Dietary supplementation is growing in popularity. While most Americans take at least one dietary supplement, many people are confused by the regulation, safety, and efficacy of the supplements that they consume. Dr. D’Adamo will clarify these issues and present the latest research on specific dietary supplements that are effective as well as those that may be best to avoid. Learn about popular dietary supplements that are being taken for a wide variety of health conditions — ranging from arthritis, to immune system enhancement, to depression — and become a more informed consumer when choosing supplements.

4. Dietary Supplements Defined
What is a dietary supplement?
1994 Dietary Supplement Health and Education Act
(DSHEA)
A product (other than tobacco) intended to supplement diet
Contains one or more dietary ingredients and taken orally
Vitamins, minerals, herbs or other botanicals, amino acids
Vitamins Minerals Herbs Amino Acids
Immune System
5. Regulation of Dietary Supplements
Federal Regulation of Dietary Supplements
Food and Drug Administration (FDA)
Supplements regulated as food
Pre-DSHEA assumed safe, post-DSHEA provide safety evidence
Labeling and claims requirements
Ingredient names & amounts, directions for use, no health claims, etc.
2007 Good Manufacturing Practices (GMP)
Quality standards for manufacturing, preparation, storage, facility
Federal Trade Commission (FTC)
Regulate marketing of supplements
6. Regulation of Dietary Supplements
Federal Regulation of Dietary Supplements
No universal regulation of supplement content
“Don’t know what you’re getting”… in many cases, true!
Many dietary supplement companies hire 3rd
party
laboratories for product purity certification
Contains specified ingredients
No contaminants
Dissolves properly
GMP compliant
Some 3rd
party labs better than others
NSF-certified gold standard
8. Multivitamin: Overview
Most common dietary supplement
33% of Americans take multivitamin
Usually contain at least 13 vitamins &
15 minerals most important to nutrition
How multivitamins are used
Generally capsule or tablet orally once per day
Powders, liquids, multiple daily doses less common
Best taken with meal
Many of nutrients lipid-soluble, need fat for absorption
9. Multivitamin: Types
RDI-centric
RDI of most important vitamins/minerals
Reference Daily Intake – replaced RDA in 1997
Prevent micronutrient deficiency in most people
"% Daily Value" on food & supplement labels
Widely available
Higher potency
Exceeds RDI for many vitamins/minerals
Why? RDI prevent deficiency disease…
not to promote optimal health!
Higher in vitamin D, B-vitamins, vitamin C, etc.
Health stores, clinical practices, Amazon, etc.
10. Multivitamin: Favorable Research
Improves nutritional status
2000 Journal of American College of Nutrition, 2009 European Journal Clinical Nutrition
Reduces risk of birth defects
2001 Epidemiology, 2002 Epidemiology, 2002 Pediatrics, 2003 Pediatrics
Associated with weight loss & decrease in body-fat %
2010 International Journal of Obesity Research
Reduced risk of macular degeneration & cataracts
2007 American Journal of Clinical Nutrition, 2008 Ophthalmology
Reduces risk of heart attack
2010 American Journal of Clinical Nutrition
Reduces risk of colon cancer
2002 Cancer Epidemiology, Biomarkers, & Prevention
Reduces risk of all-cause mortality and cancer mortality
2011 European Journal of Nutrition
11. Multivitamin: Unfavorable Research
No benefit in some studies
No reduction in risk of cancer or cardiovascular disease
2009 Archives of Internal Medicine
No reduction in risk of breast cancer
2010 Public Health Nutrition, 2010 American Journal of Clinical Nutrition
Slight increase in non-cancer, non-CVD mortality
Lots of media coverage… but study flawed and over-interpreted
2011 Archives of Internal Medicine
Direct conflict with 2011 European Journal of Nutrition Study!
12. Multivitamin: Recommendations
Does brand make a difference? YES!
