Carnosine, known technically as L-carnosine, is naturally manufactured in the body by combining the amino acids histidine and alanine. The highest concentrations of carnosine are found in the brain, nervous system, lens of the eyes, cardiac muscles and skeletal muscles. While some studies suggest carnosine combats the ageing process, its exact function is not known, which is why it is unclear how much should be consumed, according to Tufts Medical Center.
Although carnosine is often sold in supplement form, it is also naturally abundant in protein-rich foods, particularly animal products, such as beef and pork. While these can help keep carnosine levels healthy it is natural for the human body to experience a reduction in the substance as an individual ages.
Fish is another high-protein food rich in carnosine. Proteins, such as from fish and meat, are known to be responsible for the daily functioning of living organisms. When they are damaged it can affect how the body functions and ages, according to Anti-Aging Today.
Chicken and Eggs
Chicken and eggs are also excellent high-protein sources of carnosine.
While meat, fish and poultry are the most protein-rich sources of carnosine, it can also be found in dairy products, such as cheese and milk, as well as in supplements.
