ADVICE

Compare Collagen Against Equivalent Protein

  • Compare collagen peptides against matched protein controls before assuming unique benefits.
  • Prefer trials that match grams and amino-acid content to isolate peptide-specific effects.
ANECDOTE

  • A listener reported major joint pain relief and faster recovery after starting collagen supplementation.
  • Nicolas Verhoeven noted anecdotes can precede but not replace rigorous evidence.
INSIGHT

  • Higher ketones in humans can therefore reflect a compensatory liver response, not necessarily causation of damage.
