The inventor of GlycoTrol®, Dr. Charles Jarowski, PhD, was the founding Director of Research and Development at Pfizer, Inc., and served in that distinguished position for over twenty years. From Pfizer, Dr. Jarowski accepted the position of professor of Pharmaceutical Sciences at St. John’s University and taught PhD students until his retirement.
Dr. Jarowski spent decades researching blood glucose and cholesterol and the mechanisms controlling them. Dr. Jarowski began his groundbreaking research by taking 60 high protein foods Americans commonly eat and identifying the essential amino acids most frequently lacking – tryptophan, methionine, valine, and lysine. By simply supplementing these four amino acids before a meal, he found that a higher percentage of protein tends to be utilized by the body, reducing waste products and helping to subdue the sugar roller coaster so common after meals.
This radio interview with Dr. Charles Jarowski originally was broadcast in Miami, Florida, and was sponsored by Tunies Natural Grocery and Vitamin Supercenter. The interviewer is Janet Simorelli, and the program is "Healthline."
Dr. Charles Jarowski: Good morning Janet. I’m so happy to be able to hear your voice and answer you.
Janet: Ok, well we’re looking forward to lots of good information for our listeners. Tell our listeners a little bit about your very distinguished career, your first career, because now you’re into a second career.
Dr. Charles Jarowski: Yes, I must say; fate is a really strange thing that happens to an individual. I went to a college of pharmacy to get a pharmacy degree, and while I was there, my dad, when he reached the age of 69, actually had one of his legs removed due to Type II Diabetes, and my sister Anna, when she reached the age of 69, had the same fate befall her.
So, I began to worry, even as a student in a pharmacy school, that maybe I would suffer the same fate. So, after I got my degree, one of the professors encouraged me to go for a doctorate degree, and I got a doctorate degree in pharmaceutical chemistry, and then here’s where fate entered in. There was an opening for a post-doctoral fellowship at the University of Illinois. When I accepted that fellowship and received my doctorate degree, I went out to Illinois, and they were doing research on establishing which of the 20+ amino acids were essential for health. That was work being done by a Professor Rose, and the graduate students who were doing this research would talk with me.
I was doing a structure proof at the time, but I learned an awful lot by taking courses as a post-doctorate fellow for two years. To make a long story short, I came up with this idea that if one would concentrate on nutrition based on the fasting blood levels of the essential amino acids, one could get some profoundly important results. And so, when I left Illinois and went to work in the drug industry, as fate would have it again, I was able to convince the people in Washington to allow one of our men from Pfizer, where I worked, to do some research on testing the idea. And it was that idea that led to the first patent in 1963.
Now here I am working for Pfizer. They’re interested in brand new drugs. They were not interested too much in making nutritional supplements, so as a result, I sort of studied this without a lot of fanfare; did careful research, and then many years later after I left Pfizer, I joined the faculty of St John’s University to be a professor. I stayed there until I retired in 1987, and when I retired I did full time research. This research led to three additional patents. The last patent was issued in December 2007. That’s my educational background and how I got interested in supplementation of amino acids, in order to avoid high blood sugar and so on.
Janet: It’s your personal family history that really initiated it, but over your career, fate, as you mentioned, has put you at the right place at the right time.
Dr. Charles Jarowski: Absolutely.
Janet: Now we have statistics telling us that 25% of the American population are either diagnosed as diabetics, have diabetes and don’t know it, or they’re pre-diabetic, and over a million new cases are diagnosed each year. What would you say are some of the causes of this epidemic in the American population, and, is it a crisis, is it a health crisis that we’re facing?
Dr. Charles Jarowski: Well, we have to look behind it. Americans, as you know, generally have a breakfast that’s prepared in a hurry. Many people, if they have to drive or catch a train to work at 7:00 am, may be riding in a car, and they’re munching on a Danish, a muffin, or some kind of an easy thing to eat, with a cup of coffee. They get out of the car, get on the train, finish their breakfast, and off to work they go. Now, almost all Americans who consume cereals, in one form or another, should realize that almost all cereals contain rather high concentrations of carbohydrate. So we get into this pattern of a breakfast which is loaded with carbohydrate, and what happens then? Our blood sugar surges upward.
When I did my research on myself, I used rice. When I use rice and heat it for 3 minutes or so in a microwave oven, my blood sugar goes up to 290! Now, my son is a doctor, and a very good doctor, an internist, and he told me,”Dad, you are a ripe individual to get Type II Diabetes. Look how high your blood sugar goes after a simple meal of rice, milk, and egg white.” And so as a result, when I began to do my research, I looked into the composition of the proteins that I was consuming, and I felt if I could make sure that I blended some amino acids that would make that protein more completely utilized, I would probably be able to lower my blood sugar.
