It is used in electrolyte infusions to treat heart and liver disorders and is explored for supporting recovery from fatigue.

The most common form, L-Asp is a "proteinogenic" amino acid used to build enzymes and tissues. It is central to the urea cycle , helping the liver detoxify ammonia, and plays a key role in the malate-aspartate shuttle , which helps cells generate energy (ATP).

Acetyl aspartic acid is an active ingredient in anti-aging products used to firm and lift the skin. Health and Supplementation

Aspartic acid, also known as , is a non-essential amino acid that serves as a vital metabolic hub within the human body . While it is often simplified as a basic protein building block, its actual biological utility spans from energy production to neuroendocrine regulation and industrial manufacturing. Biological Roles and Forms

D-Asp has shown promise in improving sperm quality and fertility rates in men, though results for muscle building are generally inconclusive.

Its derivative, polyaspartic acid, is used as a biodegradable fertilizer enhancer to improve crop yields and nitrogen absorption.
