What is L-Tryptophan?
L-Tryptophan (or just tryptophan), sometimes referred to as ‘the calming amino acid’, is an essential amino acid that our bodies need to be healthy.  Amino acids are the building blocks of proteins, and essential amino acids are especially important because our bodies cannot produce them. This means we have to get them from our food. In addition to forming an important part of many proteins, L-Tryptophan is used to make other important molecules in our bodies that have a variety of functions, including regulation of sleep and mood.
Is There a Difference Between Tryptophan and L-Tryptophan?
Tryptophan comes in two varieties: L-Tryptophan and D-Tryptophan. D-Tryptophan is rarely found in proteins, and does not get converted into melatonin or serotonin.  Because of this, L-Tryptophan is what you’ll see on the markets. See the #1 L-Tryptophan Supplement now A D-Tryptophan supplement would be extremely rare and would not be beneficial.
Why Should I Take It?
L-Tryptophan is considered a dietary supplement. This means that you should take L-Tryptophan if you don’t get enough in your regular diet. Many people have trouble getting enough of this amino acid from normal foods, and find that their bodies suffer many side effects from this deficiency. Below are listed a few of the conditions that may be exacerbated by a tryptophan deficiency, and that many people use tryptophan to relieve.
- Mood disorders
- Trouble sleeping
- Sleep apnea
- Facial pain
- Premenstrual Syndrome 
Remember that L-Tryptophan is not a cure for any of these conditions, but it does reverse some common problems that result from a dietary deficiency. If not getting enough tryptophan in your diet contributes to you having any of these problems, a tryptophan supplement could be the solution. See the #1 L-Tryptophan Supplement now.
How Does It Work?
Your body uses many complex molecules for signaling and regulation. Many of these molecules can be hard for your body to make so it employs a shortcut: it makes them from relatively complex molecules like tryptophan that are already very similar in structure. Although this is an effective way for your body to churn out hard molecules to produce, it also means that a deficiency in your diet can have compounded negative effects.
Our bodies use tryptophan in this way. We turn it into melatonin, which aids sleep, and serotonin, which has a variety of functions, including helping with mood regulation. Many people have trouble getting enough tryptophan in their diets, but when you take tryptophan supplements, your body is more able to produce melatonin and serotonin. That’s why people with chronic sleep and mood issues, or who suffer from low melatonin or serotonin levels more specifically, can benefit from taking additional tryptophan.
Is It Safe?
Yes! L-Tryptophan is considered safe by the FDA as a dietary supplement.  In addition it is part of a normal diet, although many find it hard to get enough through just their food. L-Tryptophan isn’t just safe, it’s an essential part of your diet.
I’ve Heard the FDA Recalled L-Tryptophan?
L-Tryptophan is safe and natural. In the 1980’s, one foreign importer of tryptophan used an unsafe process to refine it which resulted in a contaminant (often referred to as Peak E) that increased the risk of a condition known as EMS, or eosinophilia-myalgia syndrome. This resulted in FDA restrictions on the import of tryptophan supplements. In 2001 the FDA relaxed many of its restrictions as the unsafe processes used in the past had been identified, traced to its source, and stopped.  In other words, tryptophan is now produced in a completely safe way. Getting Tryptophan from supplements is safe as long as you follow your supplement manufacturer’s instructions and general common sense.
What Dose Should I Take?
The best advice is to follow manufacturer instructions. If your product is sold legally in the United States the dosage should be safe. The US Food and Nutrition Board recommends 5 mg/kg of body weight (roughly 5mg for every 2.2 pounds), and many manufacturers recommend a dose around 500mg of the raw supplement for adults.  Each company will package its supplements differently, so the number of pills or amount of powder that contains this dosage may vary. Make sure to check the packaging for more information. If the brand shows a range of doses you can take, it’s always best to take the smallest effective dose. This means you should start with the lowest recommended dose and increase the dose until you get the desired effect. Never take more than the highest recommended dose.
Can I Take It with Other Supplements?
Yes. Tryptophan is found in the food you already eat. That means if you take anything else approved as a dietary supplement you already are receiving tryptophan in your diet with the other supplements you take. If you follow dosage instructions for all the products you use, tryptophan is safe to take with other dietary supplements. See the #1 L-Tryptophan Supplement now
Can I Take It with Medications?
