Aspartate vs. Aspartame — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on March 22, 2024
Aspartate is an amino acid involved in the body's metabolic processes, while aspartame is an artificial sweetener derived from aspartate and phenylalanine.

Key Differences
Aspartate plays a crucial role in the urea cycle and neurotransmitter synthesis, contributing to the body's protein synthesis and energy production. On the other hand, aspartame is a low-calorie sweetener used in many sugar-free and diet products, offering sweetness without the high caloric content of sugar.
Aspartate is naturally occurring in the body and in various foods, including meats, grains, and dairy products, where it functions as a building block for proteins. Aspartame, however, is synthetically created and used primarily as a food additive to enhance sweetness without adding bulk or significant calories.
The consumption of aspartate is generally considered safe and necessary for health, as it supports numerous bodily functions. Whereas the consumption of aspartame has been a topic of debate, with concerns over its safety and potential health effects, although regulatory agencies consider it safe for most people when consumed within limits.
Aspartate can also act as a neurotransmitter in the brain, playing roles in the nervous system's functioning. Aspartame, after ingestion, is broken down into its component parts, including aspartate, but its consumption does not significantly affect neurotransmitter levels due to its low concentration.
While aspartate is vital for health and involved in many metabolic pathways, aspartame's role is primarily as a dietary substitute for sugar, aimed at reducing caloric intake and managing weight or blood sugar levels.
