How Perfect Peace™ Works

Section Image

The Perfect Peace™ guild of carefully selected probiotic strains works in harmony to help your gut produce calming neurotransmitters — like serotonin and GABA — which naturally soothe the nervous system and support emotional balance. By nurturing this gut-brain dialogue, Perfect Peace™ helps ease the physical and mental tension that everyday stress can create.

These beneficial strains also help reduce disruptive byproducts in the gut that can cloud mental clarity and contribute to a sense of unease. Supporting a healthy gut lining and balanced microbiome means the body can better regulate stress responses, allowing you to feel calmer and more centered throughout the day.

What sets Perfect Peace™ apart is its targeted, science-backed blend of probiotic strains — a uniquely designed guild created to restore the gut’s role as a foundation for calm and resilience. It’s more than a probiotic; it’s a gentle, natural ally for navigating life’s stresses with greater ease.

We created Perfect Peace™ to help ease the weight that modern life places on the mind and body. Today’s world brings a constant stream of stressors — from busy schedules and digital overload to environmental pressures — all of which can quietly strain our gut-brain connection and tip us out of balance.

In our years of research, we’ve seen how deeply stress can disrupt the gut’s ability to support mood, sleep, and resilience. Perfect Peace™ was born out of a simple idea: nurture the gut as the source of calm, and the whole body feels the difference. This formula reflects our commitment to empower your health journey — restoring a sense of ease and steadiness in an often chaotic world.

Perfect Peace™ is more than just a probiotic, it’s a thoughtful breakthrough for nurturing calm and resilience through the gut-brain connection. While many probiotics aim only to add beneficial bacteria, Perfect Peace™ brings together a targeted guild of strains that actively support the production of calming neurotransmitters and protect the body from the hidden toll of everyday stress.

This multi-strain formulation not only encourages the gut to produce natural mood-balancing compounds like serotonin and GABA, but also:

  • Supports detoxification of disruptive gut byproducts that can amplify stress and cloud mental clarity.
  • Boosts short-chain fatty acids, like butyrate, which strengthen the gut lining and help regulate inflammatory pathways linked to mood imbalance.
  • Includes the amino acids tryptophan (a precursor to serotonin and melatonin), and tyrosine (a precursor to dopamine, norepinephrine, and epinephrine), supporting cognitive performance, mood, and stress response.

By restoring balance and diversity within your microbiome, Perfect Peace™ supports clearer thinking, more balanced mood, and a more restful mind. It’s not just about easing stress — it’s about transforming how your gut helps you feel calm, present, and resilient in a demanding world.

Take 2 capsules per day. We recommend taking 1 in the morning and 1 around dinner time. If you experience more daytime stress, both capsules can be taken in the morning if preferred.

Lactobacillus plantarum (TBC LP-36™):

  • Breaks down acetaldehyde, which can harm membranes, and produces butyrate to protect the gut barrier.
  • Supports serotonin and melatonin precursor production; contributing to sleep quality and scavenging free radicals.
  • Unique ability to degrade glyphosate and remove heavy metals like aluminum.

Lactobacillus rhamnosus:

  • Produces muramyl dipeptides which may support immune health and increases the production of butyrate to support a healthy gut lining.
  • It’s one of the most well-studied probiotic species known to benefit digestive health.

Bacillus subtilis (DE111® by Deerland):

  • Produces muramyl dipeptides which may support immune health and increases the production of butyrate to support a healthy gut lining.
  • It’s one of the most well-studied probiotic species known to benefit digestive health.
  • Improved mitochondrial efficiency supports stable mood, energy, and recovery from stress—central components of emotional resilience.
  • Better protein digestion, equating to better access to emotional regulatory molecules like serotonin, dopamine, and GABA.

Pediococcus acidilactici (TBC PA-68™):

  • Primarily controls pathogens by producing the bacteriocin pediocin A, known for its antiviral and anti-listerial properties.
  • May prevent inflammatory compounds from crossing the gut lining.
  • Enhances gut pH balance and short chain fatty acid production, critical for mood regulation and gut-brain axis function.

Bifidobacterium longum:

  • Offers protection against pathogens and modulates the immune system.
  • Provides essential nutrients by digesting resistant carbohydrates.
  • May alleviate the effects of acute stress, reducing oxidative stress and stimulating sleep centers in the brain.
  • Modulates the hypothalamic–pituitary–adrenal (HPA) axis; lowers stress-induced cortisol; improves emotional resilience.
  • Clinical studies from leading microbiome researchers have shown that certain strains of B. longum can help reduce feelings of anxiety and support healthy cognitive function.

Bacillus subtilis (DE111®by Deerland):

  • Enhances immune function and pathogen control
  • Helps regulate with both diarrhea and constipation by maintaining gastrointestinal health.
  • It also produces anti-inflammatory compounds, antioxidants, and other metabolites to promote overall health.

Lactobacillus reuteri (PCR07):

  • Associated with increased oxytocin production, the happy hormone.
  • Produces antimicrobial substances and converts glucose to mannitol.
  • May reduce the production of pro-inflammatory cytokines.
