DAA (d-aspartic acid) is the dextrorotatory form of aspartic acid, one of the 20 amino acids that make up proteins. This supplement enhances the release of some hormones that affect the testosterone levels (luteinizing hormone). Along with this effect, sperm show an improved mobility, hence this supplement is used in cases of infertility.
The interest in this compound lies in its basic action, which is the release of certain hormones that influence testosterone levels (luteinizing hormone).
An improvement in sperm mobility was observed alongside this effect, hence the use of this amino acid supplementation in cases of infertility.
Aspartic acid: the non-essential amino acid that stimulates physical and intellectual performance
What is aspartic acid?
Aspartic acid is a non-essential amino acid that can be generated by the body from the nutrients ingested in the food.
This is the basic characteristic of this type of amino acid, which is essential for health and many bodily functions.
Aspartic acid is a key element in our asparagine synapses and neurotransmitters.
Some studies now show that it exercises a specialised neurotransmitter function in the parts of the nervous system involved with the synthesis of hormones, such as luteinizing hormone (LH) and growth hormone (GH) from the pituitary gland.
It is important to have information about the multiple health benefits of this nutrient, since it increases physical and mental energy, stamina and stimulates muscle growth.
What determines the level of aspartic acid?
Given that these non-essential amino acids can be generated by the body itself, the basic sources are dietary.
Who has a greater need for aspartic acid?
The human body has the capacity to produce these amino acids if you receive enough protein through diet.
However, on certain occasions there may be a greater need for this nutrient, especially in the following cases:
- Malnutrition or extreme diets: in the most severe cases of anorexia and bulimia an aspartic acid deficiency may be present. The same applies with extreme or poorly balanced diets in which few proteins are consumed.
- Stressful situations: In stressful situations, sporting competitions, and with lack of sleep and emotional or mental tension the body's need for these amino acids increases.
- Diseases: this amino acid is not completely assimilated in cases of metabolic disorders and chronic inflammatory diseases of the intestine, which cause a deficiency.
Is an excess of aspartic acid possible?
Although aspartic acid is present in foods that contain protein and even in other types of food, the latest clinical studies conclude that a great excess of this substance cannot be produced, since the body consumes it directly or uses it as a raw material to create other amino acids. It is also excreted easily.
However, when taking it in large quantities in dietary supplement form there may be an excessive increase in the short term. This especially occurs in the case of sportsmen and athletes who take these amino acids to improve their strength and performance.
What are the symptoms of aspartic acid deficiency?
It is very difficult to diagnose and isolate a deficiency of this nutrient, so it is not easy to detect all the symptoms, but the following are among the more easily identifiable:
- Decreased physical performance: this non-essential amino acid deficiency produces fatigue, chronic fatigue, muscle weakness as well as low strength and endurance
- Decreased cognitive performance: aspartic acid acts as a neurotransmitter. Cognitive and intellectual performance depends, in large part on this amino acid. When there is a lack of this amino acid a decrease in concentration and memory, lack of coordination and slow reaction time can all occur.
- A lack of aspartic acid, can also indirectly decrease libido and cause many health problems, such as liver or kidney dysfunction and weakness of the immune system. Decreased testosterone production and hormone fluctuations may also take place.
What are the symptoms of an aspartic acid overdose?
Although overdoes are very rare, they can occur at times, causing mild discomforts such as nausea, vomiting and diarrhea.
Information about sources of aspartic acid
This acid is present in all foods that contain protein. Among its main sources we can highlight:
- Meats (beef, pork, poultry), fish and seafood
- Legumes and vegetables: asparagus, soybeans, fava beans, peas, tomatoes, peppers and carrots.
- Nuts, seeds and dried fruit: peanuts, cashews, poppy, linseed, sesame, pumpkin, sunflower and mustard seeds.
- Eggs, cheese and dairy products.
- Cereals: wheat, oats, quinoa and barley.
- Spices: parsley, mint and oregano.
Properties and benefits of Aspartic Acid
- Increases physical performance and endurance and also increases muscle mass
- Regulates the hormonal system and increases the production of testosterone
- Increases the energy supply
- Improves resistance to stress, physical and mental
- It has revitalizing effects
- Stimulates muscle growth and reduces the loss of muscle mass
- Improves intellectual performance and stimulates concentration, memory and reflex speed
- Improves problems such as depression, anxiety or stress.
- Stimulates the healthy functioning of the liver and kidneys and purifies the blood (helps to eliminate toxins from the blood).
- Strengthens the immune system and protects general health
- It has detoxifying properties, thanks to its ability to eliminate ammonia from the body.
- Beneficial for avoiding fatigue or chronic fatigue syndrome.
- Has a remineralising effect, since it promotes the assimilation of calcium, potassium, magnesium and zinc. That's why aspartic acid is indirectly involved in proper bone mineralization.
- Because of its ability to increase potassium assimilation, it helps reduce fluid retention in the body.
- Promotes the health of veins and arteries, sinces it encourages elasticity and resistance, helping to avoid cardiovascular problems such as atherosclerosis.
Aspartic acid side effects
There are no known specific side effects of aspartic acid. The latest clinical studies conducted on the matter concluded that the possible side effects are similar to those of a general increase in amino acid levels in the blood.
Clinical studies have established that the possible side effects of an overdose of aspartic acid are limited only to slight discomfort in the digestive tract.
Benefits of aspartic acid dietary supplements
Aspartic acid increases energy and physical performance and reduces exhaustion and chronic fatigue. Another of its benefits is the increased production of testosterone. If you wish to undergo a prolonged intake of these dietary supplements we recommend consulting a doctor.
In any case, one must take care not to excede the recommended daily dosage. The consumption dietary suplements can also be combined with other food products that contain this amino acid, such as legumes, dried fruit, seafood, seaweed, cheese and lean meats.
Cooking resistance of products containing aspartic acid
Knowing the cooking resistance of products that contain aspartic acid is important in order to make the most of its benefits. The information we have on these amino acids is that they are very heat resistant and can be cooked in various ways, retaining all the vitamins and health properties.
Still, whenever possible it is recommendable to consume this kind of food fresh and raw, as this will maximise its benefits in a healthy and balanced diet.
How to take aspartic acid
The most provenly effective dose for aspartic acid is 2-3 g daily.
The way to take it is:
- 3g per day for 12 days, with a break of 7 days
The best time to take aspartic acid would is before training, or during rest days when one gets up with an empty stomach or before bedtime.
