# Fava Bean-Derived Muscle-Focused Ingredients Nuritas Debuts Research for Its PeptiStrong By Kalin Ned | Published 2026-07-27 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/peptistrong References: [linkedin](https://www.linkedin.com/pulse/new-study-finds-peptistrong-outperforms-leucine-hmb-aging-muscle-5dtcc)  Nuritas, a biotechnology company specializing in the discovery of bioactive peptides from whole foods, has published new peer-reviewed research in the NFS Journal comparing its [fava bean-derived ingredient](https://www.trendhunter.com/trends/fava-bean-pasta), [PeptiStrong](https://www.trendhunter.com/trends/bioactive-peptide), to leucine and HMB, two well-established compounds for supporting muscle protein synthesis. [Nuritas'](https://www.trendhunter.com/trends/nutrabolt) study introduced a novel human skeletal muscle model developed by the company to capture age-related changes. The research found that PeptiStrong activated muscle-building signaling significantly more than either leucine or HMB alone, with increases in ribosomal S6 phosphorylation of nearly six-fold in young cells and over three-fold in aged cells. Critically, the research identified that PeptiStrong works through the MAPK/ERK pathway, a mechanism independent of the LAT1 transporter that leucine relies on to enter cells, and which was found to be markedly reduced in aged muscle cells.
