Tier 1's (by Citadel Nutrition) ability to improve cycling sprint performance is rated as 2 out of 3. This rating means the evidence is mixed on the product's ability to deliver on this claim. While some of the evidence supports its use, other evidence does not. Using Tier 1 to improve cycling sprint performance may lead to positive results. This rating is different from the product's overall rating and is based on what peer reviewed journal articles conclude on its ability to perform this one claim. This page contains an indepth analysis on how this claim-rating was calculated.

Note: The ratings on this page only deal with Tier 1's ability to improve cycling sprint performance. To view the product's overall rating, visit the product's main page: Tier 1.

Detailed Report

The detailed report is an in-depth analysis on how Tier 1'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 Tier 1's ability to improve cycling sprint performance. The rating next to the ingredient describes the ingredient's ability to improve cycling sprint performance. These ratings are averaged together and provide the product's overall ability to deliver on the same claim.

Ingredients Improve Cycling Sprint Performance Rating
Creatine Monohydrate 2.2 out of 3
Beta Alanine 2 out of 3
Caffeine 1.8 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 cycling 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 one way or another on a product's ability to deliver on this particular claim.
