Nutritional Supplements – An Overview

 The term nutritional supplement, or dietary supplement, is rather loosely defined but may be considered a product that contains one or more ingredients (such as vitamins or amino acids) that are intended to supplement one’s diet usually on the basis of improving an imperfect diet.

Medical Foods – A Specific Category of Nutritional Supplement

Medical foods are defined by the FDA as “a food which is formulated to be consumed or administered under the supervision of a physician and which is intended for the specific dietary management of a disease or condition for which distinctive nutritional requirements, based on recognized scientific principles, are established by medical evaluation.”


Medical foods must be prescribed by a physician after a diagnosis has been made, yet they are not regulated as drugs, and are not subject to the regulatory requirements that apply to drugs. They are also exempt from food labeling requirements pertaining to health claims under the Nutritional Labeling Act. Medical foods are also distinct from nutritional supplements, although their regulations are similar.


Medical foods present minimal concerns for drug interactions or risk of long-term complications. In addition, because medical foods have unique mechanisms of action (ie, amino acids that are essential for the synthesis of neurotransmitters responsible for transmitting pain signals and influencing their perception), medical foods may also be used in combination with traditional medications, enhancing their benefit and potentially allowing a reduction in their dose.


Growing concerns about prescription analgesics and their complications has resulted in greater interest and research in the role of nutrition and food in the management of pain. The use of foods as medicine provides a an approach that is “generally regarded as safe” (GRAS) as a supplemental or alternative to treating pain.

How to Select Supplement to Insure Safety and Effectiveness

When selecting therapeutic supplements, it is important to take several considerations into account prior to purchasing a commercial product. First, not all labels are accurate as to content.


To help assure that a product is one of high quality and effectiveness, look for the following labels:

• USP seal of approval

• GMP seal of approval

• NSF seal of approval

• “Clinically Tested”


Not all supplements are well aborbed either from the gut into the bloodstream, from the blood stream into a tissue and then into the target cell or cross the “blood brain barrier” that restricts many substances from entering the brain and nervous system. The term that reflects how well a substance that is taken orally then reaches the intended target tissue or cellular component is “bioavailability.” The extent to which a supplement is bioavailable is a major factor contributing to it’s effectiveness. To read more on recent advances in improving the bioavailability of many nutritional or therapeutic substances, see “Nanoformulations” below.

Because vitamins, minerals, antioxidants and other nutrients are present naturally in many vegetables and fruits, when we eat these foods we reap the benefits.


But do we?

The truth is sometimes yes, sometimes no. When we cook plant foods, many antioxidants are destroyed, sometimes as much as 97%. Unfortunately, even when eaten raw the antioxidants in food are often poorly absorbed through the stomach or intestines. Even when they get absorbed into the blood, they may have poor penetration into cells, especially into the brain and nervous system. In many cases the antioxidants we ingest simply do not get to where they can do the most benefit: within the cells. In other words, nutrients in our food are sometimes not very bioavailable (not available to the cells that need them).



Over the last few years, science has developed new techniques to overcome the problem of bioavailability, including use of nanoformulations. Nanoformulations reduce the size of the nutrient particles down to tiny micron levels and sometimes attach the nutrient to a second component that allows for the particle to be much better absorbed. Studies have demonstrated that nanoforumulations such as “phytosomal curcumin” have improved absorption as much as 29 times more effective.


Microsizing and nanoformulations are revolutionizing the pharmaceutical industry by providing the means to allow medications and nutrients that are poorly absorbed to become effectively absorbable and bioavailable. Currently, many medications and nutrients have been nanoformulated include curcumin, quercitin, grape seed extract and green tea extract.

Online Resources for Nutritional Information
This is my favorite online resource for nutritional information. It provides excellent breakdowns of the nutrional value of natural foods, raw and cooked, as well as commercial food products. It offers a web-based app that allows you to track and analyze your diet and monitor your exercise. It has a wealth of educational information on topics from food additives, glycemic index, food processing, individual nutrients and pretty much anything of interest to the person motivated to learn more about diet and nutrition. There are even recipes! provides easy access to vetted food and nutrition information from across the federal government. It serves as a gateway to reliable information on nutrition, healthy eating, physical activity, and food safety for consumers. Since dietary needs change throughout the lifespan, specialized nutrition information is provided about infants, children, teens, adult women and men, and seniors. Users can find practical information on healthy eating, dietary supplements, fitness and how to keep food safe. The site is kept fresh with the latest news and features links to interesting sites.


 National Association to Advance Fat Acceptance
Founded in 1969, the National Association to Advance Fat Acceptance (NAAFA) is a non-profit, all volunteer, civil rights organization dedicated to protecting the rights and improving the quality of life for fat people. NAAFA works to eliminate discrimination based on body size and provide fat people with the tools for self-empowerment through advocacy, public education, and support.