Because tryptophan is found in many foods, it is usually not considered problematic when taken with medications. Some scientists suspect that it may interact with certain drugs, but these interactions are only suspected and not well known or studied.  You should ask your doctor if you have any questions, or are pregnant or breastfeeding and plan to take L-Tryptophan. If you experience any unwanted side effects with L-Tryptophan, as with any supplement, you should stop taking it and talk to your doctor.
What are the Side Effects?
Tryptophan can have several side effects. Side effects are rare for people consuming proper amounts of tryptophan, but some people report higher sensitivity to tryptophan than others. Below are some of the side effects that are commonly reported from taking tryptophan supplements:
- Strong heartbeat/palpitations
- Loss of muscle control
- Muscle stiffness
- Blurred vision
- Head twitching
- Drowsiness or fatigue
- Dizziness 
- Eye twitching 
As with all supplements, discontinue use and consult your doctor if you experience any unwanted side effects, and never use more than the recommended dosage. See the #1 L-Tryptophan Supplement now
L-Tryptophan or 5-HTP?
Our bodies naturally convert tryptophan to melatonin and serotonin. Part of the process involves converting it first into 5-hydroxytryptophan, or 5-HTP. Because of this many report very similar effects from both supplements. If your problem is tryptophan deficiency, a tryptophan supplement may not only work fine, it might also be cheaper. If tryptophan doesn’t seem to be working, consider the possibility of using a 5-HTP supplement with your doctor.
L-Tryptophan or Melatonin?
Because our bodies use L-Tryptophan to make melatonin, many report similar results for both. Just like with 5-HTP, if your problem is tryptophan deficiency, and not another problem with the production of melatonin, a tryptophan supplement may not only work fine, but it’ll probably also be cheaper. If tryptophan doesn’t seem to be working, you might want to talk to your doctor about using melatonin.
L-Tryptophan or Seratonin?
Tryptophan is used for many many things inside our bodies, and another one of those things is to produce serotonin. Because of this, many report similar results from both. Just like with 5-HTP and melatonin, if your problem is tryptophan deficiency, rather than a problem with your body using serotonin or a problem in the production of serotonin besides tryptophan deficiency, a tryptophan supplement may not only work fine, it might also be much cheaper than another product designed to increase serotonin levels. If tryptophan doesn’t seem to be working, consider the possibility of using another medication with your doctor.
L-Tryptophan and Other Products
Occasionally you’ll find someone on the internet who’ll tell you that tryptophan works in place of their prescription sleeping or mood medications, like Xanax. Although this sounds like a dream come true for many, L-Tryptophan has not been investigated by the FDA to validate these or other claims of its treatment capability. Always consult your doctor before replacing a prescription medication. See the #1 L-Tryptophan Supplement now
What Should I Look for in My L-Tryptophan Supplement?
For many people cost will be the primary issue. If you’re going to be using this for a while you don’t want to be spending an arm and a leg. But don’t overlook issues of quality. Shop around for a low price for your supplement that doesn’t compromise purity or potency. Here’s an easy trick you can use: if you divide the total cost of your supplement by the serving count, a competitive price is between 12 and 16 cents per serving (not including any shipping costs).
After you find a few providers that offer tryptophan at a good price, start comparing the quality of the supplements themselves. When comparing different supplements, ask around (or ask the manufacturer) if each product you’re considering is tested for quality by a third party. Usually this is a good indication that the manufacturer is producing a reliable product. That way you know you’re getting a the kind of supplement you want.
Here’s one last but simple thing to look out for: be sure you’re getting the type of tryptophan you want. If pills are easier, make sure you buy a pill. If you want a powder, make sure that’s what you buy and that a serving scoop is included. It sounds simple, but you’ll find a lot of people overlook this and end up causing themselves a lot of unnecessary frustration.
What Other Ingredients are Sometimes Added to this Supplement?
Common ingredients in capsules and pills include gelatin (for the capsule), silicon dioxide and rice flour (to fill in any empty space), and magnesium stearate (commonly used as a lubricant)  . These are generally recognized as safe and you shouldn’t worry too much if you see this on the ingredient list. If you are vegan you’ll want to avoid gelatin since it can be made from animal products.
Search for an option with veggie capsules or that’s powdered. One other common ingredient, Piperine, is also normal in supplements. Piperine has been shown to aid in the absorption and retention of certain substances, including tryptophan.  If you see other ingredients it’s always wise to do a little research and find out what they’re used for. Also, make sure the tryptophan is present in the amount you want (see “What dose should I take?” above). Sometimes the actual amount of tryptophan in a product is small because so many other ingredients are added, which means you end up paying more than you want for the same effect.
