Thiamine - Vitamin B1

One of the next substances I wanted to trial for nootropic properties was Thiamine or Vitamin B1 which is water soluble. It is supposed to be involved in many neuroprotective processes and to aid in energy protection. Now a lot of people try a substance called sulbutiamine for the same purpose. Which is an analogue of Thiamine that is lipid soluble so it can pass the blood brain barrier more easily than it's older brother Thiamine. There is however one draw back it is much much more expensive compared to Thiamine. Thiamine alone is up 10x cheaper, and with a toxicity of 3g per kg of body weight and being water soluble, it will make an excellent addition to my upcoming homemade nootropic energy drink. Anyways I have some high hope as there seems to be a buzz about Sulbutiamine on some sites plus some research looks pretty good. And this on thiamine itself sounds promising too.
