Detailed Report
The detailed report is an in-depth analysis on how NFS Pre-Workout's rating for this particular claim was calculated.
Claim Effectiveness Ratings
Each supplement product is a blend of ingredients. The database uses peer reviewed journal articles to rate the ingredients. These ratings are also used to rate how well products perform overall as well as on individual claims.
The supplement ingredients listed in table below are identified as affecting NFS Pre-Workout's ability to increase strength. The rating next to the ingredient describes the ingredient's ability to increase strength. These ratings are averaged together and provide the product's overall ability to deliver on the same claim.

Claim Research Ratings
The research rating describes how well an ingredient's ability to perform a certain claim (such as increase strength) has been researched. This rating is based on the amount of studies contained in the database on a particular ingredient and claim. Ingredient research ratings are averaged together to from the product's research rating for this specific cliam.
This rating is important because we need to know if there is enough research to make a valid conclusion on a product's worthiness. Ratings above 80 are ideal. Anything below 60 means there is not enoguh research to make a valid conclusion one way or another on a product's ability to deliver on this particular claim.
