Thiamax contains thiamine tetrahydrofurfuryl disulfide, a derivative of thiamine (vitamin B1) with high bioavailability. This form has been shown to cross the blood-brain-barrier and can bypass normal routes of thiamine absorption, with a higher rate of uptake both in the gut and at the cellular level. Thiamax also includes a small amount of magnesium (as magnesium taurate), which plays an important role in supporting how cells can use thiamine.

Thiamax contains a highly-bioavailable derivative of thiamine (vitamin B1) called TTFD – thiamine tetrahydrofurfuryl disulfide. This form has been widely researched in Japan for its therapeutic potential in addressing thiamine insufficiency.

Unlike other forms of thiamine supplementation, TTFD’s molecular structure allows it to pass through intestinal and cellular membranes without the requirement for a transport system. Once inside the cell, it can be activated and used as a cofactor in important biochemical processes.



TTFD also has a demonstrated capacity to penetrate the blood brain barrier and increase thiamine levels in the brain and central nervous system, where it may be used to support optimal cognition and maintain autonomic nervous system function.

Due to its superior bioavailability, TTFD can be taken in much lower doses than what is considered the “therapeutic dose” of other forms such as thiamine salts. Thiamax also contains a small amount of magnesium (as magnesium taurate), which is a mineral that is important for supporting how cells can utilize thiamine.

Thiamax vs thiamine


How to use

  • Take one capsule per day with or without food.
  • Avoid coffee/tea consumption either one hour before or two hours after taking thiamax.
  • Avoid taking this product in the afternoon/evening, as it may interfere with sleep.
  • Should be taken alongside 200-400mg of magnesium & a high quality B-complex

For first time users who consider themselves sensitive to supplements:

  • Start with half or quarter of a capsule per day by emptying half of the capsule contents into a small glass of water.
  • Increase the dose every three or four days until you reach one full capsule.

Important information:

  • In some individuals, supplementation with Thiamax can induce a temporary worsening of certain symptoms such as fatigue, brain-fog, and digestive bloating or gas. This usually lasts for around one week, and is referred to as the “paradoxical reaction”.

    Honestly can’t tell if it’s making any difference, but that may not be the products fault. One of my doctors swears by it.

    The wife and I are utilizing Thiamax and monitoring our individual health concerns over various B1 deficiencies. To date no ill affects and apparently some positive effects. More time will be required for an accurate assessment of its effectiveness.

    A necessary form of Thiamin for some individuals with quick results, observed within 24 to 48 hrs significant improvements in clients’ cognitive and immune function. And yet another supposed neurological deficit is altered by a nutrient. So is it a nutrient deficit, or is or something on the scale between the two? The clients don’t ask those questions, so far they are just enjoying their increase in quality of living and functioning. I am grateful for learning more about High Caloric Malnutrition and the writings Chandler Marrs, PhD on Homone Matters, https://www.hormonesmatter.com/thiamine-deficiency-testing-understanding-labs/

    I had a sudden onset of severe muscle dysfunction 8 years ago, and gratefully with the use of Thiamax and the educational materials I’ve been able to rebuild my health. I’m walking unassisted and hiking mountains again!
