Acti-Flex Senior by Cox Labs is a nutritional supplement specifically formulated for the "old timer" to help them stay flexible, comfortable and maintain a healthy weight. It contains the same joint benefiting nutrients as Acti-Flex and includes probiotics to help older horses compensate for reduced digestive efficiency so the nutrients can properly be digested to benefit all vital systems. This is particularly beneficial for older horses that may have difficulty gaining or maintaining a healthy body weight.
Acti-Flex Senior is manufactured in an alfalfa-based powder that proves to be highly palatable.
Guaranteed Analysis Per Oz: Lactobacillus 93,750 million CFU Glucosamine Sulfate 8,000 mg. Chondroitin Sulfate 4,000 mg. MSM 3,000 mg. Ester C (Ascorbic Acid) 1,000 mg. Hyaluronic Acid (HA) 125 mg.
Feed 1 oz twice per day for the first 7 to 14 days then reduce to a maintenance level of 1 oz per day. A 1 oz scoop is enclosed. The 16 lb tub will provide up to a 256 day supply for one horse.
I own an equestrian center with boarding and a lesson program. Acti Flex Senior is a great product, it keeps my school horses going at peak performance well into their 20s. One of our best school horses turned 30 this year. Thanks for making such a great product.

Has it all
I have researched many joint supplements out there and have tried at least 10 or more brands on several different horses with varying issues and this brand is the one I found that not only worked the best, but was the least expensive for what you get. My yearling went on this after surgery even though its for senior horses. I used it because of the added probiotics and weight builder. They have regular Acti Flex without these ingredients that I could switch to if he put on too much weight. I have seen the difference this supplement makes in the older, stiffer horse and it definitely works.
- K. Smith, MD
Read the ingredients and compare this
product with other joint supplements!!!
All that and they like it!
I have used this product for 6 horses for years. Very pleased with the support it offers.

Senior horse health with Actiflex
Im not sure if this product is the main reason for my horses health but I have a 35 year old mare that is still trotting and cantering beautifully. Ive been supplementing her feed with Acti-flex ever since she had a stifle injury over 13 years ago. Due to Shawnees incredible health there are other people at my stable using this product with satisfying results.
- Beth Cruocher, OH
I love Acti-flex Sr. I have 4 older horses on it. Ranging from 15 to 26. They all act like youngsters on it. Some dont have any joint problems but I believe it because Ive been giving this to them. Some of them are arthritic and were very sore before I started them on it. It is the best product for the price!
- Michelle Newton, NC
Love this product!!
I use this product on 7 horses and I am satisfied it helps all 7. Highly recommend it.
- Sarah G, NY
Actiflex sr is a great product!
Had really good and fast results with actiflex senior. Saw improvement within a week.
does active flex really help
yes and the easiest way to tell is to put your horse on it for approximately 2 to 3 weeks and then take them off of it and if you see a difference you know that it has helped I personally use it for all 5 of my senior horses
Expect great results from Acti Flex Senior Powder
I have a 29 year old gelding and a 24 year old mare and 2 other young horses. I have been feeding the 2 older horses Acti Flex Senior for about 3 years and the reason is simple. It works. The 29 year old is still head of the herd and RUNS to greet me at each feeding. The older mare suffered an injury in her youth and I really think its this product that is keeping arthritis from setting in. Both of these horses are still active on the trails and other miscellaneous pleasure activities. Its easy to feed, they like the taste and never waste it. I am a very satisfied customer!
- Marcia, KS
Great product for older horses
Ive had several horses 14+ years old on this product. Can tell a huge
difference in their comfort level.
- Karen, RI
excellent product. I have using Actiflex for my horses for several years. This product is not only effective but the most inexpensive supplement of its kind. Horses love it. Very palliatible to the horses. No waste.
The absolute BEST!
I have all 3 of my horses on this wonderful supplement! Their ages range from 24-16. It has made their overall health and quality of life much better!
- Debbie, FL
Good for the old boy!
I believe that Acti Flex Senior Powder is an extremely good value for the price. It seems to have helped my 28 year old foxtrotter gelding maintain his weight late in the winter and into spring . I will be paying close attention as I ride him more often with warm weather, but so far I feel this is a great supplement for the overall health of my old friend.
