Welcome, everybody. It's so nice to see so many
0:03
of you here this morning. So I'm gonna be talking about GABA.
0:06
What's GABA got to do with it? R.
0:09
I. P. My name is Dr Scott.
0:11
Sure. I'm the chief operating officer of Health
0:13
Optimization, Medicine and Practice. Our nonprofit organization training
0:16
doctors like you and practitioners
0:19
like you how to optimize health rather than treat disease and treatment.
0:22
I have a lot of fun with this talk.
0:24
I've, this is something that actually Dr.
0:27
Ted and I, but mostly Dr. Ted developed as a strategy for
0:31
our overall understanding that
0:34
nobody remembers the most important neurotransmitter in our opinion, GABA.
0:39
Everybody remembers serotonin and dopamine and norepinephrine.
0:42
These, these are the fancy ones. Everybody knows about these, but
0:45
everybody forgets about GABA.
0:47
So this is going to be a talk on how GABA is made, what GABA
0:50
is and why we should care. Let's talk about top
0:53
symptoms of GABA deficiency.
0:56
So if you have a clinical practice, you probably have some of your
0:59
patients with these symptoms. Anxiety, fear, depression, a short temper,
1:04
phobias, impulsiveness, disorganization,
1:08
addictions, schizophrenia, obsessive compulsive disorder.
1:11
Any of your patients have any of these? Probably, right?
1:13
But you're not thinking about GABA deficiency most of the time.
1:16
And then systemic symptoms, these are also associated with GABA deficiency.
1:20
IBS, diarrhea, high blood pressure,
1:22
tinnitus, chronic pain, migraines,
1:24
allergies, frequent urination, flushing,
1:27
sweating, salt cravings, muscle tension.
1:30
So all of these, could potentially
1:32
be showing you that your patients and clients may have a GABA deficiency.
1:37
It's not the first thing on many of our radars, of course, but maybe
1:39
it should be part of that initial understanding of what might be going on.
1:44
GABA is really important, and now even
1:48
the drug industries are getting the idea.
1:50
So this is the first drug Approved just recently.
1:53
This is a New York Times article. The first pill for postpartum depression.
1:57
And it's called, Zuranolone, I think is how you say it.
2:01
And it is a positive allosteric
2:03
modulator of the GABA receptor. We'll talk about what that is.
2:05
But it's supposed to be used for the first 14 days.
2:08
Only for two weeks. Supposedly, while you're taking another
2:10
drug like an SSRI for that to work, but these work right away because
2:14
it's affecting the GABA receptors s directly and improving depression almost
2:18
immediately, too, which is pretty awesome. You don't have to go directly to drugs, of
2:21
course, but sometimes they're necessary. So, let's talk about GABA synthesis.
2:24
GABA is only made in the brain. Okay, you have to have glutamine,
2:28
which is an amino acid, it's converted into glutamate.
2:32
in the brain. And then glutamate is our
2:34
excitatory neurotransmitter. And you have GABA, which is our
2:37
inhibitory neurotransmitter. So 20 percent of the brain's
2:41
neurotransmission is actually GABA.
2:43
So it's a huge amount. And glutamate in GABA combined
2:46
is about 80 percent actually. So it's the combination of the two is the
2:49
majority of your neurotransmitter system.
2:52
And to make glutamine into GABA, you need.
2:56
You need this enzyme called glutamine synthesase. And then from glutamate to GABA itself,
3:01
you have to convert this, you need vitamin B6, and you need magnesium.
3:04
So you need cofactors along the way to make this conversion happen.
3:08
Some people are really great at converting GABA into GABA.
3:11
Some people are not very good at it. And a lot of times it's related to these
3:14
cofactors, but there's other reasons, too. And see, here are some of those reasons.
3:18
So, If you have a high copper level
3:20
and a low zinc level, you're not going to be able to actually have the
3:23
GABA receptor work as effectively. If you're vitamin B6 deficient, you're
3:27
also not going to convert well from glutamate to GABA, as I mentioned.
