B1 – High Dose Thiamine Therapy

I first wrote about the B1 High dose Thiamine on January 31, 2020.


Then after researching more, I posted these findings on Feb 26th


I have documented progress I have seen in my personal life on my ‘Transparency’ Page.

I first learned about the B1 High dose Thiamine therapy through a post on HealthUnlockled . In a post by a gentleman with the User ID RoyProp. I learned about Dr. Costantini who was still functioning heading up the research in Italy. To learn about the research go to Facebook Parkinson’s thiamine hcl

If you click on ‘More’ and then ‘Files’ there were links to documents showing his research findings, but since Covid took Dr. Costantini away from us. I think the links may have been taken down. So I’m including one of the documents I cut and pasted:

“benefits are described by many members who are using or testing B-1”

By HU member ‘easily’. Carried over from healthunlocked.com/parkinsonsmovement

“I decided to go through the thread and list each benefit that has been mentioned by this group of B-1 testers and users from the HU forum.”

“Here is the list of symptoms that members have reported as being “reduced” by varying degrees to as low as zero or improved very significantly on the HU forum. About 95% of the list was compiled directly from the “who is taking thiamine” thread and the other 5% from other posts on the forum.

What follows is some testimonials from the HealthUnlocked

My regimen: by Roy Prop & then others…

The positives: 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 all motor and non-motor symptoms…

Entering my 7th year post diagnosis and have not fallen, not once, to the surprise of my neuro. Was seeing neuro every 6th month, last visit he set app one year. He said if needed we could do some changes earlier. He said my condition can change in as little time as one week.

New schedule, now I follow this regimen:

2 x day C/L 50-200 ER : 8 am, 5 pm. Because it is ER, I take with or w/o food.

2 x day (8 am 2g, and 5 pm 2g) Vitacost vitamin B1 (as thiamine HCL) 500mg, easy swallow capsules

B1 Thiamine therapy reference / stop progression, suppress motor and non-motor symptoms:

(Thiamine HCL is oral substitute to injecting B1) 2 x day (morning 2g and at lunch 2g)

Doctor Costantini strategy that I find helpful “thiamine hcl stops the progression forever…”.

Parky people say the first five years is your honeymoon stage with Parkinson’s. After that, progression more rapid.

I have gone from slow motion to normal motor action since joining the growing number of PwP that have started B1 regimen/protocol. –

Doctor Costantini – “Why is this? Because there is no medicine or drug that is able to affect all of the organs, whereas all of the organs function thanks to Thiamine. An important detail”, adds doctor Costantini, “the Thiamine therapy brings no collateral damage with time”.

I understand you are a little reluctant to start a higher dose (I was ,too!) but 100 – 200 mg may not make a difference. Based on your size (height x weight) i would start with 500 mg in the morning (before 10pm) and 500 mg in the afternoon (before 4 pm). I started with 2x 1g and now I’m at 2×0.5 g. I saw partial results after a week and full results after a month. You can gradually increase from 2×0.1 to 2×0.5 or even 2x1g but probably will take longer to see results. I think for you the best dose would be 2×0.5 which you can gradually reach in time. You need also to drink a lot of water to eliminate it. I take it from March 2018; the single symptom left is some tremor in RH. All the others are gone. Usually I take it on empty stomach with a piece of dark chocolate. Avoid citrus juices soon before and after taking it.

Good luck!

You can stop it for 2-3 weeks and find out. If you get worse, you can always go back on it.Reply (4)Report

For me it has made a tremendous difference, my balance , my driving, being able to sit up in bed and turn over in bed. Just recently, I stopped taking it for about three weeks and I noticed my balance was getting bed again. I restarted it at one pill of 500 mg a day and I’m just about back to the way I was before. With me thiamine HCL raises my blood pressure so that is why I stopped for a while.

I have been going to post for some time about my husband’s symptoms improving since B1, but wanted to find the correct dose first. He had also been taking 150mg CL daily (originally 300mg but reduced by using mucuna) since April ‘18, but he was still severely constipated (having once been hospitalized), had a foggy head, his balance wasn’t great, had difficulty swallowing, anxiety… the list goes on.

Dr C started him on 500mg x 2 in Jan ‘19. This was based on him being 6 ft tall, 68 kgs and 60 years old. After much experimentation, we have settled on 400mg x 2, and taking a break for one day every 10-14 days, or when my husband has an unrestful night sleeping.

Things that have vastly improved are:

No more constipation – this resolved after 3 days on B1

No more foggy head – that cleared after 6 weeks

Balance – slowly improved

Swallowing – at last review in May ‘19, the speech pathologist noted his mouth was no longer drooping on one side, swallowing and tongue functions were normal and he didn’t present like someone who has PD.

Anxiety – this has taken a good 6 months to get where he is, and there’s still room for improvement, but so much better.

Dr. Costantini has said it is fine to work your way up from lower dosing to higher dosing as a viable option to starting higher and seeing how you respond and then adjusting the dose accordingly based on your initial responses. Your method is much less likely to cause significant symptom deterioration as can sometimes happen if your first doses are too high. Working up from low to high maybe a bit slower, but if you are a B-1 responder, as the majority are, you’re going to be taking B-1 for life so there is plenty of time to adjust the dose as needed.


I KNOW this was a long blog entry… Congratulations if you stuck it out to the end.

In May of 2018, I was diagnosed with Parkinson's. After researching, I believe the symptoms began to manifest themselves years prior to last year. The purpose for my blog is to share what I have learned (with an index) to save others time as they seek for answers about, symptoms, therapies [and alternative things to try], tools I use, Parkinsonisms, recipes, strategies, clinical studies, words of encouragement or just enjoy the photos or humor.