So, I think most of Americans eat cereals containing sugar, and a lot of young people like sugar-coated cereals, and when we take a cup of coffee, a lot of people have to have one or two teaspoons full of sucrose. So, we’re into a habit of loading our body with high concentrations of carbohydrate.
Now interestingly enough, after the research went on for some time in my case, I was able to develop a blend of 4 amino acids that would make the food that I ate be more completely converted to desirable protein in my body and not have excess amino acids - that are actually currencies for our bodies. Young people, of course, eat even larger quantities of carbohydrate, are not worried about their blood sugar, and build up high concentrations of carbohydrate.
If you really want to know the effects on your body, though, you should measure your blood sugar after a simple meal. And, if you don’t mind pricking your finger and reading it with a glucose measuring device, you would know for yourself that a particular meal may not be very useful.
Clearly, obesity is a very big problem in America today. People keep saying we should go on diets, exercise more, and so on. But I think that when you look at a situation; here my dad, at age 69 lost a leg, my sister at age 69, and here I am 90 years old and still walking on two feet. And I think to myself that I wasn’t so brilliant to do that; I just actually took a look at the biochemical literature.
When you read through and find out what I learned by reading this material, that amino acids, if you eat a large meal - more than you should eat - your body doesn’t just urinate out the excess amino acids. Your body reabsorbs them, and as a result you have amino acids going back to the liver. If the liver cannot use the aminos that are in excess, you will convert them to carbohydrate like glucose, and what happens is people gain weight, they damage their system by having these molecules flowing through their blood circulation.
Janet: I think it probably is an eye-opening statement for a lot of our listeners to hear that the components of protein, the amino acids, if they are not properly metabolized and utilized in the body, this excess of amino acids actually is converted into sugars, different forms of sugars. Because over the years, people have been told that if they reduce their carbs, particularly the simple carbs in their diet, and they eat a higher protein diet, then their risk of destabilizing their blood-sugar chemistry is reduced. What you’re saying, if we eat too much, if it is a large meal, even if it’s a high protein meal and does not contain the simple carbohydrates, it is still possible that you can elevate your blood sugar.
Dr. Charles Jarowski: That’s correct Janet, that’s correct.
Janet: You mentioned measuring your blood sugar after a simple meal. What might be a level that would be in a danger area; what might be an acceptable blood sugar level after a simple meal, and how long after the meal should you wait to measure your blood sugar?
Dr. Charles Jarowski: Well, you know, I always tell people – especially when I’m giving a lecture before a group of people - you don’t have to believe the biochemistry. Everything is true, but you can prove it to yourself very simply. For example, if I eat a breakfast on Monday, on Tuesday I have the same breakfast and take one capsule before I eat. Then, I measure my blood sugar each day 10 minutes after I’ve finished my breakfast. If I don’t see a dramatic change, then either one of two things; either my breakfast was low in carbohydrate, or I actually have a very active pancreas that makes enough insulin.
In my case, I take rice, milk, and egg white, heat that together and have it for breakfast. 10 minutes after this breakfast, I measure my blood sugar without supplementation. Without GlycoTrol, my blood sugar reaches 290. Now if you talk to people who are experts in the Diabetic Society, they say keep your blood sugars below 160. Another group, endocrinologists in our country, say we should keep our peak blood glucose under 140.
As I said before, here’s the thing that’s so sad, that people do not realize. The body does not just urinate out excess amino acids. It is true that if you eat a protein meal, with no carbohydrate in that meal: eggs, bacon, whatever, things like that, you will now get very low elevation of blood sugar in the body after 10 minutes of consumption of that meal. However, if you eat a lot of that type of protein, what happens is your body does not utilize all of it. It is slowly converted to carbohydrate in the body enzymatically.
Now the bad thing about using protein meals to reduce blood-sugar is that if you eat a lot of protein, what happens is the nitrogen-containing amino groups are converted to byproducts, and these by products can be very bad and very toxic if your kidneys do not function properly. You end up with high levels of urea and ammonia and uric acid.
Now the point I want to make is this: many people that I’ve talked to - who have gone on these high protein diets - tell me that urination was very painful. There was a burning sensation when one urinated because of these byproducts coming out in very high concentrations. So, my conclusion is, eat intelligently, but use the supplement before your meal.
The thing about this now, Janet, that is so interesting is that amino acids by themselves will stimulate the pancreas to make insulin. If your insulin is being produced satisfactorily, and you want to stimulate your pancreas to secrete more insulin, amino acids will do it.
