Pure Protein Unflavored

5 (100%) 2 votes

Pure, tasteless protein is a natural product that does not contain harmful additives. It is undesirable for our body to get various sweeteners, flavor enhancers, dyes and other ballast substances. The best protein option is natural. It comes in powder form and has a neutral taste.

If you need an additional source of vegetarian protein, pure protein is the best choice. It is also suitable for people on a variety of diets. Pure protein powder contains no artificial additives that are harmful to health. Why not buy flavored protein powders? Let's consider this in the article.

What is the point of such a choice?

Natural protein without additives is the element sports nutrition designed for building muscle mass and supplying the muscles needed. It is also used for. Many popular blends are proteins and additives used to enhance the not always palatable end product.

The only source of high quality protein is pure protein without additives. Sports nutrition uses a combination of several protein supplements in powder form.

Many athletes prefer quality protein that is free from various additives.

Conventionally, all types of organic protein are divided into two groups:

  • animal origin (, egg, casein);
  • vegetable, or vegetarian (soy, rice and others).

Vegetarian protein is labeled "raw" on the package. Unsweetened protein has a neutral taste and is well absorbed by the body.

The enhanced cleaning system eliminates unnecessary additives in the composition:

  • fats;
  • artificial sweeteners (aspartame, sodium acesulfame, sucralose);
  • flavor enhancers (eg monosodium glutamate);
  • hormones;
  • antibiotics;
  • heavy metals.

For weight loss, it is recommended to use a vegetarian protein that does not have impurities of animal origin. Its only drawback is the peculiar taste of the mixture, which you need to get used to. If protein flavor is important, it is important to choose a product that contains only natural additives. Stevia provides a sweet taste, while vanilla is used for a pleasant aroma.

Unflavored Protein Types

Pure protein powder is a source of amino acids necessary for our body. The classification includes the following types:

Sports nutrition is necessary, but you only need to choose it correctly

  • whey (easily digestible milk protein with several purification methods);
  • ("Slow" protein obtained by curdling milk is used for long-term muscle saturation with amino acids);
  • soy (has a high concentration of lysine and glutamine, suitable for people with lactose intolerance);
  • dairy (medium digestibility, includes high level lactose);
  • egg (with a high biological value, it does not contain lactose, since it is an extract of egg white);
  • collagen (used for intensive construction, further restoration connective tissues);
  • a combination mixture (a versatile product that includes several types of protein).

Highly digestible whey protein, in turn, has the following subspecies:

  • concentrate (cheap protein obtained with minimal purification);
  • (more complex purification, providing a high level of pure protein with a minimum of lactose);
  • hydrolyzate (maximum purification quality, ensuring good digestibility).

High purity whey protein has a complex production process. It breaks down quickly compared to whole proteins. At maximum purification, protein without additives has high price compared to other products.

How to choose a product?

Many sports nutrition brands produce protein powder in the form of isolates or concentrates.

It is important to understand that protein is a raw material, which in its essence should be natural.

When choosing a safe product, it is important to pay attention to:

  1. The composition of the product. This is the percentage of protein in a serving, the type of processing, and necessarily the amino acid composition. The mixtures are additionally enriched with vitamins, minerals, creatinine, glutamine. A useful product does not contain "ballast" substances that create additional load on the body.
  2. Manufacturer's firm. Unaddressed protein powder is available from most sports nutrition brands. In each case, the product is selected individually. It is not only the purpose of the application that matters, but also the value for money.
  3. Supplements. An important point- gainers are not used as natural protein. These are special mixtures used to build muscle as quickly as possible.

When choosing a vegetarian protein, you should go for reputable brands. Purchase organic certified products. This means meeting the established quality standards for this category of sports nutrition.

Be wary of the bio label. This marking does not require pre-certification, which does not guarantee the quality of the final product.

Rating of products without taste

According to reviews, the best proteins tasteless is the products of such companies:

Today there are many manufacturers who produce powder without various impurities - dyes, lactose, fats, and so on.

Sunwarrior

Sunwarrior offers raw fermented protein based on sprouted brown rice. It is made from whole grains using low temperatures, but without the use of hydrolysis or other harmful processes.

Hemp Foods Hemp Protein

Hemp Protein Based Vegetarian Protein. Source of omega acids, alpha amino acids, lysine. This composition provides maximum nutritional value. A significant disadvantage of the product is its rather specific taste.

