What is Doctor’s Best Glucosamine/Chondroitin/MSM with OptiMSM®?
Doctor’s Best Glucosamine/Chondroitin/MSM with OptiMSM® supports joint structure, function and comfort. It is a potent combination of three clinically proven, purified ingredients that help the body manufacture proteoglycans in healthy joints. Proteoglycans contribute to the maintenance of sound joint structure, ultimately enhancing healthy joint function.

Glucosamine sulfate is extracted from chitin, a long-chain polymer consisting of many glucosamine molecules linked together. Chitin forms structural frameworks in many living things, including aquatic crustaceans. Doctor’s Best glucosamine is purified and then sulfated and stabilized with potassium chloride. It is processed to remove residues of protein and impurities, yielding pure glucosamine sulfate as the final material.

Chondroitin sulfate is manufactured from bovine cartilage. Doctor’s Best uses chondroitin sulfate with a purity of 90 percent or greater. Quality assurance testing is performed using sophisticated laboratory analytical methods.

MSM is an excellent dietary source of bioavailable organic sulfur. Doctor’s Best MSM features OptiMSM®, a highly purified form (99.9% pure) of methylsulfonylmethane (MSM). Since the amount of MSM found naturally in living materials is too small to be extracted, the MSM used for dietary supplements is synthesized. The makers of OptiMSM® developed a four-stage process to separate impurities including heavy metals and other contaminants and is 99.9% pure MSM. Each batch exceeds the United States Pharmacopeia (USP) monograph standards for MSM, and is validated by testing in independent laboratories.

How does it work?
Chondroitin sulfate and keratin sulfate, are long polysaccharide molecules called glycosaminoglycans. Chondroitin sulfate and the other glycosaminoglycans strongly attract water due to the negative charges of their sulfate groups. These negative charges also repel each other, creating spaces between glycosaminoglycan side chains where water can enter. This combination of solid and liquid gives joints a compressible qualitywhich may ultimately enhance healthy joint function.

In healthy joints, glucosamine is a fundamental building block for proteoglycans and glycosaminoglycans. Glucosamine sulfate (GS) helps to maintain joint health through its ability to both act as a component of and stimulate formation of glycosaminoglycans and the hyaluronic acid backbone essential for the formation of proteoglycans in healthy joints.

MSM contains two oxygen atoms and two methyl groups bound to a sulfur atom. As it donates its methyl groups, MSM enables important metabolic functions, including energy transduction and enzyme regulation. MSM’s use in joint stems from its organic sulfur support of the disulfide bonds that reinforce collagen fibers, a property that’s believed to promote joint integrity and resilience.

Why should I take Doctor’s Best Glucosamine/Chondroitin/MSM with OptiMSM®?
Healthy joints may get worn away by sports injuries, overuse, or wear-and-tear that can cause joint pain. Glucosamine helps stimulate the manufacture of proteoglycans in healthy joints. Chondroitin is a component of healthy joints that attracts water to the tissue, which helps the joint stay elastic and function as a shock absorber for joints. MSM is a natural sulfur to help form antioxidants and serve as a key structural nutrient in healthy joints and may help to give shape, strength and support to other tissues within the body. This combination of ingredients has been proven to support joint structure, function and comfort.*

Excellent product, but keep it away from chewers.
Style: 2.5" Ball
This is a very strong and effective launcher and could have lasted a very long time had my 9 month old not chewed the ball claw end off. I will buy again.

Our Dog Loves This Ball Thrower So Much
Style: 2.5" Ball
Works excellent for dogs that like to fetch! Our family dog loves this toy. He will bark and jump as soon as he sees us pick it up. The dog next door to us gets excited when he sees us play with our dog with this dog ball thrower. Its that good for dogs who love to fetch and run. Perfect for the young and elderly to play fetch with a pet dog. If you have back or shoulder problems works very well. You don't have to bend down and pick up a slobbery ball. Nope you use this to pick up, grip up and grab the ball. Wish every dog could have this ball thrower in their lives. It has changed the way we play fetch with our dog.

Good Pet Ball Launcher
Style: 2.5" Ball
I bought to throw balls for my Aussie. He does not like to tennis ball that came with it and chewed it up in less than one play time. The launcher seems to be of good quality and works well. We bought different balls made for launchers that work well.

Must-Have for Dog Owners (Whow have dogs that like to fetch)
Style: 2.5" Ball
Soon as this launcher arrived I went outside with the dogs to try it out. Long story short: This is a great fetch toy. I am able to launch the ball pretty far with little to no effort, and picking the ball back up is as easy as grabbing it with my own hand. The toy itself is very sturdy, so much so this is the only fetch-toy I'll ever have to buy. Considering how durable it is, I don't think I'll ever need to buy a replacement. I believe Chuck-It is the most popular option, and because this is the first fetch-toy I purchased, I can't really compare it to anything else. A few outlier reviews said the ball was difficult to launch, and I have to disagree. It has been so easy to use I can't possibly see what the problem is. And no, upper body strength is not a factor as I virtually have none. People can get great distance (Half the length of a football field by my eye) in one simple, easy motion. And if other products can launch the ball farther, so what? How far is far enough? Is your dog going to throw a fit because it went 40 meters instead of 50? No. They will not. For anyone upset this toy doesn't launch far enough, ask yourself this: Is the toy for their dog? Or the human who bought it? The bottom line is this: It feels like it's built to last, it's inexpensive, and it does what it is supposed to do. So long as a toy is "good enough" I don't see the point in splitting hairs and trying to determine which fetch toy is the absolute best. Saying it's good enough is a bit misleading though. I can't imagine how a dog toy like this could be any better. It's a must-have for any dog owner. Unfortunately, only one of my pups likes to fetch...
