What is D-Aspartic Acid (DAA)?

D-Aspartic Acid is a relatively new ingredient to the market. It gained a ton of publicity and raves because of the study that showed it increased natural testosterone levels by 144% in just 12 days of use. But what does that 144% increase really get you?

John and Glenn dive in to this ingredient in this week's video and tell you more about what D-Aspartic Acid is, how it works and if it's really worth purchasing.

What is D-Aspartic Acid?

Video Transcription

John: Hello again, everybody. It's John and Glenn with Today we're gonna cover D-aspartic acid. It's the latest and greatest ingredient, I should say, used to increase testosterone. Specifically what it is is it's an amino acid. It's different than the typical amino acid we see. We're used to seeing L for the prefix for the amino acid. L and D just refers to the isomers of the amino acids.

Specifically our bodies are using the L-amino acids for building tissue and that's what you're finding in all your proteins. D, you'll see here and there like, in this case, where there'll be some specific effects of amino acid like sugars, for instance. There's L and D's. Our body uses D sugars, not L sugars.

This is the D form of aspartic acid. I wanna talk about some of the effects that have been found in some of the researches.

Glenn: Yeah, essentially it has been shown to increase testosterone in humans. There was human studies done at a 3-gram dosage per day or 3000-milligrams. It was only studied for 12 days. After 12 days, they had increasing testosterone of about 33%, which is good. It can be significant. After 12 days, they went off for 12 days and then went back on. It was sort of a 12 on, 12 off, 12 on, 12 off.

The way it works is, what it does is it increases your conversion of cholesterol into testosterone. Cholesterol and testosterone are essentially the same thing. They have the same backbone. Your body does convert cholesterol into testosterone but this increases that so you have more testosterone circulating in your body.

John: Now are there any other studies out there that have been done in humans or is this a relatively recent one?

Glenn: It's relatively recent. I imagine there are some... Well, there was some studies done back in the 90's on animals and things like that. I imagine there is gonna be some more human studies done on it. Yeah, it is a very, very hot item right now, very popular.

John: Some of the questions we're getting is it being a free-form amino acid, should people take it on an empty stomach? Most of these products are gonna have instructions on the bottles. I know some people have said to take it with food. Others have said without. I don't know. I'm just curious how detailed. We'd have to see what some of the future research comes out. Sometimes the problems when you're only dealing with one study is a lot of the questions and stuff that we have, there's just so many variables that we need to sort out and figure out over time.

These we've got in front of us some of the popular forms of it. A powder version here from Omega Sports. Like Glenn said, you got to take 3 grams. This particular one is 33 servings. You're looking at a little more of a month's supply. Now this one is a liquid form. This is a little bit different form, correct? This is a sodium-stabilized form of it, I assume.

Glenn: Yes.

John: It sounds like it's got a salt with it. This is a liquid. It comes in a little syringe-type thing, which is more for effect. You can suck it. You're squirting it into your mouth. It's not a syringe per se. It's just another way to take it. This is a liquid. Another powder here, PrimaForce, the D-aspartic acid. Again 33 servings based on a 3-gram scoop, so your month's supply. This one here, this is the newest one that we have. This is a little bit different. This is a methyl form.

Glenn: Yeah, N-methyl D-aspartic. It does have the original D-aspartic acid and then it has the N-methyl variety. I imagine that's there to help with the absorption or bioavailability of it. Maybe an alternative to the sodium-stable version.

John: I mean, it looks like there's a few other ingredients in here. It's a [inaudible 00:03:36], so we can't quite make out exactly what's in there. There are some other herbs in here that you'll see in some of the testosterone-boosting products. There's a little bit of zinc and magnesium. I guess, it's almost [inaudible 00:03:45] that Z.M.A. effect but not in that same ration that you'll see the patent form and a couple other ingredients in here.

This is a little bit different. This is capsule too. The recommended dosage on this one is they want you to take two to three capsules two to three times per day. If you're taking three a day, 90 capsules, it's about a month's supply. Right now, what's the most popular for us? Is it the powder or capsule?

Glenn: It's actually sort of a toss between the powder and the capsules. Sorry, not capsules -- powder and liquid. This is very popular and then the powder also. People, with the powder, just mix it with water or you can probably mix it with a protein shake. These products do say take with or without meals. Like John was saying, we don't know which is the better way to go or route to go because it's so new and the studies are so new.

John: Being a free-form amino acid, I tend to think on an empty stomach.

Glenn: I think so too.

John: Just 'cause you don't want any competitive inhibition, because in the presence of other protein, free-form amino acids tend not to absorb as well. Another question we get is, "Can people use this as a P.C.T.?" We've been [inaudible 00:04:45].

Glenn: It can be. It can be. It may not be as strong as needed like if you're taking an actual steroid or if you're taking a prolonged prohormone cycle. You may need some other ancillary ingredients or items, but it can be used as a P.C.T.

John: Okay. Overall it's nice to see that there's some human research on this. It looks pretty positive. Hopefully there'll be some more studies out. As those come out, we'll definitely keep an eye out for them. We could do a follow-up review. For those of you who are comfortable with that study to go off of, being that it was positive, it certainly made me want to [inaudible 00:05:20]. If you have any questions, please go ahead and post them in the blog or in the comments on the video. We're happy to answer them for you. Thank you.
