Aspartame vs. Phenylalanine: What's the Difference?
Edited by Sawaira Riaz || By Sumera Saeed || Updated on November 16, 2023
Aspartame is an artificial sweetener, while phenylalanine is an amino acid and one of the components of aspartame.
Key Differences
Aspartame is a low-calorie artificial sweetener used as a sugar substitute in many foods and beverages. It is made synthetically by combining the amino acids aspartic acid and phenylalanine. Phenylalanine, on the other hand, is a naturally occurring essential amino acid found in various foods and is also used by the body to produce proteins and other important molecules.

Phenylalanine is one of the building blocks of proteins and is important for the production of other amino acids and neurochemicals in the body. Aspartame, after ingestion, is broken down in the body into its constituent amino acids, including phenylalanine, which can be problematic for individuals with phenylketonuria (PKU), a metabolic disorder.

Aspartame is often used by individuals looking to reduce their caloric intake or manage diabetes because it is about 200 times sweeter than sugar and does not raise blood sugar levels. Conversely, phenylalanine is used by the body in a wide range of physiological processes, including the synthesis of tyrosine, another amino acid, and neurotransmitters like dopamine and norepinephrine.

While aspartame is subject to regulatory scrutiny and debate regarding its health effects, phenylalanine is a well-understood component of the human diet, necessary for normal growth and maintenance of life. Aspartame consumption needs to be monitored by those with PKU due to the presence of phenylalanine, which they cannot metabolize effectively.

Aspartame’s inclusion in food can often be identified by a warning label indicating its presence, primarily for the benefit of those with PKU who must limit their intake of phenylalanine. While phenylalanine is essential and safe for the general population, aspartame's safety has been a topic of discussion, although approved by many health authorities.
