What qualifies for the Casein Protein directory?
This page is for current protein products whose primary protein identity is casein, especially micellar casein. It should compare casein-specific fields rather than repeat the calorie-heavy logic of mass gainers or the meal-completeness logic of meal replacements.
The current verified set includes Optimum Nutrition Gold Standard 100% Casein, Dymatize Elite Casein, Naked Casein, Kaged Casein, Legion Casein+ and Muscle Feast Micellar Casein.
Protein per serving is the first normalized field
Optimum Nutrition currently lists 24 g protein per serving. Dymatize Elite Casein lists 25 g. Naked Casein lists 26 g. Kaged Casein lists 25 g. Legion Casein+ lists 21–22 g depending on flavor. Muscle Feast Micellar Casein lists 26–27 g depending on the current flavor/product variant.
This creates a clean casein-specific comparison: protein grams can be compared directly while preserving flavor-dependent ranges where the manufacturer varies the label.
Micellar casein identity matters more here than calorie load
Optimum Nutrition, Dymatize, Naked, Kaged, Legion and Muscle Feast all currently identify their products around micellar casein. Dymatize states that 100% of the casein in Elite Casein is micellar casein, while Kaged identifies its formula as 100% micellar casein isolate.
MenPS should therefore expose the casein form as a primary catalog field rather than borrowing mass-gainer fields such as total carbohydrate or calorie density.
Ingredient simplicity creates useful separation within casein
Naked Casein is a strong ingredient-simplicity example because the current product is positioned as a one-ingredient micellar-casein powder. Muscle Feast is also useful as a sourcing differentiator because the current product page emphasizes native-milk sourcing.
These distinctions create information gain that is specific to casein shopping and not relevant to a meal-replacement comparison.
Testing and certification should be separate attributes
Kaged currently uses Informed Sport testing/certification positioning. Legion and other brands also use third-party testing language. MenPS should record current certification or testing claims as a separate field and avoid converting them into broad efficacy or quality-superiority conclusions.
Current availability is mixed across the category
Muscle Feast Micellar Casein is current but its official page presently shows sold out. The inspected Naked Casein variant also shows sold out. Those products should remain in the directory as current identities while availability is clearly separated from product currency.
Recommended Casein-page data model
The core fields should be protein per serving, casein form, serving size, ingredient simplicity, flavor-dependent macro range, testing/certification, current availability and source-check date.
Calories and carbohydrates can remain secondary nutrition fields, but they should not become the organizing principle of this page.
How this differs from Mass Gainers and Meal Replacements
Casein products are primarily protein products. Mass gainers are primarily calorie-dense weight-gain products. Meal replacements are intended to substitute for a meal with broader nutrition coverage. Those are different user tasks even when all three products are powders.
Where a brand publishes a flavor-dependent range, the directory should preserve that range. This is especially relevant for Legion Casein+ and Muscle Feast Micellar Casein, where current product values can vary by flavor or variant.
Protein grams should always be tied to the manufacturer's current full serving. A powder that provides more protein per scoop may also use a larger scoop, and flavor variants can change both serving weight and macro values. MenPS should therefore retain serving size next to protein grams rather than ranking products on protein amount alone.
Serving normalization prevents misleading protein comparisons
Casein composition is not a performance ranking
Official manufacturer pages can verify protein amount, serving size, casein form, certification and current availability. They do not independently prove that one finished casein product produces better overnight recovery, muscle growth or satiety than another.
Current-source verification
All six inventory rows were freshly checked against current manufacturer pages during the September audit. Flavor-dependent ranges and current sold-out status should be rechecked when this directory is materially updated.
Useful follow-up questions
Is casein protein the same as a mass gainer?
No. Casein is primarily a protein category, while mass gainers are defined by high calorie and carbohydrate delivery.
Why use protein ranges for some products?
Because current labels can differ by flavor, and MenPS should preserve those ranges rather than publish a false universal value.
Does a sold-out casein product count as discontinued?
No. Current product identity and live inventory availability are separate fields.
Primary product sources used for this snapshot
Current product identity, nutrition/composition, availability and format were checked against manufacturer or brand-owned product pages. These sources support catalog facts, not independent efficacy conclusions.
