The 99%/99.5% difference reflects GABA purity measured via HPLC non-derivative method. Higher purity is positioned for premium and pharmaceutical applications.
Non-derivative HPLC is a direct quantification method that does not require chemical derivatization of the sample. This is the gold standard for GABA quantification, avoiding conversion artifacts.
Synthetic GABA is produced via chemical synthesis; fermented GABA is produced via biological fermentation (Lactobacillus). Fermented GABA may be marketed as natural-origin.
GABA is commonly combined with L-Theanine, magnesium, and other calming ingredients. We recommend consulting with your formulation team for specific combinations.
GABA is permitted as a food supplement ingredient in the EU under Novel Food Regulation 2015/2283. Specific regulatory status depends on intended application and labeling.
GABA content is quantified via HPLC with refractive index detection (non-derivative method) per industry-standard methods.
