I only have one horse actively doing endurance, so he's the one that could
benefit from a little extra E. There's been some good research done on
wild-caught zebras and mustangs, where they were trying to solve a problem
of losing or injuring some animals due to the muscle exertion of being
captured. They discovered that when the animals were supplemented
beforehand with vitamin E (an extra 1000 IU per day), the losses and
injuries due to overexertion dropped dramatically. Vitamin E is a component
of the connective tissue membrane that surrounds the individual muscle cells
and alot of after-exercise muscle soreness is due to microscopic tearing of
this connective tissue, so apparently extra vitamin E helps supports this
tissue and minimize tearing.
E is a fat-soluble vitamin, so the body will store excess amounts. As long
as you don't go way overboard (more than 10,000 IU a day), which is
approaching possible toxic levels, it won't get peed out like the
water-soluble vitamins (like B and C), it'll provide an extra storage depot
for use as the body needs it.
Since I know this'll be the next question coming<g>, I *personally* feed
Cato about 2000 IU a day when he's working hard, mixed up in his beet pulp
mash. The most cost effective source I've found so far is through Valley
Vet Supply 1-800-356-1005, I get E-5000 from Vita Flex. A four lb bucket (a
five month supply) is $48.95.
Hope this helps?