Cheap brands use cheap vitamin/mineral forms
Affects absorption and effectiveness
Natural vitamin forms better absorbed than synthetic
Natural vitamin E twice absorption of synthetic
Certain vitamin forms more effective than others
Vitamin D3 superior to vitamin D2
Certain mineral binding salts better absorbed than others
Magnesium citrate much better absorption than magnesium oxide
13. Multivitamin: Recommendations
How to choose a good brand?
www.multivitaminguide.org
Ranking based on: composition, bioavailability, synergistic effect, potency
101 of most common multivitamins in United States
Comparative Guide to Nutritional Supplements
Lyle MacWilliam, biochemist, commissioned by Canadian Minister of Health
Scientific analysis of 510 multivitamins available in United States & Canada
15. Multivitamin: Recommendations
Quality is key! Consult rankings
Whole-food based multivitamins also good choice
Synergy between hundreds of food components!
Always consume with meal
Important fat-soluble nutrients
Poor absorption in absence of fat
Be an informed consumer! Choose/avoid the following…
Vit E: d-alpha tocopherol (natural) NOT dl-alpha tocopherol
(synthetic)
Vit E: look for "mixed tocopherols" and/or "gamma tocopherol"
Vitamin D3 NOT vitamin D2
Methylcobalamin form of B12 NOT cynacobalamin form of B12
Avoid oxide binding salts (magnesium citrate NOT magnesium oxide)
16. Vitamin D: Overview
A uniquely important vitamin
Hormone-like activity (secosteroid)
Controls expression of over 200 genes
Vitamin D active in most biological systems
Musculoskeletal system
Classically emphasized role
Endocrine system
Nervous system
Cardiovascular system
Digestive system
Immune system
17. Vitamin D: Sources
Sun exposure
UVB light converted to vitamin D3 in skin
D3 transported to liver, metabolized to 25(OH)D
Also called calcidiol… measured most vitamin D blood tests
25(OH)D converted to calcitriol in kidneys
Calcium metabolism… remaining calcitriol & calcidiol → health benefits
20,000 international units (IU) from 30 minutes sun exposure
Only spring and summer if north of Atlanta
Limited amount from foods
D3 from oily fish, eggs, butter, cheese, fortified milk/cereals
Vitamin D fat-soluble… needs fat for absorption
10-100 IU: depending upon source
Supplements deliver much higher doses… up to 5,000+ IU per pill
18. Vitamin D: Reference Daily Intake
Current RDI varies
Up to age 50: 200 IU
Age 51-70: 400 IU
70 and older: 600 IU
Amount to prevent vitamin D deficiency
Rickets
Softening of bones → deformities, fractures, etc.
Most common in children… rare in United States
Also occurs in adults… called osteomalacia
Amount to prevent chronic disease… much higher!
Call to substantially increase RDI to at least 1,000 IU
Explosion in vitamin D research
19. Vitamin D: Favorable Research
Prevents bone disorders (osteoporosis, fractures, etc.)
2009 Cochrane Systematic Database Review
Reduced risk of cancers (breast, colon, prostate, etc.)
2004 American Journal of Clinical Nutrition, 2009 Cancer Epidemiology
Improved survival among colorectal cancer patients
2012 Cancer Epidemiology, Biomarkers and Prevention
Reduced risk and better control of diabetes
2010 Diabetes, Obesity, & Metabolism, 2010 Diabetes Care
Reduced risk of obesity
2010 Obesity, 2010 Diabetes, 2009 Journal of American Dietetic Association
Help weight loss & improve cardiovascular risk factors
2012 British Journal of Nutrition
Reduced risk of cardiovascular disease
2009 Archives of Internal Medicine, 2010 American Journal of Cardiology
20. Vitamin D: Favorable Research
Improve depression & Seasonal Affective Disorder
2008 Journal of Internal Medicine, 1999 Journal of Nutrition, Health, & Aging
Reduced risk of Crohn’s disease, rheumatoid arthritis,
multiple sclerosis and other auto-immune disorders
2010 Journal of Rheumatology, 2007 American Journal of Clinical Nutrition
Stimulate immune system to prevent infection
2010 American Journal of Clinical Nutrition
Decreased risk of all-cause mortality
2008 Archives of Internal Medicine
21. Vitamin D: Unfavorable Research
Vitamin D supplementation not beneficial in some trials
Breast cancer – 2009 Breast Cancer Research and Treatment
Heart attack – 2007 Circulation
Between 200 – 400 IU vitamin D used… very low dose
No risks of high serum vitamin D in observational studies
Unless extremely high concentrations over 100 ng/mL
Increased risk of atrial fibrillation “excess” 25(OH) D > 100 ng/mL
Vitamin D increases calcium absorption… too much calcium in blood?
