Quality and value...

LIDTKE Technologies' L‑Tryptophan Complete^TM uses the same IV medical-grade L‑Tryptophan found in all our L‑Tryptophan products.

L‑Tryptophan Complete^TM also contains significant amounts of essential cofactors, coenzymes and newly-understood ingredients that are known to modulate L‑Tryptophan pathways.

About LIDTKE Technologies...

LIDTKE Technologies was founded 13 years ago to provide rare and extremely high-quality nutrients to medical doctors, naturopaths, veterinarians, and alternative health practitioners throughout the country.

Due to the emergence of the internet, word of LIDTKE products spread to the general public, and we now supply both health practitioners and the general public in the United States and in over twenty-five other countries.

ew L‑Tryptophan Complete takes L‑Tryptophan a step further. In recent years, our research has revealed the importance of numerous biochemical pathways that are part of L‑Tryptophan metabolism.

There are many steps to L‑Tryptophan metabolism, and each of these steps is controlled by an enzyme within your cells. Each enzyme, though, is as useless as a car without wheels if it lacks the critical coenzymes and cofactors that make it run.

Our job has been to identify and quantify these coenzymes and cofactors, and combine them in L‑Tryptophan Complete to ensure your cellular enzymes work, and you receive all the benefits of L‑Tryptophan that Nature intended.

L‑Tryptophan Complete was inspired by the fact that many peoples around the Earth are so poorly nourished they fail to get proper benefit from the food or supplements that they do receive. Even in prosperous countries, genetic variations and unwise diets can interfere with your metabolism of essential nutrients.

Understanding many of these human differences, our intention at LIDTKE for many years has been to create an L‑Tryptophan formula that works even when a host of health issues and deficiencies may be present.

The fact is, thousands of health-conscious consumers are now benefiting from L‑Tryptophan Complete. They use it and depend on it for better health.

Anxiety and Panic Attacks

by Heather Jenson

y anxiety started many years ago very mildly and very seldom. At that time I would get a little dizzy and my heart would race, not really understanding what it was. When I went to the doctor(s), I informed them about what I was experiencing, so they put me on Xanax.

I was taking Xanax for quite a few years, before I would go out in public and sometimes before bed. It was actually helping me a lot; I didn’t experience any major anxiety for a long time. Unfortunately, there came a time in my life that I stopped taking the Xanax and stopped caring about myself. I just gave up on everything and anything that I ever cared about. When times got really bad, I experienced some things that turned my anxiety into full blown panic attacks. 

Experiencing a panic attack for the first time was one of the scariest things I have ever experienced. You do not even feel it coming on and all of a sudden you feel like you are going to die. The dizziness, the blurred vision, the rapid heart beat and the hyperventilation were all signs that I was about ready to faint. After I started having these panic attacks, I finally made it back to the doctor. That is when they put me back on drugs. 

The drugs worked, but they weren’t good for me. Xanax is highly addictive, and with my addictive personality I had to choose another route. 

About 11 months ago, I started taking 2 L‑Tryptophan Complete before I went to bed and weaned myself off of my prescribed meds. Immediately my mind stopped racing and I could fall asleep right away. My night terrors were limited and I could finally sleep without waking up in fear.

My anxiety was still pretty bad throughout the day, and I didn’t want to take the L‑Tryptophan Complete because I figured it would make me tired, and I wouldn’t be able to get things done. Finally, after many weeks of my heart racing and constantly coughing, I decided to try taking 1 L‑Tryptophan Complete. About 10 minutes after taking it, my coughing was gone and my heart rate slowed down. I was slightly tired, but it was no where near what a drug made me feel like, and I seemed to actually focus better, since I was more relaxed. It is truly a great feeling to know that I have a solution for my anxiety when it creeps up on me. Drugs are not an option for me today.

Thank you for reading my story, and I wish you all the best!

A message from LIDTKE

r. David William, who writes the popular health newsletter, Alternatives, brought L‑Tryptophan to the attention of his subscribers way back in 1996. And just as his loyal fans have grown, so have the many thousands who take L‑Tryptophan on a daily basis.

If you are unfamiliar with L‑Tryptophan, it is naturally found in protein and has been recommended by nutritionally-educated doctors in America and Europe for over thirty years.

To show you the importance of this critical amino acid, L‑Tryptophan is commonly added to baby formulas because it is essential for growth. Moreover, L‑Tryptophan is added to hospital intravenous solutions (IV’s) where it is absolutely essential to life.

