Rated 5 out of 5 by from FABULOUS SUPPLEMENT!!!! I purchased E-5000 on the recommendation of a friend to improve my horse's coat. No sooner did I start him on the product that I saw an immediate imorovement in the condition of his coat, mane and tail!

Rated 4 out of 5 by from E-5000 My trainer suggested vitamine E for my horse and I ordered the E-5000 a month ago. My Throughbred ate it the very first feeding and even licks his rubber bowl clean.

Rated 5 out of 5 by from Love this stuff! Started using this when my 22 year old gelding developed EPM. It really helped his immune system and is great for preventative maintenance.

Rated 5 out of 5 by from Helped my gelding turn the corner We were having trouble getting muscle on my older TB in spite of all the right training practices and vet care, so my vet suggested a high dose of E since our area's hay in low in it. We noticed a difference in his topline a month later, and three months into the supplement, he looks great and is feeling much stronger.

Rated 4 out of 5 by from vitamin treatment I've been treating my gelding for EPM which sparked my interest in the E5000. I had no trouble at all with him eating it all with his regular grain and other supplements. He's also still on the second month of Marquis treatments. I don't know which factor to praise but his is making a wonderful recovery and I plan to continue the E5000.

Rated 4 out of 5 by from horses gobble it up I have only purchased this brand so have nothing to compare it to. Both horses eat it readily without having to hide it in anything.

Rated 5 out of 5 by from proven to work My horse's lab work came back indicating his vit E levels were more than adequate after 3 months on this product. The horse is 1400# and only 1 scoop aily.

Rated 5 out of 5 by from immune function booster I've had my new horse on this product for six months. He was underweight and didn't have a great appetite when I bought him. There is no doubt in my mind that he rebounded so quickly due to this product. After the first month he was eating better. After the second month he his endurance was noticeably better. It just keeps getting better.

Rated 5 out of 5 by from A great benefit to horses with EPM I have a 6 year old mare, diagnosed in the spring with EPM. I ordered the E-5000, along with some other supportive supplements, and put her on them for one month, along with her prescription treatment. She not only gained weight, muscle tone, and strength, but she didn't suffer any of the side effects of the drugs. Months later, she is holding her own and maintaining her condition. I haven't started working her again, but I will likely put her back on this combination for the winter, and restart her training next spring, once we're sure the EPM has been eliminated. The E-5000 is crucial for any horse with a compromised neurological system, as is the case with EPM horses. A must have and worth every penny!!!

Rated 5 out of 5 by from Best Vit.E It is good to know that my horse that is deficient in Vit E is getting the right amount everyday and his level is where it should be. It was really hard to find a source that was high enough in Vit E to do the job but this is it!
Date published: 2010-08-11
Rated 5 out of 5 by from good for intensely trained horses When I was preparing my mare for world level competition, I had her on the full dose of E-5000 and I saw an increase in her attitude, physical appearance, and recovery time. Now she is on a slightly lesser dose since she is basically retired.

Rated 5 out of 5 by from WOW! Started two weeks before Memorial Weekend. I was out of town for four days - when I returned I didnot recognize my horse! His winter coat was completely gone, he was his big beautiful sorrel shiny self again, and the most miraculous part is his muscle tone and topline inproved tremendously. I can see the difference!!!

Rated 5 out of 5 by from feel good product I believe in this product for helping my horse recover from everyday wear and tear. I have great comfort that they have this product to keep them healthy everyday.

Rated 5 out of 5 by from Effective and Critical I have been using Vitaflex E-5000 on my horse for two years now and he has significantly improved in his general health. It is pricey -- it's only drawback -- but because my horse is in "moderate" work and not a high-powered eventer or showing regularly, I find 2500IU keeps him fit and energized and his muscle recovery from work is excellent. He's 24 and still performing at 3rd level dressage.

Rated 5 out of 5 by from A miracle for Lucky I just want to share my experience using this product. For two years after a serious illness, I had been trying to put weight back on my 25 yr. old gelding (he looked so bad well-meaning folks were constantly calling the authorities about him!). After trying everything (worming, antibiotics, different feeds, supplements, etc. etc. etc.), as a last ditch effort my vet recommended feeding him 5000 IU's of Vitamin E per day. After only six and a half wks he has gained almost 100lbs., and is very frisky. I'll be able to ride him when he gains a little more weight and as soon as he builds some muscle tone...This stuff rocks and it is very affordable!
