Best L-Tryptophan

L-tryptophan is one of the eight essential amino acids necessary for good health. It’s a building block for proteins and neurotransmitters needed for a variety of bodily functions, including regulating sleep and mood. Our health sufferers if we don’t get enough of this amino acid.

As L-tryptophan isn’t made by the body, it must be obtained from diet and supplementation. Some high-tryptophan foods include:

  • Meat
  • Fish
  • Dairy products
  • Eggs
  • Nuts and seeds
  • Nuts and seeds
  • Potatoes
  • Oats
  • Bananas
  • Chocolate

Health Benefits of L-Tryptophan

Creates Niacin

We need to consume sufficient L-tryptophan to manufacture niacin (vitamin B3) in the body. We need niacin for energy production, healthy metabolism, heart health, skin health, nervous system health and much more.

These compounds protect the body from damage caused by free radicals that we encounter due to cellular reactions, stress, pollution and poor diet and lifestyle. By scavenging free radicals, antioxidants relieve chronic inflammation and may prevent premature aging and chronic disease.

Promotes Quality Sleep

L-tryptophan is key for the production of serotonin and melatonin, two hormones necessary for sleep and relaxation.

Melatonin is released in the evening and regulates our circadian rhythm — the body clock that tells us when to sleep and wake up. Instead of replacing melatonin through a supplement, L-tryptophan allows the body to efficiently make its own supply.

Several studies have shown that L-tryptophan supplementation reduces how long it takes to fall asleep and increases the amount of time spent in the crucial deep, restorative sleep stage.

Taking L-tryptophan is a promising alternative to sleep medications that can have dangerous side-effects and cause drowsiness the next day. It’s a game-changer because getting quality sleep is the best thing we can do for our health, energy and mood.

Boosts Exercise Performance

L-tryptophan is great for athletes and exercise-enthusiasts because, like many amino acids, it’s involved in muscle building and strength.

Interesting studies on sportsmen have found that L-tryptophan supplements increase performance, endurance and total exercise time. The mechanism behind this is L-tryptophan’s ability to increase pain tolerance by boosting serotonin levels.

Regulates Mood and Improves Behavior

L-tryptophan is a calming amino acid that produces and regulates serotonin — a mood-boosting neurotransmitter that reduces irritability, depression and anxiety. It works by producing a precursor to serotonin, called 5-hydroxy tryptophan (5-HTP).

Research shows that low levels of L-tryptophan — and therefore reduced serotonin production — increases the risk and symptoms of mood disorders. On the other hand, high-tryptophan diets and L-tryptophan supplementation have been shown to boost mood and relieve depression and anxiety.

Studies have shown L-tryptophan can also:

  • Improve seasonal affective disorder (SAD)
  • Increase socially constructive and agreeable behavior
  • Reduce argumentative behavior

It has also been shown to lower systolic and diastolic blood pressure, likely a side-effect of regulated insulin and blood sugar.

Relieves Premenstrual Syndrome (PMS)

Low levels of L-tryptophan have been associated with monthly PMS symptoms, especially low mood and irritability. By increasing serotonin levels, L-tryptophan supplements may help to decrease mood swings associated with PMS and a severe form of PMS, called premenstrual dysphoric disorder (PMDD).

A 1999 study gave women with PMDD 6g of the amino acid for 17 days a month over three cycles. They had significant reductions in stress, irritability and mood swings.

Optimizing L-Tryptophan Absorption

Other amino acids compete with L-tryptophan for absorption, so it’s best to take L-tryptophan supplements away from high-protein foods. Consume it with whole food carbohydrates that promote insulin release and encourage its absorption across the blood-brain barrier.

L-Tryptophan Precautions

L-tryptophan raises serotonin levels in the brain but if they increase too much, it can lead to “serotonin syndrome.” Symptoms include sweating, tremors, anxiety, racing heart and muscle spasms. Speak to your doctor before taking L-tryptophan if you’re on chronic medication for depression or anxiety.