You should be aware that your body does not make L‑Tryptophan, and you cannot live without it.

Many of our clients: Psychiatrists, medical doctors, and nutritionists, alike, have long recognized the value of L‑Tryptophan for maintaining good health, promoting a cheerful mood, relieving irritability, reducing the craving for sweets and carbohydrates, and encouraging normal, healthy sleep.

Although L‑Tryptophan is an essential amino acid commonly found in protein, it is important to understand that L‑Tryptophan also is the amino acid most lacking in your diet. Plasma amino-acid analysis of hundreds of patients demonstrates that L‑Tryptophan is the amino acid most deficient in the American diet.

As demonstrated by Dr. Charles Jarowski, former head of Research and Development at Pfizer, Inc., when an essential amino acid such as L‑Tryptophan is in short supply, a host of health conditions begin to surface, often emotional ones, first.

Remember, because L‑Tryptophan is an essential nutrient, no other amino acid, protein, vitamin, mineral, herb or drug can take the place of L‑Tryptophan.

How are your serotonin levels?

With so many articles being written about the importance of serotonin and the use of serotonin-mimicking drugs, not everyone knows that L‑Tryptophan is the only, natural building-block of serotonin, the natural brain chemical that helps you remain calm, yet focused.

Countless research articles document the fact that serotonin reduces anxiety, promotes a cheerful mood, promotes restful sleep, and reduces the craving for carbohydrates, sweets, and other fattening foods.

L‑Tryptophan, being an essential nutrient, provides so many benefits, in fact, they are hard to number. For example, one metabolite of L‑Tryptophan may increase zinc absorption. Patients with zinc and vitamin B6 deficiency often experience severe inner tension, anxiety and phobias. According to Dr. Eric Braverman in The Healing Nutrients Within, “These patients do well with L‑Tryptophan supplementation.”

Dr. Braverman continues: “A sixteen-year-old boy came to us with a history of vandalism, violence and aggression. We started him on 2 gm of L‑Tryptophan am and pm… One month later, the patient returned, having been transformed from a wolf to a lamb. Slowly, for the next two months, we tapered his dose to 2 gm daily, without reappearance of symptoms.”

With American’s consuming so much protein, it might seem unlikely that L‑Tryptophan could be in short supply, but it is true. Furthermore, as established in Research done by Richard and Judith Wurtman at the Massachusetts Institute of Technology (MIT), high-protein diets actually interfere with L‑Tryptophan absorption by your brain, where it is most needed for mental and emotional health.

According to an article in the journal, Psychosomatics, the high-protein, low-carbohydrate diets so common today may actually be aggravating anxiety disorders, such as panic disorders. Unfortunately, anxiety disorders are frequently treated by doctors unfamiliar with nutrition, who prescribe drugs that only mask the problem, rather than solve it.

If you have ever been under the dark cloud of “mood-enhancing” drugs, you already know some of the side effects. Dr. David Sussman, quoted in Clinical Psychiatry News, lists the short-term side effects of nausea, diarrhea, headache, and agitation. Long-term side effects – even more important due to the often long-term nature of such disorders – include, among others, “insomnia, weight gain, sexual dysfunction…”

As noted by Dr. Linus Pauling, PhD, two-time winner of the Nobel Prize, our first approach to healing should be to find the right molecule or nutrient to repair health, not a drug to hide the problem.

The problem may be as simple as not enough L‑Tryptophan reaching your blood stream.

Remember that L‑Tryptophan is not a drug and does not work like a drug. L‑Tryptophan is a natural, building-block of health that thousands of consumers around the world supplement their diet with every day.

Patients who have been misdiagnosed and are experiencing the side effects of SSRI’s or other serotonin-mimicking drugs should know that they have a natural alternative.

Many who are deficient in L‑Tryptophan and who suffer anxiety disorders may experience improvement in just a few weeks… although we do recommend allowing sixty days for full benefits. In either case, you receive the same, no-questions, LIDTKE 100% money-back guarantee.

To try a no-risk, one-month supply of L‑Tryptophan or L‑Tryptophan Complete (we recommend L‑Tryptophan Complete for anyone who may not be receiving a full range of vitamins and chelated minerals) simply click below and order.

LIDTKE L‑Tryptophan Complete is a patent-pending formula designed to ensure that you receive the most benefit from L‑Tryptophan. You cannot buy better quality than LIDTKE.

Remember the LIDTKE guarantee, and give L‑Tryptophan Complete a try… from the people who care enough to do it right!

by R.G. Sturtz, M.S.

