Best L Tryptophan Supplements For Anxiety And Sleep 2019

By Kenny Lee | Essentials

Jul 25

Dietary balance is important in regulating our emotion. L-Tryptophan, an amino acid crucial for our mental health is turning out to be a popular supplement for reducing anxiety. However, before you start taking L-Tryptophan to make up for the lacking amino acid in your body, it is wise to understand the potency and precautionary measures of this compound.

What Is L-Tryptophan?

L-Tryptophan is an essential amino acid needed by the body to regulate our emotional wellness, such as preventing over anxious respond and calming our mind from stress. However, L-Tryptophan is not produced in the body and is only available by consuming protein in plants and meat.

Turkey is one of the commonly cited sources of L-Tryptophan but is often linked to drowsiness that follows. Here are other L-Tryptophan-riched foods where you can derive the essential amino acid.

  • Seeds & Nuts
  • Soy Bean
  • Cheese,
  • Lamb, Beef & Pork
  • Chicken
  • Salmon
  • Oats
  • Eggs

If your regular diet is missing these L-Tryptophan enriching foods, you stand the risk from suffering from anxiety, depression or bouts of insomnia. This is because L-Tryptophan is eventually converted to serotonin, melatonin, and vitamin B6. Serotonin is an important hormone that helps balance your mood while melatonin ensures a regular circadian sleep cycle for you.


How L-Tryptophan Helps Anxiety

You may have realized that our brain is an ultra-complex network of billions of brain cells. These tiny cells are connected by neurotransmitters to transmit messages to each other.  Serotonin is a major neurotransmitter that provides neural-pathway for the tiny brain cells.

The lack of serotonin has been linked to an increased in anxious thoughts and overreaction to stress. When you’re under a distressful situation, your the serotonin level in your brain reduces, and fight-or-flight hormones like adrenaline are produced in excess.

Some people suffer from serotonin deficiency and that results in anxious behavior. As serotonin is one of the components converted from L-Tryptophan, it becomes a common suggestion that taking the L-Tryptophan supplements can help to reduce anxiety.

This suggestion is not unproven. In fact, a clinical study where 25 participants are given a high intake of L-Tryptophan diets shows a decrease in anxiety and depressive symptoms after four days.

What happens when you take L-Tryptophan is that the amino acid is converted into 5-HTP, an amino acid precursor that is later broken down into serotonin, melatonin and vitamin B6. This is how the necessary hormones are produced for reducing anxiety and sleep.


Other Health Benefits Of L-Tryptophan

Those who lack L-Tryptophan and suffering from anxiety has a clear benefit of taking this essential amino acid. But there are other health benefits that are associated with L-Tryptophan.

  • It Helps With Depression – L-Tryptophan is equally effective in reducing depressive disorders as it is with its equally crippling cousin, anxiety. The increase in serotonin as the L-Tryptophan is broken down proves to be effective in lifting a depression-stricken person’s mood.
  • Reduces Severity Of Migraines – Migraines can ruin the day of a perfectly energetic person. The pulsing one-sided headache has long been linked to the low level of serotonin. Taking L-Tryptophan boosts serotonin level and thus helps reduce the occurrence and severity of migraines.
  • Helps With Sleep Disorders – Besides serotonin, L-Tryptophan is also converted into melatonin. Melatonin is a sleep hormone that is naturally produced when the body senses a dark surrounding. It helps to prepare the body and mind for sleep. Therefore, taking this essential amino acid can help in regulating your circadian cycle.
  • It Promotes Weight Loss – L-Tryptophan is not your miracle weight loss pill, but it plays an important role to ensure your body metabolism is at its optimum level. Besides helping your weight loss regime, it also ensures that you experience less fatigue and increased endurance.
  • It alleviates pain: L-Tryptophan is also linked to improving pain tolerance when taken orally.
  • Reduces Pre-Menstrual Dysphoric Disorder: Studies have pointed to the positive effect of L-Tryptophan in reducing PMDD, a debilitating physical and emotional symptoms that affect women severely.

How To Take L-Tryptophan Safely

L-Tryptophan supplements may be one of the most potent remedies for reducing anxiety, but taking it at an incorrect dosage can cause serious side effects. It is sold as a supplement and not as a drug. As such, there are no standards in determining the dosage although 500 mg is regularly recommended for a regular supplement.

If you’re taking L-Tryptophan to address your anxiety or other health issues, the following table provided by the University Of Michigan will be helpful.

  • Insomnia: 1-2 grams at bedtime
  • Depression or anxiety: 3-6  grams a day
  • Pre-Menstrual Dysphoric Disorder: 2 to 6 grams per day, during the second half of the menstrual cycle

L-Tryptophan is sometimes taken for addressing other health issues. If you’re in doubt of the right dosage of L-Tryptophan, always consult your doctor for clarifications.


Precautions and Side Effects Of L-Tryptophan

Unlike some supplements, L-Tryptophan can cause serious side effects when taken in an extreme dosage or when taken with certain medications. In 1990, there are cases of individuals developing eosinophilia-myalgia syndrome (EMS) and suggestions that they are linked to L-Tryptophan supplement.

While there is a suspicion that suggests the cases are attributed to contaminated L-Tryptophan products, it results in a massive recall of the amino acid supplements.

Overdosing of L-Tryptophan leads to a condition termed as Serotonin Syndrome. This causes physical symptoms of irritability, fever, sweating, fluctuating blood pressure, and irregular heart rate. Prolonged Serotonin Syndrome can lead to death. Therefore, it is always mandatory to consult your doctor if you’re doubtful of the right dosage.

L-Tryptophan should never be used together with medications for depression and sedative depressants as such combination can result in severe side effects. Individuals who are suffering from kidney or liver problems and eosinophilia should refrain from taking L-Tryptophan.

There is insufficient research to suggest the safety of L-Tryptophan for pregnant and breastfeeding women. It is recommended that expecting women and lactating mums should stop taking L-Tryptophan.


How To Choose The Right L-Tryptophan

Considering the potency of L-Tryptophan, you wouldn’t want to choose the cheapest supplement that you come across on the shelf. Instead, it pays to evaluate these factors before making a decision.

  • Dosage – The first consideration is the dosage of the L-Tryptophan. While you’ll want the dosage on the safe spectrum, you do not want it to be too weak to bring any benefits. A minimum of 500 mg commonly recommended for a regular supplement.
  • Safety And Purity – Manufacturing and testing are two important elements that determine the purity, potency, and safety of the supplement that you received. Certifications like cGMP, Gluten-Free or third-party tested are bonus points.
  • Manufacturer Reputation – You want to buy your L-Tryptophan supplements from manufacturers that have a proven track record. Thanks to the internet, you’ll get to read reviews on some of the manufacturer’s website, and that will give you a general idea of the quality of the products.

Where Can You Buy L-Tryptophan

While L-Tryptophan is usually sold at local pharmacies, many consumers are turning to online suppliers to get the supplement. You can visit the reputable supplement manufacturers that sell L-Tryptophan on their online store, or try to get better-priced products at Amazon. Besides, you get to compare reviews to determine the best L-Tryptophan product for you.
