Curated, not stocked.
ION's Gut + Microbiome earned its place here because it targets a specific mechanism — tight junction support — rather than making broad digestive promises. Terrahydrite is an ingredient class with a growing body of interest in functional medicine, and the minimal formulation means fewer variables when building a layered gut protocol. We recommend it as a foundation supplement, particularly for patients whose blood work or symptom history points to gut barrier involvement.
About this product
Gut + Microbiome
ION Gut + Microbiome is a liquid supplement built around Terrahydrite, a proprietary mineral compound developed by ION Intelligence of Nature. Terrahydrite is a humic acid-derived substance, and this class of molecule is studied for its potential to support the integrity of tight junctions — the protein structures that line the gut wall and regulate what passes into the bloodstream. A compromised gut lining is increasingly linked in the research literature to systemic inflammation, digestive discomfort, and immune dysregulation, making barrier support a clinically relevant target.
This supplement suits people who experience digestive sensitivity, bloating, or who have been advised to address gut permeability following food intolerance testing or functional medicine assessment. It may also appeal to those supporting a microbiome-focused protocol, where maintaining a stable mucosal environment is considered a foundation step before introducing probiotics or dietary changes.
ION's formulation is notably simple: the active ingredient list is short, with Terrahydrite as the sole functional component. There are no added probiotics, prebiotics, or digestive enzymes, which means it serves a specific and defined role rather than attempting to cover the whole digestive category. That specificity is part of why it sits well alongside other protocols rather than duplicating them. The liquid format allows for flexible dosing and may be preferred by those who find capsule supplements difficult to tolerate.

How to use
Take 1 teaspoon three times daily. It can be taken straight or stirred into water. Check the packaging for guidance on whether to take it with or away from food, as timing relative to meals may affect its interaction with the gut lining.

Common questions
Frequently asked
What exactly is Terrahydrite and how does it work?
Terrahydrite is ION's proprietary mineral compound derived from humic acid, a substance found in ancient soil and decomposed organic matter. Humic acid-derived molecules are studied for their potential to interact with tight junction proteins in the gut lining, which are the gatekeepers that determine what passes from the digestive tract into the body. The idea is to support the structural integrity of that barrier rather than to directly alter the microbial population.
How is this different from a probiotic or prebiotic?
Probiotics introduce live bacteria; prebiotics feed existing bacteria. ION Gut + Microbiome does neither — it focuses on the physical environment of the gut wall itself. Many practitioners use it alongside probiotics, treating it as a foundation step to help ensure the gut lining is in good condition before adding microbial support.
How long before I notice a difference?
Gut barrier support supplements generally require consistent use over several weeks before meaningful change is measurable. Individual responses vary considerably depending on diet, stress, and baseline gut health. Tracking symptoms in a simple diary can help you identify any shift over a four to eight week period.
Is this suitable for people with food intolerances or a sensitive gut?
The liquid format and minimal ingredient list make it generally well-tolerated, and it is often used specifically in the context of digestive sensitivity. However, if you have a diagnosed gastrointestinal condition or take medication that affects gut motility or absorption, speak to your GP or prescribing clinician before starting.
Can I take this alongside other supplements or medications?
Because Terrahydrite is a mineral-based compound, there is a theoretical consideration around timing with medications that rely on precise gut absorption — for example, thyroid medication or certain antibiotics. As a precaution, space it away from any critical medications by at least an hour, and confirm with your prescribing doctor if you are managing a chronic condition.