3:31
If you have chronic stress, if you have chronic hypercortisolemia, if
3:34
you're always stressed, you're going to deplete your GABA system, and then
3:37
your GABA levels are going to go down. If you're magnesium deficient, and
3:41
most of our clients and patients are magnesium deficient, they're
3:44
not going to convert well either. If you have infection, this
3:47
is going to stress the system and also decrease GABA levels.
3:50
Now, GABA supplementation may help your
3:54
GABA levels, but actually under most circumstances it's not going to because
3:57
GABA itself is a big molecule and doesn't
4:00
go across the blood-brain barrier. Under , certain circumstances, it
4:02
may, and we'll talk about that. And then probiotics can also help with
4:06
this conversion, help with this enzyme. So, you can actually measure, and
4:09
you saw some of these slides with Dr. Ted, you can actually measure
4:12
people's vitamin B6 level, and if
4:14
it's low, it's very likely they're not converting well from glutamate to GABA.
4:18
So this is something to be thinking about, and this is why we do
4:20
metabolomics testing as well.
4:24
You can check their magnesium level. In this patient, in this client, it
4:27
was a normal magnesium level, this is red blood cell magnesium, but a lot
4:30
of our clients, it's going to be low. So if you have a low magnesium
4:33
level, if you have low B6 levels.
4:35
You're not going to convert well from glutamate to GABA. This is the GABA receptor.
4:40
You don't have to worry about this too much. Just to know that it's a pentameric structure.
4:44
It's got five subunits. And these subunits change depending on
4:47
where the GABA receptor is in the brain.
4:49
Sometimes they'll look one way and
4:51
they'll have various combinations depending on what they're doing. GABA is everywhere in the brain.
4:55
These GABA receptors, the subunits change depending on what's required and
4:58
what's going on in that particular area. So this is the mechanism of the
5:02
GABA receptor, so we're going to start with GABA A here.
5:05
So you have activation of the receptor, you have opening of the central pore,
5:09
you have influx of chloride, you have hyperpolarization, you have decreased
5:13
occurrence of the action potential. So this all is saying that you're
5:16
inhibiting the actual firing
5:18
of this particular neuron that has the GABA receptor.
5:21
So you're inhibiting the action potential. So you're stopping things, you're
5:24
calming things down in general. Chloride goes through,
5:28
and it hyperpolarizes. This is the GABA B receptor.
5:32
It's called a G protein couple receptor. It's a little bit different, and it's
5:35
called a metabotropic receptor, and I'll show you what this means in a minute.
5:38
This is GABA B. So, GABA B itself, what it does,
5:41
it's a presynaptic and postsynaptic.
5:43
So, presynaptically, it's preventing, here, the release of an excitatory
5:47
neurotransmitter, glutamate, which is what we've been talking about before,
5:50
is the conversion of glutamate to GABA. And then you have the postsynaptic, here,
5:53
which is increasing potassium outflux,
5:56
which causes the hyperpolarization. It's a little bit different, and
5:59
there's a different distribution of the GABA B receptors in the brain.
6:03
So here's a quick summary. So GABA A is, it's called an ionotropic,
6:07
or it's a ligand gated channel opening, and it's a pentamer structure.
6:10
It's widespread as post synaptic influx.
6:14
It's endogenous agonist is GABA.
6:16
You have other drugs acting on it, which we'll talk about in a minute.
6:19
Pharmacological actions here and then
6:21
GABA B is, as you see here, it's
6:24
also widespread, it's metabotropic, it's presynaptic and postsynaptic,
6:28
and it has these particular, pharmacological actions as well,
6:31
all right. So. There's a couple definitions here.
6:34
So orthosteric ligands, these are chemicals that interact with
6:38
the same binding site as the natural endogenous chemical.
6:41
In this case, we're talking about GABA itself.
