Difficult sleeping

Taking care of your microbiota

A large body of research shows that the intestinal microbiota is controlled by circadian rhythm; this means that sleep disturbances can affect the
composition and proper balance of the microbiota, which can have significant effects on overall health.
Bacteria in the intestine can affect the quality of sleep.
Microbiota diversity is positively correlated with improved sleep efficiency and total sleep time.​
What is the link between your intestinal microbiota and quality of sleep?
Tryptophan, an essential amino acid
Among its many essential functions, the intestinal microbiota helps to digest large molecules from food and transform them into smaller molecules that will in turn be used to develop new molecules essential to our body.
This is notably the case of tryptophan, an essential amino acid present in proteins, which, once broken down by a healthy intestinal microbiota, will be assimilated to reach your brain where it can be converted into serotonin. 
In the brain, serotonin will then be transformed into melatonin, the key sleep hormone. The intestinal microbiota therefore appears to be an essential link in this chain reaction. By optimizing the bioavailability of tryptophan for our brain, the impact on the quality of sleep and well-being is direct.
