L-phenylalanine is the natural form of Phenylalanine (Phe). Phenylalanine is an essential amino acid, a building block of many proteins and a precursor to tyrosine and thyroid hormones.1 The word “essential” means that the body cannot synthesize it and therefore Phenylalanine must be included in the diet. Phenylalanine is naturally found in many foods, including eggs, fish, chicken, pork, nuts and cheese. Nowadays it can also be obtained as a dietary supplement for healthy cognitive function.
L-phenylalanine appears to influence the synthesis and release of dopamine, epinephrine and norepinephrine (collectively called catecholamines) neurotransmitters in the brain.1 All of these neurotransmitters play an important role in optimizing cognitive functions, such as memory, mood, mental energy and alertness.
Upon ingestion Phenylalanine is easily absorbed and transported to the brain where it crosses the blood-brain barrier (BBB) and is then converted to neurotransmitters.
The recommended daily dosage of L-phenylalanine is 600 mg.
L-Phenylalanine is generally considered to be a safe and well-tolerated dietary supplement. However, the recommended dose should not be exceeded as it may lead to some side effects, including headaches. L-phenylalanine supplements are not recommended for pregnant women, people with high blood pressure and those taking monoamine oxidase inhibitors (MAOIs).