6:44
So an allosteric ligand or allosteric
6:46
modulator is something that works by
6:48
modifying how the receptors behave when it's bound to the orthosteric ligand.
6:52
So in this case, we're talking about a separate site.
6:54
away from GABA that binds this
6:56
particular modulator and then makes
6:59
GABA work better or helps the binding or
7:01
improves the chloride channel opening. And then a positive allosteric modulator
7:05
is something that binds and it causes this positive response where you have
7:08
an increased affinity of GABA to bind, you have more chloride going through,
7:12
and you have more hyperpolarization. So this is a picture of the
7:14
GABA receptor and ligand. So here's a couple, examples of
7:17
what it looks like to have where GABA is binding and where some of
7:21
these other drugs will bind to.
7:24
So you have alcohol everybody used
7:26
to love or maybe still loves alcohol. It's got a very high affinity
7:30
for the GABA receptor. Very, very high affinity.
7:33
Benzodiazepines here, very
7:36
high affinity as well. Has anybody ever used Flamazenil before?
7:39
I used it a couple of times in residency, I don't recommend it.
7:42
It causes seizures because it has the opposite effect.
7:45
GABA antagonist, so it prevents the chloride channel from opening.
7:49
Zolpidem, which is the Z drugs, Ambien and others, they bind and bind
7:53
very tightly to the GABA receptor. Quaaludes, anybody ever tried a Quaalude?
7:57
I don't know how everybody, yeah. Dr. Ted, no, no.
8:00
This is back in the 70s. So, but they also were, , A GABA
8:03
binding here, an allosteric site, barbiturates, which we use sometimes
8:07
for alcohol withdrawal, actually. Sometimes we'll still use those,
8:10
but for pretty much not used otherwise, general anesthetics.
8:13
And then finally, the GABA is where it's GABA binding itself.
8:16
So that's where GABA is binding. And so all these other sites on the
8:19
GABA receptor are places where other
8:22
molecules can bind, increase or decrease
8:25
the affinity of GABA binding and increase or decrease chloride channel opening.
8:29
It's on the right side of your screen over there.
8:32
You can see just a top view of the same thing happening.
8:34
Benzos are probably the most common positive allosteric modulator of
8:38
the GABA receptor that we use. Unfortunately, Benzos
8:40
have a very high affinity. We're talking about Ativan,
8:43
Xanax, Valium, those kinds of
8:45
drugs have a very high affinity. affinity for the GABA receptor.
8:48
So when somebody is taking these
8:50
medications for long periods of time, they cause tolerance, they cause withdrawal,
8:53
they can actually cause hallucinations
8:56
and death and all those fun things too. So, but you can see here that what I
9:00
wanted to point out is that there's different subunits of the Alpha
9:02
1 subunit of the GABA receptor is
9:04
associated with sedation hypnosis. So this is actually a lot of
9:06
your Z drugs, like your Ambien's
9:09
and Lunesta's of the world. And then your Alpha 2 subunit is.
9:12
It's more of your anxiolytic and muscle relaxer.
9:15
So this is where your benzo is going to mostly bind.
9:17
So in general, positive allosteric modulators are less addictive overall.
9:23
However, that's not the case obviously for benzos and barbiturates and alcohol.
9:28
And some of the natural equivalents that we'll talk about do have less of affinity,
9:32
but still have significant impact. So drugs that act on the GABA
9:35
B receptor, the most famous being, GHB gamma hydroxybutyrate.
9:39
GHB is well known as the , date rape drug. But it's actually a fantastic drug
9:42
for muscle relaxation, sleep, and
9:45
has lots of great other indications,
9:47
including narcolepsy actually. If anybody lives, listens to our podcast,
9:50
the Smarter Not Harder podcast, I had a
9:52
really great conversation with a guy named Dan Party, who was involved in getting
9:56
GHB to market for pharmaceutical reasons
9:58
with very interesting talk with him. So we're going to switch over here.
