INORGANIC SELENIUM IN MY HOOF SUPPLEMENT

Customer:

As I am just beginning to better understand the needs and issues of selenium, I have a question about inorganic selenium in small (1 mg/day) quantities.  I have athletic American Saddlebreds that I use as endurance horses. Currently, they are fed HorseGuard in addition to 60/40 grass/alfalfa here in the eastern parts of the Pacific Northwest.  My 4-year old could benefit from the addition of Biotin and I mistakenly ordered one that contains an addition of 1mg of sodium selenite per day.  Is this dangerous or, based on the info on this website, will the body largely waste this?

Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:

The biotin product with 1 mg of selenium will put your horse at 4 mgs total. Research studies have been done with this amount and found no problems when supplemented at this level for six months. So your 4-year-old will be ok with that supplementation.

In your next purchase of a biotin supplement you should consider our hoof supplement, Hoof Guard. It has no selenium and contains 32 mg of biotin, zinc, methionine, and MSM. We also have a product called Mega Dose that contains a full dose of Horse Guard and 32 mg of biotin in a single dose for ease in feeding.
