Propionate
Overview
Propionate is a short-chain fatty acid (SCFA) produced by gut bacteria through fermentation of dietary fiber. It plays important roles in reducing neuroinflammation, protecting the blood-brain barrier, and regulating neurotransmitter secretion. Propionate stimulates norepinephrine secretion and may influence dopamine regulation, making it important for neurochemical balance. ADHD groups have been shown to exhibit significantly lower levels of propionic acid.