10:03
So GABA cell GABA in general.
10:06
The cells that have GABA receptors are mostly what we call inter neurons.
10:10
These are neurons that are between neurons, inter neurons,
10:13
and they're really important for learning, for memory, for behavior.
10:16
They're kind of like the way stations between sensory and motor
10:19
processing, and even though they're
10:21
really small, like if you can't really see here, but it's a tiny one.
10:24
Like, the GABA here, but this is the big dopamine receptor, , neuron, the big
10:27
5 HTP, the big serotonin neuron here. But you have, like, the small GABA.
10:31
This is doing a lot of the processing between them.
10:34
So they're extremely important, and they're actually in these locations
10:37
to make sure that they can actually be those wave stations to prevent signaling.
10:41
Oftentimes, in our brain, it's actually preventing signaling
10:43
that's most important, not propagating, interestingly enough.
10:47
Okay. So we're going to talk about how
10:49
you can dim your GABA switches without a prescription required.
10:52
And, but the first thing to say is that most GABA supplements don't work.
10:55
And we, and I was mentioning that earlier, it's because GABA is such
10:58
a big molecule, it doesn't get across the blood brain barrier.
11:01
If you do have patients that are taking GABA and they are getting an effect,
11:05
it could mean that they have a leaky brain, leaky gut axis, potentially.
11:09
There are some formulations, maybe nanoliposomal, for example, that may work.
11:12
But in general, if they're getting a significant impact from GABA itself,
11:16
at least clinically, I've seen that they often have a leaky gut, and that
11:19
usually means they have a leaky brain. I don't like telling patients
11:22
they have a leaky brain because that doesn't sound that great. I usually say that your
11:25
blood brain barrier may not be as great as it should be.
11:28
But anyway, so you can also, of course, give glutamine and glutamates.
11:32
So glutamine is an amino acid, it's
11:35
in various types of foods, meat,
11:38
Spinach, and fish as well, of course.
11:40
And so you can get glutamine from a lot of different sources, but what we do in
11:43
health optimization medicine and practice, we test for these kinds of things.
11:46
We test vitamin B6, we test for magnesium, we test their
11:50
glutamine levels, and we can tell. And if they have a certain symptomatology
11:53
and they have certain co factor
11:55
deficiencies, well, you know, we know that they're probably GABA deficient too.
11:58
MSG. Everybody loves MSG. Everybody actually doesn't love MSG.
12:01
It's monosodium glutamate, right? This is what you can get
12:04
in Chinese restaurants. They make the food nice and sweet
12:06
for you, but you get a headache. That's because you get all of a sudden
12:09
this huge rise in glutamate, and you have
12:11
to get that conversion over to glutamate, to GABA, and that can take some time.
12:16
And nicotinyl GABA. So this is a really cool form of
12:19
GABA that's attached to a vitamin B3. And when you do this, you actually
12:23
allow this molecule, nicotinyl GABA, to get through the blood
12:26
brain barrier very easily. And then it hydrolyzes
12:28
to vitamin B3 and GABA. And when that happens, you get this
12:31
nice vitamin B3 effect, which is mild vasodilation and mild energy
12:35
production, , At the same time, your
12:37
GABA itself, getting into the brain, increasing, your GABA ability and
12:41
increasing GABA binding to its receptor. So relaxation.
12:44
What's nice about this is it's not very sedating for most people.
12:47
So if you have anxiety and stress during the day, you can take nicotinyl
12:49
GABA and you don't feel tired. You just don't feel stressed, anybody use
12:53
valerian root before for patients, right?
12:55
So very common. This is actually a valerian
12:58
root, something that actually binds to the benzo site.
13:01
So it's a positive allosteric
13:04
modulator of the GABA receptor. Doesn't bind as tightly, but it does work
13:07
really well for some people for sleep. Covain, which is the
13:10
active ingredient in Kava. It's actually a similar binding site.
