The True Strength of Whey

Whey Protein Isolates (WPIs) are the purest form of whey protein that currently exists. WPIs are costly to use, but rate among the best proteins that money can buy. That’s why they’re the first ingredient you read on the Gold Standard 100% Whey label. By using WPI as the primary ingredient along with premium ultra-filtered whey protein concentrate (WPC), we’re able to pack 24 grams of muscle-building protein into every serving. ON’s attention to detail also extends to mixability. This superior quality powder has been instantized to mix easily using a shaker cup or just a glass and spoon. There’s no doubt that this is the standard by which all other whey proteins are measured.

Beyond The Basics

  • Nearly 79% Protein by Weight (24 g of protein per 30.4 g serving size)
  • Whey Protein Isolates (WPI) main ingredient.
  • Whey Protein Microfractions from whey protein isolate and ultra-filtered whey protein concentrate.
  • Over 4 grams of glutamine & glutamic acid in each serving
  • More than 5 grams of the branched chain amino acids (BCAAs) leucine, isoleucine, and valine in each serving
  • The “Gold Standard” for protein quality.

Suggested Use

Consume enough protein to meet your daily protein requirements through a combination of high protein foods and protein supplements. For the best results, consume your daily protein allotment over several small meals spread evenly throughout the day.

Spoon Stirred: Gold Standard 100% Whey is instantized. That means if you forgot your shaker cup or don’t have time to get out the blender, just add one rounded scoop of Gold Standard 100% Whey to a glass filled with 6-8 oz of water or your favorite beverage. Then mix it up with a spoon. Stir for 30 seconds or until powder is completely dissolved. Tip: Adjust the taste for your Gold Standard 100% Whey by varying the amount of liquid that you use to prepare it. For a bolder flavor with slightly more body and sweetness, mix each scoop with 4-6 oz of water, milk, or your favorite beverage. For a milder tasting, less sweet shake, use 8-10 oz of liquid per scoop.

Shaker Cup: Bringing a shaker cup with you to the gym is the best way to get a dose of protein immediately after you workout. Just pour in 6-8 oz of your preferred beverage and then add one rounded scoop of Gold Standard 100% Whey to your shaker cup. Cover and shake for 25-30 seconds.

Blender: Add one rounded scoop of Gold Standard 100% Whey to a blender filled with 6-8 oz of water or your favorite beverage. Blend for 20-30 seconds. Then add 1 or 2 ice cubes and blend for an additional 30 seconds. Shake Up Your Shake: By adding fresh or frozen fruits, peanut butter, flaxseed oil, coconut and other ingredients, you can make an even more delicious shake. Stack Your Shake: You can make Gold Standard 100% Whey an even better post workout product by adding supplements like creatine, glutamine, BCAA, and concentrated carbohydrate powders.

Think Outside The Glass: Gold Standard 100% Whey can be used for more than just protein shakes. Try mixing a scoop into oatmeal, yogurt, or the milk that you pour over your morning breakfast cereal. Better yet, increase the protein content of muffins, cookies, brownies, etc. by adding a scoop or two to your baked goods recipes.

Whey protein (whey protein) is easily absorbed by the body and has excellent metabolic qualities, filling the body with protein with high biological value. It also contains the largest amount of BCAA branched chain essential amino acids. During periods of increased stress and training, protein synthesis in the body decreases sharply and protein mobilizes into free amino acids. Skeletal muscle pulls the essential BCAAs from the bloodstream and breaks it down into glucose for energy. Due to the ability of BCAAs to provide the body with a continuous source of energy during exercise, their role in the body is so unique and high.

Whey Protein During Trainingas a protein shake will be the best support for the body. The use of whey protein as an additional component of the diet of sports nutrition is growing steadily with increasing technological capabilities of the industry, due to which whey is becoming a more affordable product for the consumer. Whey protein isolate contains a high concentration of essential BCAA amino acids (26 grams of amino acids per 100 grams of protein) and is, in fact, one of the most environmentally friendly types of protein with high bioavailability of calcium. Whey protein concentrate is available in various protein concentrations (34% to 80%). The isolate, in turn, contains more than 80% protein, reaching a limit of 90% -95%. The protein contained in whey protein contains sub-fractions such as beta-lactoglobulin, immunoglobulins.


