Tight Joints Plus has been researched and in the process of development for over 20 years! It contains 6 ingredients to support comfort and fight inflammation! Many users become Dealers! Use it and see why!

What Was The Inspiration For Tight Joints Plus?

The creator of Tight Joints Plus, Tony Loften, is a horseman with 30 plus years of experience with race and barrel racing horses. Tony was not looking to create a product for retail, he wanted a product that would work on his own horses, without having to turn to the vet every time he needed a joint issue or pain issue treated. He had tried many joint products that claimed to treat joint issues without success. He knew it was time there was a joint supplement on the market that not only treated minor joint issues but also severe issues and overall made horses feel better. Tight Joints Plus was an idea to take your everyday joint supplements, natural pain relieving supplements, HA supplements, and combine it all together as one, with amounts of each ingredient that would make a difference. Not only will our supplement help you to manage pre-existing conditions, it can also help to prevent future damage by making your horse more comfortable each and every day!

What Sets Tight Joints Plus Apart From Other Joint Supplements?
Tight Joints PLUS's combination of ingredients were put together for maximum efficacy. It works first on the inflammation with the 6 ingredients to support comfort and fight inflammation. Anytime there is inflammation, your horse will experience discomfort, so we added natural ingredients that support comfort and relief to your horse. When the inflammation is gone then the 6 joint rebuilding ingredients can go to work repairing. You will not find another product on the market that has this combination of ingredients, with the levels of active ingredients in a single dose. This is why it works!!

What Benefits Do These Ingredients Offer and How Where They Formulated?

The equine nutritionist that formulates Tight Joints Plus has studied for many years that in order for joint supplements to work the first step is to reduce the inflammation. When the inflammation is gone the joint repairing agents can begin to do their job. The lubricating ingredients of Tight Joints Plus help the joint with just that, lubrication to prevent inflammation and cartilage damage.

Glucosamine- The basic building block of connective tissues and fluids. Works in treating osteoarthritis and rebuilding damaged cartilage.

MSM- Natural anti-inflammatory, helps with arthritis pain, increased circulation, and also benefits soft tissue.

Ascorbic Acid- Powerful antioxidant, reduces the level of uric acid in the body which can lead to arthritis and joint pain caused by inflamed joints.

Shark Cartilage- Reduces inflammation, regenerates worn cartilage, reduces pain, & stiffness.

Boswellin- Natural pain reliever.

Devils Claw- Natural anti-inflammatory

Yucca-Natural anti-inflammatory

Copper - Anti-oxidant, required for the development, repair, and maintenance of joints, soft tissue, and other connective tissue.

Hyaluronic Acid- Enhances healing, anti-inflammatory, repairs cartilage damage, and improves joint function.

Manganese- Necessary for cartilage formation.

Vitamin E- Natural anti-oxidant

What Is The Recommended Feeding Dosage For Tight Joint’s Plus?

Tight Joints Plus is a Powder and has a 1/2 ounce scoop included in the container, feed 1 scoop for the first day for horses to get used to taste and texture. Day 2 through Day 14 feed 2 scoops and then go to 1 scoop on day 15 for maintenance. 2 scoops is recommended for when a horse has acute inflammation.

Is It True That Many Tight Joints Plus Dealers Are Customers?

Yes, many of our dealers are very satisfied customers and have been using it long before it was available through feed stores. In fact, that is how we got our start in the stores. Store owners were buying it for their own personal use and they wanted to carry it.

What Is The Difference In The “Show Formula” Of Tight Joints Plus?

The show formula does not have Devils Claw in it. If you are involved in USEF events, then the show formula is the way to go as it will not ’test’. We want to be able to help horses in every discipline and level of competition. We realize with certain types of shows and competitions comes restrictions to what you can give your horse to alleviate them from pain and arthritis. With this in mind we designed the the show formula to meet the USEF guidelines. We removed the Devils Claw and increased the amount of MSM. Ultimately we replaced one anti-inflammatory with another. Whether you want to feed the show formula year around or feed the regular Tight Joints Plus the majority of the time and switch to the show formula a period of time before the show, we have made it possible to keep your horse feeling its best while abiding by the USEF rules.