Finally

Natural protein without additives or colorants - this is the powder form of the product. Is a source of plant or animal protein High Quality... Raw, or vegetarian, protein often tastes specific. This product is free of fats, colors, artificial sweeteners, or other additives that would impair training performance.

When choosing a protein powder, it is important to consider the following criteria: product composition, protein content, manufacturing company. A popular combination of several types of protein supplements that are used at different times of the day.

Greetings to all! I continue the topic of the variety of refined sugar substitutes. The time has come for aspartame (e951): what harm does the sweetener do, what products contain and what methods of determining whether it is possible for a pregnant body and children.
Today, the chemical industry offers us many opportunities to avoid sugar consumption without denying ourselves our favorite sweets. One of the most popular sweeteners among manufacturers is aspartame, used both on its own and in combination with other ingredients. Since its synthesis, this sweetener has come under frequent attacks - let's try to figure out how harmful it is and how it affects the body.

Aspartame: instructions for use

The sweetener aspartame is a synthetic sugar substitute 150 to 200 times sweeter than it. It is a white powder, odorless and readily soluble in water. It is marked on E 951 product labels.
After entering the body, it is very quickly absorbed, metabolized in the liver, including in the transamination reaction, and then excreted by the kidneys.

Calorie content

The calorie content of aspartame is quite high - as much as 400 kcal per 100g, however, to impart a sweet taste of this sweetener, such a small amount is required that when calculating the energy value, these figures are not taken into account as essential.

The indisputable advantage of aspartame is its rich sweet taste, devoid of impurities and additional shades, which allows it to be used on its own, unlike other artificial sweeteners.
However, it is thermally unstable and degrades when heated. It is pointless to use it for baking and other desserts - they will lose their sweetness.
Today, aspartame is approved in the USA, a number of European countries, and Russia. The maximum daily dose is 40 mg / kg per day

The history of the sweetener aspartame

The sweetener was discovered by accident, in 1965, in the course of work on a pharmacological drug designed to fight stomach ulcers - chemist James Schlatter simply licked his finger.
The intermediate synthesized aspartame was a methyl ester of a dipeptide of two amino acids: aspartic and phenylalanine. Below is a photo of the formula.

This is how the promotion of a new sugar substitute on the market began, the volume of which, after 20 years, amounted to more than $ 1 billion per year. Since 1981, aspartame has been licensed in the United Kingdom and the United States.
At the same time, a number of investigations and additional studies of the safety of this sweetener began. We will also figure out how much and what exactly is actually harmful aspartame.

If you know enough about aspartame, I recommend that you familiarize yourself with other similar artificial sweeteners:

Why is aspartame harmful?

There have always been discussions about the harmlessness of aspartame in the scientific world, which continue to this day. All official sources unanimously declare its non-toxicity, but independent studies say the opposite, citing many links to scientific work the most diverse institutions of the world.

To be fair, consumers are also not happy with the quality and action of this sweetener. In the United States alone, the FDA has received hundreds of thousands of complaints about aspartame. And this is almost 80% of all consumer claims to food additives.
What exactly raises many questions?

Contraindications

The only officially recognized contraindication to use is phenylketonuria disease - for people suffering from it, aspartame is prohibited. It is really dangerous for them, up to and including death.

Side effects

Meanwhile, many independent studies have confirmed that long-term use of tablets of this sweetener causes headache, blurred vision, ringing in the ears, insomnia and allergies.

Cases of brain cancer have been observed in animals tested on the sweetener. So you can see that there is more harm than good from aspartame, as is the case with saccharin and cyclamate.

Sweetener E 951 and weight loss

Like other artificial sweeteners, aspartame does not cause a feeling of fullness, that is, products containing it provoke a person to absorb more and more portions.

  • Sugary drinks do not quench your thirst, but, on the contrary, whip it up, as a thick sugary taste remains in your mouth.
  • Yoghurts with aspartame or diet sweets also do not contribute to weight loss, because serotonin, which is responsible for the feeling of satiety and pleasure from eating sugary foods, does not appear.

Thus, the appetite is only spurred on, and the amount of food, therefore, increases. Which leads to overeating and not throwing off extra pounds, as intended, but to weight gain.

Methanol is the result of the breakdown of aspartame

But this is not the worst thing when using aspartame. The fact is that in our body the sweetener breaks down into amino acids (aspartic and phenylalanine) and methanol.

