energy, stamina, alertness, disposition and agility. Many with poor appetites are once again enjoying food and gaining healthy weight. I also highly recommend this formula for maintaining and enhancing the quality of life for healthy dogs, as well. It varies, but I have about 45 patients on this formula.”

“I conducted the first study to support the safety and efficacy of standardized oligopeptide formula. The study focused on aging dogs with orthopedic challenges and dogs with suspected or diagnosed Cushing’s disease. Laboratory work, including chemistries, CBC’s, thyroid and cortisol levels, was performed both before and after the administration of standardized oligopeptides. No adverse effects were noted. One participant, an aging Labrador Retriever with significant mobility problems, was taking Rimadyl and Glucosamine prior to the study with little or no results. The owner was considering euthanasia. Within a very short time after adding the formula to his diet, the dog became as mobile as a puppy. Nothing else was added or changed in his treatment. Now, two years later, this same dog is taking only the standardized oligopeptide formula and no more drugs. Remarkable results were also shown on dogs with Cushing’s disease who became active and playful again once put on this regime. Presently, I have about 25 patients taking this formula and the responses are overwhelmingly positive.”

“In my veterinarian practice, I routinely treat dogs suffering from Cushing’s disease, joint-related issues, and from geriatric conditions. I have always been an advocate of preventative health care and the necessity of high-quality nutrition in the daily diet to promote good health and maintain a healthy life. This past year I was introduced to a new dietary supplement for dogs and cats containing standardized oligopeptides, and I now recommend them to all of my canine and feline patients to be incorporated with existing prescribed treatments. I have personally witnessed extremely impressive results within a relatively short period of time on dogs diagnosed with Cushing’s disease, and I have seen favorable results when treating dogs and cats suffering from arthritis, diabetes, hot spots, anxiety issues, hip dysplasia, and liver toxicity. Also, many geriatric dogs have now shown increased energy and mobility and a demonstrable appearance of overall well-being. Recovery time for dogs recuperating from surgeries has also been reduced. I recommend this proprietary formula for dogs and cats of all ages, to be used as a daily tool for
good health maintenance and as supplement to be used along with their existing treatment program.”
