Aspartame: instructions for use
The sweetener aspartame is a synthetic sugar substitute that is 150 to 200 times sweeter. It is a white powder, odorless and highly soluble in water. It is marked on product labels as E 951. After entering the body, it is very quickly absorbed, metabolized in the liver, involved in transamination reactions, 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 give the 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 significant.
The undeniable 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 breaks down when heated. There is no point in using it for baking and other desserts - they will lose their sweetness. Today, aspartame is allowed in the USA, a number of European countries, and Russia. Maximum daily dose 40 mg/kg per day

My main goal is to be healthier, which means stronger and more beautiful!
We use sports nutrition for the sake of a beautiful and healthy body, we want to fill the diet with missing elements and become better. But the situation may turn out to be the opposite, because By using such supplements, we additionally enrich the body not only with nutritional components, but also with harmful chemical compounds.
This is why a large number of professional athletes and people who simply want to take care of themselves are beginning to switch to mono-products - these are proteins in their pure form, containing only protein and no ballast. Think about it: is it worth once again overloading the body with dubious substances? For what? For the sake of taste and immediate pleasure?
And you can add the desired taste to protein supplements yourself - add juice or milk instead of water, cocoa, vanilla, or spices, fruits - there are a lot of options, don’t be afraid to experiment.

The history of the creation of the sweetener aspartame
The sweetener was discovered by accident in 1965, while working on a pharmacological drug designed to fight stomach ulcers - chemist James Schlatter simply licked his finger. The intermediately synthesized aspartame was the methyl ester of the dipeptide of two amino acids: aspartic and phenylalanine. Below you see a photo of the formula.
Thus began the promotion of a new sweetener to the market, the value of which after 20 years amounted to more than $1 billion per year. Since 1981, aspartame has been legal in the UK and USA. At the same time, a series of investigations and additional research into the safety of this sweetener begins. We will also figure out how and why exactly aspartame is actually harmful.
If you know enough about aspartame, then I recommend that you familiarize yourself with other similar artificial sweeteners:
Why is aspartame harmful?
There have always been discussions in the scientific world regarding the harmlessness of aspartame, which continue to this day. All official sources unanimously declare that it is not toxic, but independent studies say the opposite, citing many references to scientific works of various institutes around the world.
To be fair, consumers are also not happy with the quality and effect of this sweetener. In the United States alone, the Federal Food Administration has received hundreds of thousands of complaints about aspartame. And this is almost 80% of all consumer complaints about food additives. What exactly raises numerous questions?
Contraindications
The only officially recognized contraindication for use is the disease phenylketonuria - aspartame is prohibited for people suffering from it. It is really dangerous for them, even fatal.
Side effects
Meanwhile, many independent studies have confirmed that long-term use of tablets of this sweetener causes headaches, blurred vision, ringing in the ears, insomnia and allergies.
In animals on which the sweetener was tested, cases of brain cancer were observed. So you see that aspartame does more harm than good, as is the case with saccharin and cyclamate.
How long does diluted protein last?
On average, manufacturers indicate that diluted protein can be stored for several hours; this mainly depends on the liquid in which the dilution was made, on the air temperature and on the cooking conditions: the microbiological cleanliness of dishes, hands and the air in the room where the products were measured. Milk, even sterilized, in a cocktail sours very quickly without refrigeration, and it is irrational to store it for more than 2-3 hours. In essence, the “life” period of a diluted cocktail is enough for the duration of training, so that you can drink half of the cocktail before and half after it.
Cocktails diluted in cold water or juice with natural preservatives can be stored for up to 10 hours. Microbiological spoilage in them does not begin as quickly as in dairy products, but they separate more strongly and require additional whipping before use. What’s much worse is that protein is destroyed in them. Even if the drink remains safe for health, it may lose its special properties. And then preliminary breeding becomes a pointless waste of money.
Storing a diluted shake is not the best option; ideally, a protein shake is diluted immediately before use, which is what the manufacturers insist on. Therefore, if you have to prepare a drink in advance, it is advisable to check with the manufacturer how long the diluted protein of a particular brand can be stored and under what conditions.

Sweetener E 951 and weight loss
Like other artificial sweeteners, aspartame does not cause a feeling of satiety, that is, products containing it provoke a person to absorb more and more portions.
- Sweet drinks do not quench thirst, but, on the contrary, spur it on, as a thick, sugary taste remains in the mouth.
- Yogurt with aspartame or diet sweets also do not contribute to weight loss, because serotonin, which is responsible for the feeling of fullness and pleasure from eating sweet foods, does not appear.
Thus, the appetite is only stimulated, and the amount of food, therefore, increases. Which leads to overeating and not losing extra pounds, as intended, but to weight gain.
