Gelatin

Supplement

Heat-denatured collagen used as food and as a protein supplement. Product composition and peptide distribution vary; human studies measure amino-acid availability or downstream collagen-synthesis markers rather than a unitary circulating gelatin concentration.

Pharmacokinetic model

A route-level PK model for gelatin is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.

  1. Vitamin C-enriched gelatin supplementation before intermittent activity augments collagen synthesis Shaw G, Lee-Barthel A, Ross ML, Wang B, Baar K · American Journal of Clinical Nutrition, 2017 DOI

    Randomized double-blind crossover experiment in eight healthy men compared 5 g, 15 g, and placebo before exercise and assessed circulating amino acids plus ex vivo ligament markers. The very small mechanistic study does…

  2. The effects of collagen peptide supplementation on body composition, collagen synthesis, and recovery from joint injury and exercise: a systematic review Khatri M, Naughton RJ, Clifford T, Harper LD, Corr L · Amino Acids, 2021 DOI

    Systematic review covered heterogeneous collagen-peptide products rather than gelatin alone. It reported possible musculoskeletal signals but emphasized variable formulations, outcomes, and study quality.
