I purchased these for myself (yes, I'm an adult) because I started experiencing persistent nerve problems. I had been using a different product (GABA), which doesn't have strong scientific backing for its ability to permeate the blood-brain barrier, but it seemed to offer some relief. The GABA supplement contained a B vitamin, prompting me to check with the Office of Dietary Supplements. I learned that B vitamins might not only be beneficial but I was likely deficient, especially since they are abundant in meats and I, being a vegetarian, don't consume much meat. ;) I opted for this "children's" version because the adult variants contain excessively high levels of vitamins, whereas this one aligns more closely with the recommended daily intake (RDA). Taking one twice daily, I notice a significant reduction in nerve issues, provided I'm regular with it. Plus, they taste good too.
