Since 1984, every Metabolic Maintenance Product has been manufactured with active ingredients only. Purity is essential for maximum benefit and it has been their core belief since day one. In 1994, Metabolic Maintenance Products moved into a new, state-of-the-art production facility designed to reflect the rigorous standards of the pharmaceutical industry. Some of these standards are currently known as "Good Manufacturing Practices" which they helped to pioneer. Their complete compliance with all "GMP's" is assured and reflected in their unconditional guarantee of every one of their products.
