Gamma-aminobutyric acid (GABA) is a chemical that is made in the brain. Because GABA that is made naturally in the brain has anti-seizureand anti-anxiety effects, there is interest in using it as a dietary supplement. But when taken by mouth, GABA is not able to cross the blood brain barrier. Therefore it does not have the same effects as drugs that increase levels of natural GABA.
GABA is taken by mouth for relieving anxiety andstress, improving mood, reducing symptoms ofpremenstrual syndrome(PMS), and treating attention deficit-hyperactivitydisorder (ADHD). It is also used for promoting lean muscle growth, burning fat, and for treatinghigh blood pressure,motion sickness,cerebral palsy,bronchitis, Cushing's disease,epilepsy, Huntington's disease,meningitis, a progressive brain disease caused by exposure to chemicals, and pain.
GABA is used under the tongue for increasing thesenseof well-being, relieving injuries, improving exercise tolerance, decreasing body fat, and increasing lean body weight.
How does it work?
GABA works by blocking brain signals (neurotransmissions).
QUESTION
Next to red peppers, you can get the most vitamin C from ________________.See AnswerPossibly Effective for...
- High blood pressure。Research shows that drinking 100 mL of fermented milk containing 10-12 mg of GABA daily at breakfast for 12 weeks reduces blood pressure in people with high blood pressure. Other limited research shows that taking a chlorella supplement containing GABA twice daily for 12 weeks reduces blood pressure in people with slightly elevated blood pressure.
Insufficient Evidence to Rate Effectiveness for...
- Cerebral palsy。Early research shows that taking one to four tablets of a product containing GABA (Gammalon) daily for 2 months might improve mental development, learning, vocabulary, and physical function in children with cerebralpalsy。
- Long-term infection of the airways in the lung (bronchitis)。Early research shows that taking 1.5 to 3 grams of a specific GABA product (Aminalon) for 18-20 days along with medications used for bronchitis increases the amount of time between symptom episodes by about 3 months.
- Cushing's disease。Early research shows that taking 1-3 grams of a GABA product (Aminalon) daily for one month reduces the release of the hormone that causes Cushing's disease.
- Seizures。Early research shows that taking 2.5 to 3 grams of GABA along with 500 mg of phosphatidylserine for 3-8 months reduces the frequency of a type of seizures called absence seizures in some people. But it does not benefit people who have partial or complex seizures or seizures triggered by lights or other visual causes.
- Huntington's disease。Early research shows that taking GABA alone or along with the drug dipropylacetic acid does not improve movement in people with Huntington's disease.
- Inflammation of the tissue around the brain and spine (Meningitis)。早期的研究表明,在0.5到1.5克rams of a GABA product (Aminalon) reduces the development of symptoms after recovery and prevents the development of other serious conditions in children 7 months to 16 years-old with meningitis.
- Motion sickness。Early research shows that taking 0.5 grams of a GABA product (Aminalon) 40-50 minutes before anticipating motion sickness or three times daily for 4 days slows the onset of motion sickness. GABA also reduces symptoms such as chills, cold sweats, and pale skin.
- Brain disorder caused by exposure to chemicals。Early research shows that taking GABA improves attention, memory, and emotional responses in children with a brain disorder caused by exposure to chemicals.
- Stress。Early research shows that taking 100-200 mg of GABA as a single dose prevents brain wave changes that are linked with stress. However, it doesn't appear to affect subjective measures of stress.

GABA seems to decrease blood pressure. Taking GABA along with medications that lower blood pressure might cause your blood pressure to go too low.
Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDIURIL),furosemide(Lasix), and many others.
The following doses have been studied in scientific research:
BY MOUTH:
- For high blood pressure: 100 mL of fermented milk containing 10-12 mg of GABA per 100 mL, has been consumed as a drink daily at breakfast for 12 weeks. A chlorella supplement containing 20 mg of GABA has been taken twice daily for 12 weeks.
