I was skeptical about this brand, since for a few months I used the GNC brand then switched over to amazing brand which I was not convinced it would offer the same nutritional benefits as the GNC counterpart, the formulation was identical, with one main difference based that this brand did not produce any side effects as the GNC brand did from time to time.The Best Naturals Gaba 750 mg Veggie caps, was a perfect transition since I could not detect any negative differences compared to the previous product that I was consuming, formulation was identical, package quality was excellent, the integrity of every capsule was perfect, I would have to actually run them through a lab to ensure that the formula is actually what the label states, all in all, great purchase, I have not lost any of the health benefits that GABA supplements offer.
