What is L-Aspartic Acid?

L-Aspartic Acid (LAA) is the L-form of the amino acid Aspartic Acid. It's a non-essential amino acid, meaning the body can produce enough of it on its own without needing to obtain it from dietary sources. It can also be synthesized from ornithine and citrulline in the urea cycle.

Where Does It Come From?

L-Aspartic Acid is predominantly found in plant proteins as well as a few animal sources, such as:

  • Soy Protein

  • Avocado

  • Oysters

  • Wild game

What does it do?

Aspartic acid plays a crucial role in generating cellular energy and combating fatigue. Aspartic acid moves the coenzyme nicotinamide adenine dinucleotide (NADH) molecules from the main body of the cell to its mitochondria. Here, it's used to generate ATP (adenosine triphosphate), the main molecule that provides energy for all activity within a cell.

More available NADH means more fuel can be produced by each cell leading to more energy throughout the body during the day. Additionally, Aspartic Acid transports minerals throughout the body that help synthesize RNA and DNA in the cells and bolsters the immune system by increasing production of disease fighting antibodies immunoglobulins and antibodies.

Aspartic acid also functions as a powerful neurotransmitter that helps keep the mind sharp. Increased concentrations of NADH in the brain boost production of neurotransmitters, which enhance memory, focus, and cognition. Lastly, aspartic acid removes excess toxins from the cells, like ammonia, which can have very damaging effects to the brain and nervous system if they continuously build up.

Benefits of L-Aspartic Acid

  • Supports memory formation

  • Provides energy for cells

  • Vital for gluconeogenesis

  • Boosts cognition

  • Increased stamina

  • Glycogen sparing


Typical doses of L-Aspartic Acid range from 500mg-1500mg each day. Doses are usually split into 1 - 3 administrations and best consumed at least 30 minutes before a meal.
