Hi Kim,
Yes, you are right -- if your horse is getting more than 8 hours of pasture grazing each day, and the pasture is healthy (not overgrazed or stressed), you can either adjust the Glanzen Lite Complete down to 1 scoop per day. Or, if you like to have the additional hoof support and extra B vitamins, switch to original Glanzen Lite at the 2 scoop/day level.
If your horse is exercised regularly, in training, or performing, I recommend increasing the vitamin E level beyond what pasture can provide. There are 1250 IU of vitamin E in one scoop of Glanzen Lite Complete and only 150 IU of vitamin E in one scoop of Glanzen Lite.
It is best to provide approximately 2-5 IU of vitamin E per lb of body weight, depending on the exercise level.
All the best,
Dr. Getty
