Best Value
MSM is the best oral supplement for joints. I have been feeding Select The Best MSM for a few years now and it's a staple supplement for all my horses (prevention and maintenance). The 20lb bucket offered from Smartpak is a SUPER deal! It's like buying a years worth for all three horses. Will continue to buy and recommend!

Effective Supplement
I have been using this supplement for several years, but was excited to see that it was on SmartPak, and for a much better value than our local feed store!

Not sourced in the USA?
I was buying this at the feed store for a lot more money so I switched. I can't say it is working any better or worse than what my horse was on but I do use it myself (NOW brand) and believe it is very good for us. The only reason I took off two stars is that the manufacturer is being secretive as to where the MSM is sourced which in my mind is a bunch of bologna. If they are hiding the sources, then logic tells me it is probably from China or worse. I will not be buying this brand when my bucket runs out!

Happy Horse! Great for Digestion
She is now 17 and in the best health she has ever been in. Got rid of the fancy stuff and started giving her this with a simple basic supplement. Add in some Omega Shine, and She Looks Amazing. She really is the healthiest, strongest, shines like a black diamond (and she is out in the hot sun by choice). She is happy and healthy. I will never be without this product, and she loves it. Now the whole family is using MSM now. My German Shepherd no longer has hip problems, yes, this supplement is that important. And My husband got his Hearing Back! Yes, true story! Highly recommended.

Select the Best EXTREMELY RUDE AND DEFENSIVE!!
I called Select the Best customer service to simply inquire where the M S M is manufactured. The lady that answered was very defensive and very rude, stated that they don't give that information. I asked to speak to someone else, and the "head" of customer service was extremely rude and defensive also. He answered that it is made in the US, so I said that it is helpful if that is printed on the label. I also informed him that the lady was extremely rude and defensive and he was very rude and defensive about her. THIS LEADS ME TO BELIEVE THAT MAYBE THEY ARE NOT TELLING THE TRUTH! A product that is made in the USA would be a positive feature to brag to customers. I DO NOT want to buy any of their products anymore, based on the way I was treated. I asked a simple question in a kind manner, all I needed was a simple answer. Kind of ruins your morning to be treated like @#%* and have already supported that company. Good customer service DOES MATTER!

Great for Mane and Tail growth
We started feeding this to the barn (14 horses) a year ago for joint health-- not sure that it works for that but it is amazing for mane and tail growth. Horses that had thin manes and tails have really gotten so much thicker.

Helps with arthritic joints
Added this to my 26 year old regimen over a month ago. He seems a little less stiff and has more 'go's in the ring.

Great Price on a Good Joint Supplement
I have a 14 year old horse who has a club foot and I have given him MSM for many years as a preventative. I had to have x-rays on his club foot recently due to some hoof issues, and the vet said there were no signs of arthritis, so it appears to be doing it's job. You can't beat the price on this product, and both of my picky eaters eat it with no problem. I have used other brands of MSM in the past but switched to this one to save money.

Not Sure
I started using this two months ago without realizing other supplements would be needed to make this one most absorbed / effective. Thankfully I was using this primarily for respiratory functions and inflammation, and not joints. I have decided not to continue this and get a combo pellet as it is more affordable than everything individually.

Great price and for hocks
Got for my horse with a bad hock that would swell. Tried other joint supplements that helped some but once I switched to this the swelling went down and has stayed down. Also use with Majesty's FlexHA. Neither help with her ringtone however that she's had for almost 15 years. I also give the MSM to my other two horses. Also like there's no fillers.

Great product for the price
I bought the four hundred and something day supply bucket for my four horses and I have nothing but good things to say about this product. It’s good quality msm at a bargain price, especially when bought in bulk as I did. 100% recommend.

Great product, great price
I've used this for many years on multiple horses and can definitely tell a difference when they're on MSM. I highly recommend esp when you don't want to spend an arm and a leg for a similar product.
I don't consider my horse to be a picky eater, he east most things.

Excellent product
I give this to all of my horses. I like that it has no fillers, and my horses find it more palatable than other brands. When I stopped using it for 2 months, my farrier noticed less fluidity in my horses' movement, so they are on it permanently.

MSM
My Mare is recovering from EPM and I want to keep her on a anti-inflammatory. As I am on Soc. Sec. I cannot afford a big price. This MSM is pure and very economical for me. I believe it works just as well as a higher priced MSM product and the bucket lasts a few months. Thank you Smart Pac for providing this high quality low priced product.

As Expected!
I bought this for my mare who has been shown all her life and had a severe injury to a hind leg. It works to keep her comfortable and able to move. Only drawback is the bag is a bit difficult to use as the opening is not very large for a person with larger hands plus the scoop.

Affordable Joint Care!
I have been using this supplement for about one year. I have a 16 year old Appaloosa gelding who was a rescue. I have decided to use him for barrel racing, and I wanted to give him something basic to keep his joints healthy. Overall, he is a very healthy horse, so I did not feel that I needed to put him on an extensive joint supplement--just something basic to help him ease into work and keep any swelling or discomfort away. He has done very well on this! Sometimes he does not eat all of the powder, but it eventually gets cleaned up in his feed tub. Pellets would be nice, but I do like how economical this particular supplement is. I couldn't be happier with the results!

Noticeable Results
I started my older, retired endurance horses on this at my vets suggestion. I saw noticeable improvement in their comfort levels and the elasticity of their gaits after the first week on the recommended doseage. Even my farrier commented on how much better they felt to him in terms of their flexibility as he worked on them. I was sold! This is a great product at a great price!!!