No evidence of harm from typical vitamin D supplements
Fat-soluble, but safe at even at very high intake
Acute D3 toxicity intake ≈ 176,000,000 IU… 440,000 400 IU capsules
Only toxic cases manufacturing mistakes (extremely rare)
22. Vitamin D: Recommendations
Convincing evidence: recommend 25(OH)D test to everyone!
Vitamin D inadequacy extremely common
Between 36-100% depending on group, 2006 Mayo Clinic Proceedings
Supplementation most important for people who…
Live north of Atlanta (in fall & winter)
Cannot synthesize from sun
Have darker skin tone
Less efficient synthesis in skin
Older adults
Greater risk of osteoporosis & other chronic diseases
Avoid sun or wear sunscreen
Most vitamin D from sun exposure
Have low serum 25(OH)D
Everyone should have vitamin D tested… inexpensive and major risk-factor!
23. Vitamin D: Recommendations
Not much difference by price or brand
Gel capsule preferable to tablet
Vitamin D fat-soluble… better absorption
Take with food
Vitamin D fat-soluble
Vitamin D3 preferable to D2
D3 (cholecalciferol) more effective than D2 (ergocalficerol)
2004 Clinical Endocrinology & Metabolism
Serum 25(OH)D target range ≈ 40 ng/mL (100 nmol/L)
More research needed for optimal threshold… most people low!
24. Omega-3 Fats: Overview
Class of polyunsaturated fatty acids (PUFA)
Common structure (C=C in n-3 position)
Three nutritionally important omega-3 fats
Alpha-linolenic acid (ALA)
One of two essential fatty acids
“Short-chain”… converts to “long-chain”
Eicosapentaenoic acid (EPA)
Long-chain omega-3
Docosahexaenoic acid (DHA)
Long-chain omega-3
Health benefits of EPA and DHA most studied
Precursor to eicosanoids… anti-inflammatory effects
25. Omega-3 Fats: Sources
Vary by type of omega-3
ALA
Nuts, seeds, vegetables
Flax seed, chia seed, walnuts, leafy greens
EPA/DHA
Oily fish
Salmon, sardines, mackerel, tuna, etc.
Other animal products
Depends on animal's diet… grass-fed beef and pastured eggs
Seaweed
Generally DHA only
Fortified foods
Milk, yogurt, cereals, etc.
26. Omega-3 Fats: Rationale
Standard American Diet ("SAD") low in Omega-3
Evolved on diet with ≈ even omega-6:omega-3 (1:1)
"Paleo-style diet" - Fish, grass-fed meat, vegetables, fruits, etc.
Both omega-6 & omega-3 necessary
Linoleic acid (omega-6) an EFA
Imbalance affects inflammatory cascade… especially if too much omega-6
Standard American Diet…
20:1 omega-6:omega-3!
MUCH higher in many cases
Recent changes… industrialization of food supply
Grain-fed beef, soybean oil, corn oil, etc.
Thought to play role in auto-immune & inflammatory conditions
27. Omega-3 Fats: Favorable Research
More clinical research than any vitamins
All studies below RCT’s or reviews of RCT’s
Improved many auto-immune conditions
Rheumatoid arthritis, Irritable Bowel Syndrome, asthma, etc.