When the situation is serious
Sperm acquires a bitter taste in many diseases. These are diseases associated with impaired excretion of tissue breakdown products. This happens with the outcomes of all kidney and liver diseases:
- For acute and chronic renal failure.
- For chronic liver failure.
- For chronic processes associated with defects in the immune system, long-term (tuberculosis, cancer, systemic diseases).
Kidney failure is accompanied by the accumulation in the blood of a large amount of urea and potassium salts, which give the semen a sharp, bitter-ammonia taste. Due to concomitant inflammation of the prostate gland, the volume of ejaculate is increased. Adequate treatment of kidney diseases, which lead to insufficient excretion of urea, eliminates the bitterness of the secretions of the sex glands.
Sperm may have a bitter taste due to some diseases.
Chronic liver failure is accompanied by jaundice and impaired synthesis of protein structures. The ejaculate becomes bitter and yellow. Its quantity is decreasing. Treatment of this condition is a difficult task for doctors; often, after long-term treatment, the outcome remains sad.
Tuberculosis is a disease that requires constant long-term use of bitter-tasting medications. The ejaculate becomes bitter due to the medications. Even their abolition for a long time leaves the bitterness of the secretions of the sex glands. In other cases, if a man does not feel healthy, the seminal fluid may be bitter for various reasons (thickening of the blood, temporary increase in the blood of breakdown products, microbial toxins, viruses). A doctor will always help clarify the situation.
Methanol is the result of the breakdown of aspartame
But this is not the worst thing about consuming 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 at least somehow justified, especially since they can also be found in fruits and juices, then the presence of methanol causes heated debate to this day. This monohydric alcohol is considered a poison, and there is no way to justify its existence in food. The reaction of aspartame to decompose into harmful substances occurs even with slight heating. 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 dangerous to human health.
Trends
The latest market trend is the creation of combined protein drugs. For example, casein is added to whey protein. It is absorbed slowly and serves as a source of replenishment of amino acid levels in the blood for a long time. The combination of whey protein and casein is suitable for taking during the day and before bed. It allows you to avoid catabolism caused by a long break between meals and a night break in nutrition.
Recently, soy protein concentrate or isolate has been added to protein. It digests almost as quickly as whey protein and is high in arginine, glutamine and BCAAs. In addition, soy protein speeds up recovery.
Some of the new protein products include egg protein. By definition, it is devoid of carbohydrates and actively affects the secretion of anabolic hormones.
Is aspartame safe 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 by children, pregnant and lactating women. Official sources claim that it is the most studied and safest synthetic sweetener used by humans. However, I would not recommend consumption to expectant mothers, 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 dessert or a sweet drink, because the GI (glycemic index) of this sweetener is zero.
How to get rid of hypolactasia
Before buying lactose-free products, it is best to try to get rid of lactose intolerance. Experts say that such a cure is quite possible. There are several methods for this:
- First, you need to determine whether a person has a negative reaction to fermented milk products. If not, he can consume casein and in some cases whey shakes. In this case, you need to start with small portions.
- You can also try drinking 1/4 cup of milk once a day after a heavy meal to get rid of lactose intolerance. Gradually, once every 2 weeks, you should increase the portion in the absence of negative manifestations.
If these methods do not help, preference should be given to lactose-free mixtures.
Where is the sweetener aspartame found?
In what products is this sugar substitute found? Today, in the retail chain you can find more than 6,000 types of products that contain aspartame.
Here is a list of these products with maximum content levels:
- sweet soda (including Coca Cola light and zero),
- fruit yoghurts,
- chewing gum,
- sweets for diabetics,
- sports nutrition,
- a number of medications,
- vitamins for children and adults.
And also in such sugar substitutes as: and. The maximum permissible level of aspartame E 951, approved by the FDA (American Food and Drug Administration) consumed per day is 50 mg/kg of weight. Products, including household sweetener, contain several times less. Accordingly, the acceptable 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.
Which protein is best for weight loss?
To answer this question, you first need to understand why protein is beneficial for weight loss.
In short:
- firstly, more calories are spent on digesting protein than on digesting fats and carbohydrates;
This means that if you ate a 100-calorie serving of protein food, about 30 of them will go towards actual digestion. For carbohydrates and fats, this figure is half as much.
Naturally, for those who want to lose weight, this has some advantage, since for the same calorie intake of food, food high in protein “contains fewer calories that can be stored as fat.”
- secondly, protein saturates better, i.e. I want to eat less.
This, in turn, means that if you regularly include protein foods in your diet, your appetite is suppressed faster, you want to eat less, and the number of calories entering the body with it decreases.
