Supports a balanced gut-brain connection for a calmer, more resilient mind.

Stress, tension, and anxiousness are often amplified by the gut–brain connection. When excitatory signals like glutamate and aspartate are too high, or when the body can’t produce enough calming neurotransmitters like serotonin, the result can be restlessness, irritability, and difficulty coping with daily stress. Perfect Peace® was designed to help restore balance to this delicate system.

Our six-strain probiotic team works together with prebiotic FOS and the amino acids tryptophan and tyrosine to produce metabolites that calm the nervous system and support emotional resilience. The formula encourages natural serotonin and dopamine production, reduces excess excitatory compounds, and gently activates the body’s opiate receptors—all of which help promote relaxation and a greater sense of peace.

At the same time, Perfect Peace® boosts short-chain fatty acids (SCFAs) like butyrate, which protect and strengthen the gut lining, reduce inflammation, and influence signaling between the gut and the brain. Together, these actions create a healthier, more stable microbiome environment that supports calm, focus, and clarity

Our formulas are balanced for sustained action, which means they work longer and are stronger. Customers have reported feeling steady and calm even during stressful situations like disrupted airline travel—real results that show how much impact the right probiotic blend can have on peace of mind. Restore balance in your gut and rediscover your best self with Perfect Peace®.

Here are some of the key strains and benefits that differentiate our formula:

Lactobacillus plantarum (TBC LP-36™): Shown through genetic analysis to produce metabolites that reduce excitatory compounds like glutamate. Also generates butyrate to protect the gut lining, sequesters toxins, and supports antioxidant production.

Lactobacillus rhamnosus: One of the most researched probiotics for mood balance. Known to reduce anxiety-like behaviors in studies and support GABA production, a neurotransmitter that helps calm the nervous system.

Pediococcus acidilactici (TBC PA-68™): Produces protective bacteriocins that help control pathogens and inflammation. Supports immune balance while contributing to the production of calming metabolites.

Bifidobacterium longum: Improves stress resilience by reducing oxidative stress and modulating the HPA (hypothalamic–pituitary–adrenal) axis. Associated with improved mood and sleep quality.

Bacillus subtilis (DE111®): A spore-forming probiotic that helps regulate the gut environment. Supports healthy digestion, immune balance, and antioxidant activity, creating stability for other strains to thrive.

Lactobacillus reuteri (PCR07): Converts glucose into beneficial compounds and produces antimicrobial substances. Linked to increased oxytocin production, improved stress response, and accelerated healing.
