It is important for a horse to get enough vitamins and minerals. Sometimes the horse cannot get these enough from its feed. Equistro Mega Base can then provide a solution. This supplement contains minerals, vitamins, trace elements and amino acids and can help make up for a deficiency in these. Mega Base is a mineral concentrate and contains four trace elements, fat-soluble vitamins, minerals and DL-methionine (an essential amino acid). The selected nutrients support the skeleton, joint cartilage and connective tissue.
