What is Phenylalanine?
Phenylalanine is one of nine essential amino acids, meaning the body needs it to sustain life but cannot
produce it. Instead, it relies on dietary sources like dairy, eggs, meat, soy products, and supplements to
meet its phenylalanine needs. Phenylalanine is a critical precursor to tyrosine, another amino acid, which
converts into L-DOPA. The body needs L-DOPA to synthesize the neurotransmitters epinephrine, norepinephrine,
and dopamine. The food and beverage industry uses phenylalanine to produce the artificial sweetener
Potential Phenylalanine Benefits
Phenylalanine and Mood
Phenylalanine may boost mood by increasing dopamine levels. Dopamine is known as the feel good
hormone and directs behaviors using rewards as motivation. When the brain anticipates a reward, it triggers
a dopamine drop and pleasurable feelings. Unsurprisingly, low dopamine levels can cause low moods and
correlates with many mood disorders. Researchers have also linked low phenylalanine levels with mood
Phenylalanine and Skin
Some individuals experience an unexplainable loss of skin pigmentation when their pigment-producing cells
stop functioning or die. The loss of color results in white patches that may make some individuals feel
self-conscious. Research shows that taking phenylalanine supplements combined with ultraviolet light therapy
improves skin pigmentation dramatically. Another study reported similar findings but used a skin gel and
regular sunlight exposure in lieu of ultraviolet light therapy. Researchers believe phenylalanine achieves
this result because it is the precursor to melanin, the substance that provides pigment to the skin, hair,
and iris of the eye.
Potential Phenylalanine Side Effects
Most individuals can take phenylalanine supplements without serious side effects, and the FDA granted it
generally recognized as safe (GRAS) status. Individuals taking schizophrenia medication should not take
phenylalanine supplements. Individuals with phenylketonuria (PKU) should not take phenylalanine supplements,
as their bodies cannot metabolize phenylalanine.
