Product Overview

Revolutionary source of natural vitamin E

Nano-E® is a powerful water-soluble liquid vitamin E supplement for horses. Vitamin E is an essential component of your horse’s body-wide antioxidant defenses, and it plays a vital role in immune, cardiovascular, circulatory, neuromuscular, and reproductive functions. Nano-E was formulated using advanced nanotechnology that creates a rapidly available and absorbed source of vitamin E. Because it is rapidly available, administration can be timed to provide peak antioxidant protection to performance horses. 
  • Provides rapidly bioavailable natural vitamin E in an easy-to-use liquid form
  • Helps neutralize damaging free radicals and supports immune system health

Rated 5 out of 5 by from Happy Customer Started my 11 Year Old Mare on Nano-E and she’s less muscle sore. Comes with an easy to use dispenser.

Rated 5 out of 5 by from Fantastic Absorption I top-dress my Thoroughbred mare’s feed with Nano-E & she gobbles her food right up! Her Vitamin E had been low since I got her (And her Selenium high, so I have to give her pure Vitamin E with no additives.) I had her levels re-tested about 3/4 of the way through my first bottle. I had given her some loading doses of 6ml twice a day & then backed down to 2ml twice a day. Her current Vitamin E level came back HIGH! I’m just starting her second bottle & I’m now giving her 1ml twice a day. She will be rechecked in 6 months & annually thereafter. She will be staying on Nano-E indefinitely!

Rated 4 out of 5 by from Mm mm good! Ebony Chance loves the taste of his Nano-E so it goes down easily, unlike the steroids he's on which I inject into watermelon to get down him!!! There is no way I can squirt the steroid medication down his throat!!! It ends up all over me instead!!

Rated 5 out of 5 by from Effective Vitamin E I was starting to notice a rapid decline in my mare's muscle tone. We knew that she had Cushings and thought that was what was taking a toll on her muscles. We had her blood drawn and found out that she was also borderline deficient in Vitamin E and my vet recommended putting her on a natural Vitamin E supplement as soon as possible. I wanted to get something that I knew was effective and would work quickly. After doing some research, I found that Nano E was exactly what I was looking for and I was very impressed with their research on the product and their nanotechnology to make it absorb quickly. After three months on the product we noticed so much improvement in her muscle tone, and when we had her levels re-tested they were exactly where they should have been. This product is easy to use and despite my mare being a picky eater, she had no issue eating it when top-dressed on her grain. The bottle comes with a syringe and a syringe applicator and is very easy to use with no mess.

Rated 5 out of 5 by from Amazing Results! It was highly recommended that my horse be put on a vitamin E supplement as he is very laid back and almost too lethargic for a young horse. Using Nano-E®, my horse's lack of energy improved within a week or two! We are just starting our third bottle and will retest his levels soon, but, there is no question that this product has made a huge difference. It was suggested to use the Nano-E year round, as in the summertime he really needs it to help maintain a healthy immune system and supports normal nerve and muscle function. In the New England winters, it was recommended to continue as a vitamin E supplement because of limited access to pasture. I love that it is a natural vitamin E product and is a powerful water-soluble liquid. The results have been amazing!

Rated 5 out of 5 by from Seems to be very helpful My Vet recommended this to help my 35yo TennWalker. He has had Penile cancer for more than 15 years and looks like he did at 20. She said human cancer patients use vitamin E to assist their treatments. He does seem to have a little extra lift in his step.

Rated 5 out of 5 by from Excellent quality, needs dispenser top! Love this product. Ordered from smartpac and found, for the first time, no dispenser top for measuring by ml. Major inconvenience. All locally sold here in Virginia have the narrow opening and come with a syringe.

Rated 5 out of 5 by from Saved my severely E-deficient horse Purchased at the advice of my vet. Saw results within days. Will keep him on this supplement the rest of his life.
