Supplement
i. a substance taken to cure
deficiencies in a person's diet
ii. a manufactured product intended
to supplement the diet when taken
by mouth as a pill, capsule, tablet, or
liquid.
*IMPORTANT*
The U.S. government strictly regulates foods for
ingredients, additives, manufacturing practices,
safety and packaging.
Dietary supplements are not required to be registered
with or obtain pre-market approval by the FDA.
SUPPLEMENT REGULATION
FDA must prove that a supplement is unsafe or has been adulterated
before it can be removed from the market
Manufacturers are not required to share with consumers or the FDA any
information on safety or effectiveness of supplements
Dietary supplements are not well regulated, can cause adverse health
effects and may result in a positive test for banned substances
DID YOU KNOW…
Supplementation
works best when one
has a healthy,
established diet.
COLLAGEN
Most abundant protein in body
Holds it all together
Body produces it
Vit C, Zn, Cu
Amino acids (glycine, proline, lysine)
Supplement → animal bones, skin, CT
Naturally → bone broth
COLLAGEN PEPTIDES
CLAIMS: weight loss, performance, gut health, sleep
No research
RESEARCH: May improve skin and joint health
Skin (topical)
Improve symptoms osteoarthritis, rheumatoid arthritis
COLLAGEN – NAY > YAY
Low Quality (not complete protein)
$43/14 SERVINGS ($3.30/serving)
Quality* protein powder $2/serving
*whey protein (complete)
ADDITIONAL PROTEIN SOURCE
Eat foods that boost collage production
Vitamin E & C
Zinc & Copper
Omega 3’s
Quality protein (amino acids)
PROTEIN POWDER
NOT ALL PROTEIN ISCREATED EQUAL
PROTEIN POWDER
WHEY = MOST POPULAR
Byproducts cheese-making
Liquid → Whey
Curds → Casein, cottage cheese, ricotta
Complete protein
ALL ESSENTIAL AMINO ACIDS
Excellent source BCAAs
Leucine key muscle building
13
Digestion time
Whey (fast) – Post Workout
Casein (slow) – Bedtime, weight gain
Lactose
Whey Isolate
90-99% protein, 1-10% lactose
Whey typically mixes & tastes better
WHEY vs CASEIN
PROTEIN - LABELING
PROTEIN, SUGAR & CALORIES NOT ENOUGH INFO!
Sugar substitutes (bloating, gas, diarrhea)
Avoid pre-exercise
Artificial flavors (look for real vanilla, chocolate)
HFCS & fructose
Carrageenan (GI distress, inflammation)
Mono and diglycerides (potentially hidden trans fats)
3RD PARTY TESTING =
QUALITY & PURITY
PROTEIN POWDER
RED FLAGS
Propriety blend
Hiding true quantity?
Leucine - key muscle synthesis
Not listed
10-11% protein
Cheaper than average
“STEAL” = SCAM
PROTEIN UTLIZATION
Post Workout + Carbs
Restore muscle glycogen stores
Enhance muscle protein synthesis
Smoothie
Oatmeal
Yogurt
Supplemental
1x/day
Protein shakes ≠ diet
Food first
FOOD FIRST
MORE PROTEIN ≠ MORE “GAINZ”
Can only store so much at once
Protein stores continuously replenished
PROTEIN @ EACH FUELING OPPORTUNITY
MEALS
SNACKS
POST WORKOUT
WHEY PROTEIN – YAY > NAY
PLANT-BASED PROTEIN
Plant protein (except soy) → lacks 1+ EAA
Blends = adequate EAAs/BCAAs
Ø necessary at each meal
Key = allo EAAs in throughout the day
PLANT-BASED PROTEIN POWDER - YAY
A well planned,
balanced plant-based
diet can meet protein &
nutrient needs if
consuming a variety of
plant foods and
meeting caloric needs
throughout the day.
MCT OIL
Medium Chain Triglyceride
Triglyceride = Fat
Burned for energy or stored as body fat
MCT = SHORT
More rapidly broken down & absorbed
Less likely to be stored as fat
SOURCES
MCT oil: 100%
(odorless, tasteless)
Coconut oil: > 60%
Palm kernel oil: > 50%
Grass-Fed Dairy : 10–12%
MCT Oil – Benefits?
Weight loss potential
Less calories (10% )
Increased fullness (> leptin)
Less fat storage
Keto diet approved
1-2 lbs more lost 3-12 weeks
NOT SIGINIFICANT
MCT Oil – NAY > YAY

PLATE over PILL
Foods are accompanied by many nonessential but beneficial
nutrients, such as hundreds of carotenoids, flavonoids, minerals,
and antioxidants that aren't in most supplements.