In order to maintain health and overall well-being, it is recommended to take 0.8 grams of protein per 1 kilogram of weight. However, a person’s protein requirements also depend on his lifestyle, physical condition, general health, age, gender, carbohydrate status, level of protein needs, level of physical fitness, type of exercise, their intensity and duration, as well as tasks assigned to one or another protein. The recommended 0.8 grams per kilogram of weight is enough for people with a sedentary lifestyle, but with increased physical exertion, the need for protein increases significantly.

Nutritionists believe that 1.5 grams of protein per 1 kilogram of weight is considered enough protein to get maximum results from athletes. This protein intake is recommended to maintain the nitrogen balance in the body, or to increase the nitrogen balance, thereby increasing muscle growth.

We must not forget that the nutritional needs of athletes involved in bodybuilding, weightlifting and wrestling are significantly different from the needs in other sports. Studies studying the nitrogen balance in the human body have revealed the protein ratio necessary to maintain a positive balance that improves endurance and strength of athletes. This ratio is 2 grams of protein per 1 kilogram of human weight. Bodybuilders, as you know, most of the protein consumed is taken from whey protein.

Despite this, some people consume more than 2 grams of protein per kilogram of weight. They justify this by the fact that an increase in muscle mass requires an increase in the intensity of training and, accordingly, additional protein intake.

But for the proper nutrition of muscles with amino acids, it is not necessary to take an increased amount of protein in order to increase your muscle mass. After all, there is no protein that the body could use at 100%. Loss of efficiency in the assimilation of high-quality protein is not more than 30%, and with low-quality protein – 60%. In addition, taking a very large amount of protein increases the metabolic load on the internal organs of a person and the body as a whole. Instead of overloading the body with excess protein, it is better to use a protein with high biological value, such as whey protein.


Any protein can be called a good product, but some of them have significant advantages compared to others, namely:

  • excellent balance of essential and non-essential amino acids;
  • high concentration of BCAA ;
  • low in fat and cholesterol.

Protein quality is also determined by a special assessment of PDCAAS (Protein Digestibility Corrected Amino Acid Score), which is determined by the amino acid composition of the protein and the body’s ability to absorb them.

According to this estimate, the PDCAAS of an ideal protein, in which all the essential amino acids necessary for the human body are present, is 1.00. Whey protein PDCAAS is 1.14, which is significantly higher than soy protein PDCAAS of 1.00.

At the moment, whey protein is the most saturated with essential amino acids, which make up more than 60% of the total composition of whey.


Whey protein contains a high level of essential BCAA amino acids (approximately 26%). An important difference between these amino acids is the fact that during periods of increased stress, when the body needs them most, BCAAs entering our body are metabolized directly in the muscles, and not in the liver, like most amino acids. As the need for BCAAs increases with increasing workload during training, athletes who want to maintain and increase muscle mass find a solution in the form of increased consumption of these essential amino acids.

100 grams of whey protein contains approximately 10 grams of leucine, 6.5 grams of isoleucine and 5.5 grams of valine. Some changes in the amino acid composition of whey protein are associated with a difference in the origin and method of processing the protein. That is, different whey protein production methods give different levels of BCAA essential amino acids.

BCAA: recovery assistance

  • BCAAs, according to most scientists, reduce muscle breakdown during training, allowing athletes to conduct more intense and longer trainings. It is proved that the additional intake of BCAAs helps to restore the body of athletes after intense training. Modern scientific theory shows that during prolonged training BCAAs, getting into the skeletal muscles of the body, are divided into a carbon and nitrogen component. The carbon component acts as fuel, and the nitrogen component is spent on the production of alanine, an amino acid that ultimately forms glucose, thereby producing energy. For athletes who want to preserve their muscle mass, whey protein, due to the high content of essential amino acids in it, BCAA is an excellent solution to this problem. As a result of overtraining, stress and injuries muscle tissue is constantly exposed to processes of catabolism (destruction of muscle tissue). That is why BCAAs, thanks to their restorative abilities, are an extremely useful supplement in the nutrition of any athlete.

BCAA: Fatigue Assistant

  • Most professional runners and cyclists know for themselves what it means to give all the best. During the competition, both runners and cyclists, one hour after the start, begin to feel tired. It has been suggested that ingestion of the essential BCAA amino acids with food will help the body delay the moment of fatigue during prolonged aerobic exercise, delaying central nervous system fatigue. The main hypothesis is that increasing the concentration of 5-HT serotonin receptor in the brain may interfere with the proper functioning of the central nervous system during exercise. An increase in the concentration of 5-HT may occur due to an increased level of the essential amino acid tryptophan, a precursor of serotonin. Transportation of free tryptophan through the blood barrier is carried out in conjunction with BCAA, in other words, the more BCAA, the less free tryptophan can enter the blood plasma. Thus, an increase in the concentration of 5-HT is proportional to an increase in the content of free tryptophan in blood plasma and is inversely proportional to BCAA.