From this point of view, not all proteins are equally good and effective. The best proteins for weight loss are those that have a whole molecule that needs to be “broken down,” “digested.”
These include all natural protein products, as well as most sports proteins (casein, egg protein, whey protein, soy protein), but not in the form of hydrolysates .
The hydrolyzate is designed to accelerate absorption, which is achieved by first splitting the protein molecule into so-called peptides or chains of amino acids.
Naturally, when losing weight, it is better to choose products with a low fat content.
But this type of sports proteins, such as gainers, are contraindicated for weight loss due to the high carbohydrate content in them: the combination of protein + carbohydrates is good for gaining muscle mass, but there are too many carbohydrates.
Increasing the proportion of protein in the diet is a principle of many effective diets. How and with the help of what products - sports proteins or natural ones - to do this, the decision is yours.
There is no magic in sports proteins that specifically enhances fat burning.
Many effective diets recommend increasing the proportion of protein in your diet. It is better to do this with the help of whole natural protein products. Sports proteins do not have any fat-burning magic.
Methods for determining aspartame in food products
In 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, issuing a certificate of conformity to it.
Spectrophotometric method
In this way, the presence of aspartame in carbonated soft drinks is determined after they are produced. The analysis uses a spectrophotometer, colorimeter and balance.
Chromatographic method
Needed to clarify the sweetener concentration value. Liquid chromatograph is used as the main analysis equipment.
Not all proteins are created equal
Some companies are accustomed to reducing the cost of sports nutrition by using dry margarine - cheap vegetable cream - as an energy source. However, health is not something you should skimp on. Long-term consumption of vegetable cream increases blood cholesterol levels and inhibits the function of the immune system.
Among other things, the low cost of protein concentrates may be due to outdated protein extraction technologies that involve the use of toxic substances with an insufficient degree of rectification.
Products from LACTOMIN.RU are manufactured according to the highest EU technological standards, which guarantees the highest degree of purification and the absence of vegetable cream and palm oil in the list of ingredients.
What else you need to know about aspartame
Combinations of sweeteners
This sugar substitute can be used in combination with others, for example, you can often find a combination of aspartame acesulfame potassium (salt).
Manufacturers often put them together, since the “duet” has a high sweetness coefficient of 300 units, while separately for both substances it does not exceed 200.
Release form
A sweetener with aspartame can be:
- in the form of tablets, for example, Milford (300 tablets),
- 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 available for sale not only on the Internet on specialized websites, 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 to get a more complete picture and consulting with a qualified nutritionist.

VPX, a leader in sports nutrition, was the first to bring you 100% isolated whey. Patented cross-sectional four-level filtration technology allows us to selectively select and target microparticles such as IGF-1, IGF-2, which have specific functional properties such as stimulating muscle growth. One of the many benefits of our VPX 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.
Featuring four-stage cross-sectional filtration technology with di-, tri- and quad-peptide isolates, VPX has earned the title of sports nutrition leader in creatine biochemistry. Demand VPX Zero Carb SRO 100% Cross-Quarter Filtered Whey Protein Isolate, fortified with whey peptide isolates.
How to choose the right product?
To lose weight, choose a protein without added sugar or dextrins/maltodextrins (starch sweeteners). Additionally, choose ones with added branched chain amino acids (BCAAs), as they promote muscle growth, but not fat.
The best choice for weight loss is whey isolate.
Whey isolate is virtually fat-free for those looking to eliminate as much fat as possible from their diet. This is usually lactose for those few people who are very sensitive to the low levels of lactose found in whey concentrate.
Package
Packaging significantly affects the price of the product and how convenient it will be to take the protein on the road or during transportation. The usual, so to speak, packaging (can and bag), most often, has a large volume and weight, and is the best option, never take protein in bulk, do not risk your health.
Compound
The main thing we look for on the packaging is the protein content in the mixture. The best choice is the one with the highest protein content per serving. Since we have determined that whey isolate is best for weight loss, it should contain 24-25 grams of protein per serving.
Also pay attention to the origin of the protein. Often, along with normal protein, vegetable protein with a low BC and poor amino acid composition is also used. This is done in order to make protein cheaper; such a product is worth going a mile for the sake of your health.
What is used instead of sugar?
There are two categories of sweeteners - safe and hazardous to health. Safe ones are also divided into two types - natural: such as Steviazid, Neogrispedin, Gritserizin (licorice), Thaumatin, Sorbitol. And synthetic ones - Sucralose.
Dangerous and toxic sweeteners - Aspartame, Saccharin, Cyclamate, Acesulfame potassium.
So, if you see any of these dangerous substances in the composition, it is better to put it back on the shelf.
Questions and answers about Zero Carb SRO:
Why add protein to your nutrition program?
