True Biome delivers triple-action gut care - combining prebiotics, postbiotics and gut barrier support in one harmonious blend designed to feed, repair and protect your gut.
Your gut isn’t just a digestive organ - it’s a dynamic ecosystem, nurtured by nutrients, influenced by daily habits, and challenged by the demands of modern living. True Biome is carefully crafted with PHGG fibre to feed beneficial microbes, L-glutamine - an amino acid and building block of the gut lining - and postbiotics to support your unique microbial balance.
+ A balanced gut supports whole-body health.
+ Gut diversity is key for microbial balance and harmony.
+ The gut lining acts as your body’s internal protective barrier.
+ Prebiotics feed beneficial microbes, helping them thrive.
+ PHGG is a gentle, effective prebiotic fibre for daily gut support.
+ Postbiotics are natural compounds produced by microbes that help maintain balance.
How to Use

Ingredients explained
PHGG
PHGG is a soluble prebiotic fibre. Prebiotics feed beneficial gut bacteria and encourage the production of short-chain fatty acids - compounds that help maintain a healthy gut environment and support gut barrier function. PHGG is particularly noteworthy for being low-FODMAP and well tolerated, even by those with sensitive digestion.
Prebiotic fibre may help improve stool form and reduce bloating, all contributing to a more stable environment for microbial balance. With over 100 clinical studies supporting its efficacy, PHGG reflects our belief in long-term nourishment - feeding the inner terrain and encouraging balance over time.
L-Glutamine
L-glutamine is a conditionally essential amino acid found naturally in the body, especially in the gut lining. It serves as a key fuel source for intestinal cells and becomes particularly important during times of physical stress, intense exercise, or when the body is run down - moments when the gut may need extra support.
Naturally present in many protein-rich foods, l-glutamine plays a role in various cellular processes and is a well-studied nutrient in the context of gut function and resilience.
Lactobacillus plantarum L-137 HK
The cutting-edge, heat-treated postbiotic strain Lactobacillus plantarum HK L-137 is derived from the traditional Japanese fermented food narezushi. Postbiotics are essentially the benefical end products usually created by the probiotics in gut.
Unlike live probiotics, HK L-137 is shelf-stable, does not require refrigeration, and is well tolerated by those with microbiome sensitivity. It has been widely studied in clinical research exploring its role in supporting immune function, skin hydration, and microbial balance. This gentle yet powerful postbiotic complements True Biome’s inclusive approach to long-term gut care.
True Collagen provides easily digestible, highly absorbable and clinically researched Type I hydrolysed bovine collagen peptides that blend effortlessly into both hot and cold drinks.
Turns out, your gut impacts way more than digestion! Such an impressive formula and one I take daily. Prebiotics, postbiotics and gut barrier support working together.

A closer look
Tend to your inner terrain
Like any of nature's sacred ecosystems, your gut depends on rich diversity and tender care. We feed the soil, protect the roots, and honour nature’s ancient wisdom. True Biome works to gently restore balance to your inner terrain - so your whole body can thrive from the ground up.
Harmony starts within
Your gut is not just digestion - it’s the epicentre of your whole body’s health. It's the home to your immune system, brain connection, hormonal rhythm and even the clarity of your skin. True Biome is designed to nourish this inner centre, creating harmony that flows outward, supporting every part of you with quiet, powerful care.
From stripped soil to fertile ground
A thriving gut is a fertile landscape, alive with vibrant diversity and deep resilience. Yet modern life - with its stress, processed foods, and unseen toxins -can strip this richness, leaving the soil bare. True Biome invites daily care, working to cleanse the weeds, rebuild the richness and restore balance to your inner terrain.
Remembering the roots
Long before modern science caught up, ancient wisdom knew the gut as the source of strength. Ayurveda called it agni, the fire of life. Traditional Chinese Medicine recognised the gut-spleen is central to Qi (life energy). Hippocrates declared all disease begins there. True Biome honours this timeless truth - restoring balance at the root, where wellbeing has always begun.
Rethinking gut health
True Biome takes a new approach to gut health with three potent allies - prebiotics, postbiotics, and amino acids to feed, repair, and protect. A refined, effective formula that supports what’s already within - nourishing your gut microbiome by restoring balance, building resilience, and supporting whole-body health from the inside out.
True Biome: The Next Chapter in Gut Health Science
True Biome is a formula designed not as a quick fix, but as a quiet, daily ritual tending to the ecosystem within, the way we would tend soil. A daily reminder that we are ecosystems, inseparable from the natural world around us.
Found in foods such as yoghurt and Kefir, probiotics are live bacteria that help support the gut by increasing the number of helpful microbes. There are many different strains of probiotics, and to avoid disrupting the gut's delicate balance, both the strain and the dose need to be well matched to your individual needs. Instead of adding live bacteria, True Biome uses a dead strain of postbiotics, which has a proven effect on the body and does not need to be refrigerated. We also add prebiotics and amino acids. Together, these nourish the beneficial microbes you already have, supporting gut resilience without the complexity of selecting probiotic strains. *If your healthcare provider has recommended a specific probiotic or you have particular concerns, we always encourage you to work closely with them to find the best solution for you.
CAN I ADD THIS TO HOT DRINKS AS WELL AS COLD?
Yes, all of these ingredients are heat stable so you can enjoy True Biome in a hot or cold drink. Simply add 6g to a drink of your choice.
ARE THERE ANY SIDE EFFECTS?
True Biome is designed to be safe, gentle, and well tolerated by most people. If you have any concerns or underlying health conditions, we recommend consulting with a healthcare professional before adding any new supplement to your routine.
WHAT IS THE BEST TIME TO TAKE TRUE BIOME?
There isn’t a specific ‘ideal’ time to take True Biome supported by strong evidence. The key is to take it consistently every day to ensure your body receives steady support. We recommend choosing a time that fits naturally into your daily routine - whether that’s morning, afternoon, or evening - and pairing it with a regular habit like breakfast. This helps make taking True Biome an easy and consistent part of your day. Consistency is what matters most for maximising the benefits of True Biome and supporting your gut health over time.
CAN I TAKE TRUE BIOME WITH OTHER PRODUCTS OR SUPPLEMENTS?
Yes, absolutely! True Biome can be enjoyed alongside any of our products. It pairs beautifully with True or Wild Collagen and True Omegas+ to create a complete gut care ritual. Collagen within the body supports the integrity and repair of your gut lining and connective tissue, while True Omegas+ provides essential fatty acids that help promote overall gut and immune health. Our products are designed to work synergistically to nurture your digestive system and support whole-body health.
CAN I TAKE TRUE BIOME IF I AM PREGNANT OR BREASTFEEDING?
While the ingredients in True Biome are generally well tolerated, they haven’t been specifically studied for use during pregnancy or breastfeeding. As a precaution, we recommend speaking with your healthcare professional before introducing any new supplements during this time.
I TAKE MEDICATIONS, CAN I TAKE TRUE BIOME ALONGSIDE?
If you are taking medications, we recommend speaking with your healthcare provider before adding any new supplement to your routine, to ensure it’s appropriate for your individual needs. True Biome is formulated to be gentle and generally well tolerated. However, because it contains PHGG (a prebiotic fibre), we advise taking it at least 1–2 hours away from medications where possible, as fibre can sometimes affect absorption. Always follow professional guidance for your specific circumstances.
When will I receive my True Biome order?
We aim to deliver UK orders within 3-5 working days. Once it has been dispatched, we’ll email you a tracking code so that you can track your ritual's journey from our door to yours. Deliveries outside the UK may vary.