However, when you use the four essential amino acids that are lacking in the typical protein meals that we eat in our country, what happens is not only do you stimulate the pancreas, but you also more completely convert the protein that is in your meal to desirable products in the body like albumin, and gamma globulin and so on.
Janet: Um, very, very important information for our listeners, Dr.Jarowski, and what we’re going to do is take a short break right now on Healthline, and when we come back, we will discuss those four very, very important amino acids that are found in Lidtke GlycoTrol and find out how we can go about very, very successfully balancing blood sugar chemistry. To our listeners, you’re tuned to Healthline. I’m Janet Simorelli. I’m here with Dr. Charles Jarowski, and he is the formulator of the product we’re talking about, GlycoTrol, for the maintenance of healthy blood glucose, cholesterol, BUN, and triglycerides.* We’ll be right back after these messages.
*Already within a normal range
Janet: Just before the break, we were talking about the amino acid component in GlycoTrol. Dr. Jarowski, tell us a little bit about those four amino acids and why they are in this formula.
Dr. Charles Jarowski: To take one example, tryptophan is limiting in many of the proteins that we eat, and tryptophan is a very important amino acid in order to make more of the protein you consume be utilized properly, so you don’t have a lot of amino acids left over that can’t be made into albumin and gamma globulin, for example. Those proteins both contain tryptophan.
And if you don’t have enough tryptophan in your diet, if you’re eating a protein like a piece of pork or beef or whatever, or fish, you find out that you will be short of tryptophan as the limiting amino acid, it would be nice if you had a little more present in the form of a GlycoTrol capsule.
Now, when you add more tryptophan, you make protein better, more valuable, a more completely utilized protein. Now, after you satisfy the tryptophan requirement, if you look at the rest of the composition of the protein and the fasting blood, you say, it would be nice to make that even better still by adding some lysine, another amino acid. And, indeed, you will find that to be the case. When we did our research at the National Institute of Health, way back in 1963, in that era, we actually showed that we could get much better growth of laboratory rats by having amino acids that would make that protein better balanced. So, the grouping of lysine, tryptophan, valine, and methionine, was developed by making the protein more completely balanced, more completely utilized, and as a result we used that in our GlycoTrol formula.
Our approach was to analyze 60 proteins that are commonly consumed, the vegetable protein, animal protein, eggs, milk, things like that that are actually in our daily diet in America, and we found out that when we looked at the composition of these proteins, these four amino acids would improve the protein that we’ve consumed. In other words, after consuming a meal, you find out the urea level is lower, and you find out the blood sugar’s under control if you use the supplement.
What I want to emphasize is that my wife and family and I, and now my grandchildren, have been using GlycoTrol for over 20 years. We have never had any side effects; we never had any upset stomachs, and our blood chemistry is in excellent health.
On the other hand, Janet, if I stop taking this supplement before each meal, what happens is my triglycerides will go up. With the same type of meal, my triglycerides will go up to about 240mg %. And if I go back on supplementing, my triglycerides drop down to 110. If I stop taking the supplement for a month, and measure my cholesterol levels, they go up to about 180mg %. When I go back on the supplementation, they go back to 122.
I strongly believe, not only in the effectiveness of the supplement, but in the safety as well. All the 7 ingredients, 3 vitamins and the 4 amino acids, are in your body all of the time, even without eating breakfast. Analyze your blood, and you will find these 7 ingredients there.
Janet: It’s very interesting because in your newsletter, it talks about these four amino acids, when they’re present in sufficient numbers, sufficient amounts, then the possibility of the excess amino acids being converted into sugar and changing your blood sugar level is significantly reduced. What role do the combination of Vitamins B6, B12, and folic acid play?
Dr. Charles Jarowski: They’re important, and the reason I included them in my research was that I knew there was a great interest in methionine possibly converting to homocysteine. Actually, more recent literature says that methionine may not be a risk factor, but the use of the vitamins is not a bad idea because they are very useful in protein synthesis, anyway.
Janet: Now, it’s true that GlycoTrol is very, very easy to take.
Janet: Now I’m really getting so much out of this discussion with you Dr Jarowski, and I’m looking forward to the response from those individuals out there that I know have had a great deal of difficulty in balancing blood sugar chemistry, despite having very great focus on their quality diet, despite using the substances that they’ve been educated about from the natural realm that are meant to balance blood sugar chemistry. Talking about those people who have been diagnosed as diabetic and using medication, are they able to use the GlycoTrol in addition to their medication?
