HHIO Foundation & HHIO Performance's Selenium levels can be customised to your horses needs.

This service is provided based off vet blood tests confirming low or below range Selenium blood levels.

Typically this will be used for several months to increase blood Selenium levels, retest to confirm and then continue with the standard inclusion of 1.5mg organic Selenium per dose.

Saves the hassle of adding an extra Selenium supplement or dose with vet Selenium product.

It is only available for increasing in HHIO Foundation or HHIO Performance.

Purchasing this will provide customization for 1 product only. If you have more than one, then please purchase 2.

The Selenium added is an organic Selenium yeast.
