IO Genix Isoluxe CFM - Grass Fed Whey Isolate

What is IO Genix Isoluxe CFM?

IO Genix Isoluxe CFM is a whey isolate sold in 500 g and 1.5 kg tubs, with a 30 g serving size. Its base is not a single isolate but a pairing of two raw materials the manufacturer names explicitly: Isolac®, a microfiltered whey isolate, and Optipep®, a hydrolysed isolate. The manufacturer states that Isolac® comes from grass-fed cows' milk; we report that claim exactly as it publishes it, without verifying it ourselves.

Three ingredients round out the formula, and each deserves a sentence. A DigeZyme® enzyme complex combining amylase, protease, lactase, lipase and cellulase. A strain of Bacillus coagulans, marketed under the name LactoSpore®. And a natural sweetener, steviol glycosides from stevia — a rare choice in this category, where sucralose dominates.

The flavours listed in 500 g, including an unflavoured Natural version: Chocolate Hazelnut, Strawberry, Bourbon Vanilla, Greek Yoghurt and Blueberry, Dark Chocolate-Coconut, Banana-Pineapple, Peanut Butter, Intense Chocolate and Natural. The 1.5 kg format carries the same list. The rest of the range sits in the IO Genix section.

What does a 30 g serving contain?

* Column calculated from the per-100 g values, as the manufacturer publishes no per-serving column.

Let us be blunt: this table is not precise enough for a product positioned this way. The manufacturer publishes thresholds and a range — "more than 85 g", "less than 5 g", "370 to 380 kcal" — where the labelling on a premium isolate ought to give exact figures. It publishes no "of which saturates" line, no "of which sugars" line and no kilojoule equivalent. And it advertises a full amino acid profile without publishing a single figure from it, which is especially unfortunate on an isolate: that is precisely the data that would justify the price gap with a concentrate. We will not fill any of those boxes with an estimate.

That said, what the threshold guarantees remains solid. More than 85 g of protein per 100 g is squarely isolate territory: a concentrate tops out at around 75 to 80 g. Translated into a serving, that works out at more than 25.5 g of protein for roughly 112 kcal, with less than a gram and a half of carbohydrate and three tenths of a gram of fat. Protein here supplies more than 90% of the product's energy, which qualifies it for the "high protein" nutrition claim, and the applicable regulatory wording is this one: protein contributes to the growth and maintenance of muscle mass.

On the two "bonus" ingredients, let us be clear. No digestive claim is authorised in Europe for an enzyme complex such as DigeZyme®, and no health claim is authorised for a culture such as Bacillus coagulans — the very term "probiotic" is regulated. So we describe their presence, not an effect. Factually: the lactase in the complex is the enzyme that breaks down lactose, which makes sense in a dairy protein. What difference that makes for you, only trying it will tell.

How do you prepare Isoluxe CFM?

Dose: 30 g, i.e. one scoop. Liquid: 200 to 250 ml, ideally very cold water. Timing: after training, on waking, between meals, or at bedtime in a reduced serving. Frequency: 1 to 3 servings a day depending on your needs. Duration: ongoing, no course is required.

Shake vigorously for 20 to 30 seconds in a shaker. The tip that makes the biggest difference to the result: use very cold water, or add two ice cubes. An isolate dissolves better cold, and the fine texture that is its whole appeal disappears in a lukewarm liquid.

The powder also blends very well into pancakes, porridge or a smoothie bowl. The Natural flavour, with no flavouring or sweetener, is the one best suited to that: it imposes nothing on your recipes and leaves you in control of the sweetening. If you are cooking with heat, add the powder at the end — poured into a boiling liquid, protein coagulates.

On format: the 500 g tub covers roughly 16 servings, the 1.5 kg one covers 50. The small format is the right choice for trying a flavour; the large one becomes worthwhile once you have made up your mind, and it brings the cost per serving down. As for when to take it, do not overthink it: what counts is your protein total across the twenty-four hours, not the quarter of an hour after your last set.

Who is this isolate for, and who is it not for?

It targets three specific situations. A strict cutting phase, where every gram of carbohydrate and fat counts. Difficulty digesting dairy proteins, an isolate containing markedly less lactose than a concentrate. And a demand for texture: an isolate gives a thin, fluid drink, where a concentrate stays thicker.

The product contains MILK proteins, and traces of SOYA are possible — the emulsifier is sunflower or soya lecithin depending on the batch. The manufacturer declares it gluten free, advises against it for anyone allergic to milk proteins, and asks pregnant or breastfeeding women to consult a healthcare professional.

