hey what's up guys so i get a ton of questions regarding d-aspartic acid and uh to be quite
frank i understand why the research on d-aspartic acid is super confusing and on top of that um it's
almost impossible nowadays to find a testosterone boosting stack out there that does not contain
d-aspartic acid and so in this video essentially what i want to do
is dig through the research a little bit and then essentially come to a conclusion as to
whether or not d-aspartic sucks or not so let's go ahead and dive right in
this video is sponsored by let's get checked now d-aspartic acid is the d-isomer of the amino acid
aspartic acid which is the ionic form of aspartate and now aspartic acid and aspartate both have
several different roles in the human body however its most popular and
interesting mechanism is its possible role in testosterone production now when it comes to the
research on diasporic acid there are two primary categories of research one is the category of
research that has been performed on hypogenetic men and then the second class of research that
we're going to be looking at today in this video is uh the research that has been performed in
healthy young active men now the first study we're going to look at today is this study right here
where the researchers found that daily d-aspartic acid supplementation could increase testosterone
in young healthy active men by 22 at six days and 42 percent by day 12. and now obviously this
is super promising however when we look at this study that found completely conflicting results
um this study in particular found that there was absolutely no increase in testosterone at
30 days of supplementation now the current theory that has been proposed in several different places
is that d-aspartic acid may be able to increase testosterone levels in young healthy active men
for around two weeks whereby it subsequently decreases back to baseline by day 30. however
i don't think this theory um is entirely accurate simply because d-aspartic acid actually
builds in effectiveness over time and so you would expect that if there was a 22 increase at day 6
and then a 42 increase at day 12 that you would expect that there would be some level
of improvement at day 30 as well however in that second study that we referenced it is somewhat
clear that at least in young healthy active men that diasporic acid doesn't have an effect on
testosterone levels and so what i think is more likely going on here is that if we take a closer
look at that first study that was referenced you'll see that the participants of that study
were actually recruited from a fertility clinic and so it actually doesn't look like these young
healthy active men were young and healthy so it is extremely likely that these men may have
had some level of hypogenatism or some level of disruption in testicular function and this is why
it's so important to actually read studies before drawing conclusions about specific compounds even
though the researchers of this study described these men as young and healthy again it doesn't
really appear that that was necessarily the case and so all in all when it comes to the research
on d-aspartic acid in young healthy active men i don't think the research is super promising for
that specific cohort of individuals however when it comes to the research in hypogenetic
and infertile men i do think the research is a whole lot more promising now in this study in
particular that was performed in hypogenetic infertile men there was roughly a 30 to 60
percent increase in testosterone levels and the aspartic acid was also apparently highly effective
at increasing sperm parameters fertility rates and pregnancy rates as well which is extremely
promising because it shows that diasporic acid isn't just a compound that may improve
testosterone production but also may improve testicular health as well now in this study as
well the uh researchers actually overall didn't find a statistically significant improvement
in testosterone production however when the the cohort of subjects was stratified into subgroups
the group that had uh clinically low testosterone did see about a 20 increase in testosterone levels
over the course of a month and so when you take these two studies in combination with
the original study that was referenced it does appear that uh d-aspartic acid does have
some level of effect on testosterone production at the end of the day as well as testicular function
which is extremely promising however again it is also worth noting that if you are a young
healthy active man in your 20s that you probably won't see a significant difference in testosterone
levels by taking something like d-aspartic acid now when it comes to the mechanisms of action here
i do think this is fairly interesting there are three specific mechanisms of action that i want
to walk through here and the first one is that d-aspartic acid seems to increase and directly
stimulate the hypothalamus to stimulate the pituitary gland to release genetic tropic
hormones such as luteinizing hormone and follicle stimulating hormone now another super interesting
mechanism of action here is that d-aspartic acid also appears to augment the effects of
hcg on testosterone production and so this isn't entirely relevant to everyone however if you are
taking something like hcg for fertility purposes it does appear that d-aspartic acid actually
improves the responsiveness of the lytic cells to produce testosterone in the presence of
hcg now the third mechanism of action here appears to be that d-aspartic acid is able to
increase the expression of a protein known as the star protein which is a protein that's highly
involved in the conversion of cholesterol into sex hormones and so by obviously increasing the
expression of this protein there is a theoretical improvement and the ability of the testicles to
take cholesterol and actually turn it into testosterone so now all in all when it comes to
d-aspartic acid and testosterone production again i don't think it is a good choice for
individuals that are in their 20s and looking for just a testosterone boost it's probably not
going to work in that manner however if you're someone like myself who has past ped use and
are trying to jumpstart your natural production of testosterone maybe after a cycle or are trying to
lower your trt dosage the aspartic acid may be an effective tool kind of like as an adjunct to
jump start the stimulation of the hypothalamus to stimulate the leather cells of the testes to
produce testosterone on its own again now with all that being said in reference to testosterone
there's also another interesting mechanism of d-aspartic acid that i want to touch on in
this video and that is its possible cognitive enhancing properties as well now the research
here is extremely preliminary however there is a singular rodent trial that does suggest that
supplementation with d-aspartic acid may improve cognitive function to some degree
and now there are a couple of different mechanisms that may be at play here one is
that d-aspartic acid does appear to improve nmda signaling in the central nervous system and now
the nmda receptor is a receptor that is uh stimulated by glutamate as well as some other
minor neurotransmitters however the nmda receptor is highly involved in the consolidation of memory
as well as alertness and so by theoretically being able to stimulate this receptor d-aspartic acid
may have somewhat of a a cognitive enhancing properties to it as well and not only does
d-aspartic acid appear to stimulate the nmda receptor but it also appears to have some level
of involvement in dendritic outgrowth of neural cells which are the kind of like the branches in
the spines that branch out from neurons in order to connect with other neurons and so
there is a lone study that implicates d-aspartic acid at improving dendritic length by up to 40
which is again somewhat promising for d-aspartic acid as a nootropic compound now with all of that
being said i am somewhat of a fan of the aspartic acid it's been in my cupboard for
several years now and i take it on and off um to be quite frank i don't notice a
ton of difference with it which is why i don't really recommend it to a lot of people however
the research is somewhat decent on it and so if you are particularly hypogenetic and are
looking for something to naturally stimulate the production of testosterone again it does seem to
be a good option and because it is just simply an amino acid it has an extremely high safety profile
and doesn't need to be cycled and so it's just a really simple supplement for a lot of folks that
are looking for kind of just something basic to start out with when it comes to jump starting the
hpg axis now if you're looking for natural ways to increase testosterone levels one of the first
steps is going to be actually getting a complete hormone profile done everyone's hormones are at
a completely different place and so there just really isn't a one-size-fits-all approach to
optimizing your hormone profile the approach that is effective for one guy may actually be
detrimental to another and so if you haven't had your hormone profile checked yet i would
highly recommend looking into my friends over at let's get checked they have one of the most
comprehensive tests on the market and what's more is that you can actually do it at home now this
is a super sweet deal so make sure to check out the link in the description down below for 30 off
of your test but other than that guys if you're looking for more proven supplements that can be
used to safely increase testosterone levels make sure to check out the free guide that i have on
my website but other than that guys i think that's all i have for you today if you have any questions
feel free to leave a comment down below and i will see you guys next time thank you so much
