Cognition

Psychobiotics are a scientific term for probiotics, or even prebiotics that, when consumed in sufficient amounts, may positively influence mental well-being by acting through the gut-brain axis. They’re part of a growing area of research focused on probiotics for mental health and gut-brain support, with potential effects on mood, stress response, cognition, and emotional health.

Scientists are continuing to explore how these beneficial microbes may work through mechanisms such as neurotransmitter production, gut barrier integrity, and vagus nerve signaling, making this an exciting and rapidly evolving field.

The gut-brain axis is the two-way communication network connecting the digestive system and the brain, working through the vagus nerve, the immune system, and chemical messengers, including neurotransmitters. Approximately 90% of the body's serotonin is produced in the gut, which is why gut health is increasingly understood to be connected to how we think and feel. Supporting your gut microbiome with a daily probiotic supports intestinal flora health, which is one component of this broader gut-brain system.

Your gut and brain stay in constant contact through the gut-brain axis, a bidirectional signalling network that links intestinal health to mental processes. Research in this area continues to grow, with scientists exploring how intestinal flora health may relate to cognitive well-being. Bio-K+ drinkable probiotics contribute to intestinal flora health, supporting the foundation of this connection. For daily digestive health as part of an overall wellness routine, Bio-K+ offers a range of formats to suit different needs.

Every Bio-K+ drinkable shares the same exclusive three-strain probiotic formula and contributes to intestinal flora health. The Extra drinkable line goes further by adding clinically studied functional ingredients targeting specific wellness areas. Extra drinkables also deliver 80 billion live and active bacteria guaranteed until the best-before date, compared to 50 billion in the Original line. This makes the Extra line a meaningful step up for those seeking both daily digestive support and targeted active ingredients.
