D Aspartic Acid and Testosterone – Study Analysis | Side Effects

08 Sep D Aspartic Acid and Testosterone – Study Analysis | Side Effects

D-Aspartic acid and testosterone have been linked so far, and a lot of research clearly states their correlation.

However, most men still are not sure whether the amino acid really affects men’s hormonal state. So, does D aspartic acid increase testosterone or is it just a fuss?

While considering the ingredients label of several testosterone-boosting pills, D-aspartic acid is one that’s common. However, a detailed analysis of the components itself is important to find out what makes them combine the amino acids in the formula.

D-Aspartic acid, or DAA, is an amino acid that commonly inhibits the biosynthesis of proteins. The naturally occurring amino acid is one of two D-amino acids commonly found in mammals. These two are opposites to each other, namely, D-aspartic acid and L-aspartic acid.

Furthermore, the Aspartic acid comprises a (CH2COOH) acidic side chain that eventually reacts with the other amino acids as well as the enzymes of the body.

This reaction ultimately results in fluctuations of hormones including testosterone.

But does D Aspartic Acid actually increase testosterone levels? Follow up here with the blog to acknowledge the facts about D-Aspartic and Testosterone.

D- Aspartic Acid Effects on Testosterone

Regular research claims that the most common reason for supplementing with D-aspartic acid is the instant boost of testosterone. Studies on the D aspartic acid effects on testosterone have yielded mixed results.

Unlike most amino acids, DAA has grabbed attention for its effects on testosterone production. The popular amino acid regulates the synthesis and secretion of hormones that are intentionally combined in the production of testosterone.

A study published in the Journal, Reproductive Biology and Endocrinology, states that supplementing DAA optimizes testosterone levels, and 87% of participants have experienced increased testosterone levels just after 12 days.

The research also mentioned the positive effect of this amino acid on the release of LH and testosterone serums. Further, we’ll discuss some additional D aspartic acid testosterone studies in the next segment.

D-Aspartic and Testosterone – Scientific Evidence

The scientific approach certainly gives a clear assumption about the component itself. That’s why we’ve enlisted some helpful studies that may give a clear overview of how does D aspartic acid increases testosterone.

Study 1 – D-Aspartic Acid Releases Free Testosterone

A group of 23 men has been given an optimum dose of D-aspartate (DADAVIT®) and another group of 20 men is kept on a placebo. After 12 days, tissues were incubated with D-aspartate, and a concentration (synthesis) of testosterone and cAMP in the Leydig cells was determined.

Further, a study, published in the Journal of Reproductive Biology and Endocrinology, was performed by using human subjects where two groups of healthy male volunteers aged between 27 and 37 years. Both groups are at the IVF (in vitro fertilization) Unit, Hospital “S. Luca”, Vallo della Lucania, Italy.

For 12 consecutive days, the first group consumed a solution of 10 ml of 2.0 M sodium D-aspartate (3.12 g/10 ml)  by mouth. The sodium D-aspartate solution has been given with vitamin B6, folic acid, and vitamin B12 diluted in water. Right after 12 days a significant increase in the testosterone levels is determined.

Study 2 – D-Aspartic Acid Regulates the Reproductive Cycle

A study performed on laboratory animals and published in the journal, Biomolecules, significantly assures that D-aspartic acid consumption leads to an increase in the testis just before birth and during sexual maturation.

Furthermore, in the same study, sodium D-Aspartic was supplemented with vitamins B6 and B12 for 12 consecutive days. After six days of the DAA administration, LH increased only 1.07-fold right after 12 days of treatment. As a result,  the LH levels increased significantly.

Study 3 – D – Aspartic Supports Spermatozoa Concentration

Since DAA has a great impact on the synthesis of testosterone and LH, a study published in Advances in Sexual Medicine has investigated the impact of supplementation of sodium D-aspartate on Spermatozoa Concentration.

A group of 30 patients affected with asthenozoospermia and oligo-asthenozoospermia are separately observed by supplementing with sodium D-aspartate.

After 90 days of consuming sodium D-aspartate in optimum dosage, a significant increase in the concentration and the motility of spermatozoa is examined.

Study 4 – Relation Between D Aspartic Acid and Hormonal Activity

Another research on the endogenous amino acid done by Life Sciences exhibits the role of DAA on testosterone synthesis in rats.

In the research, adult male rats were injected with injections of D-Asp. After 5 hours the amino acid accumulates in the pituitary and testis. Within 5 hours of injecting 12 and 4-fold over basal values have been observed.

Further, the luteinizing hormone, testosterone, and progesterone levels also increase in the blood by 1.6-fold, p < 0.05; 3.0-fold, p < 0.01 and 2.9-fold, p < 0.01, respectively.

Now after analyzing the scientific approach to how d aspartic acid increases testosterone, you just wanna know the way it works.

How Does D-Aspartic Work?

DAA influences testosterone production by triggering a chain reaction. The instant upsurge of a chain reaction of hormonal events in the hypothalamus-pituitary-gonad (HPG) axis results in elevated T levels in men.

