It’s long been known that the gut and the brain are linked. The two organs are connected both physically and biochemically and the communication system between your gut and brain is called the gut-brain axis.

Probiotics, also known as the “good bacteria” in yogurt, may benefit mental health and capabilities. This “good” bacteria, directly related to gut health, may help to modulate stress, emotional behaviour and brain biochemistry. Research in one particular study has shown that patients with a history of brain injury, showed improvements in their cognitive functions after consuming yogurt with probiotics.
