When it comes to popular testosterone boosting ingredients, arguably one of the top dogs is DAA or D-Aspartic acid. But that popularity also comes with doubts and concerns regarding the supposed D-Aspartic acid side effects.
Since this amino acid has been widely used for several years already, gym rats and anyone interested in giving their own testosterone production an oomph has been wondering:
Is it safe and what are the potential unwanted reactions of using it?
Thankfully though I’ve got you covered because today’s post is entirely dedicated to DAA and any adverse effects that it might have.
What Exactly Is D-Aspartic Acid?
D-Aspartic acid is a naturally occurring, non-essential amino acid and it’s the enantiomer (mirror image of a molecule, in scientific language) of Aspartate.
It’s a non-essential amino acid because our bodies produce it on their own.
Besides, DAA can be found in a plethora of foods, most notably in:
Meat (beef, chicken, pork etc.)
Cheese (parmesan, mozzarella, Swiss cheese etc.)
Vegetables (oat bran, white rice, corn etc.)
And of course, if you fancy something that delivers sufficient amounts of DAA per serving in the form of capsules, then there are plenty of quality supplements out there.
As a matter of fact, many contemporary testosterone boosters contain D Aspartic acid, so if you want to take this amino acid in the form of a supplement, you have many options to choose from.
Does D-Aspartic Acid Have Any Side Effects?
Not really – no nasty side effects related to DAA supplementation have been documented.
Still, it’s worth noting that there aren’t any particular studies that are entirely concentrated on examining any potential adverse reactions that may result from taking D-Aspartic acid.
But the ones that focus on its luteinizing hormone and testosterone-enhancing capabilities report no side effects… none, zero.
In fact, one particular study from 2009 (1) observed the molecular mechanism of DAA and it’s related to the synthesis of testosterone and luteinizing hormone.
Researchers used both humans and animals (rats) as test subjects and they studied the effects that DAA has on the release of T and LH for 12 days.
There’s not a single word about ANY unwanted reactions or something even remotely dangerous associated with D-Aspartic acid supplements!
Are The Supposed D-Aspartic Acid Side Effects And Aspartic Acid Dangers Just Myths?
Yes, I believe that this is the case.
And before you jump all over me, don’t forget that pretty much any supplement can have side effects if you’re abusing and misusing it.
There’s a reason why manufacturers put that fancy “Recommended use” part on their product’s labels.
There’s even more scientific evidence suggesting that DAA doesn’t cause any harmful effects
Another study (2) reinforces the safeness of D aspartic acid, but this time the research subjects are only men (no animals were used as test subjects).
All of the 30 patients that were involved in the study were sub-fertile men and scientists wanted to see whether or not D-Aspartate (D-Aspartic acid) can help by improving their sperm quality.
After supplementing with 2.66 grams of the aforementioned amino acid for 90 days, they did blood tests that measured DAA’s effect on:
Red blood cells
White blood cells
The conclusion? No anomalies were observed in the serum measurements.
Or to put it simply – D-Aspartic acid DIDN’T cause any unwanted reactions.
That’s truly revealing, especially when you consider that these fellows were taking it for three months straight!
Does That Mean That Aspartic Acid Is Safe To Use?
Yes, according to modern science there are no reported adverse reactions, so you should be fine.
Many are wondering if testosterone supplements are safe or not.
But if you’re using a quality product from a trusted brand, then there’s nothing to worry about – including products that contain DAA.
Apparently, there are still some myths and legends surround this amino acid, especially when it comes to how safe it is.
So please, from now on forget about what anyone says regarding D-Aspartic acid if it’s not backed by science of course.
Just keep in mind that DAA:
Won’t cause acne
Won’t increase your aggression
Won’t cause excessive hair growth
Honestly, such side effects are actually the result of steroid abuse or having really high testosterone levels.
And it’s highly unlikely that any natural product (e.g. not an anabolic steroid/banned substance) will increase your own T production so much that you experience acne or increased aggression.
What Are Some Good D-Aspartic Acid-Based Supplements Out There?
Both single (containing only DAA) and multi-ingredient (including DAA among other ingredients).
Yes, testosterone boosting supplements do exist and here are a few great options that you can try:
1. TestoGen (The absolute BEST DAA-based T booster)
This is arguably one of the best and most effective testosterone boosters right now.
It contains heaps of D-Aspartic acid that’s one of the 11 science-based ingredients in this supplement.
Apart from a hefty dose of 2,352 mg of D-Aspartic Acid per serving, it’s loaded with other goodies such as Fenugreek extract and even Ginseng.
Oh, and don’t forget to check my very own TestoGen review to read about how I felt while taking it!
2. Nutricost – D-Aspartic Acid Capsules (3,000 mg)
This is not only a very affordable pure DAA product.
But it comes in capsules form that offers great convenience because you don’t have to deal with making shakes etc.
3. Bulk Supplements – D-Aspartic Acid Powder (3,500 mg)
If you prefer powdered forms, this unflavored DAA is pure gold.
It’s got 3 grams of D Aspartic acid per serving and the entire pack is 500 grams, which means that you have roughly 142 servings inside – talk about a sweet deal!
It’s crystal clear that the good old D-Aspartic acid is perfectly safe to use as a supplement.
There’s no particular scientific evidence that there are any particular D-aspartic acid DAA side effects associated with taking this amino acid, so relax and just give it a try.
Besides, DAA is one of the key ingredients in the particular supplements for low testosterone, along with other goodies that can help you to reclaim your masculinity.
And if you’ve ever used any DAA product or a test booster with DAA in it – have you experience ANY adverse reactions at all?

Should D-Aspartic Acid be Cycled?
Some experts recommend cycling D-Aspartic Acid, meaning taking it for a certain period of time and then taking a break.
This is because long-term use of DAA may lead to desensitization of the LH and FSH receptors, which could decrease the effectiveness of the supplement.
Three important pieces of information about cycling D-Aspartic Acid are:
- Some experts recommend cycling DAA to avoid desensitization of the LH and FSH receptors.
- The length of the cycle can vary, but typically ranges from 4-12 weeks.
- It is always important to consult with a healthcare professional before starting any new supplement, including determining the appropriate cycling schedule for your individual needs.
What is the Recommended Dosage of D-Aspartic Acid?
The recommended dosage of D-Aspartic Acid varies depending on the individual and their goals.
For athletic performance and body composition, dosages of 2-3 grams per day have been shown to be effective.
However, it is always important to start with a lower dosage and gradually increase it to assess tolerance.

Who should not take D-Aspartic Acid?
This supplement is not recommended for pregnant or breastfeeding women, or individuals under the age of 18.
But if you are unsure whether or not you should take D-AA, my advice would be to consult with your healthcare provider.
I’ve been fascinated by natural male hormone optimization since 2016. And ever since I’ve been going through boatloads of different meta-analyses and scientific data associated with increasing testosterone levels naturally. I hold a PhD degree in public health.
