Natural Vitamin E Supplement for Horses, Powder - 4 horses at San Juan Ranch

UltraCruz Equine Natural Vitamin E® Supplement for Horses provides a natural antioxidant and immune support for horses. Vitamin E aids in maintaining healthy concentrations of other important elements such as iron, calcium and potassium. Equine Natural Vitamin E Supplement works in conjunction with selenium and vitamin C to promote normal immune system activity and protect the body from oxidative stress during exercise and performance. This high quality Vitamin E supplement is provided as a palatable powder for easy feeding and affordability.

Horses do not naturally synthesize vitamin E therefore UltraCruz Equine Natural Vitamin E® Supplement for Horses is an excellent source of this essential vitamin and is highly recommended for overall health of the horse. Vitamin E is a fat-soluble vitamin that functions as a powerful antioxidant. It is often used to help performance horses that experience soreness, as well as horses that require antioxidant support and to help prevent tying-up. Vitamin E helps eliminate free radicals and reduce oxidative damage to tissues. Vitamin E supplement for horse is also important for proper nerve and muscle function along with the immune system benefits.


Vitamin E generally is supplied through green forage in fresh green pastures, but that isn’t always an option for most owners. Vitamin E levels begin to diminish once pasture is cut for hay, and little is added to most concentrate feeds. Storage of the feed and hay can further destroy some of the Vitamin E content making it easy for deficiency to take place. Adding a high quality Vitamin E supplement such as UltraCruz Equine Natural Vitamin E® to your horse's diet can help support your horse against the damages of oxidative stress, which can be caused by free radicals.

What is a free radical?

Free radicals are highly reactive chemicals with the potential to cause damage to cells. Free radicals can be produced by the body during times of heavy exercise. UltraCruz® Antioxidant supplements contain powerful antioxidants to regulate free radicals and help prevent cell damage which can be caused by oxidative stress.

What is an antioxidant?

Antioxidants such as Vitamin C, Vitamin E and Selenium are substances that neutralize free radicals to help support healthy tissues and organs on a cellular level. Antioxidant support is recommended for horses subject to rigorous exercise and may help to reduce the negative effects of oxidative stress.

For a supplement packed with a comprehensive antioxidant formula, try our UltraCruz® Equine Antioxidant Supplement for Horses.

I see that 7 years ago someone asked what the vitamin E was sourced from. Has this formula had an update or is it still sourced from soy? Thanks

Asked by: 007mom
This product is still sourced from soy. Thank you, SCAH Team

Rated 5 out of 5 by from A must-have for my horseAlthough I initially got this product for other reasons where there might not be a noticeable-to-my-eye difference -- such as general health as they are not on pasture, one major result is that this product helps prevent my one horse's eyes from running. Prior to receiving UltraCruz Equine Natural Vitamin E, her eyes teared a lot, daily. On the occasion that I do not order more in time and I run out, they begin to tear again, but a day or two after she begins receiving the UltraCruz Equine Natural Vitamin E, they stop -- and do not tear at all. I have slacked off enough on reordering this in a timely manner to know that it is absolutely this product that stops the tearing.

Rated 5 out of 5 by from Great Product!!I tried this because the price was reasonable compared to some other vitamin E supplements out there. I do see improvement in my broodmare. My vet has also recommended this to other patients that need Vitamin E. The product is good, the price is reasonable and the shipping is super fast. My only suggestion would be to offer a size in a refillable tub. The bags waste product and are messy.

Rated 5 out of 5 by from Great supplement!My vet recommended I put my riding horses on vit. e. The barn owner recommended this supplement. So glad she did! It is much more economical then a lot of the other vit. E supplements. My incredibly picky eater will eat it not problem. Definitely felt like both my riding horses were more comfortable and happy to work after starting this supplement. I put my yearly warmblood on it a few months ago and she got very shinny and started filling out much better.

Rated 5 out of 5 by from FantasticFantastic product at a good price point. I'm very impressed with the natural source vitamin E. I can tell a difference, especially in my horse's coat and musculature. I always get comments on how shiny my 3 year olds coat is. When I had my quarab gelding, he was also on it and the vitamin E seemed to make his dapples more distinct.

Rated 1 out of 5 by from Blood test proves it's not workingI've been using this supplement with all our rescue horses for almost a year now. One horse we tested about 6 months ago when we got her and have since been giving her 2-3 scoops per day with her food, her blood test now shows no difference in vitamin E levels. We tested more horses and they all came back deficient. I'm extremely frustrated and disappointed. I've been using this supplement for all our rescues at high cost and it's like I've just been feeding them expensive air. I'm so disappointed at how much money our non-profit lost through this.

Rated 5 out of 5 by from Great Price and My PIcky Mare Loves ItI got this as a gift to try for my 32 year old mare nicknamed Ms. Picky. Because she's a senior, I supplement her with vitamin E year round. The other stuff I was using is pretty pricey and she's not a huge fan. My daughter bought this for me to try and see if she'd eat it better. She devours it in her feed. It's affordable, has great levels of vitamin E and it's natural vitamin E which is surprisingly hard to find! So glad I have a good option-and so is Ms. Picky!

Rated 5 out of 5 by from Mustangs Need and Love This ProductOur daughter is doing the Teens and Oregon Mustangs Challenge this year. Her 7-year-old South Steens mustang has recently discovered that she can eat more than hay :) We just started adding Ultracruz Vitamin E powder to her Triple Crown Balancer, and she loves it. We have already been using this product on our other 7-year-old Devil's Garden mustang because she has had issues with low vitamin E levels since we first got her 3 years ago. This product is a game changer for all horses, since it's very difficult for them to get enough vitamin E on their own. Our daughter will continue to use this product on her challenge mustang and we'll make sure whoever wins the bid on her at the auction knows what a difference the product has made in her life.
