What is Carnosine?
Carnosine is a naturally occurring dipeptide made from beta-alanine and L-histidine that is abundant in muscle and present in the brain. In cognition research it is studied for antioxidant, anti-glycation, and neuroprotective effects that can indirectly support neurotransmission and mental performance.
Key Benefits & Mechanisms
antioxidant support
working memory support
neuroprotection
fatigue resistance
Research Summary
Human and animal studies suggest carnosine can support cognition under oxidative or metabolic stress, especially where neuronal resilience is a target. Its main interest in the literature is not as a direct stimulant, but as a brain-protective peptide that may help preserve synaptic function.
