Product Details

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 aspartame.

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 disorders.

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.
