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
