The 'gut-brain axis describes the two-way communication between our gut and brain. Recently, this concept has been extended to factor in how our gut bacteria can affect the way we think, our behaviour, and our emotional state (1). To explore this relationship between our gut microbiome and our mood, a number of clinical trials have investigated whether probiotic supplements might have a beneficial effect on mood in healthy people. Overall, the results of these studies found a significant improvement in psychological symptoms - including stress and anxious feelings - in the people who received the probiotic supplements, compared to the people who received an inactive (placebo) supplement (2).

A recently published clinical trial found that daily supplementation for six weeks with Biome Lift™ Probiotic significantly reduced feelings of low mood and fatigue, and improved sleep quality in healthy people (3).
