2. According to DeFelice, a nutraceutical can be defined as:
The term “Nutraceutical” is a portmanteau (a linguistic blend) of “Nutrition” & Pharmaceutical” introduced in 1989 by Stephen DeFelice
According to DeFelice, a nutraceutical can be defined as:
“A food (or part of a food) that provides medical or health benefits, including the prevention and/or treatment of a disease”.
Stephen L. DeFelice is the founder and chairman of FIM, the Foundation for Innovation in Medicine

3. However, the term nutraceuticals as commonly used
in marketing has no regulatory definition.
Nutraceuticals can be regarded as:
“A pharmaceutical-grade and standardized nutrient”

4. Other words used in this context include:
Dietary supplementation,
Functional, Multi-functional Foods.
Pharmaconutrients.

5. International sources
Canada
Under Canadian law, a nutraceutical can either be marketed as a food or as a drug; the terms "nutraceutical" and "functional food" have no legal distinction, referring to "a product isolated or purified from foods that is generally sold in medicinal forms not usually associated with food, and is demonstrated to have a physiological benefit or provide protection against chronic disease."
United States
The term "nutraceutical" is not defined by US law. Depending on its ingredients and the claims with which it is marketed, a product is regulated as a drug, dietary supplement, food ingredient, or food.
International sources
In the global market, there are significant product quality issues. Nutraceuticals from the international market aspect may claim to use organic or exotic ingredients, yet the lack of regulation may compromise the safety and effectiveness of products. Companies looking to create a wide profit margin may create unregulated products overseas with low-quality or obscure ingredients wikipedia

No strict definition for nutraceuticals in the European regulation.
If the product modifies the physiological function it is recognized as medicine and if it is merely for health maintenance it is recognized as food.
Concentrated sources of nutrients or other substances with a nutritional or physiological effect whose purpose is to supplement the normal diet. They are marketed “in dose” form i.e. as pills, tablets, capsules, liquids in measured doses etc. (European Commission 2014)

Drugs
Nutraceuticals
Dietary supplements
Egypt
Egyptian pharmacopeia (1984) states that drug is a substance or preparation used for alleviation of or protection against a disease affecting man or animal (Arab Republic of Egypt, 2005)
Nutraceuticals have no strict definition in the Egyptian law
A product to be taken orally that improves the human diet in order to improve body functions and performance.
The dietary supplement is not considered a drug or an alternative for food and is not used alone to treat, diagnose or prevent diseases. It May contain vitamins, minerals, amino acids, fatty acids, herbs, and extracts (Egyptian Drug Authorities, 2009)

9. Why are nutraceuticals gaining global growing recognition?
In recent years, a new diet health paradigm is evolving which places more emphasis on the positive aspects of diet.
Consumers being frustrated with the expensive, high-tech, disease- treatment approach in the modern medicines are seeking complementary or alternative beneficial products.
Nutraceuticals help in combating some of the major health problems of the century such as obesity, cardiovascular diseases, cancer, osteoporosis, arthritis, diabetes, cholesterol…. etc
Conclusively, ‘nutraceutical’ has lead to the new era of medicine and health, in which the food industry has become a research oriented sector.

10. Nutraceutical may range from:
Dietary supplements (Probiotics, Prebiotics, Antioxidants, Enzymes).
Isolated nutrients (Vitamins, Minerals, Amino Acids, Fatty acids).
Herbal products (fresh or dried herbs or botanical products).
Processed products (cereals, soups, and beverages).
Genetically engineered “designer” food.

11. Dietary Supplements
According to the Dietary Supplement Health and Education Act (DSHEA -1994):
A dietary supplement is a product (other than tobacco) that:
Is intended to supplement (reinforce) diet.
Contains one or more dietary ingredients intended to supplement the diet (including vitamins, minerals, herbs or other botanics, amino acids, enzymes ….etc) or their constituents.
Is intended to be taken by mouth as pills, capsules, tablets, soft gels, powders or liquid drinks.
Is labeled on the front panel as being a dietary supplement.

12. Dietary Supplements
Dietary supplements are sold in grocery, health food and drug stores. Also available through mail-order catalogs, TV programs, the Internet and direct sales.
The manufacturer does not have to prove that the supplement is effective. The manufacturer can say that the product addresses a nutrient deficiency, supports health, or reduces the risk of developing a health problem. If the manufacturer does make a claim, it should be stated that "This product has not been evaluated by the Food and Drug Administration, and is not intended to diagnose, treat, cure, or prevent any disease."

13. Intended to affect structure and function of body
Drug
Dietary supplement
Article intended to diagnose, cure, mitigate, treat, or prevent disease
A product intended to supplement diet…etc
Intended to affect structure and function of body
Must undergo FDA approval after clinical studies to determine effectiveness and safety
No FDA approval, just labelling as dietary supplement
Pre-marketing approval and post marking monitoring (pharmacovigilance)
None, only manufacturer is responsible for safety evaluation

14. Intended to affect structure and function of body
Dietary supplement
Functional Foods
Intended to affect structure and function of body
Not intended for this purpose
Not intended as sole item of a meal or a diet & does not substitute conventional food
Can be intended as a sole item, however they don’t substitute conventional food
Must be Labeled with:
Name of each ingredient
Quantity of each ingredient
Total weight of all ingredient if a blend
Identity of part of plant derived from
Term “Dietary Supplement”
None, only may/not contain nutritional labeling information as : Calories, fat, sodium

15. Risks of Dietary Supplements
A Dietary supplement might:
Not contain the ingredient that is listed on the label (such as plant species). For example, one study that analyzed 59 preparations of Echinacea found that about half did not contain the species listed on the label.
Contain higher or lower amounts of the active ingredient.
Use the term “Standardized" to describe efforts to make the product consistent. However, U.S. law does not define standardization. Therefore, the use of this term (or similar terms such as "verified" or "certified") does not guarantee product quality or consistency.
Be contaminated.
