Exclusion criteria
Exclusion criteria: Exclusion criteria The protein supplements used in this study are derived from peas and milk. Individuals with a nut allergy or a milk allergy are excluded for safety reasons, as intake may trigger an allergic reaction. Individuals who habitually consume only plant-based protein supplements are excluded because a pre-post comparison would not be feasible and this does not align with the study objectives.