Protein causes 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's 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 it also has a staggeringly higher biological value (BV). BV is a numerical measure of exactly how much protein your body can retain (nitrogen retention) and use in processes such as hormone production, muscle building, fat breakdown (via pancreatic hyperglycemic hormone), use and convert into energy, etc. d. The greater the biological value of the protein, the greater the ability to carry out these processes. Whey protein isolate has 34% greater biological value than whey protein concentrate. Leaders in the whey protein industry claim that their product is 68%, and now even 77%, better than chicken egg white. This is blatantly untrue. A protein that claims to be 68%, and now even 77%, “better than egg white” is WPC and in fact, it is only 15% better than chicken egg and 34% less effective than Zero Carb SRO of VPX.
What are the benefits of adding di-, tri-, and quad-peptide 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. Currently, VPX Zero Carb SRO is the only whey protein isolate containing whey peptide isolates. Whey peptide hydrolysates are found in other proteins that are extracted from low-grade whey protein concentrate. Whey peptide isolates have replaced hydrolysates. Glutamine peptides are 16 times more bioavailable than L-glutamine. Once again, we find that because peptides are not free amino acids (amino acids starting with L), they are the preferred way to consume protein. Although simple laboratory experiments cannot test for the presence of glutamine peptides in WPI, we now know that VPX's Zero Carb SRO is naturally rich in glutamine peptides, even before being enhanced with additional glutamine peptides. Scientists agree that glutamine plays an important role in muscle size and growth.
What is Microfraction Selection Technology?
Microparticle Screening Technology (MST) is the result of using four different processing methods to produce whey protein isolate to increase the number of specific microparticles (tiny 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 (naturally found in WPI) that, among many other benefits, is very effective at stimulating muscle building and fat burning. MST is VPX's scientific breakthrough in developing Zero Carb Protein to increase the amount of specific microparticles such as IGF-1, IGF-2, Glucomacropeptides, Bovine Whey Albumin, etc. Zero Carb Whey Protein Isolate, developed with and used in MST is one step ahead in the science of protein technology. There are still many mysteries that we have not solved in the separation of more effective components - microparticles using MST. Zero Carb SRO and VPX will continue to evolve, with MST bringing more new information to 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).

How to take protein without lactose
Taking lactose-free protein is no different from regular sports nutrition. Athletes who do not experience stomach problems can take the supplement before meals, diluting it with water or juice.
For athletes suffering from gastrointestinal diseases, it is better to take protein with meals or after meals; it is also recommended to choose cocktails that do not contain fruit acid, dyes and flavoring additives.
Note that lactose-free protein is available in different flavors; most often, athletes prefer banana or chocolate flavored supplements.
On average, one serving of the supplement, depending on the manufacturer, contains from 25 to 35 grams; you can take no more than three servings of the cocktail per day.
pros
Lactose-free protein has enormous benefits:
- It does not contain lactose, which allows people suffering from hypolactasia to take the supplement.
- Strengthens the immune system.
- Helps strengthen bones.
- Enriches the body with all useful micro and macroelements.
- Gives good weight gain.
- Improves digestion.
- Helps burn excess subcutaneous fat.
Glucose-free protein is gentle on the body and does not cause unpleasant symptoms in lactose intolerant people.

Reviews
Reviews about lactose-free protein are mostly positive, as they allow athletes with hypolactasia to lead a normal lifestyle and achieve good athletic results.
Andrey, 32 years old. I am lactose intolerant and tried whey protein which gave me stomach pain. I started taking lactose-free protein and did not notice any unpleasant symptoms. I gain weight gradually, prepare a cocktail in the morning and evening in small quantities. I like that you can choose any flavor of protein. My favorite ones are the orange, banana, and chocolate flavors.
Olga, 28 years old. I take lactose-free protein and am happy with the results. I tried it with chocolate and strawberry flavors. The excess fat is gone, my figure is toned, and I don’t miss workouts. I drink a cocktail in the morning and evening; I don’t have the opportunity during the day because I’m at work. The herbal supplement does not put a strain on the body, it is quickly absorbed and quite effective. Since I don’t need a lot of weight gain, I choose protein with amino acids to burn excess fat and speed up metabolism. Also, the mixture can be added to baked goods, which gives it a unique taste.
Alexander, 28 years old.
Since childhood, I have suffered from intolerance to dairy products, so lactose-free protein is the only way for me to gradually gain weight without the use of steroids. In a couple of months of taking it, I gained five kilograms. The muscles are elastic and of high quality, the volume is maintained. I mostly choose coffee-flavored cocktails, but there is a huge range of protein on the market with different flavors to suit any preference.
