Aspartic acid is a non-essential amino acid and is found in abundance in plant proteins, especially in sprouting seeds but can be manufactured in the body from oxaloacetic acid and was first isolated in 1868 from legumin in plant seed. Aspartic acid, as well as glutamic acid, is the only amino acid that has a negatively charged carboxylate group on the side chain.
L-Aspartic Acid plays a vital role in energy production and is a major excitatory neurotransmitter. It is one of the components necessary to move high energy NADH molecules from the main body of a cell to its mitochondria, or primary energy-production areas. Once there, the NADH is used to generate ATP, the energy fuel that powers all the cells' activities.
It is of paramount importance in the metabolism during construction of other amino acids and biochemicals in the citric acid cycle. Among the biochemicals that are synthesized from aspartic acid are asparagine, arginine, lysine, methionine, threonine, isoleucine, and several nucleotides.
Because aspartic acid increases stamina, it is good for fatigue. Chronic fatigue may result from low levels of aspartic acid, because this leads to lowered cellular energy.
It is needed for neural health and is beneficial for neural and brain disorders.
It is good for athletes, and helps to protect the liver by aiding in the removal of excess ammonia. Aspartic acid combines with other amino acids to form molecules that absorb toxins and remove them from the bloodstream.
It aids cell function and the function of RNA and DNA, which are the carriers of genetic information. It enhances the production of immunoglobulins and antibodies (immune system proteins).
Sources
Plant protein especially that found in sprouting seeds, contains an abundance of aspartic acid. It is also found in dairy products, beef, poultry, beans, brewer's yeast, brown rice, nuts, seafood, seeds, soy, sugar beet molasses, whey, whole grains, young sugar cane.
Molecular Description
Aspartic acid is one of two amino acids (the other is glutamic acid) that has a negatively charged carboxylate group on the side chain. This gives aspartic acid an overall negative charge at physiological hydrogen ion concentrations (approximately pH 7.3). Although aspartic acid is considered a non-essential amino acid, it plays a paramount role in metabolism during construction of other amino acids and biochemicals in the citric acid cycle. Among the biochemicals that are synthesized from aspartic acid are asparagine, arginine, lysine, methionine, threonine, isoleucine, and several nucleotides.
Health Benefits
Aspartic acid has been indicated for use to treat chronic fatigue (alone or with arginine), depression, heart failure, infertility, irregular heartbeat, loss of energy, and toxemia.
Aspartic Acid Deficiency
Symptoms may include fatigue and depression.
Aspartic Acid Dosage
1/4 to 1/2 teaspoon daily L-apartic acid powder between meals or as recommended by your health care provider. 1/2 teaspoon of supplemental powder contains 1.9 g of L-aspartic acid. A good source of aspartic acid is Source Naturals.
Supplement Forms

Liquid
L-aspartic acid is also known as: Aminosuccinic acid, Asp, asparagic acid, asparaginic acid, Aspartate, COOHCH2CH(NH2)COOH, L-Aspartate.
Cautions
If you are pregnant or breastfeeding, consult your health care provider or midwife before using this product. Keep out of reach of children.
Toxicity of aspartic acid may cause brain damage.
ASPARTIC ACID SUPPLEMENT PRODUCTS
