ISO90 WHEY PROTEIN

ROAR ISO90 Whey Protein Isolate

ROAR ISO90 Whey Protein Isolate is formulated to provide a high protein concentration – at least 10 per cent higher than that achieved by conventional concentration methods – as well as a complete amino acid profile and a quick and convenient preparation. A high-quality protein source designed for sportspeople, athletes and anyone wishing to precisely supplement their daily protein intake.
Protein contributes to the growth and maintenance of muscle mass. Thanks to their high protein content, ROAR ISO90 whey protein isolates provide a significant dose of protein using only a small amount of powder.

What is WPI?

WPI stands for Whey Protein Isolate. The term WPI 90 refers to a raw material obtained through filtration and concentration processes, with a protein content of up to approximately 90% on a dry matter basis.
Compared to standard protein concentrates, protein isolates have a higher protein density and lower levels of non-protein components. The result is a powder suitable for those seeking a minimalist formulation and a concentrated source of protein.

Complete proteins and essential amino acids

Whey protein isolates contain all nine essential amino acids, including the branched-chain amino acids (BCAAs) and leucine.
Essential amino acids cannot be synthesised by the body in sufficient quantities and must be obtained through the diet. The natural presence of leucine and the other essential amino acids makes whey a complete protein source and particularly valuable in sports nutrition.

Muscle protein synthesis and whey protein

Protein intake provides the body with the amino acids necessary for the synthesis of new muscle proteins. This process, known as muscle protein synthesis, is particularly important after physical exercise and during recovery periods.
In a study published in the *Journal of Applied Physiology*, Tang and colleagues compared the response in muscle protein synthesis following the intake of hydrolysed whey protein, micellar casein and soya protein isolate. In young men undergoing resistance training, whey protein produced a more rapid increase in blood concentrations of essential amino acids, BCAAs and leucine. Under the experimental conditions of the study, the post-exercise muscle protein synthesis response was greater with whey protein than with the other sources examined.
The study focused on hydrolysed whey proteins and not on this finished product, but it helps to explain the scientific interest in the rapid availability of amino acids typical of whey proteins.

Digestion, absorption and bioavailability

The quality of a protein does not depend solely on the percentage stated on the label. The amino acid composition, digestion and the amount of amino acids that become available in the bloodstream after consumption are also important.
Whey proteins are commonly referred to as fast-digesting proteins. A comprehensive review of 18 randomised clinical trials, involving over 600 participants, confirmed that the type and dose of protein influence the rate of digestion, the absorption of amino acids and their subsequent availability in the blood.
This makes whey protein isolates a practical solution when you wish to provide the body with complete proteins and readily available amino acids, particularly after training or at times of the day when your diet does not meet your protein requirements.

High solubility and quick preparation

Solubility refers to the ability of protein powder to hydrate and disperse in liquid. It should not be confused with bioavailability, which instead relates to the digestion and nutritional utilisation of amino acids.
ROAR ISO90 protein isolates have been selected to ensure rapid dispersion and a uniform consistency. The powder mixes easily with water using a standard shaker, allowing you to prepare a smooth, pleasant-tasting protein drink in just a few seconds.
Research into the functional properties of WPI highlights that solubility and dispersion can be influenced by the raw material, the production process, heat treatment, pH and preparation conditions. To achieve the best result, it is therefore advisable to pour in the liquid first and then add the powder.

Why choose ROAR ISO90 protein isolate?

• High protein concentration
• Complete amino acid profile
• Naturally rich in essential amino acids, BCAAs and leucine
• Rapid absorption of amino acids
• Excellent solubility in water
• Quick and easy to prepare
• Suitable for consumption after training or throughout the day
• Suitable for programmes focused on strength, muscle hypertrophy and muscle maintenance

When should you take protein isolate?

Protein isolate can be taken after a workout, at breakfast or as a protein supplement throughout the day. There is no single ‘best’ time that suits everyone: the total amount of protein consumed daily and how it is spread across different meals are more important than a very narrow time window.
After exercise, however, a serving of whey isolate is a practical way to provide the body with complete protein and essential amino acids.

How to prepare ROAR ISO90 whey isolate

Add one serving of the product to the amount of water indicated on the label and shake vigorously for a few seconds. The amount of water can be adjusted according to the desired consistency and flavour intensity.
To ensure even mixing:

• pour the water into the shaker first;
• add the powder;
• shake for a few seconds;
• consume immediately after preparation.

Frequently asked questions about WPI 90 and ROAR ISO90 protein isolates

What does WPI 90 mean?

WPI stands for Whey Protein Isolate. The number 90 indicates a raw material characterised by a protein concentration of close to 90 per cent on a dry matter basis. The percentage in the finished product may vary depending on the other ingredients in the formulation and should be checked in the nutritional table.

Do protein isolates help with muscle growth?

Protein contributes to the growth and maintenance of muscle mass. However, the result depends on your overall protein intake, diet, training programme and recovery.

Do whey isolates contain all the essential amino acids?

Yes. Whey protein has a complete amino acid profile and provides all nine essential amino acids, including leucine, isoleucine and valine.

Are protein isolates bioavailable?

Whey proteins are considered high-quality protein sources. They are digested and absorbed rapidly, resulting in the prompt availability of amino acids in the bloodstream. However, it is more accurate to refer to digestion, absorption and amino acid availability rather than attributing an absolute value to ‘bioavailability’ that has not been measured for the individual product.

Are protein isolates soluble in water?

WPI has good solubility properties, but the result depends on the quality of the raw material, the production process and the method of preparation. Using a shaker and adding the powder after the water makes it easier to achieve a smooth drink.

Is it better to take protein isolates before or after a workout?

They can be taken at either time. Post-workout, they offer a practical way to consume complete proteins, but it is primarily meeting your daily protein requirements that determines the effectiveness of your nutritional strategy.

Is ROAR ISO90 a protein that meets high standards and holds certifications?

Yes, ROAR ISO90 is tested for heavy metals and microbiologically; it undergoes sieving and visual inspection at various stages.

What data can confirm that the declared protein percentages are accurate?

You should be wary of prices that are significantly lower than the market average. WPI90 is a high-quality, high-cost raw material. Another important factor is the amino acid profile table; high levels of glycine, arginine or glutamine may indicate counterfeit products containing low-cost amino acids (a form of ‘protein spiking’ or dilution).

Why might ROAR ISO90 in limited-edition flavours have different protein and calorie profiles?

Limited editions of ROAR ISO90 often contain additions such as nuts and dried fruit. The nutritional values for this part of the product are correctly calculated as a proportion of the total.

I can no longer find a limited edition flavour – when will it be available again?

Limited edition flavours are produced seasonally and, often in response to high customer demand, require longer production times and are only made at certain times of the year depending on the availability of raw materials.
