Supports healthy immune & muscle function

  • Together, vitamin E & selenium support the immune system & help neutralize damaging free radicals
  • Provides 1,250 IUs of vitamin E & 0.625 mg of selenium per serving
Vitamin E and Selenium are important antioxidants that work together to support a healthy immune system and help neutralize free radicals, the damaging by-products of normal cellular activity. While vitamin E is found naturally in fresh grass, levels begin to drop the moment grass is cut for hay. In addition, many soils are deficient in selenium, making it hard to reach the recommended daily requirement of this mineral without supplementation. Vitamin E & Selenium Pellets by SmartPak provide your horse with critical antioxidant support in a tasty pellet your horse is sure to love!

    Vitamin E & Selenium Pellets by SmartPak is rated 4.8 out of 5 by 85.
    Rated 5 out of 5 by from Vitamins are essential Tremendous results in energy, coat, and weight. It's amazing how some hay can be so deficient in vitamins.
    Date published: 2016-11-05
    Rated 5 out of 5 by from Just what I was looking for. This product is just what I was looking for our two mini donkeys. Their blood work came back a little funky and the vet suggested this supplement for them. The pelleted form also makes it easy to add to a little bit of grain and they eat it without a problem.

    Rated 5 out of 5 by from Filly feeling frisky I had muscle soreness in a filly since Spring, the vet gave suggestions, the chiropractor did, then a read an article on Selenium that fit the problem. It is hard to find the products I need locally that are give the BEST RESULTS. Well she had been on this product 1month and is already feeling better. She is a picky eater but she cleans this right up!

    Rated 5 out of 5 by from Vitamin E & Selenium pellets I have been using this product for about 2 months and have seen awesome results. Skin is looking shiny and healthy. Weight gain and muscle tone on my 27 year old mare has improved tremendously. I am a very happy horse owner.

    Rated 4 out of 5 by from Works well I bought this for my OTTB that has shivers in two months I've seen a difference in his mobility however I found a similar product cheaper and without shipping.

    Rated 5 out of 5 by from Works Great Our equine chiropractor recommended this to help our mare with muscle soreness and after two months it seems to be working. Best of all the pellets make it easy to feed and she has never turned it down even though she's picky! Love the smartpaks!
    Date published: 2016-06-16
    Rated 5 out of 5 by from Excellent product. Vet recommended. Bought it a month ago ands I happy I did! My horse has never looked better.

    Rated 5 out of 5 by from Perfect for EPSM/PSSM Management A few months ago, my draft gelding was diagnosed with EPSM/PSSM. It was highly recommended that I add Vitamin E and Selenium to his diet. The Smartpaks have made this seamless with the host of other feeding changes that I've had to make for him - it's hard to forget!
    Date published: 2016-03-22
    Rated 5 out of 5 by from Works great My 14yr old quarter horse was diagnosed with PSSM. He was tying up in his muscles constantly. This product is easy to give and my horse has had no episodes since the day he started it. He has been on it for about 5 months.

    Rated 5 out of 5 by from Vitamin E & Selenium This product is awesome! My vet recommended Vitamin E and Selenium for my horse. I tried powders but she did not go for that! This pellet is wonderful and tasty to her and she eats it right up.

    Rated 5 out of 5 by from Helped my horse come back from lyme disease During her second month of antibiotics for lyme disease, I added selenium/e supplement and safe choice senior feed to my horse's diet. My horse appears to be bouncing back from lyme disease finally, generally happier demeanor, more energy, less fussy under saddle. We had good success with using this supplement on an older horse with chronic lyme at the horse rescue as well. I would recommend it. It's very easy for the horse to eat this because it mixes in with the pellet safe choice or other feed.

    Rated 4 out of 5 by from Good Product I bought Vitamin E & Selenium and DMG at the same time 40 days ago, so it is hard to tell which one helped most. I think every horse in training or competition should have Vitamin E & Selenium in their diets. My horse (8 yr old TB gelding), is now much more willing to do lateral work and stays level at the canter though the corners. I am very happy with both products so far.
    Date published: 2015-03-31
    Rated 5 out of 5 by from My horse is a very picky eater so I was worried she would go off her feed.. But she loves it and I am glad I don't have to syringe her another supplement

    Rated 5 out of 5 by from Very palatable! I started Joe on this 2 months ago and his overall appearance has come so far!!
    Date published: 2015-02-20
    Rated 5 out of 5 by from great product! I bought this for the extra antioxidants for my PSSM horse. Hes a picky eater and eats this right up. He seems to feel and look great.
    Date published: 2014-12-31
    Rated 5 out of 5 by from Nice product! I started my horse on this recently, as he needs a vitamin E supplement in the winter and I live in a Selenium deficient area. He will eat almost anything as long as it's pelleted, so no problems there.
    Date published: 2014-12-27
    Rated 5 out of 5 by from Excellent combo I love this combination, and the dosing. I don't worry about over supplementation in my program. No issues with my mare eating it. Love that it's pelleted and not messy - I can be sure she's getting the full dose each time.
    Date published: 2014-12-06
    Rated 5 out of 5 by from Smells terrific - just like tangerines This stuff is terrific. My horse needs this supplement as we have had our hay and forage tested and this is convenient. Plus every horse in the barn just gobbles it right up, even the picky eaters.
    Date published: 2014-12-03
    Rated 5 out of 5 by from EPM horse in recovery I bought this to help with the recovery of my horse with EPM. He never leaves it in his bucket and in just one month I'm already seeing improved motor skills in his hind end. He'll stay on this forever now

    Date published: 2014-10-30
    Rated 5 out of 5 by from Great combination Very happy with this product. I was told by an equine practitioner that the heat of summer can cause chronic dehydration amongst working horses and this combination is a good choice to help combat that problem, along with the known benefits of Vit E and Selenium.

    Rated 5 out of 5 by from SELENIUM/VIT E Great supplement for a horse that does not get enough grazing time.
    Date published: 2014-09-02
    Rated 5 out of 5 by from Amazing Protection! I bought this for my gelding who has a weak immune system and is prone to viruses and disease. After a week of feeding it practically protects him from viruses that come and go at the barn! He's a picky eater, and loves the taste. Truly fantastic protection!
    Date published: 2014-08-26
    Rated 5 out of 5 by from needed product I believe all of our horses in New England need Vitamin E and Selenium supplementation to the fact that our hay really doesn't have it due to poor soil conditions. My horses looks fantastic after one month on it. She is so shiny and soft.
    Date published: 2014-06-12
    Rated 3 out of 5 by from This is not natural Vitamin E I have decided per my Vets suggestion to find a natural E for my horse and an organic selenium. There is a product I wish Smartpak would carry that has both. Crazy thing is, Smartpak has a natural E but it doesn't include the organic selenium. The most bioavailable form is water dispersable liquid alpha-tocopherol formulations and Smartpaks natural E is the next best form according to my Vet. So, it is going to be a hassle but I reluctantly will be buying the E and selenium elsewhere for now.
    Date published: 2014-06-06
    Rated 5 out of 5 by from Great supplement! Great quality!! Great price!! Need it for a horse that is vitamin E deficient
    Date published: 2014-05-15
    Rated 4 out of 5 by from Good maintenence supplement This is a nice maintenence supplement for horses who do not necessarily have any noted deficiency. I use it because in winter the forage has little vitamin E. It's not the kind of supplement where you notice a huge 'change' in your horse, but still very important to his overall health.
