Episode notes
INSIGHT

Peptides vs. Supplements

  • Peptides are chains of amino acids, distinguished from proteins by length and FDA classification.
  • Supplements, by Congressional definition, must be naturally occurring, orally administered, and derived from food or metabolites.
INSIGHT

Precursors

  • A precursor is a starting material used to create another compound, like NMN for NAD+.
  • Supplements can be precursors, metabolized by the body into the desired compound like testosterone.
INSIGHT

Oral vs. Injectable Peptides

  • Oral peptides exist, like semaglutide (Rybelsus), but injectables offer superior bioavailability.
  • Specialized coatings and permeation enhancers improve oral absorption, but injections remain more cost-effective.
