Key substances in Acti-Flex work together to improve performance by increasing the horse's supply of joint-lubricating synovial fluid, which repairs and strengthens body parts that running puts under high stress. Glucosamine Sulfate, Chondroitin Sulfate, Methylsulfonylmethane (MSM), and Superoxide Dismutase occur naturally in the body, serving the function of repairing joints and many other tissues.

Hyaluronic Acid (HA) plays a critical role in maintaining healthy joint synovial fluid and preventing the deterioration of aging, over worked joints. HA has a high daily turnover so large amounts are needed to maintain proper levels within the joints. HA is also shown to influence cell movement, blood vessel formation, critically involved in healthy wound healing and serves as an antioxidant.

By supplementing what a horse produces for itself, Acti-Flex greatly speeds the body's self-repairing processes. MSM adds a powerful ability to improve sulfur bonds, which are an essential component of all connective tissue. Ascorbic Acid (Vitamin C) is a key to optimizing bioavailability of the other ingredients, as well as being an essential antioxidant. Boswellia Serrata is an herb that is proven to reduce inflammation.

Directions for use:
2 ounces a day for the first 5-17 days. Thereafter, the maintenance dose is one ounce a day. Either in regular feed or oral dose syringe.

Great product


Works great




Love This Product


I have been giving the product to a young off the track Thoroughbred and he is moving a lot easier.I also just started giving it to a family members horse that is a 31 year old Peruvian Paso that fractured her right mandible 16 years ago when she was kicked by another horse. She has few teeth left and has been eating soaked hay cubes. I noticed that her neck seemed very stiff and I thought right away Arthritis in her neck and probably her Jaw. I started her on this and also raised her feed bucket even with her head set and she seems to be eating so much better with less bolus dropping from her mouth.

It smells good, my horse loves it.




Highly recommended!


I would highly recommend product to anyone who is looking for an overall join supplement! It has made a huge noticeable change in my made after just 10 days of use. She absolutely loves it, cleans her bowl, and is moving more fluidly and loosely than she has in the past 3 years! Absolutely love this product!

We use this product daily in the horses feed. Made a big difference in my horses joint stamina throughout the year




Must try!


Picky eater even licks the bucket after breakfast.

I've had my guy on Actiflex for over 5 years. I've compared the ingredients to more expensive joint supplements on the market and Actiflex is equal to or better in all the key ingredients needed to assist in joint function.

My favorite joint supplement


My horses leave the powder or pellet additive. The liquid they get it all.

How much do I give a 38lb dog?


Dosage: 1 tsp (5 ml) per 50 lbs. You can give more than this in extreme severe cases for loading dose for several weeks or until you see ​clear signs of no limping or pain. Usually within 3-5 days you will begin to see change. If not, increase the dosage.


I own a St. Bernard, who weights approximately  160 pounds. Who tore her acl.I give 2 tsp 2 times a day. Sent via the Samsung Galaxy S7 active, an AT&T 4G LTE smartphone


For dogs 25-50 lbs. 1 tsp daily loading dose for 5 days and 1/2 tsp daily for maintenance.


Would this be safe to give to an HYPP horse?


It is always best to consult your veterinarian to see if there could be any type of adverse reaction when adding a dietary supplement to horses with an existing condition.


How much boswalia serrata is actually in this product? Thanks


It's not listed in the guaranteed analysis where they list amounts and is third last ingredient on ingredient list Sent from my Windows 10 phone


Per Coxlabs.. There is not enough in milligrams of Boswellia to list it on the label under the amount. So not much at all.

Boswalia Serrata isn't mentioned in the guaranteed analysis. The small amount may work in conjunction with the other ingredients to reduce inflammation.


Can this be given to dogs? I read somewhere that they gave this to their dog (instead of the k-9 formula).


I've never used it for dogs and since they already make a canine formula I think it would be pretty easy to just compare the two. Their digestive systems aren't quite the same so I would want to make sure that the horse version was okay to give my dog before experimenting. That being said, most things that I've fed my horses over the years are perfectly safe for my dogs. Is there a reason why you don't want to use the formula designed for dogs? Sent from my Sprint Samsung Galaxy S7.


I do. If you compare the ingredients with the K-9 formula, its the same thing, Just make sure you give ALOT less then you would for a horse!


I have read in product reviews that people have had successful results giving this to their dogs. And this dates back prior to the development of the canine formula. Sent from my iPhone


No clue only give to my horses. I'd have to ask a veterinarian or the manufacturer Sent from my iPhone


The ingredient dosage for Acti-Flex 4000 is targeted towards equine. For Acti-Flex K9, please refer to item #21075.

I've been giving this formula to my 2 Airedales for years!


Expert answers - are you joking? The product is either approved for human consumption or it's not. No expertise required there, just available information. I like your company, but these answers are pants.

Nancy the Newbie

This product is not marketed for human consumption, so we cannot ethically recommend it for that purpose.

Customer Service

Is this approved for human consumption?


We recommend consulting your doctor before adding any new supplements to your diet.

Customer Service

I have a mini, he weighs approximately 400 lbs. How much of the Acti-FLex 400 do I give him daily?


The average horse receives 1 to 2 oz. daily. It is recommended for the safety of your horse that you ask your veterinarian what adjustment should be made to the average dosage.
