The Supplement
Audit
We analyze labels. We ignore likes. A objective index for the serious Dutch athlete.
Categorical
Breakdowns
Our indexing methodology prioritizes nutrient density and specific performance biomarkers over marketing narrative.
Whey Isolate
Fast-digesting protein high in Leucine. Optimal for immediate post-training elevation of muscle protein synthesis.
Casein
Slow-release protein source. Provides sustained amino acid delivery during sleep or long fasts.
EAA Blends
Essential Amino Acids required for muscle repair that the body cannot synthesize autonomously.
Creatine Monohydrate
The most researched ergogenic aid. Facilitates ATP regeneration for high-intensity, short-duration power output.
Caffeine
Central nervous system stimulant. Extends time to exhaustion and enhances perceived exertion thresholds.
Beta-Alanine
Intracellular buffer that helps manage muscular pH levels during prolonged high-intensity effort.
Vitamin D3
Critical for skeletal integrity and immune function, especially relevant for indoor training during Dutch winters.
Omega-3 Fatty Acids
Supports joint health and cardiovascular efficiency through effective inflammatory response management.
Magnesium
Essential mineral involved in muscle relaxation and neuro-muscular transmission.

01. Research Phase
Our team cross-references metabolic research against European food safety standards. We ignore marketing claims and focus on raw ingredient efficacy.
02. Dosage Math
All calculations are based on sedentary basal metabolic rates plus training activity multipliers. We calculate functional minimums for optimal performance.
03. Verification
Content is checked for clarity, neutrality, and practical applicability. If an ingredient has no clinical significance, it is flagged as anecdotal.