Dr. Charles Jarowski: Now, the way I look at it is this: when friends of mine, and people that I meet when I go to give a seminar, ask me the very question that you raise Janet, I tell them that since I do not take any drugs at all, there would be no way for me to give personal experience, but I do know a few cousins of mine that have used GlycoTrol in addition to drugs, and it hasn’t hurt them at all. I told them that they could try leaving out the drugs and see what happens over a 2 or 3 day period, and a few of my cousins that tried that actually stopped taking the drugs because they found that GlycoTrol and diet helped them maintain their blood sugar level.
Usually, the peak level occurs right after a meal. When the body has not consumed any food at all, the blood sugar stays at a rather lower level. Now when you eat a meal that is not a proper meal for you, and you don’t have protection against the surging blood sugar, then you will have high levels that last for a few hours.
You may think, “Well, it’s going to come down; why be concerned about it?” One of the things that is being overlooked, though, is if you have a high concentration for two or three hours, the glucose molecules have a tendency to react with hemoglobin. Hemoglobin is in the red blood cells flowing through your body, and glucose actually interacts with the hemoglobin. The result is a compound called hemoglobin A1C. What happens is those molecules are stable in the body about 4 months! They’re not useful to have around because they’re now bigger molecules attached to glucose, and they flow around in your body, and they damage your kidneys, they damage your eyes, and as a result people should be concerned if their blood sugar is high for too long a period.
As a matter of fact, like I mentioned earlier, it’s not good to even get over 140, say the endocrinologists, and it shouldn’t get over 160 says the American Diabetic Association, because they’re worried about hemoglobin A1C.
Now, one last thing Janet, if you’re cheating on your doctor, and you’re now eating sweets, and you go back to the doctor and he’s checking you, and he says, “Janet, I can tell you haven’t been following my recommendation of cutting back on carbohydrates.” And you say, “How do you know that? For the last two days, protein is all I’ve had.” He says, “Yes, but you were really hurting yourself by eating a lot of carbohydrate a few weeks ago because these things that form in your body stay around for 4 months before they get completely destroyed by the body enzymes.”
So, high blood-sugar is a bad thing to have for long periods of time. If you don’t eat, your blood-sugar drops because your body uses it - like we use gasoline for a car - as the body’s energy. But if you now are taking too much, then you cause these side reactions to occur, and as a result, you can only in time find that you have hurt your eyes and your kidneys and your liver. So, to answer your question, high blood-sugar should be under control. Diet-wise, you should be worried about it.
One thing I didn’t mention to you before is something I found interesting both in my case and my wife’s case. She wanted to join me when I did some of this research about 20 years ago, 15 years ago. So, we decided that since we were going to use a capsule before each meal, before breakfast, before lunch, and before dinner, we would not eat between meals. We thought it would be stupid to use high carbohydrate containing meals if we were trying to keep our levels under control. So, following that dietary regimen, no snacking, eating carefully and not between meals, we lost weight. I lost 35 pounds. And interestingly enough, you’ll get a kick out of this; I went from 185 down to 155, which was my weigh when I got married 63 years ago.
Al Foreman: God bless you.
Janet: Happy Day!
Dr. Charles Jarowski: And it has stayed at that level, even with Thanksgiving, having a lot of turkey, my weight may go up 1 or 2 pounds, but then I check myself after I go on my normal regimen. It’s 155, 154, 156. It stays in that area.
Janet: Sounds fantastic!
Al Foreman: Think about one question Dr. Jarowski. What effect does GlycoTrol have on low blood sugar?
Janet: Al, just before the break, you were asking about those people with low blood sugar. Are they able to help balance blood sugar levels with GlycoTrol? Dr. Jarowski, what do you have to say about that?
Dr. Charles Jarowski: I would simply say this: only one person that I’ve met, a friend of mine, had a daughter who suffered from low blood sugar. In my own judgment, it may not be any use at all for those people because it will stimulate the pancreas to make more insulin, and if you now are going to be making more insulin, you control blood sugar. It would seem to me it could actually make the condition worse for that person if they have very low blood sugar. Very low blood sugar would mean that they usually have low energy, but I have very little experience with it.
As we all know, people with low blood sugar actually lose their coordination. They kind of walk wobbly, almost as if they’re inebriated. And if someone overdoses themselves with insulin, maybe forgets they already took a shot, and takes another injection of insulin, you can’t tell the difference between him being over-intoxicated with alcohol or blood sugar. They stagger as if they’re inebriated. So I can only say (this is a long-winded way to answer you) that I don’t know if it would be useful, and I would imagine it would have to be very carefully done in order to be sure you weren’t hurting somebody, making it even worse.