A rough graph that expresses how D-aspartic acid works in encouraging testosterone production is:

• By regulating the mortality of sperm
• Stimulating the hypothalamus to release gonadotropin-releasing hormone (GnRH)
• Supports hormonal Activity and synthesis of Luteinizing Hormone (LH)
• Encourages the synthesis and secretion of follicle-stimulating hormone (FSH)
• Ultimately both FSH and LH altogether facilitate the elevated production of T in Leydig cells of the testes
• Furthermore, it also balances the reproductive cycle irrespective of age.

The promising studies also influence users that DAA supplementation intentionally increases the growth of testosterone in men.

But to consume too much of anything is poisonous, so having a complete idea or knowledge of dosage is essential.

D-Aspartic Acid Dosage for Testosterone

Studies assure that in physically inactive males, DAA supplementation actively enhances the production of testosterone. However, combining the natural compound in optimum dosage is equally important.

Doses of around 2.6 – 3 grams per day of DAA are effective as they significantly increase testosterone production in young and middle-aged men.

However, older men around 27 to 37 years who had a lower mean baseline testosterone value (4.5 ng/mL) can take 3 grams to have a significantly noted increased testosterone value by 50% to 6.4 ng/mL.

Higher doses of 6 grams per day notably decrease testosterone levels in the long run. So, try not to exceed the dosage to get better outcomes, it may worsen the result.

Other Testosterone Related Health Benefits of D-Aspartic Acid

Certainly, D aspartic acid does increase testosterone but in contrast to this, it also delivers some other testosterone-related benefits. These d aspartic acid benefits eventually impact male fertility and support overall health.

#1. Treats Erectile Dysfunction

Consuming d-aspartic acid before bed may help in treating conditions like erectile dysfunction due to low testosterone. Since low testosterone levels can be influenced by consuming the optimum amount of DAA, it’s considerable for erectile functions influenced by low T or sperm motility.

#2. Boost Male Fertility

D-aspartic acid has a positive effect on testosterone levels by working within the testes and the central brain region, co-facilitating both ends of the HPG axis.

This, in turn, boosts male fertility and the ability to produce more testosterone and eventually leads to better reproductive health.

#3. Reproductive Health

A healthy male with elevated testosterone levels considerably represents good reproductive health. Supplementing d-aspartic acid and l-arginine together intentionally enhances the low levels of testosterone. This eventually leads to better reproductive health with improved overall strength.

#4. Improves Overall Strength

Since D Aspartic acid does increase testosterone levels in men, it also plays a role in maintaining overall strength. However, there is no significant study regarding the same. But raising testosterone levels ultimately elevates the production of energy and delivers immense strength.

#5. Boosts Hormone Production and Release

Combining Testosterone booster d-aspartic acid capsules in the diet plays a significant role in the overall production and release of LH as well as Testosterone.

Daily consumption of 1500-3000 mg of D-aspartic acid stimulates the mechanism of the pituitary gland and pushes it to produce more luteinizing hormone and growth hormone, and both are linked to testosterone secretion.

#6. Support Sperm Health

As per the study published in Advances in Sexual Medicine, D-aspartic acid consumption for an optimum period of time has a substantial approach to sperm regulation. The study mentions that users supplemented with D-aspartate have improved the rate of pregnancies of their partners by 27 percent.

Till now, we’ve considered how D Aspartic acid supports testosterone and what are its effects on the hormone. But does it negatively affect testosterone too?

Are There Any Side Effects of D Aspartic Acid?

There is a limited source that indicates any negative impacts of D-aspartic acid consumption. But some people still question does d aspartic acid decreases testosterone, so the straight answer to this is a no. Maybe an overdose of DAA may cause irritability, headaches, and nervousness in men.

However, a few people actively involved in resistance training have reported that DAA consumption eventually leads to nervousness, rapid heart rate, and headache.

So, in order to eliminate any possible d aspartic acid side effects, stick to the recommended dosage.

Sources to Consume D Aspartic Acid

Most people with low testosterone or athletes who want an instant surge of testosterone need to combine natural foods that enhance T levels.

D-aspartic-rich foods eventually help in the significant boost of LH as well as testosterone. Some of the testosterone supplements with d aspartic acid include:

Meat Products Rich in D Aspartic Acid

However, apart from these, there are some popular testosterone-boosting supplements available in the market that have D-aspartic acid as a part of their components. One of the most popular in that list is Testogen which boasts 2352mg of DAA in its formula. So, if you have low testosterone, you can also check out Testogen reviews to see if the T-Booster fits your bill.

So yeah, here the discussion over the role of D-aspartic acid for testosterone increase comes to an end. Let’s summarize the overall blog.

Summary: Does D-Aspartic Acid Increase Testosterone Levels?

The most reliable answer to the query is a fair yes! D – Aspartic Acid does increase the production of Luteinizing hormone as well as testosterone.

However, combining other dietary foods with the supplement is also vital. The natural formula can be helpful for age-related testosterone decline, so if you’ve any other complications, consult medical help before including a new supplement in your diet.

Along with this, with time, more research will also deliver the overall effectiveness of the amino acid.

If the testosterone decline is due to other reasons instead of age, considering a medical professional is the first thing one should do.

If you are a male, there are actually many ways to take care of your hormonal health. You can try eating healthy and include testosterone-boosting foods in your meal plan or a workout to increase testosterone can also do wonders.
