  1. An Introduction to Supplements& Common Supplements Teens Take Sara Oldroyd, MS RD Utah State University Extension

  2. An Introduction • How many of you are currently taking a supplement? • Utah is known nationally for its supplement industry • Xango • Noni • Neutracuetical Corp. • USANA

  3. Dietary Supplement Health and Education Act • Signed Oct 25 1994 • Congress’s intent was to meet the concerns of consumers and manufacturers to help ensure that safe and appropriately labeled products remain available to those who want to use them. • Definition, new framework for safety, outline guidelines for literature displayed, claims, ingredients

  4. Congress passed DSHEA in 1994 on the basis of two quite questionable assumptions: that supplements are basically harmless, and that supplement makers are honest. -Marion Nestle, RD

  5. Unlike drugs, dietary supplements do not have to be proved safe before going on the market, but federal authorities can act to take them off the shelves if they are shown to be unsafe

  6. How To Choose… • Look for standardized supplements (USP) • Buy only single-name supplements • Beware of claims that sound too good to be true • Be extremely cautious about supplements manufactured outside of USA • Europe is an exception

  7. USP The distinctive USP Verified Mark represents that USP has rigorously tested and verified the supplement, to assure the following: 1. What's on the label is in fact in the bottle—all the listed ingredients in the declared amount. 2. The supplement does not contain harmful levels of contaminants. 3. The supplement will break down and release ingredients in the body 4. The supplement has been made under good manufacturing practices. USP is an independent, not-for-profit organization. No other organization in the U.S. that tests supplements is recognized in federal law as the nation's official standard-setting body for medicines and supplements. USP standards are enforceable by the FDA.

  9. Too Good to be True • New Zantrex-3 is serious weight loss... we’re talking about rapid, sustained weight loss and extreme energy, finally together in one power-packed super pill... 5 times more weight loss than the leading ephedrine-based diet pill and all the energy you’ll ever want or need… day or night. • http://micronutra.com/activive.html?aff=1234&kwgroup=av_energy&utm_source=Google&utm_ad=645098913&utm_medium=PPC&utm_campaign=Activive&utm_term=energy%20supplement&gclid=CI73rbPy2IkCFSNdYQodjUwm3g

  10. Remember… • Supplements not meant to replace foods, but to supplement diet • Use peer-reviewed non-biased scientific trials to determine effectiveness • Double blind • Placebo controlled “If it doesn’t have a side effect, it probably doesn’t work.”

  11. Performance Enhancing Supplements • Amino Acid powders/Protein drinks • Creatine • Anabolic Steriods & Precursors • Ephedra

  12. Amino Acids: 21 Million • Amino Acids are building blocks of proteins • Powder form for sport performance/body building • 20 different amino acids, get varying amounts from protein containing foods • Animal products, grains, legumes

  13. Scientific Data • Increases muscle size • Weight gain *Must have training along with supplement Will not make you look like a body builder unless you have type of body to do so. Increase in calories, be careful

  14. Dosing: 1-2 scoops of powder (2-4 Tbsp) before work out, variable upon brand Usually mix with water or milk* Usually whey protein OR Side Effects: Well-tolerated Stomach cramping, diarrhea, weight gain Consider whole foods Dosing and Side Effects

  15. Creatine • Phosphocreatine for energy • ATP -> Phosphocreatine -> Glucose -> Fat • Best used in sports/events needing short bursts of energy • Sprinting • Wrestling • Shot put

  16. Side Effects Nausea Cramping Diarrhea Stomach pain May cause kidney and liver problems Use Most athletes consume 20-30 g/day, but studies done on athletes using 5 g/day, as the manufacturer recommends ~5% of middle and high schoolers had used creatine May lead to more dangerous supplement use Side effects and use

  17. Anabolic Steroids • Synthetic form of testosterone • Gels • Tablets • Injections • Patches • Build muscle and increase endurance • 3 million people use steroids, 1 in 4 started as teens, 1 in 10 is a teen

  20. Used by athletes to reduce fatigue, increase mental awareness, and induce weight loss Weight loss shown when used in combination with caffeine, when used alone results questionable Side Effects Strokes Seizures Heart Attack Increase blood pressure Death Ephedra (Ma Huang)

  21. In 2004, Drug Administration banned ephedra In 2005, Neutraceutical Corporation challenged ban, Utah judge approved due to small doses of ephedra vs. large Most recent 2007 data show ephedra still banned, except in Utah… FDA in hard position since it cannot ethically test ephedra’s safety at low dosages. FDA does think ephedra is harmful. Ephedra

  22. Diet pills • According to a recent study conducted by the University of Michigan, 25% of girls turn to pills when trying to lose weight • In 1992, FDA banned 111 ingredients in over-the-counter diet products--including amino acids, cellulose, and grapefruit extract--after manufacturers were unable to prove that they worked.

  23. Feeling of fullness • A number of products were also recalled because they posed serious health risks. The products contained guar gum, which supposedly swelled in the stomach to provide a feeling of fullness. However, the swelling from the guar gum caused blockages in the throat and stomach. Cal-Ban 3000, Cal-Lite 1000, Cal-Trim 5000, Perma Slim, Bodi Trim, Dictol 7 Plus, Medi Thin, Nature's Way, and East Indian Guar Gum

  24. Fat Blockers • Alli, Orlistat, Xenical Work by inhibiting the lipase enzyme in gut. Without lipase, cannot absorb fats. Recommended to eat less than 15 g of fat with each meal, or else…

Hoodia Green tea extract Country mallow Conjugated linoleic acid (CLA) Chromium Bitter orange No conclusive evidence Large amounts of caffeine Contains ephedra Isn’t likely to reduce total body weight, GI distress Safe, but unlikely to cause weight loss Effects similar to ephedra Other weight loss supplements
