D-ASPARTIC ACID SUPPLEMENTS
D-aspartic acid, or D-aspartate, is an amino acid that is found in the human body. It is considered a non-essential amino acid because the body is able to produce it itself, so it is not necessary to get enough of it in your diet. However, many foods that we eat every day, such as meats, eggs, and dairy, contain D-aspartic acid.
Aspartic acid comes in two forms: D and L. L-aspartic acid, also known as L-aspartate, is used in the body to build up proteins and create DNA. D-aspartic acid works to stimulate and control hormone release. It performs the majority of its functions in the endocrine system, which is made up of the glands in the body responsible for producing hormones.
One of the main outcomes of taking D-aspartic acid is testosterone increase, so this product is most commonly taken by men. There are many other benefits as well that come about from stimulating the central nervous system. These benefits can be both physical and mental. Here is everything you need to know about D-aspartic acid and how it works.
How D-Aspartic Acid Works
D-aspartic acid is found in both humans and animals, and it plays a similar role in both. D-aspartic acid is mainly found and stored in the pituitary gland and in the testicles. This amino acid is known to stimulate the release of luteinizing hormone and follicle-stimulating hormone. These play a role in fertility. In men, they increase sperm production and control the function of the testes. D-aspartic acid also increases growth hormone release, which stimulates muscle, bone, and tissue growth.
It also plays a major role in testosterone production and release. In the testicles, the amount of testosterone that is produced is limited based on the amount of other hormones present. By increasing the amount of D-aspartic acid in the body, this limited reaction can be sped up, causing an increase in testosterone production.
The Health Benefits of D-Aspartic Acid
D-aspartic acid can control a number of hormones in the body that can benefit you in many ways. The benefits that can be seen are both physical and mental.
D-aspartic acid supplements are best known for their ability to increase testosterone levels. One study looked at 23 men who were between the ages of 27 and 37. They took supplements for 12 days, and 20 of the men had increased testosterone levels. The average increase for the group was 42 percent.
Even after they stopped taking the supplement, their testosterone levels were still 22 percent higher after three days. Another study lasted for three months. The participants in this study noted between a 30 and 60 percent increase in testosterone levels.
There have also been other studies that have shown that D-aspartic acid is not effective at increasing testosterone. But many of these studies chose participants that lived a physically active lifestyle. Because of this data, it is most likely true that D-aspartic acid supplements work better for people who are not very active or have low testosterone levels to begin with. For these people, these supplements can be very effective and beneficial.
D-aspartic acid supplements have also been shown to improve fertility. As mentioned before, this amino acid regulates the levels of many hormones. Two of these are luteinizing hormone and follicle-stimulating hormone. These hormones play a role in sperm production and how well the testicles can function. Taking D-aspartic acid can also increase sperm motility, which is its ability to move.
One study of 60 men who were experiencing fertility problems took D-aspartic acid supplements for three months. After this period of time, total sperm production increased dramatically, as did motility. Other studies have shown that the partners of men who took D-aspartic acid supplements had a higher chance to become pregnant.
More research has to be done, but there is also a decent chance that D-aspartic acid could be beneficial for women to take. It may have a positive effect on ovulation and play a role in their fertility as well.
HIGHER ENERGY LEVELS
D-aspartic acid supplements can also lead to increased overall energy, both in the gym and throughout daily life. This benefit is mainly seen from increased testosterone production. Testosterone is responsible for increasing energy production in the body. This is one of the reasons this type of supplement is taken by athletes and weight lifters.
A past study reported that almost a quarter of men who had low levels of testosterone suffered from fatigue. Having higher energy levels can increase your endurance and boost performance during workouts and competitions.
MUSCLE AND STRENGTH INCREASES
Testosterone is key for muscle and strength increases in the gym. Taking D-aspartic acid supplements can raise levels of this important hormone, which can lead to better workout performance. Testosterone is needed to stimulate the production of new proteins, which causes new muscle tissue to grow and develop. This can make your workouts in the gym more effective and optimize their benefits.
Taking D-aspartic acid supplements can also lower your body’s cortisol production. Cortisol is known as the stress hormone. When levels of this hormone are too high, it can result in high blood sugar, extra fat production, and a breakdown of muscle tissue. Keeping cortisol levels low can help make sure that your body doesn’t add any unneeded fat and keeps its muscle tissues intact.
