Developed, produced and tested in our own laboratory in Belgium.
The full range
Built modularly around co-metabolism: you are the host of your micro-organisms.
Anyone looking for a food supplement or sports nutrition today finds thousands of products that often contain the same ingredients. Yet the greatest added value rarely arises from one separate substance, but from the way ingredients work together and how they fit the body’s biology.
At My Key Nutrients we therefore start not from an ingredient, but from a biological system.
Our product families are developed on the basis of the insights from My InnerSelfie and the principle of co-metabolism: the constant cooperation between the host, the microbiome, food and lifestyle. Each family has its own role within that ecosystem. That is why the families complement rather than replace each other.
A supplement that stays in the cupboard does nothing. That is why Bottle-on-the-Go is built around the only moment that really counts: that one instant when you fill your bottle. One scoop, cold water, ten seconds of shaking — done.
Beneath that simplicity lies the idea the whole of My Key Nutrients rests on. You are the host of your own ecosystem — Home Of Symbiotic Teams, the house in which thousands of billions of micro-organisms live. What you drink you never process alone; you do it together with them. We call that interplay co-metabolism, and every Bottle-on-the-Go feeds both sides of it: your cells and your microbiome.
That is why every formula carries a digestive or prebiotic base — plant enzymes such as papain and bromelain, or fibres such as inulin and acacia fibre. And that is why there is not a gram of bulk filler in it: the serving weight is the sum of the active constituents, not of cheap padding.
The sixteen formulas are modules. You stack them or rotate them, and so gradually cover the various gut-organ axes. Every batch is tested according to Triple T (Trace · Test · Trust) and screened for prohibited substances. Made in Belgium, from formula to jar.
Focus: Daily support, drinkable hydration and microbiome vectors, gut-organ axes.
Most supplements put one substance centre stage and hope it does its job. X-Fusion starts from the opposite: in your body nothing works alone. A collagen peptide needs vitamin C, a mitochondrial cofactor needs a second cofactor, and everything you swallow has to pass through your gut first.
That is why these are matrix formulas: broad powders in which constituents are tuned to one another, with the cofactors that make them usable and with a digestive or prebiotic base. You are the host — Home Of Symbiotic Teams — of thousands of billions of micro-organisms, and much of what we offer is only finished off in that interplay. That co-metabolism is not a slogan but the reason an X-Fusion looks the way it does.
Several ranges come in three variants: alpha, beta and gamma. Each variant has its own centre of gravity, so you can work more precisely.
No bulk filler — the serving weight is the sum of the active constituents. Every batch tested according to Triple T (Trace · Test · Trust), screened for prohibited substances, made in Belgium.
Focus: Advanced matrix formulas, synergy, cellular energy, long-term vitality, specific biological goals.
Not everyone needs the same thing at the same moment. One day you are short on fibre, another on protein, and on a long training day above all on carbohydrate. A fixed all-in-one shake forces you to take all three, or none.
The Fraction range cuts the building blocks apart. Fibre, protein and carbohydrate come separately, measured out per sachet, so you need weigh nothing and carry nothing you do not need that day. You stir a sachet into your drink or a dish and so build your own daily composition — alongside your normal food, not instead of it.
Here too the starting point of the whole range applies: you are the host of thousands of billions of micro-organisms, and the way you process a protein or a fibre is always an interplay between you and them. Hence the digestive enzymes and the prebiotic base in the fractions, and hence the advice to build fibre up rather than go all in at once.
No bulk filler, everything on the label, every batch tested according to Triple T (Trace · Test · Trust) and screened for prohibited substances. Made in Belgium.
Focus: Smart macronutrients, staggered protein release, modular building blocks, tailored nutrition.
Thirty-three capsule modules, and each module answers one question. That is deliberate: put everything in one jar at once and you can no longer bring any substance to a meaningful dose.
Biotics therefore works the other way round. Each module is built around one theme — enzymatic digestion, the gut barrier, histamine, the liver, sleep, resistance — and within that gets a dosage that means something. Want two themes at once? Then you stack two modules. That is what we mean by modular, and it is why with every formula we look at the total of what you take together, not just at the single jar.
The thinking behind it is co-metabolism. You are the host — Home Of Symbiotic Teams — of thousands of billions of micro-organisms, and virtually everything we offer passes through that cooperation. That is why practically every module carries cobiotics, plant enzymes or prebiotic fibres as its base.
