Antioxidant and neuroprotective effects of carnosine: therapeutic implications in neurodegenerative disease
Rather than testing one condition, this review walks through the brain diseases where carnosine has been studied — Alzheimer's, Parkinson's, ALS and Huntington's — and asks how close each body of evidence is to clinical use. The common thread is oxidative stress and metal-ion damage in neurons, two things carnosine is chemically suited to blunt.
Key takeaway
Carnosine's antioxidant and metal-binding chemistry is biologically plausible across several neurodegenerative diseases, but the human evidence is still early and varies condition by condition.
