True Biome: The Future of Microbiome Health

At Ancient + Brave, our formulations often begin with a question: What do we truly need to stay resilient in today’s world?

Despite the explosion of gut health products on the market, many Americans are still struggling with poor digestive health, bloating, brain fog, fatigue, or simply feeling out of rhythm. Which made us ask: what’s missing?

Through a deeper understanding of gut health and what the gut influences, we set out to create True Biome, our postbiotic-powered gut health support ritual. 

How the Gut Impacts Whole-Body Health 

When it comes to whole-body health, the gut is the epicenter where immunity, metabolism, mood, and energy all intersect.

It’s where nutrients are absorbed, hormones are signalled, microbes train the immune system, and messages travel along the gut–brain axis to shape how we feel and function each day. 

Yet, few Americans realize that the gut is far from being just a digestive organ; from skin health to hormones to mood, the gut influences almost every system in the body.

Why Gut Health Matters More for Modern Lifestyles

Even when we’re doing ‘everything right’, today’s world makes it hard to maintain integrity in the gut.

• Stress hormones change how our gut moves and absorbs. 

• Disrupted sleep unsettles the circadian rhythms that govern digestion and repair.

• Some medications may chip away at microbial diversity. 

• Pollutants, microplastics, and chemicals add further challenges 

As well, certain aspects of our diets, such as processed foods and additives, can feed microbiome imbalance rather than harmony.

The result? The gut barrier becomes disrupted, and “leaky gut” can occur. This is when inflammatory compounds escape into circulation, driving fatigue, brain fog, low mood, immune dysregulation, and skin issues.

This is why gut health matters now more than ever. Because in a world where the odds are stacked against balance, the gut becomes both the most vulnerable system and the most powerful place to begin restoring health.

Introducing True Biome: Advanced Next Generation Gut Health Science

Protecting and repairing the gut barrier is increasingly being recognized as one of the most essential steps in whole-body health.

That’s where True Biome comes in. At Ancient + Brave, we believe that the future of gut health isn’t just about adding microbes; it’s about creating the right environment for them to flourish and helping the entire gut ecosystem stay resilient in the face of modern-day stressors. 

That means:

• strengthening the gut barrier

• restoring balance to the ecosystem

• supporting the intricate cross-talk between microbes, immune cells, and the nervous system

We’ll explore the ingredients behind this revolutionary gut health supplement in more detail in the next section. If you’re short on time, here’s a quick-look at some of the key features and benefits that help make True Biome your go-to ritual for gut health support.

• Beyond Probiotics. Triple-action gut care - combining prebiotics, postbiotics and gut barrier support in one 

• Barrier First. L-glutamine helps support gut lining integrity**

• Radical Simplicity. Three science-backed ingredients. Nothing more, nothing less.

• IBS-Friendly. Gentle, low-FODMAP, suitable for even the most sensitive guts.+

• 360° Benefits. The gut is not an island. When supported, its influence ripples outwards.

Postbiotic Precision: What Makes True Biome different

At the heart of True Biome is the recognition that gut health science has shifted. 

For years, the focus was on probiotics, adding more strains, more diversity, more “good bugs.”  But the new frontier is stable, safe and effective postbiotics.

Among them, Lactobacillus plantarum HK L-137 stands out. One of the most researched postbiotics in the world, clinical studies show it can:

+ Regulate immune responses**
+ Bring balance to inflammation**
+ Strengthen the gut barrier**
+ Even support collagen production**

But postbiotics don’t work in silo. Prebiotic fibers remain a foundational fuel for beneficial bacteria, a fertilizer that encourages the production of health-supporting short-chain fatty acids like butyrate.

That’s why in True Biome, we’ve combined Lactobacillus plantarum HK L-137 with PHGG (Partially Hydrolyzed Guar Gum), a low-FODMAP, clinically validated prebiotic fiber that gently fuels beneficial microbes, reduces bloating, and supports regularity.** A quiet, gentle hero, backed by over 100 clinical studies.

