Whey Protein Isolate earned a thumbs-up in this category because its research rating is 80. A product's research rating must be at least 60 to receive a thumbs-up in this area.
A research rating of 80 means there is a sufficient amount of research on the product's ingredients to ensure the effectiveness rating is valid.
The research rating is a measure of how much research has been conducted on a product's ingredient makeup. Manufacturers often rely on ingredients without adequate research backing. They may do this to compete with other products that are already using poorly researched ingredients. They may also only use a very small amount of cherry-picked research as a poor justification to use certain ingredients.
The amount of research contained in the database on a product's ingredients determines its research rating. Products with higher ratings are made up of thoroughly researched ingredients.
Whey Protein Isolate earned a thumbs-up in this category because its protein content as a percent of its overall calories is 91%. A product's protein percent of calories must be within 10% of all protein supplements contained in the database. This value is currently 72%.
The protein content as a percent of overall calories describes how many of a product's calories come from protein. Values closer to 100% indicate the product is made up mostly of protein. Lowers values indicate the product contains more fats, carbohydrates, and sugars. Ideally, protein supplements should contain a relatively high amount of protein rather than other calories.
Whey Protein Isolate earned a thumbs-up in this category because its protein content as a percent of its serving size is 81%. A product's protein percent of serving size must be within 10% of all protein supplements contained in the database. This value is currently 67%.
The protein content as a percent of serving size describes how much of a product's serving weight is protein. Values closer to 100% indicate the majority of a serving is protein. Lower values indicate the product is filled with non-protein and/or non-calorie ingredients to beef up its serving size.
Whey Protein Isolate earned a thumbs-down in this category because it discloses 60% of its protein amounts. A product must disclose all protein amounts to receive a thumbs-up in this area.
Nutrition label transparency refers to how many of a product's protein types are included on the label with amounts. This is an issue when a product contains more than one type of protein, without listing amounts for each.
Whey Protein Isolate contains:
- total ingredients: 2
- ingredients with amounts listed: 0
- ingredients without amounts listed: 2
- percent of ingredient amounts disclosed: 60%
Whey Protein Isolate earned a thumbs-up in this category because it discloses 100% of its fat content. A product must disclose all fat types and amounts on its product label to receive a thumbs-up in this area.
Protein supplements sometimes contain fat and many manufacturers do not disclose the type or amount of fat included in their product. There are three main types of fat: saturated, trans, and unsaturated fats. Generally, unsaturated fats are healthy while trans fats have been deemed dangerous to overall health. Unfortunately, deciding to stay away from trans fats is difficult if a manufacturer does not disclose the breakdown of fats contained in its products. In many jurisdictions, listing trans fat on the nutrition label is mandatory.
The label below was generated from the information contained in the database about the product's ingredients and amounts. Actual product labels may differ in appearance.
