How Much TTFD for SIBO?
Thiamine is an interesting vitamin, because it comes in different forms. How much TTFD do you need for SIBO and IBS?
TTFD stands for thiamine tetrahydrofurfuryl disulfide, a form of thiamine (vitamin B1).

The Best Form of Thiamine for Gut Health
Vitamin B1 seems to be critical for gut health, which I find surprising because it is neither a probiotic nor a prebiotic.
Research has highlighted numerous detrimental consequences of thiamine deficiency on digestive function. These range from impaired gastric and intestinal motility to aberrant changes in pancreatic exocrine function, gastric acidity and disturbances in gut barrier integrity and inflammation. Thiamine and its pharmacological forms, as a primary or adjunctive therapy, have been shown to improve symptoms such as nausea, constipation, dysphagia and intestinal dysmotility, in both humans and animals.
Vitamin B1 Dosage for SIBO and IBS
When it comes to thiamine and gut issues, it is not only about the dose but also the form.
Although TTFD seems to work best for SIBO and IBS, it is also very potent, and some people need to start with less bioavailable forms to avoid flare-ups.
For sensitive individuals, Elliot Overton suggests the following steps:
Start low and go slow
- Start with a low dose (50 mg) of thiamine hydrochloride.
- Make sure to add a B-complex and magnesium (300/400 mg). The 3 can be taken together, no need to space them out.
- See how you respond and if it’s fine, double the dose (100 mg). It might take you a few days to adjust to a new dose or just 1 day depending on your general health condition.
- Increase the dose until you reach 300/400 mg. If you don’t experience any negative effects, you are ready for TTFD.
- Switch to TTFD.
How much TTFD for SIBO
- When you are ready for TTFD, you start with 50-100 mg.
- You gradually work your way up to 200-500 mg. Don’t forget about cofactors such as B-complex and magnesium.
Effective Dose for Different Forms
Thiamine HCL: between 500 and 2000 mg a day
Benfotiamine: between 300 and 1200 mg a day
TTFD: between 100 and 500 mg a day
Does it matter if you take thiamine in one dose or spread it throughout the day? Not really.
Can you combine different forms? Yes, depending on your health situation.
The Bottom Line
Unfortunately TTFD is not widely available, and in countries where you can find it, it may be quite expensive.
I highly recommend Elliot Overton's videos on YouTube if you want to better understand how thiamine and its different forms may support gut health.
