Foods That Contain D Aspartic Acid

Dietary protein is vital for all of the cells in your body to operate correctly. When you eat food that is rich in proteins, your digestive system converts them into amino acids. Amino acids are the core building blocks of proteins. It powers many metabolic reactions and is efficient in creating new proteins. With that in mind, here’s a detailed article on “What Foods Contain D Aspartic Acid?”

D Aspartic Acid

It’s an amino acid that feeds enzyme processes for various purposes. Among other things, it includes providing energy for the cells in your body.

Because the cells can produce the amino acid, you do not require it in your diet. At the same time, various foods can help you get more of it.

The Role of D Aspartic Acid

The pituitary gland, testes, is responsible for the production of D Aspartic acid. It plays a role in releasing, controlling, and synthesizing the luteinizing and testosterone hormone.

Aspartic acid plays a very vital role in the making of four essential amino acids. These are isoleucine, lysine, methionine, and threonine.

  • Isoleucine is responsible for regulating energy.
  • Lysine plays a vital role in muscle turnover and its growth.
  • Methionine is essential for metabolism.
  • Threonine is important for the immunological system, central nervous system, cardiovascular system.

What Foods Contain D Aspartic Acid?


Different types of critical micronutrients, D-aspartic acid including, may be found in almost all varieties of fish. Salmon has a lot of amino acids and Omega 3 fatty acids.



Dairy Products and Eggs


Eggs are rich in sources of protein. It includes all of the necessary amino acids that the body requires for healthy development.

According to research, the human body is able to absorb the amino acids found in eggs at a fast rate. That is in comparison to those found in soy or casein that the body utilizes at a much slower pace.




  • Cottage cheese includes high amounts of many types of D Aspartic Acid. That includes tryptophan and threonine, among many others. It’s able to offer around 25% of the daily protein intake needs in a 100gm serving.
  • A cup of mozzarella contains around 2.5gms D Aspartic acid.
  • 1.3gms of the amino acid is present in every half of Parmesan cheese.
  • Swiss cheese, cheddar, and provolone also contain similar quantities of Aspartic Acid.

Other than eggs and cheese, dairy food items such as butter, cream, and yogurt are also efficient sources.



Meat and Poultry 


Poultry contains a lot of tryptophan, an amino acid used by the human body. It keeps the skin health, nerves, and digestion in check.

Tryptophan is present in huge quantities in Turkey (dark and white meat). It contains about 2.8gms of it.

The acid plays a very important factor in the making of niacin, also known as Vitamin B.

Vitamin B is crucial for healthy nerve functions, healthy skin, and digestion. The amino acid aids in the production of serotonin.

Serotonin is the hormone that influences mood and can lead to feelings of relaxation and joy.

3.7gms of the amino acid is present in a cup of finely chopped, roasted chicken (white meat).




Meats are also excellent providers of D-aspartic acid. It includes food sources such as pork spareribs, meat sausages, wild game, and so on. The reason is that they have high levels of protein.

In that regard, you get about 2.4gms of Alpha Aspartic acid with three ounces of beef roast. Also,4.5gms of the same is present in a beef fillet of average size.

Plant-Based D Aspartic Acid Sources


Quinoa is among the most nutrient-dense grains currently accessible. It includes the nine vital amino acids that the body requires.

Quinoa is not only a rich source of fiber but also contains vast quantities of lysine content than rice or wheat. That makes Quinoa a superior supplier of the said amino acid.




Mushroom houses seventeen amino acids in total. It includes all of the important ones that the body needs for healthy functioning.

According to one research, a diet consisting of mushrooms and cereal can aid with lysine deficit.



Legumes and Beans

Legumes are another food source that contains rich amounts of protein. About 17-20% essential variety of protein is present in Beans and peas. Soybeans and lupin house around 38-45%.

Beans and Legumes: 

  • Edamame
  • Black beans
  • Peanuts
  • Lentils
  • Peas
  • Garbanzo beans
  • Cooked kidney beans
  • Soybeans
  • Chickpeas

The amino acid is available as powders, tablets, and fluids. It can be found in food supplements, proteins, and multivitamins.

Effects of the Aspartic Acid: Research Results

Increasing fertility in males

A research study carried out a sample size of thirty men with low sperm count. It also included thirty men with low sperm motility.

Each group received a daily dose of D Aspartic acid for a total of ninety days. It led to a massive rise in both the number and motility of sperm generated by men.

Thus, the research indicated that Aspartic Acid could improve male fertility.

The benefits of aspartic acid for female fertility are less well-studied. That’s due to the role of Aspartic Acid in the maintenance of the male hormone testosterone.

Most of the studies investigating the association between fertility and Aspartic Acid focuses on male fertility.

Building muscle strength and mass

D-aspartic acid is a popular element in products geared towards people who train and work out. It aids people who wish to gain muscle strength and build mass. It’s because of the said amino acid’s involvement in the control of the male hormone.

There’s no evidence to support the study on the effects of Aspartic Acid on muscle mass. That is, whether it boosts strength, muscular growth, or enhances the levels of testosterone in male weight trainers.

Popular belief states that males who received D Aspartic Acid showed positive gains in muscle strength and testosterone.

At the same time, there are no definitive results from studies on the impact of Aspartic Acid. Thus, a study to support the widely reported advantage is widely absent.
