IO Genix Iso Clear

What is IO Genix Iso Clear?

IO Genix Iso Clear, also sold as IsoZero Clear, is a whey protein isolate formulated to give a clear, fruity drink rather than a creamy shake. That is the principle behind clear whey: the protein stays dissolved in an acidic medium, and the result drinks like a lemonade.

The raw material is Lacprodan® Clearshake, a whey isolate from the Danish supplier Arla, which accounts for 96.82 % of the formula in the Strawberry flavour. The rest fits into five lines: flavouring, citric acid as an acidity regulator, sucralose and acesulfame K as sweeteners, azorubine as a colour, and pyridoxine hydrochloride for the vitamin B6.

The flavours available: Blueberry, Iced Peach, Piña Colada, Strawberry Mojito, Watermelon and Raspberry. The register is that of a summer drink, not a milky dessert. The product also sits in our whey isolate and IO Genix ranges.

What does a 30 g serving contain?

* Column calculated from the values declared for 30 g, as the manufacturer does not publish a per-100 g column. The figures correspond to the Strawberry flavour and may vary slightly from one flavour to another. One inconsistency worth flagging: the manufacturer declares 0.5 mg of vitamin B6 per serving and states 118 % of the NRV. Yet the European nutrient reference value for vitamin B6 is 1.4 mg: 0.5 mg represents roughly 36 % of it. We reproduce the amount exactly as declared and flag the discrepancy rather than settling it on the brand's behalf. Dietary fibre is not declared.

The figure that matters is 26 g of protein for 105 kcal. Referred back to the powder, that gives 86.6 % protein, which is the top of the range for a clear whey — many stop at around 80 %. Put another way, a 30 g serving delivers as much protein as a 33 g serving of standard whey, without the fat or the lactose.

A word on a claim doing the rounds that needs correcting: this product is not "zero sugar, zero fat". It contains 0.06 g of sugars and 0.03 g of fat per serving. These are negligible amounts over the course of a day, and the product comfortably meets the regulatory thresholds allowing the "high protein" and "low fat" statements — but zero means zero, and that is not the case here. The claims authorised for protein are precise: it contributes to a growth in muscle mass, to the maintenance of muscle mass and to the maintenance of normal bones. Vitamin B6 contributes to normal energy-yielding metabolism. There is no recovery claim for protein, contrary to what you read everywhere.

How do you prepare Iso Clear?

Serving: 30 g. Liquid: 250 ml of cold water. When: after training, or as a snack between meals. How often: 1 to 2 servings a day depending on your protein requirements. How long: no limit — it is a protein, and it can be used for as long as your diet needs it.

Method matters more here than with other products. Pour the water in first, then the powder, shake, then let the foam settle for about thirty seconds before drinking: whey proteins are surface-active and stabilise the bubbles. The more you shake, the longer the foam holds.

Two things you must never do with a clear whey. Never mix it with milk: the acidity destabilises the casein, and the mixture curdles and turns grainy. And never cook with it: a clear whey coagulates with heat and has no business in a pancake. For cooking, keep a whey concentrate. Served very cold, with crushed ice, it is noticeably better.

Who is Iso Clear for, and who is it not for?

The strongest use case is this one: you can no longer face milky shakes. Digestive heaviness, the taste of vanilla every single day, or simply a summer session after which nothing creamy will go down. A protein you do not drink is of no use to anyone, and that is exactly where this format earns its place. During a cutting phase, 105 kcal a serving is also hard to beat.

It is not suitable in several cases. The product contains MILK and may contain traces of NUTS, EGGS, FISH and SOYA. In the event of a diagnosed cow's milk protein allergy it is contraindicated: filtration removes the lactose, not the proteins. It is not recommended for children or pregnant women. The colour azorubine also carries the following mandatory statement: may have an adverse effect on activity and attention in children.

What you should not expect from it: anything more than any other protein. A clear isolate is neither better nor less well absorbed than a standard isolate, and the 26 g of protein do exactly the same job. The difference is one of comfort, not of performance. And it is not a slimming product: it helps you hold a deficit, and it is the deficit that does the work.

Iso Clear or a standard whey isolate?

Both start from the same raw material. What separates them is the formulation and the use you will make of it.

A standard whey isolate wins in three situations. You take two or three servings a day: the price per kilo of protein becomes decisive, and the standard isolate is almost always better placed. You cook with your powder: a clear whey coagulates, a standard whey does not. You want a creamy drink that keeps you going between two meals: a clear whey, by design, does not satisfy in the same way. On those three points, Iso Clear loses.

Iso Clear wins when the drink itself is the problem. Difficulty digesting milky shakes, weariness of the milky taste, the urge for a cold, tangy drink at the end of a session. It also wins on protein density: 86.6 % puts this product above the average for its category. The calculation that settles it is the same on both sides: price of the tub, divided by its weight in kilos, divided by the protein content per 100 g. Do it before you buy. All the families can be compared in the protein range.

Frequently asked questions

How many servings are there in a tub?

The net weight of the tub does not appear in the data supplied by the manufacturer, so we cannot calculate the exact number of servings. What we do know for certain: the reference serving weighs 30 g and provides 26 g of protein. Divide the weight shown on the packaging by 30 to get the count.

Can it be mixed with milk?

No. The acidity of the formula makes the casein in milk flocculate: the mixture curdles and turns grainy. Use cold water, 250 ml per 30 g serving. That is a constraint of every product in this category, not a fault of this one.

Does it contain lactose?

Very little. The filtration process removes most of the lactose and the fat, which explains the 0.36 g of carbohydrate per serving. Many people who struggle with a whey concentrate tolerate it without difficulty. Take care not to confuse this with milk protein allergy, which rules the product out.

Why does the stated vitamin B6 percentage not add up?

The manufacturer declares 0.5 mg per serving and states 118 % of the NRV, which is inconsistent with the European reference value of 1.4 mg. We flag the discrepancy rather than correcting it ourselves. In any case, vitamin B6 is not the reason to buy this product.

How do you avoid the foam?

Pour the water in before the powder, shake moderately, then let it stand for thirty seconds. Taking the metal whisk out of the shaker helps a great deal. Made in advance and left in the fridge for an hour, the drink is more pleasant and completely clear.

Can it be used in baking?

No. A clear whey coagulates when cooked and gives a rubbery texture. For pancakes, cookies or protein cakes, you need a whey concentrate or a casein from the casein range.

Does the composition change from one flavour to another?

Yes, slightly. The published values correspond to the Strawberry flavour, where the isolate accounts for 96.82 % of the formula and the protein concentration reaches 86.6 %. The manufacturer indicates a content of around 86 % depending on the flavour. The colour used also varies from one flavour to the next.

Where can you buy IO Genix Iso Clear?

The flavours can be ordered from this page, and we ship anywhere in France and Europe. With a tangy drink, flavour remains the one criterion no product page can replace: it is the kind of product you choose better by talking to someone who has drunk it.

Our shop in Vendargues, about ten minutes from Montpellier, keeps the full range in stock. If you are looking instead for an amino acid drink to sip during training, take a look at the EAA range.
