Hi, I am going to order Glanzen Complete for my 2 5yr. olds that are currently thriving on Glanzen 3. How does one know whether there is a need for the one with or without Selenium. We are on the Central Coast of California. I never hear any talk of need for Selenium from vet or fellow owners. Thanks

Hi 10 Walker,

That is an excellent question. The only way to truly know the selenium content in your pasture and/or hay is to have it tested. You can easily do this through Equi-Analytical Labs -- www.equi-analytical.com or your local county extension service may offer selenium analyses but check with them before submitting a sample.

California is typically low in selenium, however, so it is best to get Glanzen Complete that normally contains 1 mg of selenium.

If, however, you are feeding any other supplements or feeds that contain selenium, evaluate the content. For example, most commercial feeds have about .6 ppm of selenium. If you were to feed 4 lbs per day, for example, that would provide 1.09 mg of selenium ( [4 X 454 X .6]/1000). And, then you wouldn't need more selenium from Glanzen Complete. The goal, however, is to remain below 3 mg of selenium per day.

I hope this is helpful.

All the best,

Dr. Getty
