You're doing everything right, and yet...
Foggy by noon, still dragging by 3pm, still can't quite focus the way you used to?
The problem probably isn't your habits.
It's your B1.
Brain fog
B1 fuels the neurons that let you think clearly
Mental fatigue
TTFD feeds mitochondria directly
Poor concentration
Neurotransmitter support built in
Low energy by noon
B1 converts nutrients to fuel
We made it different on purpose.
Highest bioavailability
Most B1 circulates and leaves without reaching your brain. Ours uses TTFD, a form that actually reaches it.
Capsules per bottle
100-day supply at 1 capsule daily. More than 3× the supply of most competitors at a comparable price.
GMP certified facility
Formulated, bottled, and third-party tested in an FDA-registered, GMP-certified US lab.
Steady energy. No afternoon crash.
The 3pm slump isn't inevitable. B1 fuels the mitochondria your cells use to produce consistent, clean energy, not the spike-and-crash kind. When your neurons have what they need, energy holds through the day without stimulants.
Clearer thinking. Calmer baseline.
The mental clarity you had before the fog set in. B1 supports the neurotransmitters that keep you focused and emotionally even.
A nervous system that isn't running on empty.
When B1 is low, nerve signaling degrades. That shows up as brain fog, poor sleep, heightened stress responses, and the feeling that your mind is working harder than it should be.
Beyond the brain.
B1 is essential for proper cardiovascular function and skeletal muscle health. Supplementing the right form supports your whole body's energy infrastructure, not just cognitive performance.
Start feeling the differenceWhat's inside and why.
TTFD Thiamine
Fat-soluble B1 derivative. Crosses the blood-brain barrier to support neurological function, mitochondrial energy, and cognitive health.
Methylfolate (B9)
The bioactive form of folate, bypasses the MTHFR conversion step, supporting DNA repair, cellular health, and nervous system function.
Vitamin C
Ascorbate improves thiamine uptake and provides neuroprotective antioxidant support, helping maintain cerebral redox balance.
No stevia. No artificial sweeteners. No harmful fillers or artificial colors. Built for people who need a clean formula.
Not all B1 is the same.

Real routines. Real results.
“This is a great supplement. I feel so much more calm since I've been taking it. It does not have the garlic taste that I get with the other B1 supplements.”
“We all need this, but migraine sufferers need it even more. Thank you for providing exactly what is needed.”
“I definitely noticed a big difference when starting with this supplement. I just feel less anxious and my brain seems to feel quieter… I know this supplement works.”
