My 24 year old PRE has Okapi minerals . I know they are in the correct format and do not contain Organic Selenium . They do contain Sodium Selenite , the inorganic form of Selenium which the horse is able to excrete if the mineral reserves are full unlike Organic Selenium often known as Selenium yeast .
Why is it a problem if we feed Organic Selenium ?
The horse is unable to excrete the excess which is stored in the tissues including connective tissue which then weakens over continual supplementation. Think tendons and ligaments .. suspensory ligaments in particular.. 😳
It is also responsible for IR in some horses as the Selenium takes over the cell and blocks the uptake of glucose …
Check your feed and supplements people .. Organic Selenium is in much of what we feed our horses .. 😔.