2009 Cochrane Systematic Review, 2005 Nutrition, 2000 American Journal
of Clinical Nutrition, 2000 European Respiratory Journal
Reduced blood pressure
2002 Journal of Hypertension
Lowers triglycerides
2009 Nutrition and Health
Decreased cardiovascular disease events and mortality
2006 American Journal of Clinical Nutrition, 2008 British Medical Journal,
2009 Clinical Cardiology, 2009 Annals of Internal Medicine
28. Omega-3 Fats: Favorable Research
Helps treat depression
2009 & 2010 Journal of American College of Nutrition
Helps manage bipolar disorder
2009 European Journal of Clinical Nutrition
Prevention of psychotic disorder among high-risk
2010 Archives of General Psychiatry
Reduction in ADHD symptoms
2009 Journal of Attention Disorders
Decreased cognitive decline in older adults
2011 Journal of Nutrition, Aging, and Health
29. Omega-3 Fats: Unfavorable Research
Some clinical trials found no benefit
ADHD
2001 Journal of Pediatrics
Cognitive performance
2008 Neurology
Schizophrenia
2001 American Journal of Psychiatry
No clinical studies showing harm
But be aware of potential interaction with anticoagulants
30. Omega-3 Fats: Recommendations
Convincing evidence: recommend to most people
Not recommended for people on anticoagulant drugs
Coumadin, etc.
Omega-3 supplements can thin blood
Most important for people who…
Don’t eat fatty, cold-water fish
Vegetarians/vegans… ALA poorly converted to EPA/DHA
Flounder, catfish, etc. no omega-3
Have autoimmune or chronic inflammatory conditions
Have high triglycerides or are at high risk for heart disease
Eat Standard American Diet
31. Omega-3 Fats: Recommendations
Supplement with ALA or DHA/EPA?
Flaxseed oil (ALA) vs. fish oil (EPA/DHA)
Fish oil superior to flaxseed oil
ALA conversion to EPA/DHA very poor!
Only 8 to 20% ALA converted to EPA/DHA
2008 Nutrition Reviews
Most omega-3 benefits from EPA/DHA
Krill oil another good source of EPA/DHA
If vegetarian/vegan
Consider algae-based omega-3 supplement
32. Probiotics: Overview
Probiotics defined: World Health Organization
“Live micro-organisms… administered in adequate
amounts, confer beneficial health effect on the host”
Probiotics can be bacteria or yeasts
Bacteria much more abundant… bigger role in health
Primarily colonize or transiently act in gastrointestinal tract
Why are gut bacteria important?
Over 100 trillion bacteria in gut
Ten times amount of cells in human body!
500 different species of bacteria in gut
Critical role in metabolism and immune system
33. Probiotics: Important Varieties
Three classifications of probiotics
Genus – broadest
Species – more specific
Strain – most specific
Most probiotic supplements classified by genus & species only
Lactobacillus
One of most common bacterial genera in gut
Convert lactose & other sugars to lactic acid
Can help some with lactose intolerance
Acidic environment inhibits harmful bacteria
Over 100 species
Indicated by L. _______
Some of most important: L. acidophilus, L. casei, L. reuteri, L. brevis
34. Probiotics: Important Varieties
Bifidobacterium
Another common bacterial genera in gut
Inhibit pathogenic bacteria
Competes for resources & produces lactic acid
29 species identified
Indicated by B. _______
Some of most important: B. longum, B. breve, B. animalis
Saccharomyces
Common fungal genus in gut
Most yeast damage gut, e.g. Candida Albicans
Some species compete with pathogens
Indicated by S. _______
S. Boulardii prevents/treats GI disorders
35. Probiotics: Dietary Sources
Fermented foods
Component of most traditional diets
Asian
Miso and natto
Fermented beans/grains… often soy
L. acidophilus (miso) & B. natto (natto)
Kimchi
Fermented cabbage, radishes, etc.
