The Good News
There is even some evidence suggesting that GABA aids in the release of chemicals which help to fight pain. Other inclusions in frontotemporal dementia proved to be tau-negative, ubiquitin-positive, a discovery that led to the separation of the frontotemporal lobe dementias: According to secondary sources, Ginkgo biloba has been used medicinally for thousands of years and is one of the top-selling herbs in the United States. Wild Yam, Yams Wild yam root supplement, wild yam cream, wild yam complex Clinical signs due to disc disease are rare in cats and horses. The body naturally produces Melatonin when light levels decrease in the evening to prepare the body for sleep, and levels are suppressed when light increases. The enthesophytes typically expand laterally and ventrally but not dorsally and therefore rarely affect the spinal cord.

Most of the evidence available on the bodybuilding results of this supplement comes from anecdotal reviews and user experience logs. The recommended dosage of GABA is dependent on many different factors including age, weight, sex, and the reason for taking the supplement. The following dosage recommendations are general guidelines only, and your personal dosage may be different.
It is always recommended that you speak with your doctor before beginning any new supplements to help determine the best dosage for your needs, as well as determine any potential negative interactions with existing medications or supplements. The recommended dosage range of GABA is between 3 and 5 grams per day. This can be taken all at once, although it might be more effective if the dose is divided into several equal administrations throughout the day.
If GABA is being used solely for the purported fat loss benefit, then the best time to take it is about 2 hours before sleep. Do not take this supplement with a protein source since it might affect proper digestion.
In research studies, it has been used safely for up to 12 weeks. GABA should not be used by women who are pregnant or lactating due to insufficient reliable evidence of safety. It has not been researched in these populations and it is not clear how this supplement may affect a developing or nursing baby.
This product is generally well tolerated as a dietary supplement. In some cases, mild adverse effects have been reported including constipation, reduction in appetite, stomach discomfort, nausea, fatigue, muscle weakness, increased body temperature and minor throat irritation. When administered intravenously, it has the potential to cause anxiety, reduced alertness, mood disturbances, increased blood pressure, changes in pulse rate and dysphoria.
In one study, GABA was administered alongside phosphatidylserine. A small number of gastrointestinal side effects were reported including constipation, nausea and severe gastric distress. One patient also experienced amenorrhea. In a study of children with Cerebral Palsy taking oral GABA tablets, some participants experienced nausea and a decreased appetite. Four children experienced convulsions and others experienced motor restlessness.
Excessively large dosages of GABA have been linked to impaired respiratory function. In one case, a dosage of 18 grams per day was found to induce short periods of breathlessness. The only known interaction with medications is with blood pressure reducing medications.
Use of this supplement alongside medications to treat hypertension may cause blood pressure to fall too low. Check with your doctor before taking this supplement with the following medications:.
Other effects of taking GABA can include being overly relaxed. You should avoid driving a vehicle or operating heavy machinery while in such a state. It is also important not to drink alcohol or do other drugs when taking GABA as this can lead to serious problems. Alcohol works by stimulating GABA receptors in the brain.
Combined use could result in excessive stimulation of GABAergic receptors, leading to increased feelings of intoxification. As has been stated, current scientific knowledge indicates that GABA supplements cannot cross the blood-brain barrier and cause any noticeable effect there. However there are many reviews online from people who have had positive effects using GABA supplements, whether due to placebo effect, potential blood-brain barrier hyperpermeability, or a possible connection through the enteric nervous system.
If GABA supplements give you the results you want then continue to safely use them. Hi JJ, Thanks for your response.
Not at all — the takeaway is to consider the research for any supplement you are using. Currently, the Natural Medicines Comprehensive Database states that there is insufficient clinical evidence available to rate the effectiveness of GABA for anxiety or stress relief.
Until more clinical studies are conducted to validate efficacy, it would be worthwhile considering the other supplements out there that do have clinical trials behind them to back up their purported effects. Thanks for your comment. This is sort of the reality when it comes to how side effects are reported and how products can affect different people.
For example, a small number of people who take caffeine report that it makes them feel drowsy and fatigued. Even though the majority of people experience increased alertness when they consume caffeine, this will still be reported as a side effect in comprehensive monographs.
We have different evidentiary standards for reporting side effects versus therapeutic effects. While the bar for demonstrating therapeutic efficacy is quite high, if one person reports a negative certain reaction when using a product during a clinical trial, it will get documented as a potential side effect.
This may be independent of findings of causality. Even though GABA is nothing compared to the supplements that allow it to enter the brain, it has its uses.
My breathing feels a bit labored, but this forces me to breathe more deeply, which relaxes me as well. It can actually be very mood altering especially at higher doses. In order for GABA to produce meaningful changes in mood beyond a placebo effect , it must first be able to access the brain through the blood-brain barrier.
