About CompleteHA

CompleteHA is the ultimate and most effective joint supplement, containing a powerful combination of Glucosamine, MSM, Chondroitin, Hyaluronic Acid (HA), & Anti oxidants. This supreme formulation brings a high impact joint supplement to the market, the effectiveness of which is vouched for by its outstanding customer feedback.

Where most other brands fall well short of an effective daily dose level, Complete HA offers uncompromised quality allowing horse owners to give their horse the best possible joint care.

Advancing age, as well as exercise, can lead to a breakdown in the natural regeneration process. Complete HA provides high levels of targeted ingredients, which nutritionally support the health of the joint structure, including the cartilage, ligaments, tendons, and bone cell regeneration.

This is the most effective joint supplement for horses in competition, with a heavy workload, or horses with reduced mobility and challenged joints. Riaflex Complete HA can also be used for maintenance on apparently healthy horses to prolong their happy, comfortable working life.

Despite the very high cost of Chondroitin, Riaflex Complete HA has been designed to provide a full 4g daily along with 10g Glucosamine and 10 g MSM when given at the Optimum rate for a 600kg horse. Be aware that many other commercially available products fall well short of these levels and include only token gesture amounts of Chondroitin that will hold little benefit for your horse.

Customer Testimonials

Thank you for your advice regarding my horses joint problems. He is now better than ever and I use Riaflex Complete RELIGIOUSLY.

I wanted to thank you personally for bringing such a wonderful product to the market, which I fundamentally believe has played a huge part in Jaspers recovery. I now have a happy, healthy horse again and I can't tell you how much that means to me.

Charlotte Pickering CompleteHA

I just want to tell you I have been using Riaflex on my 23 yr old Arab X for 3weeks after doing a lot of research relating to dosage and joint supplements on the market. I had him on one without the chondroitin, but he wasn't as free moving as he has been in the past. My research made me realise he wasn't actually getting the dosage he needed. I found Riaflex and decided to try it. Well I cannot believe the difference in him and keep having to pinch myself! I have been taking things easy bringing him back into work after 3 months off due to me injuring myself riding our youngster. But today he threw in his own collected canter and snorted as he took of as if to say "Come on Mum I can do more than trot!" I am so delighted and feel like Riaflex has taken years off him.  Riaflex is the best gift you can give to your horse and I am so happy I found it!

Maree Macrae CompleteHA

I just wanted to email and say how impressed I am with Riaflex Complete. I have had my mare on it for 23days at maximum dosage and she is like a different horse. She was diagnosed with quite bad OCD in both stifles and then later on suspected navicular. Soundness has been a long term issue for her and constant worry for me but we have hopefully turned a corner. Tonight she felt and looked like a different horse. 

Just wanted to share with you and Thank you.

Emma CompleteHA

It's been quite some time that I have been using your product Riaflex Complete HA. My horse Connor has struggled with arthritic changes in his hocks since he was 10 years old. About 3 years ago, I retired Connor from ridden work due to his increased stiffness. 

Since using Riaflex his joint flexibility has improved significantly, so much so that 5 months ago I started riding again! And two weeks ago we had our first riding lesson in many many years. 

I recently requested an independent nutritional report as Connor had lost condition. I had to document everything about him. The report concluded many things but significantly that Riaflex was a very good supplement and that I should continue to use it. 

I just wanted to thank you so much for your product and I have my horse back again. Something I didn't believe could happen. Many many thanks.

Louise Helsdown CompleteHA

Well physio thinks a miracle has happened. After being on holiday for 4 weeks she came out to Indy yesterday and just couldn't believe the difference in her. She has gone from being 7/10 lame to being able to trot a 20m circle soundly on both reins, and I now have permission to take her out walking. So thank you so so very much Kate. I was thinking I would have to retire her as the vets had advised and I was so upset at the thought of having to find another horse that I thought I'd give Riaflex ago. And here we are with my Indy back.

Gail Bateman CompleteHA

Started my 18 year old horse on Riaflex Complete for his arthritis and seeing amazing results - fantastic product he now thinks he is a 5 year old again!!

Paula Saunders-Spokes CompleteHA

Bruno developed a common joint problem at the age of 13 and despite extensive care he showed little improvement. So we decided to try Riaflex CompleteHA and the difference in him is significant. We are now hopeful that he can be given a couple more good years of the ridden work he so much enjoys, so thank you Kate.

Janet George CompleteHA

My horse of 20 years sadly suffered from a severe injury in 2006. After thinking I had tried everything thankfully, a friend recommended I give Riaflex Complete a go, and within 1 month she has astounded us all. You would never know she had such a severe injury, when watching her move. I put the wonderful condition my horse is in down to Kate, and want to thank her for giving me my horse back. Her advice was invaluable.

Jacqueline Ireland & Nellie CompleteHA

I just wanted to write and tell you what a difference Riaflex Complete has made to my mare 'Africa', who suffers with several very common joint problems in her hocks, and coffin joints.

I put the wonderful condition Africa is in now down to Kate and Riaflex Complete. It has made such a huge difference to her quality of life so Thank you so much Kate for your fantastic product and your excellent customer service.

Nichole Waller & Africa CompleteHA

I am just emailing to say that after 2 weeks on Riaflex Complete HA the difference in Fables hocks is amazing. He has gone back to his happy hyper self and is clearly more comfortable. I've been desperately trying to find a supplement that works, and finally I have.

Thank you for your advice. I have recommended you to everyone I know.

Mel CompleteHA

I have had my mare on Riaflex complete HA for 2 weeks now and have seen a remarkable improvment in her. She rides so freely now with no sign of soreness. My vet agrees that it is the best product she could be on. I just wanted to say thank you so much.
