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 Tier 1 Plus's ability to improve sprint performance. The rating next to the ingredient describes the ingredient's ability to improve sprint performance. These ratings are averaged together and provide the product's overall ability to deliver on the same claim.

Ingredients Improve Sprint Performance Rating
Creatine Monohydrate 2.1 out of 3
Beta Alanine 1.9 out of 3
Caffeine 2 out of 3
Product's Claim Effectiveness Rating 2 out of 3

Claim Research Ratings

The research rating describes how well an ingredient's ability to perform a certain claim (such as improve sprint performance) 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 on way or another on a product's ability to deliver on this particular claim.