A favorite buzz-word in the nutrition field is “enzymes.” What is seldom mentioned, though, is the fact that different enzymes work in different parts of your body. Digestive enzymes work in the gastrointestinal track, but digestive enzymes do nothing to keep your cellular furnaces burning and producing energy. The fires in these furnaces are ignited by cellular enzymes. It is cellular enzymes, then, that keep every one of your trillions of microscopic locomotives running.

The second fact that is largely ignored is the importance of “cofactors” and “coenzymes.” An enzyme is helpless without them. Cofactors and coenzymes are small molecules - often vitamins or minerals - that attach to an enzyme and are as essential as wheels on a car. An enzyme will just sit and do nothing without them.

This brings us to an important principle: It is simply impossible to supplement the many thousands of enzymes that produce all of your energy and create all of your neurotransmitters (such as serotonin). So, we need to look for other ways to boost these enzymes. The good news is that by scientifically combining cofactors and coenzymes in a supplement, we can greatly enhance the effectiveness of our own enzymes.

How do we know which co-factors and co-enzymes to take?

L‑Tryptophan, like all other amino acids, follows biochemical pathways that consist of dozens of steps. With this in mind, research conducted at LIDTKE has mapped nearly all of the L‑Tryptophan pathways, their respective enzymes, and the cofactors and coenzymes that make those enzymes work. We have found that the proper addition of specific nutrients to L‑Tryptophan can not only enhance the production of desirable metabolites, but also reduce the production of incompletely metabolized waste products.

Serotonin has been a key focus of pharmaceutical companies and the pharmaceutical-approach to depression for years. First, MAO inhibitors came along. MAOI's slow the breakdown of serotonin, but also increase blood levels of tyramine, creating the risk of a severe increase in blood pressure that can lead to a stroke.

Building on the laundry list of side effects, the Tricyclics and much later the "miracle drug" SSRIs (such as Prozac/Zoloft) hit the market. Both classes of drugs recycle serotonin over and over. L‑Tryptophan, on the other hand, is the natural precursor to serotonin, and the only such nutrient that normally occurs in your diet. Just as important, and in stark contrast to "miracle drug" chemicals, is the fact that your body was born with the biochemical machinery to process L‑Tryptophan completely and without side effects.

Hundreds of research papers emphatically prove that supplemental L‑Tryptophan increases serotonin levels in the brain. Less well-known, though, is the fact that only a small percentage of ingested L‑Tryptophan goes down the brain serotonin pathway. Increasing that percentage even a fraction can provide a dramatic boost to brain serotonin levels. A simple boost in serotonin has helped millions experience restful sleep and brighter, happier moods than many have enjoyed in years.

Actually, L‑Tryptophan travels down several very beneficial pathways. Most-importantly, though, to sufferers of insomnia, depression and eating disorders, if all the proper cofactors/coenzymes are present, L‑Tryptophan travels from the blood stream to serotonin-sensitive neurons where it converts to serotonin. Brain messages of satiety (fullness) and well-being can then be sent without interruption. On the other hand, if certain enzymes are inactive - due to a lack of cofactors and coenzymes - L‑Tryptophan can be diverted down the kynurenine pathway and converted to niacin or to the mildly-toxic quinolinic acid.

For the scientists among you... inside the serotonin-sensitive neuron, L‑Tryptophan and tetrahydrobiopterin (abbreviated BH4) combine to form 5-Hydroxy L‑Tryptophan, the first step in the L‑Tryptophan-to-serotonin pathway. Well-funded researchers in university laboratories have found that BH4 actually increases the flow down the serotonin pathway. Although it doesn't take much BH4, the astronomical cost of $4 million per kilogram will keep BH4 out of the reach of nutritional supplements. Fortunately, the researchers at LIDTKE have found a combination of nutrients that increases the natural levels of BH4 at a far more affordable price.

The second step to serotonin production requires Vitamin B6... but not just any, cheap Pyridoxine Hydrochloride (HCl) will do the job. Serotonin-producing enzymes can only use Vitamin B6 in the form of Pyridoxal 5-Phosphate (P5P). While pure P5P costs far less than $4 million per kilogram, it is still ten times more expensive than the Pyridoxine HCl usually found in nutritional supplements.

Although most individuals can convert some dietary Pyridoxine HCl to P5P, knowledgeable researchers have voiced concern that incompletely converted Pyridoxine HCl may actually block the benefits of the true form of vitamin B6. Hence, LIDTKE L‑Tryptophan Complete uses only genuine Pyridoxal 5-Phosphate, the kind your body uses.

