HorseTech's Selen AT combines premium quality Selenium Yeast and Natural Vitamin E in a convenient, concentrated and palatable supplement! Each 1/2 ounce serving of Selen AT will provide one (1) mg of selenium and a full 1,250 IU of Natural Vitamin E. The smaller, more compact, serving makes it easy to handle/feed and is cost effective.

Selen AT features two palatable and nutritional base materials --flax and yeast culture. Our northern-grown, premium-grade flax is actually made for use in bakeries--it's intended for human consumption. Our other base material, yeast culture, is made right here in Iowa as well by the company that all but invented yeast culture--Diamond V Mills. We've done business with them for nearly 30 years, and we know them to be reputable suppliers of premium quality ingredients. 

As always we've backed it up with our standard 100% satisfaction guarantee! Try our Selen AT today. I'm confident that it is the best Vit. E/Se product on the market today, and I guarantee that you'll be delighted with the results. Thank you for giving Selen AT at try!

best natural vit. E and selenium supplement
I live on small acreage, so my horses don't get to go out on grass 24/7. On top of that, the soil in my region is also slightly deficient in selenium. Selen AT is the best quality and priced product I've found to supplement my guys with the natural vit.E and selenium they're missing from their diet. They will be on this product indefinitely. Thanks, HorseTech! Review by Fienix / (Posted on 10/14/2015)
