What exactly is Flex-N-Action?

Flex-N-Action is a scientifically-developed joint supplement that delivers four targeted connective-tissue nutrients in a single daily ounce. Each serving supplies 5,000 mg of glucosamine HCl, 4,000 mg of chondroitin sulfate, 2,000 mg of MSM and 40 mg of hyaluronic acid. The combination is built to support cartilage, cushion the joints and act as a natural lubricant for horses of every age and discipline.

Who makes Flex-N-Action?

Flex-N-Action is a Farrier's Magic™ product, and the brand carries the slogan "Excellence in Equine." Farrier's Magic began on a horse farm in Berlin Center, Ohio, at the hands of an entrepreneur with a heart for horses and a background in pharmacology -- an avid harness racer who perfected liniments, hoof creams and supplements in his barn "laboratory." Today those original recipes are produced and distributed by Republic Mills, Inc. of Okolona, Ohio, a family-owned agricultural manufacturer operating under third-generation leadership.

What goes into the pellet, and where is it made?
Flex-N-Action is built on a palatable timothy hay base, so the active joint nutrients are carried in a pellet most horses "gobble right up" rather than a powder that has to be hidden in feed. It is proudly made in the USA with domestic and imported ingredients. The maker's mission statement is plainly stated: "High Quality Ingredients for High Quality Products to provide a High Quality of Life for the horses we serve."

How does Flex-N-Action support the joints?

The formula pairs glucosamine HCl and chondroitin sulfate -- the two building blocks of cartilage -- with MSM, a source of bioavailable sulfur tied to connective-tissue and inflammatory comfort, and hyaluronic acid, the molecule that gives joint fluid its lubricating, shock-absorbing quality. Farrier's Magic describes the blend as a "scientifically developed combination of nutrients" that fortifies connective tissue and acts as a natural lubricant. It is positioned for horses facing the strains of aging, training and competition.

Which horses is it developed for?

Flex-N-Action is developed for horses of all ages and all levels of training -- from aging equines and senior pleasure mounts to barrel horses, harness racers and other performance athletes that stress their joints. Because it is fed at a steady maintenance ounce rather than a loading-dose regimen, it suits both daily joint maintenance and hard-working competitors. The label notes it is for animal use only and should be kept out of the reach of children and animals to avoid unwanted consumption.

How do you feed it, and what does it cost?
Directions are simple: administer 1 oz daily, where one scoop equals one ounce. Flex-N-Action is sold in a 2.5 lb tub priced at $41.95 on the Farrier's Magic site, with larger 11 lb and 50 lb sizes also offered. It can be purchased directly at farriersmagic.com and through major equine retailers including Chewy, Tractor Supply Co., SmartPak, Valley Vet and Schneiders Saddlery.

An avid and well-known harness racer in his day, he tested and perfected liniments, hoof creams and supplements in his barn 'laboratory.'

Which horses is Flex-N-Action best suited for?

It is developed for horses of all ages and all levels of training. That includes aging equines and senior horses showing joint stiffness, as well as performance horses such as barrel racers, harness racers and other athletes that put repeated stress on their joints.

How does hyaluronic acid help my horse's joints?

Flex-N-Action provides 2,000 mg of MSM per serving. It is included as part of the brand's 'scientifically developed combination of nutrients' that fortifies connective tissue and the joints.

Is Flex-N-Action a pellet or a powder?

It is a pellet. Flex-N-Action is built on a palatable timothy hay base so the joint nutrients are carried in a hay-flavored pellet that, in the brand's words, your 'trusty steed will gobble right up.' This makes it easier to feed to picky horses than a loose powder.

Can I feed Flex-N-Action to a young or in-training horse?

Yes. The product is explicitly developed for horses of all ages and all levels of training, including horses in active training and competition, not just aging horses. As with any new supplement, introduce it as part of your horse's regular feeding routine and follow the 1 oz daily direction.

How long until I see results from a joint supplement like this?

Nutritional joint supplements are fed daily over time rather than producing instant results, so consistency at the 1 oz daily serving matters. Many owners evaluate joint support over several weeks of continuous feeding. Because individual horses respond differently, monitor your horse's comfort and movement and consult your veterinarian about your specific horse's program.
