Getting started guide

For your first 28-day rotation with Good Bacteria

Welcome

Good Bacteria is the first doctor-formulated, 28-day rotating synbiotic designed to work in sync with the gut. Inspired by the diverse microbial inputs of nature, it moves beyond static, strain-specific probiotics to a dynamic, systems-based approach. Each week introduces a new formulation — clinically studied strains paired with three types of prebiotic fibers and a postbiotic — designed to expand microbial diversity, strengthen gut barrier integrity, and build resilience across the body’s systems.

What’s inside

1 daily sachet. 4 weekly rotations. Each sachet includes:

Probiotics
Probiotics are beneficial bacteria that support your gut. Each sachet delivers five probiotic strains (7–18 billion units AFU*), rotated weekly to introduce variety. The sachets include cornerstone strains with decades of published research, such as LGG® and BB-12®, along with other clinically and scientifically studied strains selected to expand microbial diversity and ecosystem support.

Prebiotics
Prebiotics feed your gut bacteria, aiding the work of probiotics. Each sachet includes three diverse fibers, fructooligosaccharides (FOS) to nourish beneficial microbes, organic acacia fiber for steady nourishment, and organic green banana flour, a slow-fermenting resistant starch for lasting support.

Postbiotics
Postbiotics are beneficial by-products and microbial components that help maintain gut barrier integrity and support gut function. Each sachet includes inactivated Limosilactobacillus reuteri, selected to contribute to a thriving gut environment.

On rotation 

Most probiotics deliver the same strains every day. Good Bacteria takes a different approach, focusing on microbial variety: four distinct blends, rotated weekly to broaden microbial inputs and support diversity — a core marker of gut health. Each blend features clinically studied strains, applied in an innovative rotation model designed to work in rhythm with your gut and strengthen ecosystem resilience. Unlike traditional probiotics built around single outcomes, Good Bacteria was created to nourish the whole gut ecosystem, because diversity is the foundation of this resilience.

Formulation and quality

Good Bacteria was developed by doctors and in partnership with leading scientists from renowned medical research institutions including Johns Hopkins, Stanford, and Oxford. Each blend is grounded in strains with over a decade of clinical research. Building on that foundation, Good Bacteria is pioneering a rotating system designed to introduce variety and promote microbial diversity in the gut ecosystem.

Every batch is manufactured in an FDA-registered facility under GMP standards, is third-party tested for purity and potency, and is made with non-GMO ingredients without fillers, artificial colorants, or added sugars.

How to take it

• Take one sachet daily.

• Mix into 8–12 oz of cool or room-temperature water, or add to your preferred beverage or food.

• Do not mix with hot food or drink, as heat may reduce probiotic integrity.

• Store in a cool, dry place.

• Complete each week’s sachets before moving to the next week’s blend.

Because Good Bacteria is free from fillers and made with diverse, high-quality fibers, it may take a little longer to dissolve. This is normal and reflects the integrity of the ingredients.

Your 28-day rhythm

Your gut thrives on rhythm. Each week builds on the last to introduce, expand, maximize, and reset microbial diversity.

Week 1 — Prime
A gentle entry point with foundational strains to help the gut ecosystem acclimate.

Week 2 — Expand
Inputs broaden, supporting digestion, immune function, and microbial diversity.

Week 3 — Peak
The highest microbial count of the cycle, designed to maximize colonization and activity.

Week 4 — Balance
A recalibration phase that helps steady your ecosystem and prepare it for the next rotation.

Note: Probiotic strains rotate weekly, while prebiotic fibers remain consistent throughout to provide a steady foundation. Minor shifts in digestion (gas, stool changes, regularity) may occur in the first one to two weeks as your gut adjusts and often settle with continued use.

How long should I stay on it?

We recommend completing at least one 28-day cycle to allow your gut to acclimate to the system. For deeper results, three months of continuous use is recommended. The system is designed for ongoing use, consistently feeding the gut ecosystem to support resilience and microbial diversity over time.

If your gut feels sensitive

• Take your sachet with your first meal.

• Drink extra water.

• Keep to simple, whole foods until your system settles.

Temporary changes in digestion (like gas or stool shifts) are common when starting probiotics and/or prebiotics. These can be a sign that your gut is adapting and usually settle within one to two weeks. If sensitivity persists or worsens, discontinue use and consult your healthcare provider.

Lifestyle that amplifies results

• Eat the rainbow. Incorporate a wide variety of colors, plants, and fibers in your diet.

• Prioritize consistent sleep and circadian rhythm.

• Practice daily movement and hydration.

• Find small daily rituals to ease stress and support balance.
