GABA Precursor Supplements UK — Calm Focus & Mood Support

What are GABA precursor supplements?

GABA is a calming neurotransmitter your brain uses to balance mental activity. Many plants — including valerian root, lemon balm, and L-theanine sources — work as GABA precursors, supporting your body's ability to produce and use GABA naturally. When GABA activity is well supported, many people report feeling calmer and more focused without feeling sedated.