And if the existence of the first two components is somehow justified, especially since they can also be found in fruits and juices, then the presence of methanol causes heated discussions to this day. This monohydric alcohol is considered a poison, and there is no way to justify its existence in food.
The decomposition of aspartame into harmful substances occurs even with slight heating. So it is enough for the thermometer to rise to 30 ° C for the sweetener to turn into formaldehyde, methanol and phenylalanine. All of these are toxic substances that are extremely hazardous to human health.

Is aspartame possible for pregnant and lactating women

Despite the unpleasant facts described above, today aspartame is approved for use in more than 100 countries around the world for children, and for pregnant and lactating women.
Officials say it is the most studied and safest synthetic sweetener ever used by humans. However, I would not recommend the use to either expectant mothers, or nursing women, or children.

It is believed that the main benefit of aspartame is that people suffering from diabetes without fear for their lives due to a sharp jump in insulin can afford a dessert or a sweet drink, because the GI (glycemic index) of this sweetener is zero.

Where is the sweetener aspartame contained

What foods is this sugar substitute found in? Today, in the trading network, you can find more than 6000 names of products that contain aspartame in their composition.

Here is a list of these top-level foods:

  • sweet soda (including coca cola light and zero),
  • fruit yoghurts,
  • chewing gum,
  • sweets for diabetics,
  • sports nutrition,
  • a number of drugs,
  • vitamins for children and adults.

And also in such sugar substitutes as: and.
Maximum acceptable level Aspartame E 951, approved by the FDA (American Food and Drug Administration) consumed per day is 50 mg / kg of body weight.
Products, including directly household sweetener, contain several times less of it. Accordingly, the allowable daily intake of aspartame can be calculated based on the maximum value determined by the FDA and WHO of 50 mg / kg body weight or 40 mg / kg.

Methods for the determination of aspartame in food

In the industry, there are a number of arbitration methods of analysis to determine the concentration of a particular substance in a product (for control in case of disagreement), and, on the basis of this, issue a certificate of conformity to it.

Spectrophotometric method

This determines the presence of aspartame in carbonated soft drinks after they have been made.
The analysis uses a spectrophotometer, colorimeter, and balance.

Chromatographic method

It is needed to clarify the value of the concentration of the sweetener.
A liquid chromatograph is used as the main analysis equipment.

What else you need to know about aspartame

Combinations of sugar substitutes

This sugar substitute can be used in combination with others, for example, the combination of aspartame acesulfame potassium (salt) is often found.

Manufacturers often put them together, since the "duet" has a large sweetness coefficient equal to 300 units, while separately for both substances it does not exceed 200.

Release form

An aspartame sweetener can be:

  • in the form of tablets, for example, milford (300 tab),
  • in liquid - Milford Suss, as it is highly soluble.

Aspartame in sports nutrition (protein)

If you still have doubts about this sweetener, you can purchase products that do not contain it.
Chewing gum without aspartame or protein for athletes is on sale not only on the Internet at specialized sites, but also in supermarkets. Aspartame in sports nutrition does not affect muscle growth, since it is not absorbed by the body and is added solely to improve the taste of tasteless protein.
Whether or not to use aspartame as a sweetener is up to you. In any case, it is worth reading scientific articles on this topic for a more complete picture and consulting a qualified nutritionist.

