L-Tryptophan Supplement Supports Healthy Sleep and Mood
Tryptophan Supplement product image

Intended for:

  • Relaxation and sleep*
  • A calm mood*
  • Appetite (cravings) for carbohydrates*

Tryptophan

is a natural building block of serotonin, the neurotransmitter that plays an important role in appetite, mood, normal sleep patterns, and nervous-system function.*

Serotonin has become a goldmine for the makers of patent medicines, but there are two vastly different approaches to making your body think it has more serotonin: one is to mimic it, the other is to make it.*

With LIDTKE® L-Tryptophan there really is no better, no more-natural way to feel relaxed.*

Here is what one of our customers had to say about their experience with our tryptophan:

I ran into a small store in Thatcher, AZ and found your product. I normally used another brand of Tryptophan and they were out. So I bought yours. I tried it and I am hooked! This stuff works great!

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.

5.0 out of 5 starsHighest Quality L-Tryptophan, December 17, 2013
Amazon Verified Purchase(What's this?)
This review is from: Lidtke Technologies - L-Tryptophan 500 mg. - 120 Capsules (Health and Beauty)
One thing you gotta know about L-Tryptophan is this: Buy high quality or DON'T buy at all! Seriously. Just go read some of the reviews on the cheap Source Naturals brand as just one example. Guys, these are REAL incidents that have happened to REAL people. Be very, very cautious what brand you pick. Your health matters. If you go the cheap route you just might be one of the unlucky ones with a horror story and end up having to pay big bucks in medical bills to treat the symptoms caused from it. Obviously, if that happens, in the end you will not be saving money by buying low quality. Better safe then sorry.

I take 2 of these before going to bed and they help me to get sleepy. I prefer not to take them during the day because of that. They are a bit hard to swallow because they aren't as heavy as other capsules I've had, and tend to float on top of the water in your mouth instead of sinking.

This review is from: Lidtke Technologies - L-Tryptophan 500 mg. - 120 Capsules (Health and Beauty)
LIDTKE is one of the best products on the market. Seriously, it's like the Rolls Royce of products. That's pretty much all they do, and that's all they need to do. Anyone who wants to sleep better, be happier in mood and attitude, and see life brighter should consider this product. It's practically Pharmaceutical grade. You cannot get this in a typical grocery store or CVS or Walgreens at least in California - this is the real deal. Got to get it directly from source. It's simply the best, nobody disputes Lidtke's quality.

This review is from: Lidtke Technologies - L-Tryptophan 500 mg. - 120 Capsules (Health and Beauty)
Trad sleep meds do not let you rest as they interrupt sleeping patterns. This one gives you good rest. There are various areas of the brain that natural sleep things help regulate. I use L-tryptophane for when I am on adrenalized "ON". It regulates it back to peace. I use whole herb Valerian for when thoughts race to slow that. I use melatonin IF I need to change when I get to sleep moving from time zone to time zone. These natural assists have been fabulous in getting me back fully resting.

I have a lot of trouble unwinding and shutting my brain off at night in order to fet some sleep. Thought I would try this natural product to help me do that. I found that it works very well. I plan on buying again.

5.0 out of 5 starsExcellent product!!!, July 26, 2013
Amazon Verified Purchase(What's this?)
This review is from: Lidtke Technologies L-Tryptophan 500mg 60 caps
I give this product a 5, firstly because I was impressed by the companies care of using excellent clean product and secondly because the product works.

I was using anti - depressants and found when I came off them I would fall back into depression.
With L-Tryptophan I started to sleep better and think positive. My depression changed to a positive outlook and happy disposition.

I have now stopped using L-Tryptophan for a month and my moods are still positive and strong. I keep a bottle by my bedside for those times when I do feel stressed or down which has been minimal because I seem to snap out of the sadness/depression.

5.0 out of 5 starsAmazing product ~ outstanding quality, August 23, 2010
This review is from: Lidtke Technologies L-Tryptophan 500mg 60 caps
I did not purchase this through Amazon or an Amazon Seller, however I must tell you that Lidtke products are more expensive because they are of excellent quality. This particular formula is wonderful, simply because you don't need to add the other minerals and supplements and guess at correct measurements and ratios. At one time, when Lidtke was first introducing the "Complete" formula, they offered a generous free sample of the product. After the sample of six capsules arrived, I took one capsule. I'd been living with a lot of anxiety at the time and taking a moderate dose of Valium each day to keep the stress I felt from becoming overwhelming. Thus, I was hoping for good results but was truly skeptical.

