Does high dose thiamine cause constipation?

I know that some people have reported that high dose thiamine helps with constipation issues.

I have been gradually increasing my dose weekly having started at 100 mg a day and it seems to be causing constipation. I am currently at 200 mg twice a day.

Has anyone else found that high dose B1 causes constipation?

I am hoping I won’t have to discontinue it.

Thanks!

In my experience thiamine b1 doesn't cause constipation. I had constipation before I started thiamine. A short time after I started thiamine my constipation was greatly reduced. Though it didn't disappear completely

Thanks for your input, Grumpy. It’s great that B1 helped you.

Constipation is a symptom of Parkinson's. I take a level teaspoon of Mannitol, an osmotic diuretic which helps constipation and for some Parkinson's.

Thank you for your reply.

I didn’t have a problem with it before I started B1. I discontinued B1 for a week and the constipation improved. I’m now trying B1 again.

I experienced just the opposite - my constipation improved after some time on B1 injections. This was actually the only improvement I observed .................

How long before you saw the improvement?

About a month I think...............but due to Corona, I had to stop injections after 3 months and am now taking tablets but my constipation is worse again..........

That’s so unfortunate. Hopefully it’s not much longer until you can start injections again.

Thanks :) Still, I would also like to see some other improvements (tremor,r slowness of movement........) Did you see some improvements in other areas ?

I’ve been increasing my dose slowly over the past few weeks starting at 100 mg. Now at 500 mg and haven’t seen any improvement yet. How much are you taking?

300 mg - I am afraid to take more because these tablets contain some calcium and I have kidney stones. Did not look at the label when purchasing them :( but I do not want to throw them away so this is a compromise. I guess in the long run the dose will be too low...........

Diagnosed 2012

My regimen:

The positives after B1: no bradykinesia, I cut my food with a knife, no button difficulties, brush my teeth now w/o needing elect brush, more strength. Getting in and out of bed, turning over is easier. No more constipation. Parkinson's progression stopped. Suppressed most motor and non-motor symptoms...

Entering my 8th year post diagnosis and have not fallen, not once, to the surprise of my neuro.

Some people find a low-dose works well for them.

Yes, I am aware of that. It is really difficult to find the correct dose without any guidance.

I see you were diagnosed years ago - how have you been coping so far ? I mean medications, supplements, nothing at all?
