Key Benefits

  • Supports relaxation and reduced tension.

  • Promotes restful, quality sleep.

  • Targets the gut-brain axis.

  • Helps manage occasional stress.

  • Clinically studied psychobiotic for wellness.

Formulated with a clinically studied psychobiotic, this advanced supplement promotes relaxation and supports deep, restful sleep.

Powered by 1714™, a unique strain of Bifidobacterium longum, it works by targeting the gut-brain axis to support stress management and mental wellbeing. Research shows that a balanced microbiome has a significant impact on mood, cognitive function, and sleep patterns. By influencing neurotransmitters and stress-related biochemical responses, this formula helps reduce mental fatigue, improve resilience, and support healthy cortisol levels.

This supplement provides a natural approach to occasional sleeplessness, helping to ease tension and enhance overall wellbeing without dependency.

Microbiome Labs formulates scientifically backed supplements designed to support digestive and immune health. Each product undergoes rigorous clinical research to ensure effectiveness, focusing on the unique benefits of Bacillus spores, a significant advancement in probiotic research. By prioritising practitioner-exclusive formulations, Microbiome Labs delivers targeted solutions that optimise gut microbiome balance and overall wellbeing.

Founded by Dr. Tom Bayne and Microbiologist Kiran Krishnan, Microbiome Labs was born from a shared commitment to innovation in gut health. Dr. Bayne’s clinical expertise and Krishnan’s research into probiotics have driven the brand’s mission to elevate industry standards and provide practitioners with high-quality, science-driven solutions.
