Quick Answer
L-Lysine Exercise Recovery Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Plasma insulin concentrations increased following protein ingestion and were higher in the protein groups compared with PLA (time × treatment effect:< 0.001).
Key Takeaways
- 01Plasma insulin concentrations increased following protein ingestion and were higher in the protein groups compared with PLA (time × treatment effect:< 0.001). [van Lieshout Glenn AA (2025)]
- 02In contrast, when lysine was excluded from the EAAs, plasma EAA-Lys concentrations for HIGH-GLYC were slightly higher compared with LOW-GLYC between 90 and 120 min (≤ 0.018 for both timepoints,E), but this did not result in a different iAUC between the protein treatments over the full postprandial period (= 1.00,F). [van Lieshout Glenn AA (2025)]
- 03As a result, peak lysine concentrations were 28% lower following ingestion of HIGH-GLYC compared with LOW-GLYC (191 ± 23 vs 266 ± 47 μmol · L, respectively,< 0.001). [van Lieshout Glenn AA (2025)]

Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
