Regulation
Two regulatory bodies in North America:
•Health Canada
•Food and Drug Administration (USA)
![Page 8: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/8.jpg)
Regulatory Challenges
• how should Neut. and FF be classified? Foods or Drugs?
• what health claims should be allowed?
• what standards of evidence are necessary?
• how can these be regulated and still allow people to take control of their own health?
![Page 9: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/9.jpg)
Regulation cont'd• Policy needs to take the following into
consideration:
• beneficial products should be available
• regulations should be fair enough to allow promotion of beneficial products
• health claims should be substantiated, truthful, and not misleading, and won't likely lead to harm
![Page 10: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/10.jpg)
Regulation cont'd• food: any article manufactured, sold or
represented for use as food or drink my man, and any ingredient that may be mixed with food for any purposes
• drug: any substance or mixture of substances manufactured, sold, or represented for use in:
• diagnosis, treatment, prevention of disease
• restoring, correcting, or modifying function
• disinfection in premises in which food is manufactured, prepared, or kept
![Page 11: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/11.jpg)
Regulation cont'd• public perception: food v. drug (wellness
v. illness)
• regulation: drugs have much more strict regulations
• Since "food" has more relaxed regulations, and better overall public perception, supplement companies have chosen to list their products under the category of food
![Page 12: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/12.jpg)
Health Claims• requirements for supporting evidence varies
depending on the risk-benefit profile of the product
• standard of evidence should be proportional to the degree of risk
• claim to cure a disease requires HIGH standard of evidence, claim to decrease body fat will have LOW standard of evidence
• companies are not interested in marketing products that are research-driven
![Page 13: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/13.jpg)
Marketing Supplements
• from 1996 - 2000, consumer spending quadrupled (over 25 Billion dollars) due to INTERNET SALES
• no increase in scientific evidence during this time, therefore, marketing was highly influential (and still is)

Doping in Sport
3. Sporting Organizations

•e.g., Tour de France (blood doping, EPO), Waterloo Football Program
![Page 31: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/31.jpg)
Anti-Doping
• Why control doping in sports?
![Page 32: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/32.jpg)
Controlling Doping
• Several reasons:
• safety
• ethical/moral issues
• integrity of sport and competition
• public perception
![Page 33: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/33.jpg)
Safety• deaths and illnesses related to doping and
banned substances are the result of improper use of pharmacological and medical interventions in the pursuit of winning
• Danish cyclists (EPO)
• steroids and brain cancer
• long-term effects when youth dope
![Page 34: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/34.jpg)
Ethics of Doping• it is cheating - unnaturally enhancing your
performance by modifying your own physiology
• there are rules in place
• morally wrong (and very difficult) to intentionally break the rules and try to cover it up
• science of doping is moving faster than the science of testing - athletes need to take responsibility for their own integrity, and the integrity of the sport
![Page 35: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/35.jpg)
Spirit of Sport/Integrity
• When an athlete wins, was it because they were physically superior, better prepared, or were they pharmaceutically enhanced?
• imagine you were one of the competitors in the Tour de France during the past 15 years, and you competed cleanly
• what does that do to your sport?
![Page 36: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/36.jpg)
Public Perception
• People want to see athletes perform at the highest level, athletes want to compete against other clean athletes
• reputation of Lance Armstrong before v. after
• sponsors want to support marketable sports
• reputation of the Tour de France before v. after
![Page 37: Supplements and Erogenic Aids PSE 4U D. Del Duca 2013 (Dr. G. Parise, 2003)](https://reader035.vdocuments.us/reader035/viewer/2022070402/56649f225503460f94c3b44f/html5/thumbnails/37.jpg)
Take Home Points
• Supplements can be beneficial but need to be regulated - lots of gaps in science, marketing, and public knowledge
• doping is unsafe, and can affect the integrity and spirit of sport
