Isolate production
Whey protein isolate is isolated from whey using mainly two methods:
- Ion exchange when exposed to high temperatures.
- Gentle microfiltration method.
The isolation of protein from whey must take place without damaging the structure of the raw material. Animal fats, cholesterol, and lactose are removed from the composition, preserving nutrients, which is very difficult.
The price of whey protein isolate produced by the second method is slightly higher. It has additional properties:
- Increase immunity.
- Retain oxygen in tissues.
- It is well absorbed without creating digestive problems.
The cheaper option also has all the qualities of isolates, but you should not expect additional beneficial properties from them.
There are other ways to obtain an insulator, but they are complex and unprofitable, so they are no longer used. Whey turned out to be an ideal source of protein.
Egg protein also exists, but its production involves some difficulties. It is made by only 8 companies, and therefore the prices are quite high. To obtain egg protein isolate, whole eggs are used, which guarantees a close-to-ideal amino acid composition and the presence of pure egg albumin.
Whey protein dosage
• The minimum intake of whey protein isolate should be 2g/kg. weight per day;
• It is not advisable to take more than 30g at a time. protein, otherwise a larger intake of the specified amount will not be absorbed by the body and will simply be excreted through urine.
• Break your intake into 5-6 parts to get the required amount of protein per day.
• Example: your weight is 80 kg, which means 80 kg * 2 (dose in grams per kg of weight) = 160 g. protein per day., you consume approximately 20-30% of protein from regular food, which means 160 g - 20% = 128 g. Protein is the minimum you need to consume per day. Let's go further 128 gr. / 30 (maximum protein intake at one time) = 4.2, rounded up to 5, this is the number of times you need to drink whey protein isolate per day.
How to take whey protein
• In the morning immediately after sleep, before eating;
• Between main meals;
• 30-45 minutes before training;
• Immediately after the training session, but no more than 1 hour after its completion;
Composition and properties of the isolate?
Protein isolate composition:
- Whey proteins – from 90%.
- Amino acids.
- Complex of macroelements (magnesium, potassium, calcium and others).
The exact formula and ratio of components depend on the brand. Each manufacturer uses a special method for obtaining the product. Proteins contain lactoferrin, beta-lactoglobulin, immunoglobulins, alpha-lactalbumin. Only undenatured isolate fully retains all its properties.
Action
Protein isolate helps burn fat without harming muscle mass. As a result, the muscles become more prominent and gain volume. Amino acids provide the body with all the necessary substances, neutralizing the harm from reducing carbohydrates and fats in the diet. Macroelements nourish the body and protect against imbalances.
During normal weight loss, exactly the same processes occur, but on a smaller scale, so whey protein isolate works a little differently.
Action:
- It is quickly absorbed and enters directly into the blood and muscles (in just 3 hours).
- Creates a high concentration of free amino acids.
- Stimulates the production of insulin (anabolic hormone).
- Suppresses catabolism.
- Restores muscles after training.
- Reduces appetite.
- Increases fat burning.
- Improves the production of the antioxidant glutathione.
Sports nutrition is aimed at neutralizing negative processes in the body, activating the process of drying and gaining muscle mass. Protein supplements facilitate and accelerate the formation of new muscle fibers and saturate the body with useful substances.

Formulated with Glutamine Peptides, Glutapure Glutamine and N-Acetyl L-Glutamine to rapidly restore and support immune function. The price for 910 grams is approximately 1,770 rubles.
- RPS Nutrition Whey Isolate 100%. The brand has developed a high-quality form of whey protein isolate that contains virtually no carbohydrates and fats. The high protein content per serving makes the product essential for muscle growth and maintenance. The percentage of BJU differs slightly in different flavoring additives. The cost of the supplement for 2,270 grams is approximately 3,290 rubles.
- SAN Platinum Isolate Supreme. The brand has developed a high-quality protein matrix, increasing the protein content by ion exchange to 93%. The composition also contains a small amount of a form of protein hydrolyzate to increase the rate of absorption, BCAAs (7 g per 1 serving) and peptides. This composition makes the supplement an excellent assistant for muscle gain and recovery. A package weighing 912 grams costs approximately 2,500 rubles.
- Dymatize ISO-100. As the manufacturer specifies, the supplement is 100% protein isolate. The supplement is completely lactose-free, making this isolate the best for cutting athletes. A serving of isolate has a high protein content, although the supplement is not completely devoid of carbohydrates (1-2 g per serving). Also contains 5.5 grams of BCAA per serving. The approximate cost for 1362 grams is about 3450 rubles.
- SynTrax Nectar. The supplement does not contain sugar, gluten and fat, and contains large quantities of ultra-filtered undenatured whey isolate, which is not subject to destruction under the influence of high temperatures. A package of 963 grams costs about 2,350 rubles.
Benefits of Whey Isolate
- Fast absorption.
- Balanced cost (before hydrolysates).
- High protein concentration (before concentrates).
- Fewer harmful substances in the composition.
- There are no side effects if you follow the manufacturer's recommendations.
- Supply of all necessary amino acids and macroelements, including essential ones.
- Protein is almost completely absorbed by the body.
- Easy obtaining process (affordable price).
Whey protein isolate is easy to prepare - just dissolve the powder in a liquid - water, tea, juice.
Whey Protein Isolate - What is it?
Whey protein is a sports supplement for gaining muscle mass, which is a concentrated mixture of milk proteins and is obtained by processing cow's milk. In turn, whey protein isolate is dried whey that is maximally purified from fats and lactose. The isolate contains both fast digestion proteins and casein.
The advantage of whey protein is that it contains a full spectrum of amino acids (including BCAAs) in the most optimal form for absorption by the body. Unlike regular food, the body only needs a few minutes to process the protein contained in the isolate and send it to the muscles. This is why whey protein should be taken immediately after finishing a strength training session.
Although you can gain muscle mass without taking sports nutrition - you just need to follow a diet for muscle growth - whey protein isolate makes it easier to control the amount of protein in your diet. This is especially important for those athletes who do not have the opportunity to prepare nutritious meals during the day. Whey isolate can also be useful for weight loss.
Protein isolate composition
Whey protein contains both the amino acids found in cow's milk (including the essential leucine, isoleucine and valine), as well as B vitamins, calcium and other elements beneficial for muscle growth. Isolate is one of the most preferred forms of intake, since it contains virtually no fat (including cholesterol), and is also free of lactose and other sugars contained in milk.
It should be noted that taking whey isolate can cause food allergies in some people - both due to an individual reaction to the denatured protein, and due to the secondary elements contained in sports protein to improve the texture and taste of the product. In its pure form, isolate has a bland milky taste, so manufacturers add flavorings and sweeteners to the composition.
