D-Aspartic Acid: Can It Increase Testosterone Levels?
D-Aspartic Acid and Testosterone Levels
In this article, I am going to show you how D-aspartic acid can boost and increase low testosterone levels.
Have you tried different supplements and injections for boosting testosterone levels without getting any results? Well, now it’s time for a change.
D-aspartic acid is an acidic amino acid which occurs inside the body, mainly in the testicles. It is not an essential amino acid but is an alternate form of L-Aspartate which is one of the essential amino acids.
D-aspartic acid is often used in the bodybuilding community as a way of increasing both LH levels and testosterone.
Well, now you might be quite intrigued to know more about it. If you want to know more, keep on reading.
What is D-Aspartic Acid?
DAA is a form of aspartic acid which is one of the 23 amino acids, which serve as building blocks for your bodies proteins.
It’s a non-essential amino acid which means that the body can synthesize it and humans don’t have to consume it in order to maintain adequate levels.
D-aspartic acid appeared on the marketplace in the 1990s and is often used by bodybuilders when bulking up and increasing muscle gains.
There are multiple uses of D-aspartic acid, including:
Decreasing risks for developing cardiovascular disorders
Increasing testosterone levels
Enhancing the calcium levels in the body
Helping gain lean muscle and decrease fat storage
Can D-Aspartic Acid Increase Testosterone Production?
D-Aspartic acid is present inside the testicular Leydig cells. It is believed that it receives signals from the pituitary glands and passes them to the Leydig cells where it converts cholesterol into testosterone.
So basically D-aspartic acid increases testosterone levels by improving the process of information between the hormones and cells in the brain and gonads.
Although there has not been a massive amount of studies done on humans, the studies that have been done show that D-aspartic acid can be beneficial in boosting testosterone in men with low T levels. For men with adequate levels of testosterone, the studies have not shown these benefits.
The supplement can also have anti-aging benefits because the D-aspartic acid levels decline naturally as we age.
Studies on D-Aspartic Acid Being a Testosterone Booster
Here are some studies which show the benefits of D-aspartic acid for boosting low testosterone levels.
1)The first study was done to find out whether D-aspartic acid modifies the release of hypothalamic and posterior pituitary factors and whether its effects are because of nitric oxide.
The study showed that D-aspartate stimulated the luteinizing hormone and GABA release through the interaction with NDMA receptors. It increased nitric oxide levels and the effect on GABA was blunted when nitric oxide was initiated.
Seeing these results, the researchers concluded that D-aspartic positively increased luteinizing hormone and growth hormone levels.
2) After this came the first human study in which the researchers chose 43 subjects. 23 of these subjects were given D-aspartate for 12 days and the other group was kept in placebo.
When 6 days were passed, it was seen that in the D-aspartate group the testosterone levels increased by 12%. And after a total of 12 days, it was seen that the levels increased by 42%.
Although the study lasted for only 12 days, the researchers noted that the testosterone levels in the D-aspartic acid group was 22% higher and the amino acid was still quite active in the tissues after discontinuation of the study.
3)Another study was done to investigate the supplementation of sodium aspartate and its involvement in sperm motility. The subjects of the study were 30 patients suffering from oligo-asthenozoospermia (low sperm motility), who were given D-aspartate for 90 days.
The results of the study showed that supplementing D-aspartate significantly increased the concentration of spermatozoa. The patients showed a rapid increase in the progressive spermatozoa motility.
The researchers stated in the conclusion of the study that the treatment of sub-fertile patients with D-aspartic acid increased the production of spermatozoa.
D-Aspartic Acid Side Effects
Research has proven the benefits of D-Aspartic acid for muscle building and for helping men with low testosterone. But are there any side effects?
The truth is that when D-aspartic acid is consumed in doses less than 4 grams per day there are very few reported side effects.
However, although uncommon there are some side effects mentioned below.
Increased aggression.
Acne
Elevated Kidney Levels
Larger Appetite
Elevated Liver Enzymes
Hair Growth
Adverse Cholesterol Effects
The side effects mentioned above are rarely seen in low doses. There was even a study done that had subjects take 2,600 mg of D-aspartic acid for 90 days, and throughout the study, the researchers measured the participant’s electrolytes, creatinine, glucose, blood cells, and enzymes regularly and they found no problems.
Conclusion
I hope this article has given you some information about how D-aspartic acid can boost and increase low testosterone levels.
From all the research that has been done on D-aspartic acid what we can conclude is that D-Aspartic acid can be beneficial for men who have low testosterone levels. However, men with adequate levels of testosterone will not see the same results.
If you decide to try D-aspartic acid make sure not to consume high doses and make sure to choose a good quality D-aspartic.
