Today’s Topics
• Introduction to the legal authority

• Structure/function claims
• Boundaries
FDA’s Legal Authority
• Federal Food, Drug, and Cosmetic Act
• Fair Packaging and Labeling Act
Dietary Supplements
• Nutrition Labeling and Education Act (NLEA)
• Dietary Supplement Health and Education Act (DSHEA)
Interpretation of the Statute
• Code of Federal Regulations• Guidance documents• Case law• Informal guidance
What is Food ?
“...articles used for food or drink for man…chewing gum…and articles used for components of...” food or drink or chewing gum
What is a food additive?
• Broad sense: Any substance added to food.• Legally: “Any substance the intended use
of which results or may reasonably be expected to result- directly or indirectly - in its becoming a component or otherwise affecting the characteristics of any food.”– Direct additives– Indirect additives
What is GRAS?
• Substances whose use is generally recognized as safe, based on their extensive history of use in food before 1958, or based on published scientific evidence.
• Not set in concrete!
What is a Drug ?
“…article intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease…”
What is a dietary supplement ?
“…a product (other than tobacco) intended to supplement the diet that bears or contains one or more” designated ingredients
What is a dietary supplement ?
• Vitamin, mineral, amino acid
• Herb or other botanical
• Dietary substance for use by man to supplement the diet by increasing the total dietary intake
What is a dietary supplement ?
• Concentrate, metabolite, constituent, or combination of the ingredients above
What is a dietary supplement ?
• Intended for ingestion• Pill, capsule, liquid, powder, “other”• Not represented for use as
conventional food• Not sole item of meal or diet• Labeled as a dietary supplement
Messages…..
• Definitions and Regulatory “Boxes”
• ….And that they matter
• What to “think about” at this evolving point
Dietary Supplement ComplianceBoundaries
Boundaries
Food
Dietary Supplement
Drug
Which Regulatory Box Is Important Because…..
• Different legal requirements
• Different safety considerations
• Different substantiation for claims
Dietary Supplement or Food ?
Dietary Supplement or Food ?
Food Dietary Supplement
Represented for use as conventional food •Safe ingredients •Claims •Labeling
What is “Functional Food?”
It is undefined but regulated as food
“Functional Food?”
“Functional Food?”
“Functional Food” Claims
Structure/function claims
Truthful Non-misleading
Based on nutritive value
No drug claims
“Functional Food” Claims
Disease claims - Drug• Dietary support during the
cold and flu season• Prevents the onset of disease
complications
Dietary Supplement Drug
Structure/function claims
• 30-day post-market notification for structure/ function claim
• Use of “disclaimer”• Manufacturer is responsible for substantiation
30-Day Notification
Disease claims - Drug• Reduces cholesterol
• Reduces fever• Helps promote normal body function
after taking too much drink
30-Day Notification
Structure/function claim
• Gingko biloba promotes healthy brain function • Guar gum promotes healthy intestinal function • Helps maintain cholesterol levels in normal
range
The Key to Almost Everything Is……….
Intended Use
(claims)
Intended Use Gets You into Two Possible Boxes…. initially
Functional Food
DrugsPrescription
OTC
Foods
Conv Foods Dietary
Supplements
?
More on This Perspective
• Functional Foods-------> Assumption: probably about foods
• Dietary supplements are intended to supplement the diet
What’s the Difference?
• Conv Foods versus Dietary Supplements
– Safety Standard• Conv Food: GRAS/Food Additive• Dietary Supplm: Signif-Unreasonable Risk
– Claim topic / substantiation• Disease endpoint / Same: Rigorous--Pre-review• Non-disease endpoint / Essentially Same* =Truthful/Not Misleading
*What’s the Difference?
• Nutritive Value / Food-Like Effect– Characterizes oversight of conv food claims– Not well defined or articulated– DSHEA specifies that dietary supplements do
not have to have nutritive effect– Point of resolution:
• NV Needed? Drug versus Food?• What does it mean scientifically today?
More on This Perspective
• Do Functional Foods need their own regulatory box?– Probably not
• Do they need some special considerations?– Probably yes
Food - Dietary Supplement - Drug
• Chewing Gum
• Breakfast cereal type products
• Product in bar form
• Bottled water
