I keep hearing if MSM and selenium are fed in the same feeding, the MSM will block absorption of the selenium.
Is there any truth to this?

Leah,
I went to valleyvet.com and placed msm & selenium under the search area. Twelve products appeared listing the two ingredients together along with other products. You could e-mail valleyvet or the listed manufactor and directly ask about the malabsorption.
Good Luck Hope this helps.

The interaction between fed MSM and selenium in horses (or any other specie) has not been studied. Nor is it likely to be studied since there are no known nutritional or medical benefits to feeding MSM other than as a very expensive source of sulfur, a mineral that is not usually a problem in the horses diet.
Most believe the MSM is largely broken down to sulfur in the digestive tract. We do know that high dietary sulfur levels do interfere with the bioavailablity of ingested selenium in ruminants. However ruminant digestion is very different than equine nutrition so I do not know if you can generalize this to the horse. As prevalent an addition that MSM is to the diet of horses, if it completely blocked selenium we should be seeing health problems associated with its use which we don't. On the other hand, perhaps the reason for adding selenium to the MSM is to make up for a real or perceived problem.
Assuming there is no special interaction with the MSM and considering the high tolerance for sulfur above what is likely to be in a horses diet, it is unlikely you will feed enough to block selenium uptake.