Several ranges come in alpha, beta and gamma. Each variant has its own centre of gravity, so you can work more precisely. Plant-based HPMC capsules, no bulk filler, everything with its quantity on the label. Every batch tested according to Triple T (Trace · Test · Trust), screened for prohibited substances, made in Belgium.
Focus: Targeted support, enzymatic processes, barrier function, sensitivities to histamine, lactose and gluten.
Some things you do not want to do forever, but you do want to do well for a while. A spell of poor sleep, a winter that pulls at your resistance, a digestion out of its rhythm: that calls for no lifelong supplement but a protocol with a beginning and an end.
That is a ComboRoll. Several modules that belong together, bundled in one box and spread across the parts of the day. That spreading is no packaging trick — certain nutrients compete with each other for the same uptake route, and by pulling them apart over morning, midday and evening each gets its own window. One box instead of three jars, one rhythm instead of three.
Here too we start from co-metabolism: you are the host — Home Of Symbiotic Teams — of thousands of billions of micro-organisms, and a protocol that skips your gut skips half the work. Hence the cobiotics, the enzymes and the prebiotic fibres that run through practically every ComboRoll.
A ComboRoll is stackable with the individual modules, and you can alternate it with another protocol when your routine changes. No bulk filler, everything on the label. Every batch tested according to Triple T (Trace · Test · Trust), screened for prohibited substances, made in Belgium.
Focus: Temporary optimisation, targeted rebalancing of specific processes, protocols with a beginning and an end.
Of all the advice about food there is one that is strikingly simple: do not just eat healthily, above all eat variedly. The number of different plants passing through your diet each week turns out to be one of the most useful measures of the richness of the ecosystem in your gut. Thirty a week is the guide figure that circulates — and most of us reach a good deal fewer.
The HERO range turns that figure into a scoop. One serving brings thirty different plant constituents at once, and each variant takes a different angle. Ferment works with thirty fermented foods, Phyto with thirty polyphenol-rich fruits, leaves and algae, Tolerant with thirty vegetables, seeds and culinary herbs without sharp flavourings, and Fuel builds a complete base with forty-five whole foods and twenty-four vitamins and minerals. HERO 75+ goes one step broader still.
You are the host — Home Of Symbiotic Teams — of thousands of billions of micro-organisms, and variety is literally their food. Do build up though: fibre-rich and fermented food takes getting used to, so start with half a scoop.
No bulk filler, everything on the label. Every batch tested according to Triple T (Trace · Test · Trust) and screened for prohibited substances. Made in Belgium.
Focus: The thirty-plants philosophy, plant diversity, richness of the microbiome.
Anyone who trains hard knows the problem: the formula that scores best on paper is often precisely the one your stomach cannot tolerate during exertion. Under heavy load blood flow shifts away from your digestion, and then absorption becomes the real bottleneck — not the dose on the jar.
Gutletic is built around that bottleneck. The range follows the three moments of a session — before, during and after — and every formula gets a base that supports digestion instead of burdening it: plant enzymes, prebiotic fibres, cobiotics. That is the gut-sport axis, and it is exactly what we mean by co-metabolism: you are the host — Home Of Symbiotic Teams — of thousands of billions of micro-organisms, on the bike and in the gym too.
The alpha, beta and gamma variants exist to allow more targeted work: each has its own centre of gravity.
No bulk filler, everything with its quantity on the label. Every batch is tested according to Triple T (Trace · Test · Trust) and screened for prohibited substances; if you compete, do ask us for the certificate of analysis for your batch. Made in Belgium.
Focus: The gut-sport axis, uptake under physical load, gut stress from exertion.
With muscle building almost everything is about quantity: how many grams of protein, how many scoops, how many times a day. The question missing is how much of it you absorb — and that is the question the Growth range starts with.
That is why every formula carries a digestion layer alongside the protein: bromelain and papain, protease, lactase where it makes sense, and cobiotics that accompany the whole. That is the gut-muscle axis. You are the host — Home Of Symbiotic Teams — of thousands of billions of micro-organisms, and they help decide what is left of your meal. A protein you do not digest builds nothing; it only gives you a heavy stomach.
The ranges run in levels — base, build and max. That is deliberate: you start at the entry level, you let your digestion get used to it, and only then do you increase the serving. That way you build up without the first week making you abandon the whole plan. The levels are also stackable with the Fraction range, if you want to add a specific building block.
No bulk filler, everything with its quantity on the label. Every batch tested according to Triple T (Trace · Test · Trust) and screened for prohibited substances. Made in Belgium.
Focus: The gut-muscle axis, built up through efficient uptake and co-metabolism.
