BMZ is a Biotin, Methionine and Zinc (organic) supplement.  A quality hoof care topdress formulated specifically to increase hoof growth and integrity.  Methionine is interchangeable with cysteine, a major amino acid of the hoof wall (keritin).  Research has also demonstrated that hoof integrity is directly related to the Zinc content in the hoof.

When you only need 30g per day of BMZ, it's a very cost effective way to assist in hoof re-development.
