Ingredient Articles

Ingredient Dosing

D-REK 90 earned a thumbs-down in this category because it does not disclose any ingredient amounts on its label making it impossible to gauge dosing effectiveness. Seventy-five (75)% of product's ingredients must be dosed within the effective range to receive a thumbs-up in this area.

This category compares a product's ingredient dosing to effective doses found in research articles and doses used in other products. When researchers study the efficacy of supplement ingredients, they use specific doses. Manufacturers should create products with ingredient doses that fall within established effective ranges.

D-REK 90 does not list ingredient amounts on its label. This makes it impossible to analyze ingredient dosing.


D-REK 90 earned a thumbs-down in this category because 52% of its claims are rated as either extremely or moderately effective. Seventy-five (75)% of a product's claims must be rated as extremely or moderately effective to receive a thumbs-up in this area.

The product’s effectiveness rating is an overall picture of how well a product does or doesn't work. Individual studies research an ingredient's effects on certain claims. For example: does creatine monohydrate increase strength, or does beta alanine improve running performance?

The Supplement Database compiles the conclusions of these studies, and based on a product's ingredient makeup, calculates how well a product does on various claims. The claims below are organized by effectiveness (extremely, moderately, ineffective).

Research Rating

D-REK 90 earned a thumbs-down in this category because its research rating is 17. A product's research rating must be at least 60 to receive a thumbs-up in this area.

A research rating of 17 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.

Nutrition Label and Ingredient Transparency

D-REK 90 earned a thumbs-down in this category because it discloses 0% 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.

D-REK 90 contains:

  • total ingredients: 16
  • ingredients with amounts listed: 0
  • ingredients without amounts listed: 16
  • percent of ingredient amounts disclosed: 0%
