Polylysine (Poly-lysine, abbreviated as ε-PL) is a natural biopolymer (polypeptide) composed of lysine monomers linked by peptide bonds. It is not a chemically synthesized substance but is produced through the fermentation of specific microorganisms (such as Streptomyces albulus), belonging to bioengineering technology products and is eco-friendly and safe.

What happens to orally supplemented GABA in the blood after it enters the human body? Existing pharmacokinetic studies show that oral γ-aminobutyric acid (GABA) exhibits the following characteristics in healthy humans: rapid absorption, mild metabolism, fast clearance with no significant accumulation tendency, and plasma GABA levels after oral administration are not affected by sex, diet, exercise, or circadian rhythm. This indicates that the dynamic changes of oral GABA in the body are relatively stable and minimally influenced by external factors.

Disclaimer: This interpretation is strictly based on public data from the original literature. Conclusions reflect only findings in mouse models and do not constitute medical or product efficacy claims. The safety of GABA as a dietary ingredient is supported by multiple studies; its application as a sports supplement requires consideration of individual differences and professional guidance.
