### ⭐⭐⭐⭐⭐ Works with sheep also

### ⭐⭐⭐⭐⭐ Great product
*by C***E on November 1, 2024*

Great product. My horses are feeling much better now they are getting that little extra selenium.

### ⭐⭐⭐⭐⭐ cheap selenium powder. I appreciate it
*by A***N on March 15, 2025*

I bought some off of ebay, when they had the bucket, before Covid inflated the price of things. works great! but I didnt use it for a horse, I used it for myself, just wanted it cheaper than pressed capsules thats all. with all the toxins from covid, I took like multiple full horse doses in a day, maybe where I'm at is ridiculously toxic? I know that when I took too much I would get chest pain, because Selenium is apparently an oxygen moderator, as describbed by Dr Richard Olree ("minerals for the genetic code" by charles walters [also available on amazon]). for you folks who's horses dont like the taste of the yeast "tastes and smells like powdered farts" at times, but you can do brazil nuts too, those are SUPER HIGH in selenium too, and like mentioned above you can over do it too, and get chest pain in you eat too much, not sure how you would find that out on a horse though if it took too much, unless you have an ekg machine right there. selenium is the body's master detox mineral, but will apparently use tellurium from garlic too, though I heard garlic will disbalance the brains frequencies, and I suspect it may have to do with using a secondary mineral (tellurium) in stead of a primary-preferred mineral for things
