Your gut is trying
to tell you something.

Bloating. Sluggish digestion. That constant low-level discomfort you've learned to live with. New research links vitamin B1 directly to how well your gut moves, and most people are getting the wrong form.

What our B1
actually does for
the gut

Standard thiamine, the form found in most B-vitamin products is water-soluble, which can limit how effectively it reaches the cells that rely on it most, including those lining the gut and supporting the nerve signaling that drives digestion

Health by Principle's B1 with TTFD is different. It's fat-soluble, which allows it to enter cells more efficiently and support the tissues involved in digestive function.

What your gut actually needs to function: B1

Three essential roles B1 plays in digestion and why most people don't get enough where it matters.
01

It drives gut movement

B1 is required to produce acetylcholine, the signal that tells your gut muscles to contract. When B1 is low, that signal weakens. Movement slows. Digestion stalls.

TTFD helps deliver B1 where that signal is generated.

02

It powers gut lining repair

Your gut lining renews every 3–5 days a process that requires high cellular energy. That energy is produced in mitochondria, which depend on B1.

Without enough B1, repair slows and the lining weakens.

03

It regulates gut nerve signaling

B1 is required for proper nerve signaling. When levels are low, signaling becomes dysregulated, contributing to irregular motility and heightened sensitivity.

This is why disrupted B1 status is often associated with functional gut issues like IBS.

Our formula explained

What's inside and why.

ACTIVE INGREDIENT

TTFD Thiamine

Fat-soluble B1 derivative. Crosses the blood-brain barrier to support neurological function, mitochondrial energy, and cognitive health.

METHYLATION SUPPORT

Methylfolate (B9)

The bioactive form of folate, bypasses the MTHFR conversion step, supporting DNA repair, cellular health, and nervous system function.

ABSORPTION COFACTOR

Vitamin C

Ascorbate improves thiamine uptake and provides neuroprotective antioxidant support, helping maintain cerebral redox balance.

WHAT'S NOT IN IT

No stevia. No artificial sweeteners. No harmful fillers or artificial colors. Built for people who need a clean formula.

First of its kind! Formulated specifically around what the research actually shows about how thiamine works in the brain.