13:13
Also a positive allosteric modulator of the GABA receptor.
13:16
Honokyl. Anybody used Honokyl as well?
13:19
So this is from Magnolia Bark. Also binds as a positive allosteric
13:23
modulator to the GABA receptor.
13:25
Works really well, for a lot of people. Does anybody know what this is?
13:30
It's a mushroom it's a very famous mushroom. It's called Flyagaric, or
13:34
Amanita muscaria is the other name for it, of Christmas lore.
13:38
Does anybody know about the Christmas tales of Amanita?
13:41
Amanita has two compounds in it, mostly.
13:44
It's got a lot of other things, but two major ones. One is called agarin, otherwise
13:48
named muscimol, and another one is called ibotenic acid.
13:52
Ibotenic acid is neurotoxic. This is the one that mostly causes
13:55
the psychedelic experiences of
13:57
taking this particular mushroom. But, you don't mostly take
14:00
this mushroom directly. The stories were that shamans would
14:04
drink the urine of reindeers, because
14:08
reindeers would be able to tolerate this.
14:10
Okay. And then the shaman would actually then urinate.
14:13
And then other people would drink the urine. This is in Northern.
14:17
You can, this is actually a great New York times article on this with some
14:19
great videos as well, but that's mostly because the toxicity is because of
14:22
ibotenic acid, but agarin or muscimol
14:25
is a fantastic orthosteric ligand of
14:28
the GABA receptor, which means That it
14:31
directly enhances GABA in the system,
14:33
and it does it very effectively. But the key is to have
14:36
it at very low doses. So it's a GABA receptor agonist.
14:39
It easily crosses the blood-brain barrier. It's got a high potency, it's long-acting.
14:42
It's about 6 to 10 hours overall for a half-life.
14:46
It's naturally occurring, or you can make it synthetically, in low doses.
14:49
It's safe and effective. And at high doses it can be
14:52
hallucinogenic, but usually in, in combination with the Ibotenic
14:54
acid and the actual musher. Non pharmacologic, of course, yoga,
14:59
meditation, breathwork, anything that's going to make you more
15:01
parasympathetic is also going to increase GABA tone in the brain.
15:05
Physical activity also helps reset the system and the balance between glutamate
15:08
and GABA, so also being physically
15:10
active is also really important. And then, finally, it's really
15:14
important, and this is kind of the ethos of health optimization medicine
15:18
and practice, is we're detecting and correcting at the metabolomic level.
15:22
And so, you really want to be keeping the GABA deficiency aspect
15:25
of things on your clinical radar. So we test for the nutrients.
15:28
We test for magnesium. We test for vitamin B6. We ensure optimized GABA production.
15:33
And you want to do that as sort of your baseline for everybody.
15:36
So when somebody comes to see me, I'm not looking for GABA deficiency exactly.
15:40
What I'm doing is doing a full metabolic, metabolomic profile,
15:43
correcting as I see, and then you often
15:46
will see these improvements in mood and depression and anxiety because
15:50
you're actually working on that. neurotransmitter system.
15:52
Sometimes you can give herbals and you can give supplements and
15:55
things like that to help right now. That's what the company, the
15:58
transcriptions company is all about. But the key for the long term is to really
16:02
work on that foundation and optimize it. Of course, you want to implement dietary
16:05
and lifestyle measures to boost GABA production, considering herbal and fungal
16:09
GABA agonists and orthosteric ligands to support GABA production as well.
16:13
And then you want to really want to avoid your benzos and your barbiturates,
16:17
obviously, and drugs that are going to
16:19
cause dependence, withdrawal, intolerance. I mean, that's just important
16:22
for us to think about. Sometimes it's unavoidable and I use
16:25
these in my patients when they really need it, but oftentimes we can get
16:28
away with not using them because we have a lot of great options here from
16:31
an herbal and fungal perspective. Thank you guys very much for listening.
16:36
I really appreciate your time.
