SmartFlex® Senior

SmartSupplements by SmartPak

Our Price: $33.95 - $249.95
Price Match Guarantee Form: Powder
Maintenance Dose: 1 SmartPak Well

SmartFlex Senior was designed to support older horses in the 3 areas they need it most – joint health, digestive function and antioxidants for a healthy immune system.

For joint support, SmartFlex Senior provides 7,000 mg of Glucosamine, 500 mg of Chondroitin Sulfate, 50 mg Hyaluronic Acid and 12,000 mg of MSM. This formula contains the herbs Devil’s Claw and Boswellia, as well as the amino acid Phenylalanine, to help manage discomfort. To support healthy digestion and weight maintenance, SmartFlex Senior provides probiotics, prebiotics and enzymes. And because senior horses benefit from extra antioxidants, this formula also contains Vitamin C and the powerful free radical scavenger Super Oxide Dismutase. This outstanding formula is a customer favorite!

ALSO AVAILABLE IN PELLETS!

"My aging horse who is 20 yrs young , does so much better on SeniorFlex. Helps his joints, helps settle his stomach issues. I have tried so many other products and SeniorFlex helps him the best. Saves money with not having to purchase 3 different supplements. You get everything in one product. We don't give them anything else with his senior feed."

"I have been using SmartFlex Senior Pellets on my two older boys (26 and 29) with wonderful success. But then they got together and decided that the pellets were yuck! So we switched to the powder and everyone is licking their buckets clean again.
Thank you SmartPak for your wonderful customer service and helping me find a solution for my boys. You didn't even "push" your own product, but gave me ALL the options! I'm extra happy I was able to stick with what WORKS!!"

"I had my reservations about this supp. when I first ordered. I have a 36 year old arab mare that is the pickiest horse I have ever encountered. She will go days without eating if there's something she doesn't like. But! She loves this supplement! Not only does she eat it but in the two months I have been feeding she has had an obvious difference in movement and weight. My mare has three displaced disks in her lower back so to find something that is cheap, palatable, and works is a dream come true!"

"This is a very good product. I use it in my older lesson horses and recently started my older event mount a few months ago and have noticed that she is much more supple and willing to work even after cold nights. I plan on starting all of our horses here on some form of smartflex product due to the difference it has made in my guys that are currently on it."
