What is L-Tryptophan Complete?

L-Tryptophan Complete is the result of years of research into the brain's many natural biochemical pathways, with the goal of maximizing healthy levels of serotonin.* L-Tryptophan encourages:

  • Restful sleep*
  • Improved mood, less irritability*
  • Relief of minor aches and pains, such as pain resulting from exercise, and*
  • Helps curb an excessive appetite (craving) for carbohydrates*

However, how tryptophan is utilized in the body can depend upon a number of factors, such as the availability of certain vitamins and nutrients. It is for those who seek to maintain healthy serotonin levels and who wish to improve their nutritional balance of this essential amino acid that L-Tryptophan Complete was developed.

The normal production of both Serotonin and Melatonin from L-Tryptophan depends on numerous enzymes - some of which are part of the L-Tryptophan > Serotonin pathway, and some of which are not. Each enzyme in this process depends, in turn, on specific cofactors and coenzymes. Without these, an enzyme is like a car without wheels, and the biochemical pathway may function poorly or become a dead end - forcing metabolites down alternative pathways that may produce side effects.

Getting the right nutrient to the right enzyme is the key.* Once in your cells, L-Tryptophan can follow many pathways. The challenge is to encourage and direct L-tryptophan to follow the one branch that leads to serotonin.*

Lidtke has studied these pathways and has identified numerous cofactors and coenzymes that we believe will help maintain healthy serotonin levels, for a brighter outlook and a more productive life.*

When you look back at the diet of prehistoric peoples, paleo-anthropologists tell us that the average intake of folic acid (not methylfolate) was approximately 5mg per day, far above the amount found in dietary supplements today.

Dr. Weston Price traveled the world visiting many tribes and groups of people who still consumed diets very similar to the diets common to ancient man. Almost without exception, those people were far healthier than those consuming a modern diet.

At Lidtke, we have searched far and wide for a form of folate that approximates the form found in the diet of ancient man. The best that we have found is the Organic Lemon Peel Extract which we now provide in all of our products that require folate. We see no contraindications for the use of this ingredient.

Methylfolate on the other hand may bypass our natural methylation feedback controls and may be contraindicated for a portion of the population who are prone to elevated methylation. Lidtke strives to benefit the widest population possible, and for this reason we have chosen to use our Organic Lemon Peel Extract as a source of folate.

We realize that some labels posted to the internet may be obsolete, and we are working to replace them with our most current labels.

Is there anything I should avoid when using this product?

There are three primary classes of drugs that you may want to avoid when taking L-Tryptophan. Conversely, when taking these prescription drugs, you may want to avoid L-Tryptophan supplements. These drugs include: SSRI's, Tricyclic's, and MAOI's. L-Tryptophan by itself behaves in a predictable way, and serotonin levels tend to respond as L-Tryptophan consumption increases.

These classes of drugs, though, operate in less predictable ways, and mixing L-Tryptophan with any of them could raise serotonin levels higher than desired. If you are working with a physician and would like to reduce your drug dosage in favor of taking a natural supplement, please have your doctor review The Hunter Serotonin Toxicity Criteria, available online. It is our belief that numerous doctors have used this protocol with good results.

This review is from: Lidtke Technologies - L-Tryptophan Complete 120c (Health and Beauty)
It works the only problem I encountered is that it takes 3 to do the job, and the capsules are large. I drink a lot of water afterwards but always feel as though I have at least one stuck in my throat. I wish this came in a tablet or a chewable form. If anyone has suggestions on making it easier to swallow please let me know. I have tried eating something afterwards, but it is inconvenient to take them about 1/2 hour before I intend to go to sleep and then go downstairs to get a piece of bread or something to help push the capsules down. I watch TV late at night and find that it takes about 30 minutes for these to work, but then they work great.

This review is from: Lidtke Technologies - L-Tryptophan Complete 120c (Health and Beauty)
A friend of mine who runs a substance abuse detox center in Sedona told me he only trusts this brand. They have very high standards for quality and purity of product. My friend says he can see a difference in his clients between this brand and others. This product contains complementary supplements that support the processing of L-Tryptophan. It's obvious they've done their homework. Everything they claim - the inclusion of B vitimins, the importance of taking the product with little or no protein, etc. - I've been able to corroborate by researching elsewhere. Check out their website - Lidtke Technologies - it's full of useful information. I've come to trust their claims. I wouldn't say this about the vast majority of supplemental health products or companies.

This review is from: Lidtke Technologies - L-Tryptophan Complete 120c (Health and Beauty)
I was looking for a natural alternative to sleeping medication and researched my options and decided on Tryptophan Complete because it is a natural pathway in my nervous system that maintains and sustaines seratonin levels. I have no trouble falling asleep and get complete rest without being groggy in the morning.