Can My Horse Enjoy The Benefits of Tight Joints Plus For As Little As 89 Cents Per Day?
Yes! Despite the tremendous results, Tight Joints PLUS is very affordable. It was made BY Horse owners, FOR horse owners— that want the best in results and comfort for their horses. It can be fed for as little as .89 cents per day.

Is There A Case Study To Read About?

We did a case study on a 19 year old Thoroughbred Gelding that was injured on the track as a 4 year old. Many products were used over the years to reduce the inflammation and the size of the knee to keep him comfortable during his second career. Eventually nothing was keeping him comfortable anymore and he was no longer sound enough to ride let alone compete. In just 30 days on Tight Joints Plus the gelding is not only sound again but you can visually see the results! No other supplements or pharmaceuticals were used in the 30 days, only Tight Joints Plus. He is now sound and being ridden in preparation to compete again.

What Do Horse Owners Say About Tight Joints Plus?

Last summer we started using Tight Joints PLU S on my 14 year old gelding "Dude", my 7 year old mare and our 5 year old that had a suspensory injury. With in two weeks of starting Dude on it he was winning Wbra Opens and running mid 17's again. He even wanted to run hot laps to warm up in between double header barrel races... his normal M.O. is to make me feel guilty by acting exhausted if I had to run him twice. My 7 year old started needing hock injections at 5 and hasn't been injected since we started her on this supplement and our 5 year old has not had any problems with his leg since his injury. We are very happy with Tight Joints PLUS. They eat it no problem, we only have to feed it once a day and we can give it to more then one horse because WE CAN Afford TO!

Linzie Walker, Wpra Barrel Racer

I have been an equine veterinarian for over 20 years which includes treating top level performance horses. I recommend Tight Joints PLUS to all of my clients as my preferred joint supplement. You can really see the difference it makes in a horse and my clients love it.

Dr Lutz Harst, DVM

I bought Tight Joints Plus only 1 1/2 weeks ago and my horse is already showing me such great progress! He is an older guy with a bone chip in his knee, he has much more flexibility in the joint and is much smoother when riding him. For the first time in a long time he bolted out of my hand when I was turning him out, which usually would make me angry but I was so excited to see him feel well I didn't even care =0) Thank you for allowing me to find something so reasonably priced that makes my guy feel so great!

What exactly is Tight Joints PLUS?

Tight Joints PLUS is an all-natural equine joint and soft-tissue supplement built around a patented formula that has been in development for more than 20 years. It evolved from the company's original product, Tight Joints PLUS MSM/complex, which longtime users had so much success with that the makers re-engineered it for the modern performance horse. Beyond lubricating and supporting the joint, the upgraded formula was designed to also support a healthy inflammatory response, helping horses maintain flexibility and recover from the daily demands of training and competition.

Who makes this joint formula

The product is produced by Tight Joints PLUS, based in Auburn, Washington (2828 Emerald Downs Dr, Auburn, WA 98001), and is formulated by an equine specialist team with deep roots in performance and racing. It is manufactured in the USA with no fillers and is trusted by veterinarians and dealers nationwide. The company runs a full product line under the same brand: the Original Formula, the show-ring Tight Joints PLUS Gold, a canine version, and a line of hemp products for animals and humans.

The patented formula and its ingredients

Each serving of the Original Formula delivers a heavy-hitting nutraceutical stack: 10,000 mg Glucosamine, 5,000 mg MSM, 8,000 mg Ascorbic Acid, 1,000 mg Shark Cartilage (20% chondroitin sulfate), 1,000 mg Boswellia, 1,000 mg Yucca, 1,000 mg Hyaluronic Acid, 500 mg Devil's Claw, 200 mg Copper, 150 mg Manganese, and 150 mg Vitamin E. Glucosamine, shark cartilage and manganese rebuild cartilage and connective tissue; hyaluronic acid restores the synovial fluid that lubricates the joint; and Boswellia, Yucca and Devil's Claw target the body's natural inflammatory and pain response. There are no fillers diluting the dose.