Picamilon is a formulation of GABA and niacin that has been shown to penetrate the blood-brain barrier well. Picamilon has also been shown to restore the number of GABA receptors in the brain following: But the preponderance of evidence shows that it does not penetrate the blood-brain barrier well and Picamilon does.
Its located in your gut. I could probably end this entire post with that comment, but suffice it to say, neurotransmitters are in massive abundance in the intestinal system, and this is exactly why Gaba probably works for many people. There have also been studies showing that certain probiotics have significant anxiety-reducing effects, and well-being induction when taken orally. There is a direct connection between the gut and the brain.
Outside the brain, it is considered a hormone and not a neurotransmitter and it is also incapable of crossing the blood-brain barrier.
Serotonin has a number of roles outside the brain including regulating peristalsis, it is a growth hormone, it regulates milk production in the breasts and plays a role in cardiovascular function. To my knowledge, there have been no studies establishing that ingesting serotonin directly has a positive effect on mood, again due to the inability to pass the blood-brain barrier.
Could it simply be astroturfing on the part of those with vested interests in pharmaceuticals? I have found GABA to be a great anxiolytic and am always skeptical of studies that contradict the preponderance of positive anecdotal reports. A better research question is: GABA does not need to penetrate the blood-brain barrier to have physiological or psychological effects. This is the primary mechanism for probiotic anxiety reduction in mice: My wife is in worse shape.
Then again people like us have blood-brain barrier problems so we may very well get more out of simple GABA supplementation than other people.
We are also low on just about all the aminos essential or produced by the body. Or for that matter if somebody made a sinus inhaler for GABA it would go straight into the brain as there is no barrier to that method of administration.
Radiolabeled GABA was injected intraperitoneally and intraventricularly to the test animals. No significant amount of GABA that was injected intraperitoneally showed up in the brains of the mice or rabbits.
This conclusion persists today based upon this single study. This study was done in mice and rabbits, not humans. It was with intraperitoneally injected GABA, not from oral consumption. Certain metabolites of GABA were identified in the brain of these test animals and throughout other parts of the body, but this was not followed up.
Gaba is regulated as food. There are not prescriptions for it. Gabapentin is a very different drug. On an empty stomach I feel the effects within mins. Generally I will have about 30 secs with shortness of breath followed by a prickly feeling in my face. Or maybe neutralising the hormone.
I can actually feel the tension disappear over short period. This period of relaxation gives me the time I need to get my head in order. If one has a leaky blood-brain barrier then GABA can definitely get through. In fact you can use it as a test to determine whether you have a leaky blood-brain barrier.
If it has no effect, your blood-brain barrier is intact. The above either did nothing at all in my case or had worse symptoms that made me feel more sick than before. I did drop the coffee and pop, and replaced with green tea. It was not a placebo or something I could write off as a maybe or a fluke.
My chest tightness and pressure sensations in my sinus area subsided greatly and were replaced by a warm fuzzy feeling and greater sense of wellbeing. What turned me onto it was my doctor let me try Adavan as a way to see if Anxiety could be a cause or relevant issue.
It had similar positive effect on me, but because this medication is not for long term use it was not an option. I get the impression it is more for people who have occasional panic attacks and not a general chronic issue.
Actually I did read an article that claimed it is possible for some people to have a compromised blood brain barrier that could account for this.
Have done this so many times and it has never failed once, so for me at least the evidence of effectiveness is quite empirical. I have taken it on and off for over 5 years, but less often since it REALLY makes me hung over the next day, even at doses of mg.
Even drinking a large coffee could barely shake the fog. So has L-tryptophan but I tried that too and it makes me too groggy the next a. It is not placebo effect, each time I try a supplement I use a sleep app and I also write down dose and time, how I slept, wakeups, etc. In short, if you are a person with high anxiety, stress, racing mind, etc. My fiancee gave me gaba to help me sleep two nights ago. I read the bottle to understand the active ingredients and did not have any expectations other than it might help me sleep.
I think the placebo effect only works if you expect there to be some great change. Again, I had no expectations while taking a hippy dippy product. At least it definitely worked for me. I have a leaky blood brain barrier, haha.
If the positive outcome is the result of the placebo effect so be it. The outcome is what matters. For whatever reason Gaba works for me. My therapist and I both agreed that it worked. There is something here whether they want to admit to it or not. Something my doctor was not really amused with.
She wanted me on an anti-depressant and prescribed several. I have no doubt that GABA does not pass the blood brain barrier. But,the largest creator of GABA is not the brain but the digestive system.
Called the second brain our guts are also making GABA via intestinal bacteria. All of these could have killed off your GABA producing bacteria in your gut. And GABA is a known cofactor in some intestinal bacteris reproduction.
