L-phenylalanine is the natural form of Phenylalanine (Phe). Phenylalanine is an essential amino acid and a precursor to tyrosine and thyroid hormones.2 “Essential” means that Phenylalanine must be included in the diet as it cannot be synthesized in the body from other precursors. Some of the best natural sources of Phenylalanine are eggs, fish, chicken, pork, nuts and cheese.
L-phenylalanine is a building block of many proteins, enzymes and brain chemicals. L-phenylalanine influences the rates of synthesis and release of dopamine, epinephrine and norepinephrine (collectively called catecholamines) neurotransmitters.2 The synthesis of neurotransmitters has been shown to be directly dependent on the brain concentrations of their precursor (i.e., L-phenylalanine).1 Dopamine is a unique neurotransmitter with both excitatory and inhibitory properties. For example, dopamine helps with depression, regulates mood and enhances mental alertness.
Other reported benefits following the use of L-phenylalanine include improved memory, boosted energy levels and even reduced chronic pain. Due to its ability to relieve pain, some users take L-phenylalanine to treat migraines and other headaches. On the other hand, symptoms of Phenylalanine deficiency include confusion, lack of energy, depression, decreased alertness, memory problems and lack of appetite.3
The recommended daily dosage of L-Phenylalanine appears to vary widely from 100 mg to 2000 mg. But it is not recommended to take more than 2000 mg/day.
Upon ingestion Phenylalanine crosses the blood-brain barrier (BBB) and enters the central nervous system where it is converted to neurotransmitters that start to elicit their effects.
L-Phenylalanine is generally considered to be safe and well-tolerated. However, you should not exceed the recommended dosages (see above) as you may have negative health effects. Overconsumption of L-Phenylalanine may cause headaches, hypertension and anxiety. L-Phenylalanine are not recommended for pregnant women, people with high blood pressure and those taking monoamine oxidase inhibitors (MAOIs).