How Tight Joints PLUS works

The formula works in three main ways: it manages the inflammation caused by daily work, maintains the synovial fluid that lubricates the joints, and supports the structural integrity of joints and connective tissue. The team's research found that inflammation must be controlled first, because only once it subsides can the joint-supporting agents do their real job of rebuilding ligament, tendon and joint health. The feeding protocol reflects this: a loading phase of 2 scoops daily for 14 days, then a maintenance dose of 1 scoop daily per roughly 1,100 lbs of body weight (the enclosed scoop equals 1/2 oz).

Who it is for, including show and rodeo horses
Tight Joints PLUS is aimed squarely at the performance horse — barrel racers, rodeo stock, thoroughbred racehorses and hard-working geldings and mares whose joints take a daily pounding. For competitors who must stay clean under drug rules, the company also offers a USEF-approved Show Formula (Tight Joints PLUS Gold), so riders can support their horses at peak performance without jeopardizing eligibility. Real customers report acute swelling resolving, hock injections becoming unnecessary, and aging horses returning to winning form.

Pricing, where to buy, and the dealer program
The Original Formula comes in 2 lb, 8 lb and 16 lb sizes priced at $72.00, $252.00 and $446.00; the full Tight Joints PLUS line runs $74-$446 and Tight Joints PLUS Gold runs $74-$252. It is served through 100+ stores and major catalogs and websites including Horse Health USA, Riding Warehouse, Best Horse Gear and Katie's Coast to Coast, with wholesale through VSI, Inc., RJ Matthews Company and Animal Health International. Many users love it so much they become dealers — to order, learn more, or ask about wholesale and dealership options, call (888) 423-7295 or email (hours Monday-Sunday, 8am to 4pm).

Who created Tight Joints PLUS?

Tight Joints PLUS is produced by an Auburn, Washington company and formulated by an equine specialist team with extensive performance and racing experience.

The brand operates under the Horse Power Feed contact (horsepowerfeed@gmail.com).

Is there a show-safe or USEF-approved version?

Yes. The company offers a USEF-approved Show Formula, marketed as Tight Joints PLUS Gold, designed to support horses at competition without jeopardizing show eligibility. This lets riders maintain joint support right through show season. The Gold line is priced from $74 to $252 depending on size.

What sizes does Tight Joints PLUS come in?

The Original Formula is available in 2 lb, 8 lb and 16 lb sizes. The 2 lb tub provides roughly a 60-day supply at the maintenance dose for a 1,000 lb horse, while the larger sizes extend that supply considerably. Tight Joints PLUS Gold and the canine version are sold in their own size options.

Is Tight Joints PLUS good for barrel racing horses?

It is widely used by barrel racers and is featured in InfoHorse's barrel racing category for exactly that reason. Customer testimonials describe a 19-year-old barrel horse whose acute rear-leg swelling went down after three weeks on the product, after which he returned to placing in the 1D. Another rider reported breaking an arena record on a mare she ran on Tight Joints PLUS. The supplement is formulated for the hard, repetitive joint stress that barrel and rodeo horses experience.

Does Tight Joints PLUS contain fillers?

No. The company specifically markets the product as having no fillers, meaning the full labeled milligram amounts of glucosamine, MSM, hyaluronic acid, shark cartilage and the other active ingredients are delivered in each serving. This is a key differentiator the brand stresses against competitors whose products may be diluted.

What does the Hyaluronic Acid in Tight Joints PLUS do?

Hyaluronic Acid (dosed at 1,000 mg) helps maintain the synovial fluid that lubricates the joints. Healthy synovial fluid improves the joint's viscosity and cushioning, which is central to the product's claim of maintaining flexibility and reducing daily-work discomfort. It works alongside glucosamine, shark cartilage and manganese, which support the cartilage and connective tissue itself.

Can Tight Joints PLUS be used for dogs?

Yes. The brand makes a dedicated canine version, Tight Joints PLUS for Dogs, applying the same joint and soft-tissue support philosophy to dogs.

Veterinary input also informs the brand's emphasis on managing inflammation before rebuilding the joint.

Is it safe for pregnant mares?

According to retailer feeding information, Tight Joints PLUS has not been tested on pregnant mares, so the company does not make claims for that use.
