What the medical profession has forgotten, for the most part, is that feeding tube formulas used to be prepared from real food and used to be the standard of care in hospitals and long term care facilities. Functional Formularies products meet all food safety requirements and meet all GRAS, HACCP, and CGMP standards. Functional Formularies products are produced in an FDA/USDA registered facility with a USDA inspector on site. They undergo thorough testing before they are released from the manufacturer. They are both shelf-stable, require no refrigeration, and have a two year shelf life. We believe we have the ideal real foods formulas that are a true meal replacement and can be someone’s sole source of nutrition.
