GABA safety in 5 gram dosages

Customer Question

I have just ordered a weight loss product called dream scape, it has Gamma aminobutyric acid in it says the servins size is 3 capsules and each serving size is 2 grams. Do you think it is safe to take this and it also says after the first week some people begin taking 5-10 capsules until they reach their desired wight, is that safe?

Here is what I found in my research:

"Talk with your caregiver about how much GABA you should take. The amount depends on the strength of the medicine and the reason you are taking GABA. If you are using this medicine without instructions from your caregiver, follow the directions on the medicine bottle. Do not take more medicine or take it more often than the directions tell you to."


  • Before taking GABA, tell your doctor if you are pregnant or breastfeeding
  • Do not take GABA if you have any of the following conditions: Prader-Willi Syndrome (1), Angelman Syndrome (1), encephalopathy (brain disease including dementia) due to liver disease (2), or behavior disorders (such as attention deficit hyperactivity disorder) (3)

Side Effects: Stop taking your medicine right away and talk to your doctor if you have any of the following side effects. Your medicine may be causing these symptoms which may mean you are allergic to it.

  • Breathing problems or tightness in your throat or chest
  • Chest pain
  • Skin hives, rash, or itchy or swollen skin

Other Possible Side Effects: You may have the following side effects, but this medicine may also cause other side effects. Tell your doctor if you have side effects that you think are caused by this medicine.

  • Visual field defects have been reported with use of the synthetic form of GABA (available by prescription only) (4)
  • Flushing, increased mood, anxiety, and increases in blood pressure and heart rate have been documented in animals given GABA (5) 7CGABA+%7C+&cid=HTALT

Normal daily doses of GABA in single-ingredient form, range from 250 mg to 1000 mg. In combination therapies that include Valerian, Hyperforin, Kava, Bacopa and vitamin B cofactors like B6 and B3, a daily intake of 10 mg to 100 mg is sufficient.

Hope that helped answer your question!

While taking it may be safe for most people, please review the side effects of the drug as mentioned above.

One thing to note, however, is that GABA, the ingredient in the drug, is a neurotransmitter, or chemical that helps nerves function. In pill form, there usually isn't enough of it to be ingested to cause, if any, weight loss.

There is no scientific evidence that this Dream Shape product works.

In fact, the FDA, reviewed statements claimed by one of the resellers of Dream Shape and said:

"The labeling of "InShape Dreamshape" bears structure/function claims, including the following:

* "In Shape Dream Shape is 100 grams of pure Gamma-Aminobutryic Acid (GABA) powder . . . . GABA is used primarily for fat loss as it has been shown to stimulate the body's ability to secrete the powerful fat burning hormone hGH during sleep."
* "People taking GABA tend to lose excess body fat."

We have reviewed these claims and have concluded that they are not supported by reliable scientific evidence. Because these claims lack substantiation, they are false or misleading, and cause your products to be misbranded within the meaning of sections 403(a)(1) and 403(r)(6)(B) of the Act. 21 U.S.C. § 343(a)(1), (r)(6)(B). It is a violation of section 301(a) of the Act to introduce or deliver for introduction into interstate commerce any food, including a dietary supplement, that is misbranded. 21 U.S.C. § 331(a). "
