Question: Is it permissible to make the claim "balances intestinal flora" on the label or advertisement for a bacterial culture?
Answer: No, the claim "balances intestinal flora" is
considered to bring the food within the definition of a drug and is not
acceptable on the label or advertisement of a food. The term
"balance" is also considered unacceptable, as it implies a
physiological effect. Products carrying these claims would be required to carry
a Drug Identification Number (DIN) issued by the Health Products and Food
Branch of Health Canada. (25 Nov 92)
