    Hi Martina,

    What a great post and very informative. We just ‘inherited’ a horse (long story…). And we are researching a lot to provide this little one the best we can offer

    I was wondering at what age would you start giving joint supplements?

    Just like supplements for humans, there are different quality and brands. What brand do you use?

      Hi TerrbyB!

      Thanks for your comment and positive feedback 🙂 Awww thats good to hear! And it really depends on what you have planned for the horse? Do you think you’ll be showing him/her or working him/her heavily? And when?

      If your horse will be worked lightly or intermittently, you can either elect to not put your horse on a supplement, which is fine! If you want to be on the safe side, you probably want to start after a few years of riding. And start LIGHT – with a brand like Nutramax’s Cosequin (the original or maybe MSM supplemented).

      If you plan on working him/her more later on, then either upgrade the Cosequin or add an independent ASU just for preventative measures.

      If you know that your horse is going to be ridden a lot and is going to undergo significant wear and tear on his/her joints, I would start with the Cosequin Plus as soon as you start the intensive work. I like this brand because they are completely transparent with all their ingredients, and they show their research, which lots of companies don’t do.

      For some horses, their formulation simply isn’t potent enough, however, in which case you can try Cortaflex (buy the larger dose and split into quarters to save money) and/or get an independant Collagen II supplement.

      Collagen has by far had the best scientific results when administered orally, the issue is there aren’t many Collagen II supplements out there. I’ve found some used by bodybuilders and included in an equine formulation that I can’t find any proper research on so as you can imagine I’m not overly encouraged by the brand. Here are the links incase you are interested in looking: veggie-derived collagen, chicken-derived collagen and equine supplement with collagen in it

      I’ll try and get out a post on this soon and keep digging regarding the Collagen! Hope I was helpful though! Let me know if you have any other questions – cheers,

    Hi Martina,
    I really enjoyed this post on choosing horse joint supplements. I wonder if you have a recommendation for older horses? My quarter horse turned 29 this year. He has been part of the family for 23 years I so am very keen on keeping him comfortable 🙂 His overall health is very good and his lameness is not severe but he does have stiffness.

      Hi Linda,

      Thank you for your comment and positive feedback! That’s truly a great age, I’m sure you and your family are very attached and proud of him 🙂 Normally, at that age I would recommend a collagen supplement for sure but I’m still having trouble finding a really good one you can get online (if you look at my comment above you can see some of the ones I’ve found and they aren’t that reputable). Also since your horse only has some stiffness with good health, I don’t know if he’d even need it.

      So I would say, go with Cosequin – either the original or maybe MSM supplemented. Probably in your case the original should be just fine. It’s a relatively mild supplement, and the site is super transparent and shows all label info as well as straight up displays its research. Some horses don’t feel any effect off of it but I think in your case it should be just fine. Try the original and then if you are still noticing stiffness in about a month then up to the MSM supplemented. If you still see no improvement then e-mail me at martina@equestrianbootsandbridles.com and I’ll recommend something else for you 🙂

      I hope this helps! I’m coming out with a new post this week an some reviews since this is the second comment I’ve gotten requesting recommendations. So check it out if your interested!

    I forgot to ask if there is any supplement company which guarantees results for horses or are the chances the same as supplements for humans? As someone who has worked in a healthcare shop which sold health supplements I absolutely agree that its imperative that you check the effectiveness of the product

    • Martina

      Yup there definitely are! Acti-flex 4000 which I talk about here has a satisfaction guarantee on it, but Cosequin doesn’t. Although Cosequin does have plenty of research backing the results that it claims to produce.

      I totally agree! The best way I think is to get as much information as you can, make an informed choice based on both the supplement and your horse’s needs and if it works, great! If not, then move on to the next best product.

    Great post, thank you.
    I have just found out my boy has had had major trauma to his hindquarters. So the muscle stabilising his stifle is non existent. This means there could be cartilage damage to his stifle joint. He is only 6 years old. Can you recommend something that might help regenerate his cartilage if damage has been done.
    Thank you for your time.

    • Martina

      Hi Megan – I’m so sorry to hear that. That sounds really hard on both of you. Unfortunately, with that kind of damage I would really advise taking him to see a vet which I’m sure you have already. See what the vet says and if they can lay out a plan for you. The problem is supplements are just that – to supplement – and as great as they can be for preventing damage and maintaining joint integrity, they’re not as good for repairing large amounts of damage that has already taken place. Nonetheless, it doesn’t hurt to try so in your case I would recommend: Cosequin ASU Plus. You can read more about it here: https://equestrianbootsandbridles.com/best-horse-joint-supplement-reviews-what-to-buy/ under heavily trained horses. Also if you can ask your vet about a collagen supplement, then I would also use that.

      I really hope that helps!!!!
