Anserine Carnosine Supplementation Suppresses The Expression Of The Inflammatory Chemokine CCL24 In Peripheral Blood Mononuclear Cells From Elderly People

This study investigated whether supplementing with anserine and carnosine - two naturally occurring amino acids found in muscle tissue - could reduce inflammation and protect memory in older adults. Researchers conducted a rigorous double-blind trial with 60 healthy elderly volunteers, giving half the group 1 gram daily of the supplement (in a 3:1 ratio) and the other half a placebo for three months.

The results showed promising benefits on two key fronts. First, the supplement significantly reduced levels of CCL24, an inflammatory protein in the blood that's associated with aging-related inflammation. This "inflammaging" process is believed to contribute to cognitive decline and various age-related diseases. Second, participants taking the supplement maintained their verbal memory better than those on placebo, particularly among people in their 60s and 70s. The researchers found a clear connection between reduced inflammation and better memory preservation.

What makes this particularly relevant for metabolic health is the growing understanding that chronic low-grade inflammation accelerates aging and increases risk for metabolic disorders like diabetes and cardiovascular disease. The fact that a simple amino acid supplement could measurably reduce inflammatory markers while protecting cognitive function suggests potential benefits for healthy aging.

From a clinical perspective, while these results are encouraging, this was a relatively small, short-term study. Patients interested in cognitive protection and healthy aging should discuss with their healthcare provider whether anserine/carnosine supplementation might fit into a comprehensive longevity-focused health plan, alongside established interventions like exercise, nutrition optimization, and metabolic health monitoring.