Another benefit of increased testosterone is better sleep quality and quantity. Low levels of testosterone have been tied to sleep disorders, including sleep apnea and insomnia. Having higher levels of testosterone helps increase the amount of sleep you are getting each night.
Getting more sleep can boost your energy levels for the next day and strengthen your body and immune system to keep you healthier. If you are an athlete, getting better sleep each night can also improve your recovery from workouts, getting you back in the gym quicker.
Testosterone also plays a role in your red blood cell production. Red blood cells are responsible for transporting oxygen to tissues throughout the body. Having higher levels of testosterone increases how many red blood cells you make and raises their concentration in the blood.
A higher concentration of red blood cells means that you can transport more oxygen at one time to keep your muscles energized and strong. This can help your body perform better during workouts and recover better after them as well.
BETTER HEART HEALTH
Heart disease is the leading cause of death for both men and women in the U.S. Keeping your heart healthy is critical for a long and happy life. Like we stated, taking D-aspartic acid helps increase your oxygen concentration in the blood. Getting your heart enough oxygen is critical to keep it working its best.
D-aspartic acid supplements can also stimulate testosterone and widen the blood vessels. This allows more red blood cells and oxygen to reach the heart and muscles in the body. This ensures that the heart has enough energy to function effectively.
IMPROVED MENTAL HEALTH
Not only does D-aspartic acid have a number of physical benefits, it has mental ones as well. Mental health issues–such as depression–are serious, and having low testosterone can contribute to these feelings. Low testosterone levels can also cause irritability and general tiredness. Taking D-aspartic acid supplements is a great way to combat this and raise your mood levels.
This supplement also may be able to help with memory and concentration problems. Increasing and rebalancing your hormone levels can improve these issues, and they can help improve motivation and confidence as well.
What To Look For When Buying D-Aspartic Acid Supplements
Many D-aspartic acid supplements are named just that, and most of them list D-aspartic acid as the only ingredient. Since this is often advertised as a testosterone boosting supplement, some supplements that include D-aspartic acid may also contain other ingredients to increase testosterone. Other ingredients can include horny goat weed, cholecalciferol, and others.
Supplements may also include various vitamins and minerals. In fact, vitamin D has been shown to have many positive benefits related to testosterone levels. It is important to be sure that you recognize the ingredients in your supplements. If there are ingredients that you are not familiar with, you should research them to be sure you are putting the proper ingredients in your body.
The Proper Dosing of D-Aspartic Acid Supplements
The proper dose of a D-aspartic acid supplement largely depends on the specific ingredients included. In most cases, following the instructions written on the product is probably a safe way to go. Many studies have been done on D-aspartic acid supplements specifically.
In general, a daily dose of around three grams per day produces optimal benefits. But this is mainly because that is the most commonly used dose in studies. Most studies used doses that ranged from 2.5 to three grams per day, but two studies used doses up to six grams per day. The higher doses did not produce promising results, so it is important to make sure you are not taking too much of this supplement.
It is also best to cycle your supplementation. To do this, you should take the daily dose of your supplement for between four and 12 weeks. After this time period, you should stop taking any D-aspartic acid for between two and four weeks. This will allow it to clear out of your system so that you do not build up a tolerance. This way, when you begin taking it again, you will be able to get the most out of your supplement.
Possible Side Effects of D-Aspartic Acid
In general, taking D-aspartic acid supplements is very safe and is associated with very few negative side effects. A few of the minor side effects include acne, headaches, and mood swings. This makes taking this supplement relatively risk-free.
There are a couple of potential side effects that are more severe, but they are rarely seen. One of these side effects is high levels of liver enzymes. If these enzymes become elevated, it can cause inflammation and damage your liver cells and affect its function.
Your kidney markers could also be elevated. Kidneys perform many functions, including filtering waste, regulating blood pressure, and regulating acid levels. Certain markers, like urea, uric acid, and creatinine, are used to gauge how well your kidneys are working. These can become elevated, meaning that your kidneys are not working effectively. Due to kidney and liver problems, you also may see your cholesterol levels rise.
