3. Overview on supplements
• Nutritional supplements are often times referred to as “dietary
supplements.”
• “A dietary supplement is a product intended for ingestion that
contains a “dietary ingredient” intended to add further
nutritional value to (supplement) the diet. (www.fda.gov)
• Often time the ingredient will include one or more of the
following substances:
• minerals, vitamins, herb, a concentrate (metabolite,
constituent, or extract), an amino acid.
• Supplements are found in forms such as capsules, gelcaps,
liquids, tablets, or powders.
• Supplements can help you get adequate dietary intake of
essential nutrients and help reduce your risk of disease.

4. • The word “supplement” means a nutrient or group of nutrients that
are meant to supplement.
• This does not mean it is meant to substitute a healthy diet you can
eat regularly.
• Do you view supplements as an “easy way out” in regard to healthy
eating and living?

5. Definition
• A dietary supplement, also known as food supplement or nutritional
supplement, is a preparation intended to supplement the diet and
provide nutrients, such as vitamins, minerals, fiber, fatty acids, or
amino acids, that may be missing or may not be consumed in
sufficient quantities in a person's diet.
• In the United States, a dietary supplement is defined under the
Dietary Supplement Health and Education Act of 1994 (DSHEA) as a
product that is intended to supplement the diet and contains any of
the following dietary ingredients:
• - a vitamin
• - a mineral
• - a herb or other botanical (excluding tobacco)
• - an amino acid
• - a concentrate, metabolite, constituent, extract, or combination of any of the above
• - a substance historically used by humans to supplement the diet

6. • It must also conform to the following criteria:
• Intended for ingestion in pill, capsule, tablet, powder or liquid form
• Not represented for use as a conventional food or as the sole item of a
meal or diet
• Labeled as a "dietary supplement"

7. Facts about Supplements
• More than 1000 new supplements are developed each year.
• Large and small companies produce supplements.
• Supplements have been touted to treat almost every
condition known to man.
• Claims by those who market supplements frequently have
no basis in science.
• People take supplements for a variety of reasons.
• Only about a third of dietary supplements have scientific
evidence of safety and effectiveness.
• Supplements can interact with medications.

8. Should you be taking supplements?
•IF you are eating a reasonable variety of fruits,
vegetables, proteins, carbohydrates, and healthy
fats you probably do not need a general vitamin-
mineral supplement.
•Often time they way you eat and what you eat will
play a key role in how you feel physically and
mentally. If you are physically tired from a poor
diet, a supplement will not add extra energy. Only
better nutrition can help you.
•Supplements can NEVER make up for poor eating
habits.

9. That being said….
• Because of food allergies, the inability to obtain needed nutrients, or
medical conditions, some people do need specific supplements.
• Calcium, Iron, Vitamin C, and Folate are some examples of vitamins
that are often times supplemented along with a healthy diet. It is
always encouraged that you try your best to get these vitamins
strictly from food. But if you find you are lacking in certain areas, then
it is best to add a vitamin along with your healthy eating.
• IF you fall into any of the following groups, you may require
supplements. Of course always talk to your Doctor before starting a
supplement!
• Pregnant women
• Nursing mothers
• Strict vegetarians
• People with food allergies
• Senior Citizens

10. What about protein powders?
•People spend so much money on protein supplements
hoping it will help build muscle fast! However this just
isn’t the case.
•When you take a high level of protein it is actually
converted to fats and carbohydrates in the body.
Excess protein can cause too much burden on your
kidneys, cause calcium loss and dehydration.
•By simply increasing protein in your diet slightly, you
can meet your protein needs.

11. Regulation of dietary Supplements
•The U.S. Federal Trade Commission has primary
responsibility for regulating advertisement and
labeling.
•Aside from advertising, regulation is by the Food and
Drug Administration.
•FDA regulation is hampered by the fact that
supplements are usually treated as foods, not drugs.
•FDA does not analyze the content of supplements
and cannot insure the ingredients or their amounts
listed on the label are accurate.
11

12. Dietary Supplement and Health Education Act
•Governs federal regulation of dietary supplements.
•Limits FDA ability to regulate supplements.
•Prohibits the FDA from banning suspicious
ingredients.
•Allows label statements about effects on the
structure or functioning of the body if they contain a
disclaimer statement.
•Expanded the types of products that can be marketed
as supplements.
