Methodology

Pello Score™

100-point scaleVersion 1.0 · updated Aug 5, 2026

One question: how good is this product, really? Not its marketing, packaging or endorsements. Every product is scored with the same published formula, and no brand can pay to change its score.

The five pillars

Quality and quantity of evidence behind the ingredients

  • Percentage of ingredients rated Proven vs Likely vs Disputed
  • Dose transparency — are amounts clearly disclosed?
  • Presence of flagged ingredients (artificial sweeteners, seed oils etc.)
  • Independent lab testing for banned substances

Score labels

Excellent · Strong across all pillars — highly recommended

Category adjustment

Value is compared within a category: a gel against other gels, never against protein powder. The other pillars use one scale for every product, so typical scores differ by category (hydration products tend to score higher than probiotics, for example), and scores compare most fairly within one.

Principles

  • No brand can pay to influence their Pello Score
  • The full methodology is published and transparent
  • GI comfort is given special weight as it is uniquely critical for endurance athletes
  • Scores are recalculated when new reviews or formula changes occur