- Bonnie, MO
My school masters are riding like young horses.
I have been using Acti Flex Senior for several years for my show horses and the results are fantastic.I have a 26 year old Morgan still going strong and eventing! The probiotic is an added bonus.
- Pamela McGeough, VA
Its really does work!
I have been using Acti Flex for 7 years and know that it works. I have 5 senior horses with various ailments and a very old cow that I use it on. I have repeately seen a benefit to this product and proof is easy to see, just take them back off of it and you can tell the difference immediately.
- Mellinda, FL
This supplement worked wonders on my Eventer
ACTI FLEX SENIOR POWDER - 16 LB
This is a great product. Its one of the only ones that has Hylauronic acid Glucosamine chrondroiten msn probiotics vitamins and minerals. I have been using it for many years with only great results.
- Lisa, CA
Have used this supplement for years now on horses 13 years thru 24, all still active riding and driving. All like it highly palatable no waste.
- Sarah, NY
Cant get any better then 5 star.
The best joint supplement I have ever used. I have four horses, two at 15 years of age and two between 27 and 32 years. Acti Flex senior powder has made a huge improvement with all my horses, no more cracking and popping when they walk, very little stiffness. I swear by the product. Its less expensive then the leading brands too, making it more affordable for me to give to my four horses.
- Horse-nanny, NM
Best all around Senior horse supplement
Acti Flex Senior Powder has really helped my 26 year old retired barrel horse mare stay sound, comfortable, in good weight and body condtion. I have recently started giving it to my 15 year old barrel horse mare too. This product is a superior all in one senior supplement, and the digestive aids and probiotics really help the aging horse absorb and utilize the nutrients in the supplement and their feed. I will continue to use and recommend this product as long as I have horses!
- Elaine Williams, NC
I believe actiflex/actiflex sr to be the best joint supplements for your money. I have never been disappointed in any cox vet lab products-my horses have been on actiflex & hoof secret for years & the results have been great!
- Cheryl Froman, SC
One happy cowgirl!
I have been using the Acti-Flex powder for several years now. I have had good results with it. The horses I use it on currently are 15, 19 and 24 so I switched to the Acti Flex-Senior powder and I have been equally happy with the results. All of my horses are very happy and run and play just as hard as my young ones. It helps keep them young and feeling good. They also seem to like the taste and eat it just fine.
- Michelle Newton, NC
Effective and reasonably priced
I have several horses that take actiflex. I can notice a real difference in their joint comfort. The only thing I dont love is that the dosage of MSM is fairly low; I add additional MSM.
Great Supplement For Senior Horses
I purchased this supplement because my vet highly recommended it with the ingredients it had. I have noticed a big difference in my now 28 year old horse. I will continue to give her this to make her senior years better. Check it out and see what you think and consult your vet. Im sure they will agree.
- Peggy Fugate, OH
This is a great product at a good price.
- Sarah Gill, NY
My 25 yo Thoroughbred is in great health other than some arthritis in her hock. Shes been on regular Actiflex for a couple years, but I decided that the Senior version might be better given her age. She seems to be doing really well. I returned home after 6 weeks. She hadnt had much exercise, other than pasture time, while I was away, but seemed to be doing well on our first ride after my return.
- Marc Kaufman, FL
20 year old feels like 10 year old again!
My competition gelding is now 20. He has won 2 World Championships and my children said he was starting to slow down. So I started him on ActiFlex. He is like a new horse! We are going to another National Championship next week. We hope to continue having fun riding and WINNING!
Already notice a difference!
I just started using this a few days ago on my 29 YO mare and caught her kicking up in the arena last night. She hasnt done this in months! I was beginning to worry about her, so am glad shes got some energy back.
A Superior Joint Compound!
After using ActiFlex for several years I switched to ActiFlex Senior when my Paint mare turned 15. Wow! is all I can say. She went from Good to Superior. No more clicking and ticking, no more little stumbles, and no more hardheaded stubbornness on certain portions of the trail. I am so sold on ActiFlex Senior. Easy to feed, highly palatable, affordably priced, and incredibly fast acting. What an awesome product!
