Awesome product
As the owner of a equine therapeutic business I look for products with whole ingredients! Less is more! The purity/simplicity of ingredients caught my eye. I usually mix all my own herbal supplements, but I was looking for something quick and in liquid form. After research, I purchased this product; fed recommended loading dose to my 16 yr old barrel horse whom I noticed was moving stiffer. After being on this product for over 3 weeks she is moving like she's 6 again! I've never been impressed enough by a product to write a review but this def deserves one! High 5!!!!

Awesome for the price
Started looking for a cheaper joint supplement alternative for my 15 year old barrel horse and came across this. Worked wonders and didn't break the bank! My picky eater licks the bucket clean and is bucking and playing like he did when he was younger. I haven't heard any popping in his joints since I started feeding this.

I give it to my two older horses daily
I have been giving this product to my two older horses for about 8 months. They seem to get around much better and with the cold winter we had this year i think that is saying a lot. I will continue giving horses are 24 and 17.

great taste. my horses love it
I've only been using this product for a couple of weeks but I've noticed that my horses seem to be getting around better. They both were having trouble with walking. One had been injured as a four year old and one is 23 and has feet problems. They love the taste and seem to be doing good on it

Great Product With Good Results
I bought this for my gelding after it being recommend by someone else for its results and price. The larger jug does not come with a measuring cup however so I used a syringe. After a week or two of the fluid kicking in I got a noticeable result. My arab in normally stiff with his right hock at the beginning of rides and during grooming. He was not slow or stiff and seemed more comfortable and peppy over all. He is also a picky horse and didn't mind the cherry flavored liquid.

Is this product safe for a pregnant mare / foal?
A shopper on Jan 21, 2017
BEST ANSWER: I don't feel qualified to answer that, but in my opinion I would probably not give it to a pregnant mare. Your best solution to this question would be to ask your vet. Otherwise, I love the product for my 17 yr old gelding!
