What is D-Aspartic Acid?

The million dollar question. Turns out, D-aspartic acid is one of the many amino acids that aid in protein synthesis.

It’s a non-essential amino acid, which means your body can produce a functional amount of D-aspartic acid naturally.

D-aspartic acid is actually only half of the aspartic acid equation. The other half is what’s known as L-aspartic acid. These two forms have different benefits from one another; we’ll focus on D.

This amino acid participates in endogenous (inside the body) testosterone production.

The process is governed by the HPTA – Hypothalamus-Pituitary-Testes Axis. It is within these three glands where D-aspartic acid is created through enzymes breaking down proteins.

Specifically, D-aspartic acid – also called D-aspartate or DAA – releases hormones in the brain or testicals, telling the body to produce more testosterone naturally.

This would be why D-aspartic acid is found in various testosterone boosters and other supplements like that.

Is D-Aspartic Acid a Steroid?

A steroid is a biologically active organic compound constructed a certain way. Testosterone is one of the major steroids made within the body.

The steroidogenic acute regulatory (StAR) protein is present in the HPTA and mediates exactly how much testosterone is produced at any given time.

What D-aspartic acid does is stimulate this StAR protein, which increases the amount of StAR. Therefore, the cholesterol allowed into the mitochondria is increased too.

This is where steroids like testosterone are produced.

So the technical answer is NO, D-aspartic acid is not a steroid.

It is a non-essential amino acid that upregulates a protein, which in turn enhances the production of a hormone your body is already making.

You don’t produce a ton of DAA in your body naturally, making supplementation a solid solution for extra testosterone.

D-Aspartic Acid Benefits?

Now that you know a little of the science behind this supplement, you could probably guess what some of the benefits of DAA are.

Here’s the gist:

  • Muscle Building is Enhanced: Weird – muscle website, muscle supplement. With an increase in testosterone, you improve muscle protein synthesis, which results in lean muscle mass. Plus, it limits cortisol, the stress chemical that adds abdominal fat and breaks down muscle tissue.
  • Sperm Count is Elevated: Male fertility is greatly affected by DAA. Sperm count and motility is increased, which creates an enhanced libido and higher chance of pregnancy with your partner.
  • Energy Levels Increase: Another benefit to having additional testosterone, you get better sleep. This means optimal recovery and extra energy during the day. Also, the higher testosterone translates to a higher red blood cell concentration, which is more oxygen delivered to the muscles.
  • Psych Levels of Compounds are Heightened: More testosterone is not the only thing D-aspartic acid does. It also increases growth hormone (HGH) and insulin-like growth factor 1 (IGF-1). These all have positive impacts on many areas of human production, such as athletic performance and sexual ability.
  • Higher Production of Thyroid Hormone: If DAA is oxidized in the thyroid gland, thyroid hormone production increases. This affects your metabolic rate, jacking it up to higher levels. You burn more calories, you get leaner, you win.

Of course, these benefits will only occur if you supplement D-aspartic acid properly, with correct doses, frequency, and cycling (more on these later).

D-Aspartic Acid Results

However, while there are biological processes at work here, it’s not to say that this works 100% of the time.

Research and studies have given mixed results for D-aspartic acid. Here are the findings…

Will taking DAA help you lift more? Actually, there isn’t much research into DAA and strength training.

Any claim that D-aspartic acid improves your lifts will be anecdotal at this point, which means it might not give you the same results.

Will it help with weight gain? Again, no scientific evidence. Biologically, DAA should alter your body composition in some way, but the lack of research makes it more like a wild guess.

Does DAA enhance male fertility? There’s some research that backs this claim up. However, it’s weak and could vary from person to person.

Is DAA better than other testosterone boosters, like DHEA or Tribulus Terrestris? Due to the lack of studies, it’s tough to say D-aspartic acid is inherently “better” than other, highly-tested supplements.