- Carol, MD
great product--multiple joint health ingredients at higher levels than many competitors and all at a reasonable price
Superior supplement for Senior horses
ActiFlex Senior is a superior supplement for senior horses, I have been using this product for three years for my 26 year old AQHA barrel horse mare, her body condition and fitness level are that of a horse at least 10 years younger! The added probiotics in this supplement really help the senior horse utilize their rations and hold their weight. My mare overcame a suspensory ligament injury that she sustained as a 23 yr old, and she is sound and fit. I attribute that amazing recovery to the ActiFlex Senior.
- Elaine Williams, NC
Ive used this for years and find it beneficial to my horses and a good value for my pocket.
Its a win-win!
- Sarah, NY
My horse has been on this for about two months. He has arthritis in his hocks, so hes never 100% sound. On Acti-Flex Senior he runs in from the field like the 5 yr olds!
- Nic D, PA
Actiflex is great product at great price
I switched both of my horses to this product from another, much more expensive, joint supplement. Both are doing great and the price is helping my budget.
Acti Flex Senior helps Lindy
My retired Peruvian mare, Lindy, is loaded with arthritis in her front end due to a broken shoulder at an early age. She is now being ridden three times a week for at least 30 minutes on even ground in gait. She is moving smoothly with her ears forward and a happy look on her face. Acti Flex Senior has made a huge difference in Lindys quality of life.
Acti-Flex Senior Powder
My horse didnt want to eat it on his pelleted grain while on the loading dose, but now that hes cut back to 1 scoop a day he has been fine. It really helped his hocks, he now runs in from the field fluidly.
we use Acti flex and acti flex senior at or barn. absolutely does everything it says it does.
- pam, PA
Fantastic joint support for an affordable price!
This is my second year using this product and I am more than happy with the results this has given my 19 yr old gelding. Hes behaving like a frisky 6 yr old! No more joint pain and he chases the young boys around the pasture! The Acti Flex Senior has given him a new lease on life. I highly recommend this product for the older horse. Thank you so much!
- Diane S, IN
Love Acti Flex Senior! A HUGE benefit to my senior horses!
This product amazes me! I have 5 horses on it! 13, 14, 15, 15 & 16. They are all moving sound on this product with no sensitivity issues like they were having! My gelding has severe low ringbone and on this product he is a new guy! I love it! Thank you Acti Flex!
- AJ, OR
Acti Flex Senior
I have been using this for over 3 years on two of my horses. The one mare is 30 years old and doing very well. We are using it as a preventative for my other 14 year old horse. It comes in just the right size.
- Carol, OH
I love this stuff
This product is excellent for horses with arthritis issues, especially the senior horses. I have had great results within a week after feeding Actiflex. I highly recommend.
- Deb S., WI
Acti Flex Senior Powder is AMAZING
I tried this formula for several of my horses ranging from 12-16. I can only say that the results have been DRAMATIC and each horse on this is moving excellent! From my trail horse to my show horses this product has worked wonders! I highly recommend this to anyone who has a senior horse that needs a great supplement to help keep them sound. Thank you!
- A Korte, OR
Love this stuff!
I have a mare with very crooked rear legs that is developing ringbone in the front end. She looked stiff and unhappy before adding Actiflex Senior to her diet. She was running and playing with her pasturemate this morning like a 3 year old!
Ive been using this product for over a year now. I love it for my many senoir horses. Cost per horses is good and it seems to keep my older horses going strong!
The Best Bang for Our Buck!
Have been a happy user of ActiFlex Senior for over 2yrs now. Very palatable for Mr. Picky, and he bucks and plays like a 6yr old. Shh! Dont tell him he is 23!!! Thanks Big Dees! :-
- Jen Machalicek, TX
Helps at a good price
Ive been using this product now for several years and it works as well, if not better, than some of the pricier brands I had earlier tried. They like the flavor and never leave it at the bottom of their buckets.
Great joint supplement. Really made a huge difference in several of our horses. Highly Recommend!
- Jackie Hackett, NY
Acti-Flex Senior Powder
We have been using Acti-Flex Senior Powder for many years with wonderful results. We have 26 and 27 year old geldings that have over 600 and 800 AQHA points each. They are still sound, winning, and showing in pleasure, horsemanship, trail, western riding, and showmanship. I am a firm beliver that the Acti-Flex helps them. All of our horses receive Acti-Flex as soon as we start riding them as 2 year olds. The young horses get Acti-Flex as a preventative, and it definitely helps the older horses in being happy and sound.
