“My horse has possible PSSM. He is a 1300lb Gypsy Vanner and his vitamin E & Se levels are low. I’m considering your product and the Vit E level in it is perfect but I’m concerned that the 3mg is too much ( my vet has recommended 1mg). My horses lab results are as follows: VitaminE serum = 1.98, Ref range 2.00-4.00 units ug/ml, Selenium Serum = 109, Ref range 120-180 units ng/ml. Any thoughts?”
Answer by Ph.D. Equine Nutritionist, Dr. Kelsey Johnson Nonella:
I am sorry to hear about your Gypsy Vanner. Selenium and vitamin E serve as antioxidants to aid the body in removing harmful free radicals from the body caused by oxidative stress. Signs of selenium and vitamin E deficiency can include muscle cramping and stiffness, much like PSSM.
I think that 3 mg of organic selenium will benefit your horse greatly. I did my doctoral research on selenium in horses. Horses supplemented with 3 mg of organic selenium have been showed to have increased immunity and combat oxidative stress more effectively than horses supplemented with 1
mg of selenium.
If you are interested in reading an article on my research here is a link to the article https://www.horseguard.com/innovative-selenium-research/
Increasing your horse’s selenium and vitamin E levels will help him to handle his PSSM better. I would also recommend feeding no grain, and only grass hay. If he needs extra energy, feed him something low in starch and high in fat, such as soybean meal or beet pulp.
I hope this help and good luck. Feel free to ask anymore questions that you may have.