In short, the full complex of cofactors and coenzymes included in L‑Tryptophan Complete maximizes the conversion of L‑Tryptophan to serotonin, but at LIDTKE that is not enough. Very recent research shows that curcumin, the same curcumin that reduces cancer risk in experimental animals, also helps reduce the breakdown of serotonin into inactive metabolites. Curcumin in L‑Tryptophan Complete, then, helps ensure that the serotonin your body creates will be available when your body needs it.

L‑Tryptophan Complete maximizes serotonin both coming and going. By increasing production of serotonin directly within serotonin-sensitive neurons and by reducing the break-down of serotonin, L‑Tryptophan Complete becomes a powerful, fast-acting agent for the relief of insomnia, depression, anxiety and a multitude of stress-induced maladies of our age. Whether you are overcome by the stresses of home or the business world, whether your individual biochemistry is ideal or whether you suffer from an imbalance, L‑Tryptophan Complete is the finest answer on the market. Feel better, sleep better. Be at peace in body, mind and spirit.

"I just wanted to say thank you for putting out such a great product. Your tryptophan has literally saved my life. About 25 years ago, I was in a car accident where I fell asleep at the wheel and crashed. Ever since then, I have not been able to fall asleep. That is until my mind is totally exhausted. I have that defensive syndrome where if I am falling asleep and I hear a noise that startles me awake, I am up for hours. About 3 years ago, my wife heard your ad on the radio and took a chance and purchased your tryptophan for me. Well, that was a chance well taken. I have been taking Bios tryptophan every night and in doing so I am guaranteed sleep. Those of us who have gone through years of sleep deprivation will be forever grateful to you for the quality of your products. As I said before, you literally saved my life and I for one will be forever grateful. Thank you. All the best,"

"I have been taking L‑Tryptophan for my great difficulty with sleeping for at least 20 years. I am a 90 year old man and have been purchasing your L‑Tryptophan and your True B6 "P5P" since 1997. I would like to say you have a very good firm to deal with.

My doctor had recommended L‑Tryptophan for me to take at night, 2 capsules before bedtime every evening. This product works much better than the drug "Prozac". For one thing, L‑Tryptophan has many more benefits and uses than Prozac, and it is an all natural product that is non-addictive. I have had friends that had children on Prozac that committed suicide. I am a strong believer in L‑Tryptophan!

I have been recommending your company and the L‑Tryptophan for years to my friends as well as my family. My children use your company's L‑Tryptophan as well as my grandson. It helped my grandson when he was going through a very nervous period in his life. After using this supplement he was able to sleep, it calmed his nerves and he was able to study. I am a CPA, and my son that is also a CPA uses your L‑Tryptophan during tax season when it is very stressful. He says he is as good as new thanks to this product!

I have heard L‑Tryptophan has been around for 100 years and I will continue to use it indefinitely."

"Absolutely wonderful company and excellent customer service. Bios L‑Tryptophan is truly a life saver for me. It is an amazing product that calms me down and sends me off to sleep with none of the nasty side effects that you would get from traditional drug-based sleep medication. L‑Tryptophan gives your body what it needs and the results are quite dramatic...works on me within 30-40 minutes. Also I notice I feel calmer and happier the next day after taking it..Fantastic!.. Thanks Bios!!!!

I want to tell you that your L‑Tryptophan has been a miracle for my mother who is 81 and has not slept well since she was 17 years old. She is not only sleeping, but I have never seen her so happy. This has changed her life and we thank you!

You do not know how this has effected me also since I feel so relieved with her new sleeping pattern. She now has more energy than me! That's why I want to use the product also. I want to feel as good as my mother and I am 30 years younger!!

Thanks, again,"

"L‑Tryptophan has been the most effective treatment I have found for depression and manic depression, and believe me I've tried them all. I suffer no side effects, and can move through life with zest and energy, yet relax when it is time to wind down. During the years that Tryptophan was unavailable, I suffered, trying every prescription medication and reeling from side effects or breakthrough symptoms. Thank you for continuing to make the best Tryptophan available."

"The LIDTKE Technologies L‑Tryptophan has allowed me to avoid taking an SSRI for anxiety and panic attacks. I have been taking it for about 3 weeks now at the maximum dosage on the bottle and I have seen a gradual improvement during this time. I would highly recommend it for anyone whose life is being controlled by anxiety. I can function again!! Thank you LIDTKE Technologies!"
