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.

SKU: EO1 Category:


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.

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”.

    After 5 days on Thiamaxx, B-complex and magnesium oxide, I was able to go off my medication for IBS-C. It has changed my life. I've been in turmoil with my digestive system for years and now, I'm simply not. I feel like it's a miracle.

  18. Lana Stredicke (verified owner)

    I haven't taken Thiamax for very long so I really can't comment on any affects yet. I have tried other forms of B1 recently and feel that I have landed on the right one. Daphne Bryan, author of 'Parkinson's and the B1 Therapy' and an interview of her by Elliot Overton is the information/therapy I'm trying to incorporate into my efforts to fight a diagnosis of Parkinson's I received three years ago. I am happy I received it in a timely fashion.

    On the photo of above Thiamax the cost is $22 (USA? or British?), in Canada, the cost is $37 CAD or so. Excellent communication with Damian: next time I place an order, I can use direct bank transfer to your account rather than using PayPal or Credit Card that does add an extra fee for converting US $ to other foreign $.

    For nearly two decades I have been proactive at finding what my body needs from supplements that I cannot do through diet. Thiamax is one that I could tell immediate results just after taking it. I have more energy, mental clarity and those last few stubborn pounds that were hanging on since I turned 40 are finally starting to go away. Out of all of my vitamins and minerals, this is one I will always keep on hand.

  36. Brian (verified owner)

    I have taken Thiamax for 2 weeks now. I started with 50 mg and now I have been at 200 mg for about 4 days. I am experiencing the paradoxical symptoms, which are not pleasant, but i am pleased to understand that it is more than likely working. At some point in the coming weeks I will possibly add a multivitamin and/or a B complex. The overall purchase and website experience was great. I am hopeful that my Thiamine deficiency can be fixed.

    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 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.

    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 have been using a vitamin B complex as well as benfothiamine, but I haven't had as much success as I did with Thiamax. I just took one capsule today and I can already tell my overall condition is improving (I must also say that I hadn't read the instructions about not drinking coffee before or after taking Thiamax and I did drink coffee one hour within my Thiamax consumption. So, I think me seeing results even with coffee depriving it is great news). Maybe next time you could put the invoice that clearly shows how much I've paid for the two bottles, since I had lots of problems at the customs. Great product, thank you!

    This Thiamax supplement is the FIRE. I was showing your product to a friend of mine. I gave him 2 100mg capsules and I took two also. 20 minutes later he said " dude, I can totally tell the difference from before I took these!" I said "I told you, bro"
    We are both big boys, and we both felt it -- laser sharp focus, a spike in energy, my vision felt like an eagle's. I love this stuff. The ability of this stuff to increase your energy, focus, concentration and visual acuity is obvious upon taking this supplement. I very highly recommend this product

    I have been using Thiamax for two months and I am completely satisfied. Neuropathy in my feet is much less severe, and seems it continues to improve. What I was not expecting and very happily surprised, my bladder control has improved. Just for the improved bladder control Thiamax is worth its weight in gold. For three months prior to starting Thiamax, I prepared myself by taking B100 complex, magnesium bisglycinate, benfotiamine, NAC, MSM, and Niacin. Also reduced carbs in my diet below 100 grams per day. On starting Thiamax for about 2 days I staggered while walking because of difficulty balancing on my feet. After that no problems.
