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”.

    This thiamine supplement has saved my life. I was having horrible symptoms, anxiety and really bad POTS. After years of drinking abuse and eating unhealthy, these symptoms made life and work unbearable. After so much research online I found the book Thiamine Deficiency Disease, Dysautonomia and High Calorie Malnutrition. Not long after I found Elliot content and then his supplement protocol.

    I started the sensitive protocol on Nov 1 and now it is Jan 3. I have had an improvement to my overall energy and mood. I used to want to take a nap every few days but now I can get through each day with no problems.

    I have a Thiamine deficiency so I know this product is working because my sleep and digestion are the best theyve ever been. It would be hard for you to relate but this changed my life. I had clinical insomnia and constant indigestion . They are completely gone after 34 years of staying up until 5am and having stomach pain after every meal. I just got lucky that I found about about Thiamine deficiency. If you have it this will work.

    I have a severe mold allergy and after much exposure, was left with dizziness, hypo tension, poor sleep, nightmares and chest pains. This product takes care of all of those symptoms. When I quit taking it for a few days all of the symptoms immediately return. This is the only product that helps and always is shipped quickly. It has been a life saver for me.

    Thiamax was the first product I tried from EO Nutrition with fairly good results for my idiopathic neuropathy back in 2021. Then when I paired it up with Thiamega & Benfotimine it was a game changer for me in 2022. I ran out last spring and slowly reverted back to having some major numbness in my feet which only continued to go up my ankles then up part of my calves. I seemed to get fairly fast results when I started back on it this fall. I was ever so grateful it worked again for me. I am trying to get up a stash of it up, so I don’t run out again. Thank you for such an amazing product Mr. Elliot. You Rock your natural world of health and healing. I wait eagerly for each and every podcast you post. They are so well done and give so much hope for those of us who suffer from ailments no one knows what to do with. May God Bless your heart young man.
