Carnosine is a protein building block that is naturally produced in the body. It is concentrated in muscles when they work, and it is also found in the heart, brain, and many other parts of the body.

How it works

Carnosine is important for many normal bodily functions, including proper function and development of muscles, heart, liver, kidneys, brain, and many other organs. There is some interest in using carnosine to prevent aging as it appears to interfere with certain chemicals that may play a role in the aging process.


Carnosine is used to prevent aging and prevent diabetes complications such as nerve damage, visual impairment (cataracts), and kidney problems.


Carnosine is safe to use.

Carnosine supplementation may protect the brain from proteins known to cause Alzheimer’s and other forms of memory loss and dementia.
Special precautions and warnings:
Pregnancy and breastfeeding: There is insufficient information about the safety of taking carnosine if you are pregnant or breastfeeding. Taking carnosine can lower blood pressure in people with low blood pressure.


Since most people, including non-vegetarians, consume very little carnosine in their diet, experts recommend at least 1000 mg per day. This dose should be sufficient to maintain optimal levels in the body.