With warmth and care, endocrinologist Dilyara Lebedeva

Aspartame is the healthiest and most commonly used sugar substitute. Montignac himself recommends its use for people who are overweight or obese.
Common opinion about useful properties aspartame is not true, and Montignac may be wrong too. In fact, aspartame is very harmful. Yes, it has a low calorie content and good digestibility, but the taste is almost 200 times sweeter than sugar. For the first time, aspartame began to be produced by the US company G.D.Searle in the second half of the 60s. XX century. However, the company's loss amounted to $ 28 million due to numerous lawsuits of people who, after consuming aspartame, instead of losing weight, plumped up, and about 800 women developed amniotic inflammation during pregnancy. The company had to reimburse the victims for treatment costs and compensate for moral damages.
Despite this, aspartame is very popular in the United States and in many other countries. In Russia, it is sold under the brands Nutrisvit, Aspamiks, Miwon (from South Korea), Enzimologa (from Mexico), Ajinomoto (from Japan) and others. Unfortunately, it is used in the production of about 5-6 thousand types of drinks, food products, children's vitamins and medicines. In restaurants, aspartame is used in the preparation of dietary meals. They are used in the production of low-calorie light drinks and chewing gums. Aspartame is widely used by manufacturers due to its low cost compared to granulated sugar. There is evidence from independent studies showing that long-term use of aspartame in food can cause ringing in the ears, insomnia, depression, allergies, headaches, and brain cancer. People who frequently drink drinks containing aspartame are at a higher risk of developing systemic lupus erythematosus or multiple sclerosis. Included in it phenylalanine and aspartic acid with a lack of other amino acids that are converted into protein, passing into the brain, they cause damage to the nerve cells of the brain, up to the loss of memory. For pregnant women, the use of aspartame is highly undesirable, even in small quantities, as this can lead to birth defects in the child's brain.
One of the components of aspartame, phenylalanine, accumulates in the brain, leading to mental retardation, depression, unmotivated outbursts of aggression, hormonal disorders, and deterioration in mood and well-being. Consuming aspartame can also lead to allergic reactions. Increases appetite in some people. In addition, aspartame contains methanol, which causes visual impairment in those who drink cheap, low-quality drinks. Once in the body, methanol is converted into the carcinogen diketopiperazine, formaldehyde and their toxic compounds. Formaldehyde is a poisonous substance, comparable in degree of danger to arsenic and hydrocyanic acid.
Roughly 90 percent of the sugary drinks on the market contain aspartame. Kvass containing this sweetener cannot be considered kvass. Such a drink leaves a sugary aftertaste in the mouth, and real kvass prepared with sourdough should leave a feeling of freshness.
Drinks containing aspartame should not be heated or left in the hot sun, as heated drink converts aspartame into poisonous methanol. That is why the bottles say "Drink chilled!" Sometimes it's ok to drink small bottle drink containing aspartame, but if you drink large quantities of such drinks every day, it will cause colossal harm to health.
On food labels, aspartame is hidden under the code E951.
In the manufacture of foods and sugary drinks, it is sometimes mixed with another sweetener, acesulfame-K. It instantly delivers a sweet taste and aspartame delivers a long-lasting aftertaste. This mixing does not make the sweetener less harmful.

Please stop talking nonsense, the harm of aspartame is not medically proven! there is not a single official study proving this IMMEDIATE harm, only studies affiliated with competitors in the production of sweeteners conducted in violation of honey. requirements.

How often do you read the composition on the regular foods that you eat? For example, almost all chewing gum contains aspartame ... people chew them in packs ... alive and well. With 1 can, nothing bad will happen

In chewing gum, it seems to me the dose is still not as large as in this btsaa, but thanks for the info))

there are people who do not chew gum or drink soda and do not use sugar substitutes at all. Asparam reduces intelligence and causes a bunch of allergic reactions, plus phenylalanine reduces the production of serotonin in the brain - is it necessary for a normal athlete ?? For a bodybuilder, yes - mental decline is a proven fact in rats. I bought this can of BCAA when I was actively involved in physical training before the volleyball season, in general, for a whole year I periodically tried light sports supplements from creatine to glutamine, of course, everything was first studied, but as a rule, all experimenters are pitching, which still eat a lot of everything, so definitely nothing it is not possible to say until you try. Does this BCAA work - it works, no doubt, I am in complex with this BCAA, NAG and - the taste, this is not chewing gum and not soda, there is such a concentration of asparam - mother do not burn if two liters from one spoon are sweeter than in soda, and they propose to dilute it by 300 ml. The problem with all of these supplements is that they have fucking synthetics like asaparma in them. I regularly take tests - a habit from sports, plus I have asthma, so it is important to be careful with medications, I advise everyone who eats chemistry - take a blood test, at least a general blood test. Personally, when using this particular BCAA and NAG (from the same company) for three months, it was installed high growth immunoglobulin E (these are antibodies, the growth of which indicates an allergic reaction) to take then to find out the reasons for other indicators - it was pointless, I knew what I was eating, everything was written in a notebook, removing from this BCAA - the allergy indicators were restored. This is my personal example and experience, it is not necessary that everyone will have the same, but I, as an athlete, I have everything in my sport as a CCM - I advise you to do tests - these are blood tests, urine tests, and all such banal ones as blood pressure, pulse in the morning, at rest, an electrocardiogram and once a year an ultrasound of the heart, and of course anyone who eats chemistry - liver, kidney and spleen - should do all the tests regularly.