Completing the trio is L-Glutamine, the amino acid that fuels intestinal cells and helps maintain the tight junctions of the gut barrier.** This impacts factors related to “leaky gut,” especially under stress, one of the defining challenges of modern living.

This is a 360° ecosystem approach to gut health that works gently, for even the most sensitive guts, in harmony with the body. No excess, no noise, just three powerful, proven ingredients, each chosen intentionally to reflect the evolving science in this space.

Gut Health Is a Lifestyle, Not a Quick Fix

While this new era of gut health is something to be celebrated, it remains important to note that no powder can outpace poor habits. 

Gut health begins with how we live — the diversity of plants on our plate, the way we slow down to eat, how we regulate stress, the depth of our sleep and the time we spend moving and connecting in nature. These are the foundations no supplement can replace.

True Biome is not a quick-fix gut health supplement - it is a tool to help protect and support your inner terrain in the face of modern life.+ This is not just about digestion. This is about restoring the center of your health. We can’t wait for you to try it!

FREQUENTLY ASKED QUESTIONS

What is True Biome?             

A gut health supplement designed to be intentionally simple. True Biome contains three effective, functional ingredients. Each one is backed by research and was chosen because of its ability nourish beneficial gut microbes, support the gut lining, and help support immune balance without relying on live probiotic strains.+ 

Why doesn’t True Biome contain probiotics?     

You won’t find any probiotics in this intelligent gut-care formula. Your gut already contains trillions of microbes, and the wrong probiotic strains or doses can risk discomfort. Instead, True Biome focuses on prebiotics, gut lining support, and using a well-researched postbiotic to help create the conditions for a balanced, resilient gut.*

Can I take True Biome daily? Can it be taken with probiotics?

Yes. True Biome is designed to pair well with probiotic foods or supplements. It doesn’t compete with probiotic strains; instead, it helps nourish the gut environment and support the lining where microbes live.+

The ingredients in True Biome are commonly used for daily gut and immune support and are generally well-tolerated.+ Start with a smaller amount and increase to the recommended dose slowly if you have a sensitive gut.

Who is True Biome for? Are there any contraindications to taking it?

True Biome is a great gut supplement choice for those seeking to gently support their gut health daily. Thoughtfully created to be suitable for those with sensitive digestion.+ True Biome was formulated with SIBO-sensitive individuals in mind. PHGG is a low-FODMAP prebiotic shown in research to be generally well tolerated, even for sensitive digestion.** However, everyone with SIBO has different triggers, so it's important to start slowly and check in with your practitioner if you have concerns.

While the ingredients in True Biome are widely used, those who are pregnant or breastfeeding have unique nutrient needs. We recommend checking with your healthcare provider to ensure it’s right for you during these seasons.

What can True Biome help with? How long does it take to feel a difference?

Many people take PHGG and L-glutamine to support digestive comfort, regularity, and gut lining integrity - areas that can influence sluggish digestion and bloating. Individual responses vary, but research suggests that PHGG may help support balanced digestion over time.**

In addition, True Biome contains HK L-137, which is one of the most researched postbiotics for immune support.*** This helps the body maintain balance - not overstimulation- which is important for everyday wellbeing.*

Gut support is gradual. Some people notice improvements in digestive comfort within 1-2 weeks, while others feel changes over several weeks as the gut lining and microbiome adapt.+

What are postbiotics, and how do they differ from probiotics?

A postbiotic is a stable, safe and effective beneficial compound created by bacteria. Unlike probiotics, they aren’t live organisms. They’re heat-killed yet remain biologically active and communicate with the body in meaningful ways, even though no longer alive.

True Biome uses HK L-137, a clinically researched postbiotic that helps support immune balance and a healthy gut environment.***

Because the ingredients are stable, True Biome doesn’t require refrigeration, which makes it easy-to-use, take on the go, and incorporate daily.*
