A lot of scientific evidences are pointing to L-carnosine as a very potent anti-ageing and longevity nutrient. L-carnosine is a dipeptide produced from the synergy of the amino acids alanine and histidine. The body produces its very own supply of this nutrient and they are mostly found in the brain, nerves, and skeletal muscles.
When we are younger, L-carnosine is one of our body’s most potent protections against the damage brought by free radicals such as oxidation, DNA damage, glycation, and other tissue injuries. During this time, we don’t realise how valuable this amino acid is, until such time that we produce less and less of it as part of the ageing process, and as side effect of trauma and stress.
Once L-carnosine’s protection is lost, we become more prone to cognitive decline, memory loss, loss of metabolic control, low energy, increased risk for degenerative diseases, and higher chances of having cancer. Old age means we need to have an additional supply of L-carnosine from the diet or from supplements to ensure cellular rejuvenation during the entire ageing process.
Meanwhile, maintaining healthy levels of L-carnosine accounts for numerous longevity and anti-ageing benefits. It is found in tissues with high energy demands such as the brain, heart, and muscles. L-carnosine protects these organs and helps them carry out their functions throughout the ageing process.
Carnosine exhibits multi-targeted benefits on cardiovascular health. It offers protection against ischemia, or lack of blood supply to the heart, which can immediately lead to heart attack. According to studies, L-carnosine works though its potent antioxidant activities, acid-buffering abilities, and capacity to trap transition metals that induce oxidation. Furthermore, this nutrient was shown to be very effective at combating the harmful effects of ischemia-reperfusion injury to the brain cells. Ischemia-reperfusion injury occurs when tissues have been deprived of oxygen-rich blood such as during stroke and then exposed to high-oxygen levels after restoration of blood flow.
While conventional drug treatment produces minimal benefits on the preservation and restoration of the brain’s cognitive functions, L-carnosine appears to be more promising. In Alzheimer’s disease, scientists have found that there are lower levels of L-carnosine compared to other older adults not afflicted with this type of dementia. This dipeptide can possibly protect the brain cells from amyloid plaques found in Alzheimer’s by ensuring that the brain cells get enough energy from its mitochondria.
For the muscles, high levels of L-carnosine support exercise performance and reduce fatigue. Lab studies reveal that it balances the increasing acid levels in the muscles, which contribute to pain and fatigue related to work out.
