Supplements Flashcards
Current Good Manufacturing Practices (cGMP)
Current standards of practice set forth by the U.S. Food and Drug Manufacturers for dietary supplement manufactures
Maslow’s Hierarchy of Needs
- meet daily energy needs for healthy living
- meet daily protein needs for desired outcome
- tailor energy intake for specific goals
- identify gaps in diet and meet micro-nutrient standards
- implement ergogenic strategies for specific goals

Muscle-Gain Supplements with Strong Evidence
-protein
-creatine monohydrate
-essential amino acids
Muscle-Gain Supplements with Moderate Evidence
-BCAAs
-HMB
-Phosphatidic acid
Muscle-Gain Supplements with Weak Evidence
-Arginine
-Glutamine
-ATP
-Alpha-ketoglutarate
-Prohormones
where is Creatine monohydrate synthesized?
it is synthesized endogenously in the liver and kidneys from amino acids and is stored primarily in muscle tissue
role of creatine monohydrate
regenerate intracellular ATP stores via the phosphocreatine system during high-intensity activity
Protein Balance
The net result of protein synthesis and breakdown.
Anabolic Resistance
A blunted muscle synthesis response to resistance training, amino acids, and protein – observed more in older adults than younger populations.
Leucine
An essential and branched chain amino acid, identified as the initiator of muscle protein synthesis.
whey comprises ____% of the protein content of milk
20%
casein comprises ____% of the protein content of milk
80%
what protein source has the highest amount of leucine?
whey
3 main forms of whey
concentrate, isolate, and hydrolysate
Whey protein concentrate
-the liquid fraction of milk and is typically about 80% protein with small amounts of carbohydrates, fat, and lactose.
-contains bioactive ingredients such as beta lactoglobulin, alpha lactalbumin, and lactoferrin, which play a role in immune system function and is, therefore, less refined than the isolate form
Whey protein isolate
contains a higher portion of protein by weight (90%) and is a result of additional filtration of whey concentrate, during which the bioactive compounds, fat, and carbohydrates are removed.
Whey protein hydrolysate
contains shorter amino acid chains (peptides), which are formed by adding enzymes to either whey concentrate or isolate, purportedly enhancing digestion and absorption.
-most expensive
why does casein stimulate less muscle growth than whey?
it contains less leucine and is insoluble in acid, forming clots in the stomach acid, thereby leading to slower digestion and absorption
why does soy protein stimulate less muscle growth than whey and casein?
-lower leucine content
- fewer essential amino acids
-lower bioavailability
To maximize MPS and hypertrophy, consume four meals with _______________________ of body weight per meal of high-quality protein.
0.2 to 0.25 g/lb (0.4 to 0.55 g/kg)
A pre-bedtime protein dose of _______ grams may help maximize MPS during sleeping hours.
30 to 40
essential amino acids (EAAs) list
-Leucine
-Histidine
-Phenylalanine
-Isoleucine
-Lysine
-Threonine
-Valine
-Methionine
-Tryptophan
the consumption of EAAs has potential value for enhancing muscle protein synthesis when ___ to ____ grams are consumed before, after, or during exercise
6 to 12 grams
Consuming __ to __ grams of essential amino acids with ___ to ___ grams of leucine may maximize MPS and reduce muscle soreness.
6 to 15 grams EAAs,
1.7 to 3.5 grams leucine
