claimAdditionally, meta-analysis results showed that L-carnosine combined with anserine or antioxidant supplementation significantly improved the MMSE score compared to placebo (pooled net change = 0.62; 95% CI 0.23, 1.01), with small statistical heterogeneity ( I 2 = 21.3%).

claimConclusions: A low strength of evidence suggests that L-carnosine supplement combined with anserine or antioxidants can slow cognitive function decline among healthy elderly or patients with probable Alzheimer's Disease or mild neurocognitive disorder.

topicAnserine Carnosine Cognition Randomized Trial
claimIntroduction: Previous research has shown that L-carnosine (β-alanyl-L-histidine) can reduce cognitive decline and improve mental health outcomes, but an updated systematic review of the effects of carnosine alone or in combination with other supplemental nutrients or bioactive compounds on these interconnected outcomes is lacking.