    It is suggested that lowering the level of free tryptophan helps to reduce fatigue of the central nervous system. Several studies have shown that the use of BCAAs improves performance among runners, footballers, cyclists and skiers.


The role of lactoferrin in sports

Lactoferrin is a multifunctional protein from the transferrin family in a significant amount contained in whey protein. Transferrins are plasma proteins that transport iron ions, as well as produce energy and regulate hemoglobin and red blood cells. The iron content in the body is a very important factor for any athlete. Most athletes rely on aerobic exercise in their workouts, which requires a significant amount of oxygen. Oxygen transportation and diffusion is limited during aerobic exercise. Iron is one of the key elements in cellular metabolism and oxygen transportation. In fact, this element is a hemoglobin based acceptor. Iron deficiency can lead to impaired red blood cell performance in the bone marrow of the body, as well as a decrease in athlete’s aerobic performance. Some athletes, to increase oxygenation, take iron by injection into the blood, which is very at risk of getting hemosiderosis – a disease caused by a violation of the exchange of iron-containing pigments. In addition, people who take iron orally also run the risk of having an upset stomach. Lactoferrin is suitable as an iron-containing food without adverse reactions to increase oxygenation. Lactoferrin in the body also acts as an antioxidant, binding iron and preventing it from acting in conjunction with free radicals. Today there is a lot of scientific evidence that free radicals are the cause of muscle destruction in athletes. Lactoferrin plays an important physiological role in the fight against free radicals. In addition, lactoferrin is also involved in the protection of the cellular system by regulating macrophage activity and stimulating lymphocyte proliferation. The immune-modulating potential of lactoferrin is very useful for an athlete, especially in conditions of critical stress during intense training.

Whey protein is rich in arginine and lysine. Arginine and lysine are some of the main amino acids that stimulate growth hormone. Protein is able to stimulate the release of growth hormone, which is an anabolic hormone or, in other words, a stimulator of muscle growth. Since the use of steroid drugs was prohibited, the modern sports nutrition industry is based solely on natural substances that contribute to the construction of muscle tissue. Whey protein is the best alternative to anabolic androgenic steroids.

Whey Protein Contains Glutamine, which is a conditionally essential amino acid. In addition, there is evidence of scientific studies showing that glutamine contributes to the body’s fight against fatigue and overtraining syndrome in athletes. This is very important, since in certain cases, this amino acid will be very necessary in the diet. It acts as a fuel for cell division. Glutamine in skeletal muscle is 60% of the total amino acid content. That is why athletes are constantly watching to prevent any lack of glutamine, as this will lead to a reduction in muscle growth and the development of catabolism. Glutamine also plays an important role in the binding of ammonia molecules, which are produced as a by-product of muscles during periods of increased stress, therefore, consuming whey protein,

Under stress caused by increased stresses, the body’s need for glutamine increases significantly. Glutamine is also used in sports drinks and bars. Developers of sports supplements can extend the effect of the product by adding the amino acid glutamine to the formula.

The role of glucomacropeptides in sports

Glucomacropeptides are formed during the processing of cheese as a result of the reaction of chymosin with K-casein. This protein is a kappa-casein peptide that is formed by serum ultrafiltration. Whey protein consists of 15-20% of glucomacropeptides. Glucomacropeptides are biologically active proteins that positively affect the digestive system, which is a very important factor for any athlete. Numerous scientific studies have shown that glucomacropeptides stimulate the synthesis and release of cholecystokinin, a neuropeptide hormone that plays a key role in regulating digestive functions and suppressing appetite. In addition, antiviral activity, growth of bifidobacteria in the intestine, improvement of calcium absorption, belong to the beneficial functions of glucomacropeptides.


Today, the sports nutrition market is rich in protein products, the main source of protein in which is whey protein. Protein categories that include whey protein as part of the product’s compound profile include only high-protein foods (20 to 50 grams of protein per serving): nutritional supplements , mass- gaining foods , gainers and pre-workout drinks. Each category is designed for specific goals and results, such as providing energy during the training period, increasing calories for weight gain, and also restoring muscle tissue after training.

In the US and Europe, whey protein is also used as the basis for home-made sports nutrition, such as high-protein pastries and protein shakes.