- Roy Schwab, WI
Actiflex Sr. works wonders for Arthritic horses
I have all the older horses in my stables on Actiflex Sr. We have seen great improvement in all. Love the stuff and will keep using. I highly recommend.
Excellent Joint Supplement
I started my 2 horses on this supplement a while back, and when people saw the results I was getting, they wanted in. We now have 12 horses in the barn on Actiflex. Great product, great value, and Big Ds always has the lowest price!
- Jackie H, NY
While I m a little disappointed that the price has risen by 50% in the past year, this product is still leaps and bounds above anything else with regard to content-- glucosamine, chondroitin,and HA amounts are more than some products that cost over $2 per day and this one comes in at less than $0.50 per day-- my geriatric mare is very fickle about what I put in her grain and she eats this up without a problem-- its just great all around!
I have a 19 year old trakehner who has a very rocky medical history. Severe navicular, two torn deep digital flexor tendons, lyme, ringbone, etc. Just days after putting him on Acti-Flex senior, he was bucking, broncing, and playing like I have never seen him do before. I have had him for ten years and he was never one to play but ever since I started him on the supplement I have seen a world of a difference. I highly recommend this supplement! It has really made a world of a difference in my old boy.
- Kate, MA
Acti Flex Senior
Good price...really helps my retired show horse.
Okay, but not the best results
Although the ActiFlex senior has everything and more in it that the supplement that I previously had my senior horse on, the results were a bit disappointing. Within 2-3 days of switching him to the ActiFlex feeding 1 scoop twice a day he was more stiff and not moving fluidly at all... and the creaks and pops from his hocks returned. And that was even with additional MSM to bring it up to a full 10,000mg twice a day! I had pretty high hopes for this supplement since I know others who have liked the results that they have seen, but it is not for my guy. Maybe if he was younger with less joint/arthritic issues it would work better. I will continue to give it to him at night and give his other joint supplement in the morning because I certainly dont want to waste it all! :, but I have seen MUCH better results with different products, and though they cost more than this one does, they also show results. So overall, it would probably work well for a more with mild joint issues... but it sure does smell good and my horse licks it all out of his feeder, so palatability isnt any issue :
I use this product for my 28yr old retired QH show mare and she can lope to the back of the field and buck in small circles to stay outside. Has given her more mobility and arthritis pain relief
- SHERRI, OH
ACTI FLEX SENIOR POWDER- 16LB
This is an excellent product, I am using it for my 25 year old AQHA retired barrel horse mare who is a picky eater but licks the feed pan clean when the ACTIFLEX SENIOR POWDER is mixed with her ration. I particularly appreciate that this product contains probiotic digestive aids for the senior horses less efficient digestive system. This product has helped my great retired barrel horse remain mobile and comfortable although she has arthritis and swelling from an old tendon injury.
- Elaine Williams, NC
Acti Flex Senior Powder
I had previously used the Acti Flex liquid supplement but actually prefer a powder because of convenience. After comparing the ingredients of Acti Flex Senior with many different supplements on the market, I felt that Acti Flex Senior was the right supplement for my horse. Being a senior horse he needs the prebiotics and probiotics which Acti Flex Senior contains. I do think that the MSM needs increased in the Acti Flex Senior so I add extra MSM to obtain the recommended daily amount per day. My horse eats the Acti Flex Senior supplement in his grain and I have not had a problem with his not eating it. Overall, I feel it is a good product for the money.
I had my horses on another supplement, that was less effective and more expensive. Since switching over, the horses are better, and 9 of my barn mates have added their horses to the list. Great product.
- Jackie H, NY
we use a joint supplement all the time and to get one with everything you need in one supplement is a big plus. great value!

Actiflex Senior Powder versus Actiflex Powder
Your delivery service is EXCEPTIONAL! Received my product the next day with regular shipping rate.
This time I ordered Actiflex Powder instead of Actiflex Senior Powder. My senior horses are easy keepers and do not need the extra fat to retain weight. Actiflex Senior Powder has better aroma than Actiflex Powder. The Senior smells like fresh apples. The regular powders aroma is not enticing. Will let you know how my horses respond to it.