And then the cascade of issues start. While we believe anxiety is all in our heads- pun intended, it may be caused by something as simple as antibiotics or preservatives in food killing off the bacteria we need. If your body feels relaxed, then it is easier for your mind to follow suit. My muscles feel tense.
But after about a month on GABA, my muscles actually feel more relaxed and the feeling of things sticking to my skin feels more subtle and goes away eventually much quicker. I believe that our mind and physical state is strongly connected and that even just the physical sense of calm can induce the mind to calm as well. Just like the practice of Yoga induces brain calm and not that brain calm directly induces one to do Yoga.
Picamilon did nothing for me. No matter how low or high the dosage was. L-theanine works a little bit and phenitbut is the best one. These are the individuals who slowly slip into advanced stages of AFS. When sufferers experience frequent episodes of Adrenal Fatigue Syndrome symptoms that increase in severity and duration, this is considered this a sign of recovery failure.
There are many reasons for this failure, and Dr. Lam discusses seven of the most common in this book. Because adrenal crashes are invariably part of the recovery process, it is imperative that a sufferer has a comprehensive plan in place specifically to handle crashes and subsequent recovery.
In this book, Dr. Lam focuses on special tools and other considerations to be use to minimize crashes and maximize the recovery potential. By the time most women and men realize they have Adrenal Fatigue Syndrome, they are already in advanced stages. Many are surprised at the extent of damage done to their bodies, but few are surprised when they take a step back and do a detailed personal life history. Over the years, Dr. Lam has found that only a minority of sufferers developed Adrenal Fatigue Syndrome due to acute stressful events, such as accident, surgery, infection, and emotional traumas.
Most have had signs and symptoms of AFS for many years and even decades, but have ignored them for far too long. Acute events merely serve as triggers of adrenal crashes more often than not.
Lam will present a case study and explain the different stages of Adrenal Fatigue Syndrome to aid in your recovery. Only one out of every 10, people carries the longevity gene in his or her chromosome.
These fortunate few are likely to have a 20 year longer lifespan than the rest of the population. Some of them can become centenarians live to This process is largely regulated by the adrenal glands. Despite this important link, the connection between aging and the adrenal glands is seldom researched and often overlooked. Not enough emphasis is placed on the important link between subclinical adrenal dysfunction that occurs during the aging process in the modern world filled with stress.
Scientific evidence clearly shows that strong adrenal function is a key to good health. Conversely, weak adrenal function leads to pre-mature aging. Lam explains why any comprehensive anti-aging program should include a thorough understanding of how one ages and how to optimize adrenal function. Developments in modern medicine allow us a wide array of laboratory tests designed to help diagnose certain disease states, along with measuring the severity of the disease and the burden on the body.
There are literally thousands of tests available for your doctor to use. Lam will explain the correct ones to evaluate whether you have Adrenal Fatigue Syndrome, and help you understand the limitations of these tests. There are many misconceptions about Adrenal Fatigue Syndrome. Lam will explain some of the myths and common mistakes surrounding AFS to aid in your recovery. To fully appreciate the body's heroic effort to rescue us from stress, it is important to understand first that our brain is in control of our body through the neuroendocrine system.
What one person perceives as stressful may not be for another. Based on the perceived level of stress by the mind, the body automatically activates any or all of the anti-stress mechanisms in place by way of hormones and neurotransmitters. Michael Lam will delve deeper into how the body actually responds to stress and its ties to Adrenal Fatigue Syndrome. The body's hormonal organs are closely tied together through various axes.
Though lesser known than the HPA hypothalmic-pituitary-adrenal axis, the ovarian-adrenal-thyroid OAT hormonal axis is extremely important. When the OAT axis is disrupted, there is an imbalance of hormones that leads to symptoms of estrogen dominance, low energy, and hypothyroidism. Each component of the OAT axis affects the others. It also helps build strong bones and tooth enamel, and may speed wound healing or recovery from injury.
Threonine combines with the amino acids aspartic acid and methione to help the liver with lipotropic function, or the digestion of fats and fatty acids. Without enough threonine in the body, fats could build up in the liver and ultimately cause liver failure. Threonine supports the immune system by aiding in the production of antibodies, and because it is found largely in the central nervous system, may be helpful in treating some types of depression.
Threonine supplementation may also be useful for treatment of Lou Gherigs Disease, also know as Amyotrophic Lateral Sclerosis ALS , because it increases glycine levels in the central nervous system administering glycine is ineffective, since it cannot cross into the central nervous system.
Research indicates that symptoms of Multiple Sclerosis MS , another disease that affects the nerve and muscle function, may be lessened with threonine supplementation. One study showed that 7. Threonine is an essential amino acid, which means it must be obtained from dietary sources.
