Effectiveness Rating for Whey Protein's Ability to Increase Protein Synthesis

The effectiveness rating is a measure of how well whey protein is able to increase protein synthesis. The overall rating for this claim is 3 out of 3. The research shows the supplement's ability to deliver on this particular claim is warranted. Using Whey Protein to increase protein synthesis will most likely lead to positive results.

Confidence Rating for Whey Protein's Ability to Increase Protein Synthesis

The confidence rating is a mesure of how valid the effectiveness rating is. This rating is based on how many studies are included in the database on this topic.

There are 4 studies in the database on whey protein; the confidence rating is 80. A score above 80 means the effectiveness rating for this supplement is reliable. A score under 80 means there is insufficient evidence to ensure a reliable effectiveness rating.

Title of Study
Ingestion of casein and whey proteins result in muscle anabolism after resistance exercise
The response of muscle protein synthesis following whole‐body resistance exercise is greater following 40 g than 20 g of ingested whey protein
Minimal whey protein with carbohydrate stimulates muscle protein synthesis following resistance exercise in trained young men.
Ingestion of whey hydrolysate, casein, or soy protein isolate: effects on mixed muscle protein synthesis at rest and following resistance exercise in young men
