I was considering ordering vitamin E from Amazon.  Any recommendations on what to get? 

Thank you!

Human or Equine form?

horse

Can't recommend any equine form from Amazon. Be sure to get one that is in a natural form as it is easier for the horse to asborb. 

I think this one is about the best out there, Elevate.

Health E from Equine Medical & Surgical Associates. Not sure if they sell it on Amazon, but you can order right off their site. I've ordered several of their products and they are all fantastic.

Elevate is the best brand of vitamin E. And I have found it on amazon even though you are supposed to have to get it through a vet. if you are getting the powder form make sure you get the Concentrate and not the like maintenance or whatever you can get OTC because the maintenance is not as strong and you need to use more of it. 

I ge my Vitamine E from The Equine Edge.

I would recommend ordering from Valley vet. I have ordered horse minerals from Smazon and they were far from fresh. I use Elevate

As others have said, Elevate is the best. It's made by Kentucky Performance Products, and you can order right through them- you don't need a prescription.

The only difference between the Elevate and Elevate concentrate is the scoop size, the Reg. Elevate scoop is tiny and the concentrates scoop is huge compare to the reg. Elevates. Its cheaper to buy the reg. Elevate in the larger size and just double up the dosage if needing to increase the IU. Thats what I have done in the pass. I bought both of the Elevates/concentrate and was suprised that the only difference was the scoop size.

Equine Omega Vitamin E.  Natural not synthetic.  10,000 IU a day