About 30 - 45 minutes after swallowing a single capsule, I was so mellow, I nearly nodded out at the computer and fell out of my chair! I felt such profound relaxation, it was as though I was blissfully stoned. A feeling of comforting warmth and well-being enveloped me from head to toe. I took a second capsule and carefully made my way to the bedroom, where I had the most gorgeous, luxurious sleep. Lidtke Complete almost immediately enveloped me in a sense of serenity and happiness. My mood was instantly uplifted from irritable and stressed to pleasant and dreamy.

This has been a consistent experience I've had with this brand and formulation. You simply have to try it to believe it! Lidtke does have their own web site, where you can read materials online and request that literature be mailed to you. Sometimes they offer specials. I recommend having a look... you will receive a very thorough education and understand precisely how this formulation works. And when I say I was skeptical, please know I was convinced that nothing could surpass a Benzodiazepine.. I was stunned by how potent L-Tryprophan Complete is -- and what is additionally superior is that this product elevates mood and is not addictive. It is much better and kinder than SSRI antidepressants because you are not selectively blocking reuptake of serotonin, thus keeping more of it around. You are actually creating more of this mood-enhancer, rather than "recycling" the amount of serotonin that's already in your brain. When you are suffering from depletion, the SSRI antidepressant will take some period of time to work and may and may not be optimal for you.

With this supplement, in my experience, the effects are nearly immediate and there are none of the annoying side-effects so often associated with SSRI medications. Of course, if you are taking any prescribed SSRI or SSNRI, you put yourself at risk by using L-Tryptophan ~ too much serotonin can be life-threatening: you must choose one or the other and titrating down from a pharmaceutical antidepressant is not a quick and easy accomplishment. Do not *ever* attempt to simply stop taking a prescribed antidepressant if you've taken it for a month or more ~ get on a titration schedule approved by your Doctor.

To continue, I later purchased Lidtke's Complete formula through a health food store in a town where I lived. They stocked only one of the Lidtke products, one used for chronic pain which apparently was effective ~ this store carried many items based strictly upon customer requests and demand. I needed to make a special order and wait a few weeks until the store, which had a limited operating budget, would have enough requests for Lidtke products to obtain an order at discounted or wholesale prices.

In the meantime, I sought a workable substitute: thus, I would rate "Source Naturals" L-Tryptophan as a good substitute for Lidtke's pure L-tryptophan, but you will need to add at the very least vitamin B-6 (ideally, those who are stressed use the activated co-enzyme formula of B-6 known as P-5-P) to create the necessary conversion of L-tryptophan to 5-HTP in the brain, rather than in your bloodstream. The objective is to create a fresh supply of serotonin within the brain and not create potential for serotonin syndrome. Source Natures also makes a combination formulation, but I have not tried it. I would guess, based on the very good quality of their L-Tryptophan that it is also a good substitute: like a Cadillac compares to a BMW. Both are luxurious and powerful. One is slightly more luxurious and powerful than the other.

And no, I have not found any manufacturer's 5-HTP ever to be a superior means of achieving relaxation and elevated mood (and again, I always add B-6), even though it is a less expensive and more direct way of elevating serotonin levels. There is something in the conversion process which enhances relaxation. And I've never been able to achieve the Great Mood and gorgeous peace that I have with the L-Tryptophan Complete.

I'm impressed and pleased to find Lidtke products available through an Amazon Seller...quite convenient, as just one of the three health food stores in the nearest "big city" that requires a 60-mile round-trip stocks a few of the Lidtke products, but none of them are the "Complete" formula and this store actually marks these products with a price that's higher than full retail (!). As I said, the cost of Lidtke products are typically more expensive, but there is a real reason for this which has nothing to do with "snob appeal". Quite simply, you are paying for true pharmaceutical-grade products and each batch is tested to ensure the batch meets their high quality standards.

You can safely find very good equivalents from Source Naturals and often pay substantially less ~ but once you've experienced the Lidtke product, you will feel a bit let down even by that which is very good. The difference is obvious to me: one is trustworthy, high quality and gets the job done; the other does that and takes you quickly to Nirvana, as well. Those of you who would prefer not nodding out and being enveloped by a feeling of incredible peace may prefer to use Source Naturals, which will help you to relax and sleep and incrementally improve your mood. Whatever you choose ~ enjoy!
