Guidelines for Selecting Dietary Supplements

A
  1. Verify the ingredients are supported with solid evidence for efficacy and safety from scientific reviews, reputable organizations, and/or well-designed human studies.
  2. Determine whether ingredient forms and dosages in product formulas match evidence-based recommendations.
  3. Check if the product is independently tested to verify label accuracy. For athletes, third-party testing for banned substances is critical.
  4. Request independent research from companies that verifies the claims for their products.

46
Q

International Society of Sports Nutrition (ISSN) recommended daily protein intake

1.4 to 2.0 grams/kilograms of body weight to build and maintain muscle tissue for most exercisers; split evenly throughout the day, approximately every 3 to 4 hours

47
Q

Consumption of protein immediately (1 hour after resistance training)

A

May not enhance hypertrophy if total daily intakes are met, doing so may support recovery and subsequent training and performance

48
Q

Post-workout period

A

Post-workout period offers an opportunity to consume a high-quality protein dose to help reach daily targets, enhance MPS, and potentially benefit continuous intense training. Additionally, appetite is often diminished after intense activity and consuming a protein-rich shake may be more feasible, especially at training or competition venues.

49
Q

An essential and branched amino acid; identified as an initiator of muscle protein synthesis

A

Leucine (1.7 to 3.5 grams per dose)

50
Q

Highest concentration of Leucine

A

Whey

51
Q

Sources of Leucine

A

Whey (Most), Casein, Eggs, Soy Isolate, Peas, wheat and Brown Rice

52
Q

Sources of Whey and Casein

A

Bovine Milk (Whey is 20% of milk protein, Casein is 80%)

53
Q

Whey Protein Concentrate

A

80% Protein, small amounts of Carbohydrates, Fat and Lactose
- Beta lactoglobulin, alpha lactalbumin, and lactoferrin, which play a role in immune system function and is, therefore, less refined than the isolate form

54
Q

A

Stimulates MPS during sleeping hours

55
Q

The extent to which an ingredient, food or other substance is absorbed by the body

A

56
Q

Plant-based Protein Supplements

A

57
Q

A range of intakes for carbohydrates, protein, and fats set by the Food and Nutrition Board of the National Academy of Medicine recommended to meet the nutritional needs of most individuals and reduce risk of chronic disease.

A

Acceptable Macronutrient Distribution Range (AMDR)

58
Q

Protein Supplementation Guidelines

A

Ensure total daily intakes are met using 0.7 to 1.0 gram/pound (1.2 to 2.2 grams/kilograms). Trained athletes restricting calories may benefit from more to preserve muscle and promote fat loss.
To maximize MPS and hypertrophy, consume four meals with 0.2 to 0.25 gram/pound (0.4 to 0.55 gram/kilogram) of body weight per meal of high-quality protein.
There may be benefits to consuming a protein-rich meal/snack in the post-workout period, especially with heavy training volumes, multiple competitive events, or when helping to meet total daily protein targets depending on meal frequency.
A pre-bedtime protein dose of 30 to 40 grams may help maximize MPS during sleeping hours.
