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.

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”.

    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!

    Just started taking Thiamax but I think I am feeling more energy as I am getting more done in a day. Looking forward to continued benefits.

    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!

    Cleanest form of B1 out there, however you need to start slowly and make sure that your taking enough of other co-factors vits&mins to be able to assimilate B1 or else your going to crash.

    Great product. Prompt shipping. No complaints.

    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

    Very good product, I'd recommend it to anyone who is experiencing an illness that can be treated with thiamine.

    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.