When it comes to asking your doctor or other medical professionals, it’s doubtful they’ll recommend DAA over DHEA, Tribulus, or any stronger-studied supplements.

While this is the case, there are multiple anecdotal pieces claiming the effectiveness of DAA.

The only way to know for sure is to test it out for yourself. By tweaking the dosage and cycling based on your goals, you’ll be able to see whether you’ll get results fairly quick.

It’s best to avoid taking DAA at all if you aren’t male, over the age of 21, or dealing with excess levels of estrogen.

However, if you’re a guy, over 21, have low libido, or are looking for a natural route to endogenous testosterone production for anabolic purposes, DAA just might be the key.

D-Aspartic Acid Dosage?

The overall range of dosage is 3-20 grams. When you start out, do so with the low side of this range (i.e. 3 grams). Never exceed 20 grams, as this is too high for most individuals.

The optimal range for DAA is actually 5-10 grams daily.

When Should You Take It?

Split your dose up between morning and evening, especially if you’re taking more than 5 grams. Or, if you want to see how your lifts are affected, take half before your workout and half before you head to bed.

How Long Does it Take to Work?

If your diet and workout regimen are both on-point, you should expect drastic, significant results in 1-2 weeks.

This is a fast-working supplement; because you see such changes so quickly, it is ideal to cycle on and off D-aspartic acid. (We will go over cycling in a few sections.)

Capsules vs. Powder

D-aspartic acid comes in both powder and pill form. Which one is better for you though?

Honestly, the biggest differentiator is going to be preference. Would you rather take DAA as a capsule or in water as a powder?

Other than that, there are a few comparisons to draw here:

Cost: Powders usually cost less per serving than pills do.
Travel: Pills are easier to tote around in a gym bag than a tub of powder.
Taste: The top reason why some people prefer pills; how good does your DAA powder taste?
Doses per bottle: Companies pack more pills – and more doses – in a bottle than powder due to more space.

Based on price, convenience, taste, and amount, you can get a decent idea of which type of D-aspartic acid you should use as your go-to supplement.

Do You Need to Cycle D-Aspartic Acid?

In short, yes. The best cycle is to be on DAA for 2-3 weeks, followed by a 1-2 week hiatus from the supplement, then repeating.

During the “on” portion of the cycle, split up your dosage during the day. Follow your nutrition and training routines to the best of your ability.

During the “off” period, make sure you take vitamins to reestablish your body’s homeostasis.

This cycle is vital to bodybuilding performance and overall health because this keeps the supplement potent when ingested.

Also, it helps you avoid altering your body’s chemistry, such as shutting down natural anabolic processes that create testosterone. Unsuppress your body’s systems and maintain tolerance for DAA by cycling quickly and often.

D-Aspartic Acid Side Effects

Since DAA is a non-essential amino acid that’s already made in the body, you aren’t harming your body by pumping it full of pharmaceutical compounds.

However, even though they aren’t anabolic steroids or prohormones, it raises testosterone and other hormones.

Therefore, there are potential side effects, especially if you cycle DAA too long or take too much in a daily dose.

Here are the common side effects:

  • Increased dihydrotestosterone levels; this could increase acne and result in hair loss.
  • Additional estrogen levels; this translates to bloating, prostate issues, inhibited libido, and possibly gynecomastia (note: this won’t happen if you cycle DAA correctly).
  • Adversely affects the kidneys and liver; because of extra DAA, organs that handle the production of testosterone work overtime, which can cause inflammation, damage, or fatigue.
  • Unhealthy cholesterol changes; this is a result from negatively-affected kidneys and liver. Obviously, high cholesterol has its own slew of problems, including risk for heart disease.

Like we previously mentioned, if you cycle properly, the majority of these side effects won’t have a chance of happening.

Though the first one – hair loss and acne – could still occur. Monitor body changes when on a cycle of DAA and see whether you need to adjust the dose, cycle length, or not use it at all.