By using chemistry, a person consciously takes a certain risk to health. Accordingly, the test results will not be comforting because the organism is reconstructed to the regime imposed on it. You will see changes in indicators in 2 weeks. And what do you want to see in your analyzes? Will you look scared and leave everything at once? And also, be sure to consult with a doctor from the clinic, who does not fumble about anything in sports medicine. Good luck in sports.

VPX, a leader in sports nutrition, was the first to bring you 100% isolated whey. The patented technology of cross-sectional four-level filtration allows us to selectively select and act on microparticles such as IGF-1, IGF-2, which have such specific functional qualities as stimulating muscle growth. One of the many benefits of our VPX technology Zero Carb SRO is the ability to introduce isolated quadrapeptides. It is these peptides that stimulate the release of opiate-like chemicals into the body, increasing the pain threshold during exercise.

VPX has earned the title of creatine biochemistry leader in sports nutrition with di-, tri- and quadropeptide isolates technology. Demand 100% Isolate whey protein VPX Zero Carb SRO cross four-level filtration, fortified with serum peptide isolates.

Frequently asked questions about Zero Carb SRO:

Why Add Protein to Your Nutrition Program?
Protein triggers the release of many muscle-building (GF, IGF-1) and fat burning hormones (pancreatic hyperglycemic hormone, GF, etc.). It also helps build and repair muscle tissue. Frequent consumption of high quality protein helps maintain muscle mass.

What is VPX Zero Carb SRO?
VPX Zero Carb SRO is 100% Whey Protein Isolate. Let me explain. Proteins such as Designer, VyoPro and Pro Max all contain whey protein concentrate or WPC. Whey Protein Isolate, or WPI, is not only much purer than WPC, but also has a staggering biological value (BV). BV is a numerical measure of how much protein your body can hold (nitrogen retention) and use in processes such as hormone production, muscle building, breakdown of body fat (via pancreatic hyperglycemic hormone), use and convert into energy, etc. e. The more biological value a protein has, the greater the ability to carry out these processes. Whey Protein Isolate has 34% more BV than Whey Protein Concentrate. Whey Protein Leaders Claim 68%, And Now Even "77% Better Than Protein chicken eggs". This is a blatant lie. Protein that claims to be 68%, and now even 77% "better than chicken egg protein" is WPC and in fact, it is only 15% better than chicken egg and 34% less effective than Zero Carb SRO by VPX.

What are the benefits of adding di-, tri- and quadropeptide isolates and glutamine peptides to Zero Carb SRO?
Research has shown that short chains of amino acids called peptides are more readily absorbed by the body than free amino acids or high molecular weight whey proteins. The body prefers to consume protein in the form of peptides. VPX Zero Carb SRO is currently the only whey protein isolate containing whey peptide isolates. Whey Peptide Hydrolysates are found in other proteins that are derived from low-grade whey protein concentrate. Whey peptide isolates have replaced hydrolysates. Glutamine peptides are 16 times more bioavailable than L-glutamine. And again we come to the conclusion that due to the fact that peptides are not free amino acids(amino acids starting with the letter L), they are the preferred way to consume protein. Although the simplest laboratory experiments cannot test for the presence of glutamine peptides in WPI, we now know that VPX's Zero Carb SRO is naturally loaded with glutamine peptides, even before it was enhanced with additional glutamine peptides. Scientists agree that glutamine plays important role in muscle size and height.

What is Microfraction Selection Technology?
Microparticle Selection Technology (MST) is the result of using four different technological methods for the production of whey protein isolate in order to increase the number of special microparticles (the smallest particles that make up the protein) that have beneficial functional properties. For example, IGF-1 or Insulin-like Growth Factor 1 is a microparticle of whey protein isolate. IGF-1 is a powerful hormone (found naturally in WPI) that, among many other benefits, is very effective in stimulating muscle growth and fat burning. MST is VPX's scientific breakthrough in the development of Zero Carb Protein to increase the amount of specific microparticles such as IGF-1, IGF-2, Glucomacropeptides, Bovine Serum Albumin, etc. used in MST is one step ahead in the science of protein technology. We have not yet solved many of the mysteries in separating the more effective microparticulates using MST. Zero Carb SRO and VPX will continue to evolve, with MST more and more new information emerging in science.

VPX Zero Carb SRO became the first commercially available whey protein isolate in 1995. In 1998, after VPX created Microfraction Selection Technology, other companies were just starting to learn about WPI (Whey Protein Isolate).
