As many of you know, I have had a lot of success with the sublingual version of B1. I started taking it in 2017 and after a few months realised my slowness, my fatigue and my rigidity had all gone. I was diagnosed eleven years ago and since taking B1 have not increased my medication which remains at just 200 mg ldopa per day. Yesterday I came across this very good article on how to take sublingual tablets.
Sublingual B1 is thiamine monoitrate and I'm aware that thiamine hydrochloride (HCL) is the preferred form of B1 for oral administration. There has been talk of monoitrate being bad for the kidneys. I checked this out with Dr Lonsdale, a world authority on thiamine and he said "no" the sublingual B1, being monoitrate, is no danger to the kidneys. A sublingual tablet, if taken correctly, goes straight through the skin and into the bloodstream. Because it is so efficient you need far less of it than if you were taking the oral version. I started in 2017 on 1x 100 mg tablet a day and gradually reduced this over time, and now take just four tablets a WEEK.
Because someone will ask, I get the sublingual B1 from -
It is very cheap!
It does taste rather bitter but if you keep it firmly under your tongue while it dissolves it's not too bad and you do get used to it in a week or so. Do follow the instructions as to how to take it though. It won't work otherwise.
A doctor friend told me that all tablets would be sublingual if it was possible to make them into tiny enough particles to pass through the skin, as it was a much more efficient way of administration. Perhaps that's why they are monoitrate. Perhaps the hcl version can't be made into small enough particles. I'm just guessing. The main thing is that sublingual tablets can be monoitrate!
I hope this information is helpful.
