You can't beat the price of this. Just recently started my gelding on this so can't speak to effectiveness as it is too soon to tell. However, if this works, for the price you just cant beat this. I mix this into his grain in the evening and he has no problem eating it.

For older horse.
Claire L on Mar 11, 2015
MSM works great w/older horses that have joint problems. We have used this for years to help our older horses as they get stiff & still have the heart to compete. One of our babies was hurting & we thought we might have to retire him, but now on MSM he is feeling great & runs into the barn for feed neighing, head up high, & letting us know he is feeling better.
TAMMY W on Jan 28, 2015
I started using MSM for my own joint issues. After much success for myself did some research and found that it was originally given to livestock. So I started giving it to my horses several years ago - and to date no lameness or stiff joint issues. Knock on wood. I have a 20 year old and 13 year old horse.

For people use?
A shopper on Feb 3, 2019
BEST ANSWER: Well, I've taken MSM by capsule from stores that sell it over the counter but never from the tub I buy for my horses. Don't think supplement standards for equines are as stringent as those for human consumption. But who really knows? I'd like to think its a good anti-inflammatory; my horses and dogs seem to benefit from it. Unfortunately I've developed an allergy to sulfa and can't take it anymore.
can this be used on cattle, sheep and goats?
graceelizabeth on Aug 18, 2018
Does this come in a larger size than 10 lbs.?does this come in a larger size than 10 lbs?
A shopper on Jun 26, 2018
BEST ANSWER: No, 10 lbs is the largest size sold.
does msm help with founder ?
A shopper on Aug 22, 2017
BEST ANSWER: That would be a question for your veterinarian. (I don't know the answer.)
is this a powder or a pellet?
A shopper on Apr 8, 2017
BEST ANSWER: It's a powder and my horse will eat it in her food just fine
Is this powder or crystals?
Bobby on Oct 26, 2016
BEST ANSWER: Crystals similar to salt only the 'crystals' are a little larger. I hope that helps.
Can this product be used for dogs also?
Katiw on Oct 9, 2016
BEST ANSWER: Yes, I give a pinch to my dog twice a day. If you look it up on line there is a recommended dose that is much less than the horse dose but I can't remember what it is.
Can I mix the MSM with the AniMed Glucosamine? I have a 21 year old barrel horses that I would like to supplement.
Sheena on Apr 18, 2016
BEST ANSWER: I would contact your veterinarian.
Is the MSM pellets or white powder?
A shopper on Nov 8, 2015
BEST ANSWER: This is white powder. Seems to help my animals a great deal.
Can I give my dog the MSM joint supplement ?
A shopper on Sep 23, 2015
BEST ANSWER: This item is intended to be used on equines only.
What is the shelf life of MSM?
A shopper on Jul 19, 2015
BEST ANSWER: Any supplement should last 6 months to a year when stored under the conditions recommended on the label.
Is MSM safe for human consumption?
A shopper on Apr 22, 2015
BEST ANSWER: MSM, in the proper form and level of cleanliness, is safe for human consumption. I take 1500 mg. of it daily, which I obtain from a well-known vitamin/supplement supplier. MSM is very popular in Europe as a pain reliever. Generally, the labeling of the horse-intended MSM states that it is for livestock only, so I have not ventured so far as to take it myself, but it sure seems to make a difference to my horses!
Do I just mix the powder with the pellets?
A shopper on Jan 17, 2015
BEST ANSWER: Yes, my Vet suggested I use it and I have been for many years. I love this product , its easy to use the price is great and my horses have no problem consuming it. I put it in a snack baggie with another supplement and it is placed on top of the grain at feeding time. Hope this helps you :)
How much would I feed a 2 yr old mini? She's about 250-300 lbs
Anatolian on Nov 26, 2014
BEST ANSWER: You would need to consult with your veterinarian before administering.
If I buy the 10lb will it lose it's potency by the time I finish using it?
A shopper on Nov 1, 2014
BEST ANSWER: MSM or methylsulfonylmethane, is an organic form of sulfur. The chemical formula of MSM is CH3SO2CH3. It is the form in which sulfur appears in nature in all living organisms, and in which it is biologically active. MSM is an odorless, white, crystalline powder that is highly soluble in hot water and in a wide range of organic solvents. As such, if you keep the lid on the container tightly closed between uses, it should last with full potency for at least a few years after it was properly factory packaged. You should avoid allowing moisture to contact it, and you should store it within a reasonable temperature range until it is being administered.
how long it takes to be shipped?
A shopper on Oct 7, 2014
BEST ANSWER: it depends on what shipping you choose. Economy shipping is 7-10 business days and Ground shipping is 2-6 business days and we also offer 2nd day and overnite.
