I ordered and have received prescription drug ALINAMIN F (5mg and 25mg) from Japan. It is Fursultiamine (another name for TTFD) as fursultiamine hydrochloride. I have an email stating that the hydrochloride comes off during digestion leaving the active ingredient TTFD for use in the body. I ordered, then had to send a wire transfer before they would ship. Currently there is a 33 dollar shipping fee due to fuel prices. I am not sure what normal shipping would be. Wire transfer fees was a few dollars using a service online. mimaki-family-japan.com/ite...
Here is a link to Elliot Overton's list of research links on TTFD: objectivenutrients.com/insi...
The smallest dose available in the USA is 50mg caps, which is much too strong for me.
