Love this product. Seams to have made a great difference based on my horse's blood analysis.

Totally satisfied with product and timely delivery.

Great product! Does the trick ;)

My mare is in Quebec where the selenium level in forage is very low. I have blood tests done every year for selenium. Earlier this year I had her started on mad barn selenium and tested three weeks weeks later. The selenium was well within the norm! The loading for those those three weeks was four scoops daily. I now have her on a regular one scoop daily.. will test again in the winter. She will never ingest feeds with supplements powders of any kind! These commercial pellets are one way to ensure she takes it all in.

very good product

Really like this product and will continue to use it. 5 Star rating.