L. kimchii
Kombucha
Fermented tea
S. cerevisiae
36. Probiotics: Dietary Sources
European
Yogurt

Cow, goat, sheep milk
L. bulgaricus & Streptococcus thermophilus
Kefir
Also fermented dairy
More probiotic species than yogurt
L. rhamnosus, B. longum, S. florentinus, etc.
Sauerkraut
Fermented cabbage
L. plantarum, L. mesenteroides, etc.
37. Probiotics: Dietary Sources
African
Ogi
Fermented grains… often corn
L. brevis, L. acidophilus, etc.
Currently in United States…
Primarily yogurt
Traditional products available health food stores
Kefir, kimchi, kombucha, etc.
38. Probiotics: Supplement Rationale
Americans consume few fermented foods!
Commercial yogurt not optimal source
Often high in sugar… feeds yeast & pathogens
Relatively low bacterial count
100 million lactic acid bacteria per serving… 100 trillion bacteria in gut
39. Probiotics: Favorable Research
Most clinical research of all dietary supplements
All clinical trials or reviews of clinical trials
Major species listed for each outcome
Regulates bowel function
Effective against diarrhea… especially antibiotic-associated
L. rhamnosus GG, S. Boulardii, L. Bulgaricus and many others
2012 Journal of American Medical Association
Effective against constipation

42. Probiotics: Unfavorable Research
Ineffective in some trials for certain conditions
Crohn’s Disease
2008 Digestive Disease and Sciences
Pancreatitis (feeding tube)
2008 Lancet
No evidence of harm from oral probiotic supplementation
Not necessarily harmless… more research needed
43. Probiotics: Recommendations
Recommend to people eating Standard American Diet
Usually not necessary if consume variety of fermented foods
Don’t typically need to take on an ongoing basis
Cycle on and off occasionally... few times a year or specific situations
Most important for people who…
HAVE BEEN ON ANTIBIOTICS!
Critical to replenish flora & prevent side-effects
Have digestive problems and/or food intolerances
Will be travelling out of the country
Prevent diarrheal disorders
Have an autoimmune condition
Are at high risk for infections
Especially useful during flu season
44. Probiotics: Recommendations
Core product: contains genus & species variety
Especially Lactobacillus & Bifidobacterium
Occasionally rotate products for increased variety
Specific conditions: single-species okay
S. boulardii, L. GG, etc. for diarrhea
Choose high potency products
At least 5 billion colony forming units (CFU)
≥ 10 billion preferable… especially after antibiotics
Many products contain over 100 billion CFU
Remember… 100 trillion bacteria in gut!
45. Probiotics: Recommendations
Choose refrigerated product during summer
Probiotics die if exposed to high temperatures
Refrigerating extends life & assures potency
Choose products that specify strain
Most specify genus and species
Best products also specify strain!
Choose products supported by research
Probiotic supplements vary tremendously
Trust those supported by research
Company can point to studies
47. Supplements to Avoid
Most supplements safe… but some may pose risk
Especially products tainted with pharmaceuticals
Three classes of supplements most likely to be tainted
Weight-loss supplements
Not likely to be effective long-term
Cannot replace healthy diet & exercise habits
Often stimulant-based… contraindications?
Especially among overweight
Some products tainted with sibutramine
Active ingredient in Reductil (withdrawn by FDA)
Increases blood pressure, pulse, potential risk for CVD events
http://www.fda.gov/Drugs/ResourcesForYou/Consumers/BuyingUsingM
48. Supplements to Avoid

aka “CoQ10”
These medications deplete CoQ10
Coenzyme Q10 supplementation recommended
2006 Annals of Pharmacotherapy
Also good idea to take with Red Yeast Rice
Why is supplementing with CoQ10 important?
Critical in muscle function… particularly heart
Reduces cardiovascular disease risk and blood pressure
2007 Nutrition Review & 2006 Journal of Cardiac Failure
Reduces statin-induced muscle myopathy
2007 American Journal of Cardiology
53. Supplements for Special Situations
Vitamin B12 for people on stomach acid-blockers
Prilosec, Zantac, antacids, etc.
These medications deplete vitamin B12
Reduced stomach acid to absorb B12
Why is vitamin B12 important?
