Amino Xtra earned a thumbs-down in this category because its research rating is 22. A product's research rating must be at least 60 to receive a thumbs-up in this area.
A research rating of 22 means there is an insufficient amount of research on the product's ingredients to ensure its 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.
Amino Xtra earned a thumbs-up in this category because its discloses 100% of its ingredient amounts. A product must disclose all ingredient amounts to receive a thumbs-up in this area.
Nutrition label transparency refers to how many ingredients are listed with amounts on the product label. Many supplement manufacturers hide ingredient amounts under the guise of great-sounding proprietary blends such as "Maximum Muscular Size Enhancer" or "Anabolic Cell Strength Matrix."
When manufacturers use proprietary blends, they can hide ingredient amounts making it difficult for consumers to know whether a product is effective.
Amino Xtra contains:
- total ingredients: 15
- ingredients with amounts listed: 15
- ingredients without amounts listed: 0
- percent of ingredient amounts disclosed: 100%
