A. The Board shall have authority to promulgate regulations regulating the sale of vitamins or food supplements by any practitioner of the healing arts from the office in which he practices.
B. A chiropractor may recommend or direct patients on the use of vitamins, minerals, or food supplements, provided that the rationale for such recommendation is (i) documented in a patient's record and (ii) based on a reasonable expectation that the use of such vitamins, minerals, or food supplements will result in a favorable patient outcome, including preventive practices, and that a greater benefit will be achieved than that which can be expected without such use. Such chiropractor shall not sell, dispense, or recommend vitamins, minerals, or food supplements for use if such use will negatively impact any of the patient's existing medical conditions.