Janet: What about someone who has a family history of diabetes, but so far their blood sugar testing shows them to be in the normal range, should they begin to use GlycoTrol?
Dr. Charles Jarowski: I think it has a multiple usage. Not only will it help them maintain normal levels of glucose in their body, but they also will get better utilization and conversion of their protein intake into useful protein in the body. What people may not realize, but what animal studies have shown, is that if you take a dog, for example, and feed him food containing a radioactive carbon in, say glycine, which is a non-essential amino acid, or maybe even in valine, an essential amino acid, that dog will manufacture cholesterol with a radioactive carbon in it. That would mean that by feeding an animal imbalanced amino acids in the form of protein, you can produce cholesterol, you can produce triglycerides, you can convert the amino acids to glucose. It’s an amazing thing! So, the body has a wonderful factory, but it’s so versatile, that if it has extra building blocks flowing around through the body, it can convert them to highly desirable complicated protein structures, and also take these products and convert them to undesirable metabolites as byproducts of enzymatic breakdown.
Janet: After people begin using GlycoTrol, what should they look for? What should they monitor?
Dr. Charles Jarowski: Well, if I were making a recommendation to start out, let them simply measure their blood sugar after the same meal, two days in a row, using GlycoTrol a few minutes before one of those meals. I personally try to do it after 10 minutes because it peaks very rapidly if I have a rapidly absorbed meal, like heated rice meal.
It would seem a good idea to check it 10 minutes after a meal, ½ an hour, an hour, and see what happens. If they see that they’re in good shape and that the GlycoTrol is benefitting them, well they can say it’s not deleterious to their health. All I can tell you is that intelligent eating has to accompany this. If you’re eating a massive amount of carbohydrate, it’s very tough for the body to control that. Someone I’m sure wouldn’t do that.
Janet: And we are almost out of time. I want to let our listeners know, that if they’d like to speak to someone at Lidtke Technologies, they can call toll free, 800-404-8185. Dr. Jarowski, thank you so much for joining us. It has been absolutely a world of very high quality information for all those people suffering with unstable and elevated blood sugar. Thanks for joining us.
Dr. Charles Jarowski: Thank you, and you’re welcome!
Janet: And to all of our listeners, thanks so much for tuning in. Remember Healthline is here every Monday, Wednesday, and Friday 11-12noon. Thanks for tuning in. Bye bye everyone.
Dr. Charles Jarowski: Bye now.

At Lidtke, we manufacture nutritional supplements that are kind to your body and your soul – using only the richest, cleanest natural ingredients that we test ourselves for impurities.
In everything we do, we strive to restore life and health, and we value and honor those who share our philosophy.
Our mission is to educate, enlighten, and share our knowledge base with everyone in our community, and we encourage all of our customers to do the same.
Many dream about making the planet a better place – only a determined few dedicate their lives to actually making it happen.
When it comes to nutritional supplements, there are hundreds of details that must be controlled to attain the highest quality, and as a manufacturer you truly have to believe in your work to spend decades refining the procedures and identifying the best suppliers needed to achieve such high goals.
We, at Lidtke, are a specialty manufacturer and in order to live up to our philosophy, we take the time to understand each ingredient so that we can discern small but important differences in quality.
As worldwide levels of radioactive nuclides, heavy metals, solvents, pesticides, herbicides and GMO ingredients continue to increase, the challenge to live a healthy life, we believe, becomes a worthwhile priority.
Be well in mind, body, and spirit!
At Lidtke we are concerned about contaminants, the kind of organic and inorganic chemical contaminants, including solvents, fumigants, and heavy metals, that you may find in foods or supplements.
A few of the chemicals identified include acetone, toluene, hexane, ether, 1,2-dichloroethane, ethyl acetate, isopropyl alcohol, and ethylene oxide. These chemicals may, unknown to the bottler or consumer, be used in manufacturing processes.
Generally, nutritional ingredients are tested only for a few contaminants, and the other, untested toxic solvents, fumigants, pesticides and herbicides can be hundreds of times higher than safety standards.
The average consumer, in fact, would be surprised how often such solvents and other chemicals are used in the manufacture of “natural” products. Toxic residues such as these are more commonly found in low-cost nutrients because manufacturers can dramatically reduce their expenses by leaving out critical purification steps. Sorry to say, such residues seldom can be detected by consumers, and their illnesses, years in the future, may never be diagnosed.
These are the reasons why we believe it is important to work with respected suppliers of ingredients and raw materials – those who share our commitment to purity and safety. Please feel free to mail us your suggestions!
