Does anyone know if K crosses the Blood Brain Barr

Does anyone know if K crosses the Blood Brain Barrier? Is it possible that the oral version of K will and the IV version does not? Probably unrelated but I had elevated mercury levels and DMPS was used via IV push to lower mercury levels down to a safer level as it did not cross the BBB. Months later I was put on an oral version of DMSA which did cross the BBB to further pull out mercury safely. Regardless of the answer to above CTIX having an oral version of K opens up tremendous opportunities. Long and strong.