It is not for you if your budget is tight: at comparable protein quality, a whey concentrate costs appreciably less per serving, and we set out that trade-off just below. Nor is it for you if you are allergic — rather than merely intolerant — to milk proteins: filtration removes the lactose, not the proteins. Finally, if you want to know precisely what your leucine or BCAA intake is, the absence of a published amino acid profile is a real obstacle.

What not to expect from it: this is neither a weight-loss product, nor a meal replacement, nor a performance product. It is a very clean protein source, and the word "luxury" in the trade name denotes a positioning, not a nutritional property.

Isoluxe CFM or a whey concentrate?

This is the central trade-off in the protein category, and it comes down to three grams.

Here, more than 25.5 g of protein per 30 g serving, less than 1.5 g of carbohydrate, less than 0.3 g of fat. On a decent whey concentrate, reckon on 22 to 23 g of protein, 4 to 5 g of carbohydrate and roughly 1 g of fat for the same serving. The real gap is therefore two to three grams of protein per shake — the equivalent of half an egg white — for an appreciably higher price per serving.

Whey concentrate is the better choice for most people: if your aim is to hit your daily protein total and you digest lactose without trouble, it does the same job for less. We say so plainly, even though it is not the product on this page.

Isoluxe is the better choice in three cases where the gap genuinely pays off. In a strict cutting phase, where 3 g of carbohydrate saved per shake, multiplied by three servings a day, eventually adds up. In cases of digestive discomfort with a concentrate, where the reduced lactose content makes a tangible difference. And if texture matters to you — an isolate is drunk, a concentrate is almost chewed. If you want to go further still on absorption speed, look at the hydrolysed wheys, of which the Optipep® present here is precisely an example.

Frequently asked questions

What is the difference between Isolac® and Optipep®?

They are two distinct raw materials. Isolac® is a whey isolate obtained by microfiltration; Optipep® is a hydrolysed isolate, whose protein chains have been pre-cut. The manufacturer does not publish the proportion of each in the formula, which makes any numerical conclusion impossible. We report their presence, not a ranking.

How many servings in each format?

Roughly 16 servings of 30 g in the 500 g tub, and 50 in the 1.5 kg one. The small format is the right choice for trying a flavour without committing; the large one brings the cost per serving down once you know which one suits you. Note that the 1.5 kg is not available in every flavour.

Why are the nutritional values given as thresholds?

Because the manufacturer publishes "more than 85 g of protein", "less than 5 g of carbohydrate" rather than exact figures. It is a common practice but a poor one on a product of this standing, and we would rather flag it than gloss over it. The values printed on the tub you receive are the ones that apply.

Is the sweetener stevia?

Yes, these are steviol glycosides from stevia, not sucralose or acesulfame K. It is a rare choice in this category. Be aware that stevia leaves a liquorice note on the finish, very noticeable on mild flavours such as vanilla and much less so on chocolate ones.

Is this isolate suitable for people who are lactose intolerant?

An isolate contains markedly less lactose than a concentrate, which is enough for most mild intolerances. The manufacturer does not, however, publish a figure for lactose content, and the lactase in the DigeZyme® complex allows no promises: no digestive claim is authorised for this type of ingredient. If you are allergic to milk proteins, the product should be ruled out.

What is the Natural flavour like?

It contains neither flavouring nor sweetener: it is raw isolate, with a faintly milky, neutral taste. It appeals to two profiles — those who cannot tolerate stevia, and those who cook with their protein and want to control the sweetening themselves. It is only available in the 500 g format.

What is the Bacillus coagulans in the formula for?

It is a spore-forming bacterial strain, added under the name LactoSpore®. As no health claim is authorised in Europe for this type of culture, we will not attribute one to it. If cultures interest you in their own right, our probiotic section offers dedicated products, dosed and presented for that purpose.

Where to buy IO Genix Isoluxe CFM?

Both formats and the full flavour line-up can be ordered from this page, and we ship throughout France and Europe.

A 1.5 kg tub of isolate is a real outlay, and it is exactly the kind of purchase where two minutes of conversation heads off a disappointment. At our Vendargues shop, about ten minutes from Montpellier, the question we ask is not "isolate or concentrate?" but "what brought you to isolate in the first place?". Depending on whether the answer is about digestion, about a cutting phase or about plain habit, the product we recommend is not the same. The full category can be compared in our proteins and in our sports nutrition sections.
