Clinically-Approved Thiamine Supplement

Thiamax, one of the leading and clinically-approved thiamine supplements in the US, contains thiamine tetrahydrofurfuryl disulfide, a derivative of thiamine (vitamin B1) with high bioavailability, making it the perfect natural supplement to improve your thiamine status. TTFD, the main ingredient in Thiamax, has displayed the ability 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. It also includes a small amount of magnesium (as magnesium taurate), which plays an important role in supporting how your cells can use thiamine.

Thiamax – What makes it superior to other thiamine supplements?

Thiamax, a synthetic thiamine supplement, 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 deficiency.

Unlike ordinary forms of Vitamin B1 or thiamine supplements, 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, making it a useful way to supply thiamine to the body and improve thiamine status.

Also, what makes Thiamax superior to other Thiamine supplements is the fact that it’s the only form of TTFD in the world that doesn’t use any fillers or excipients.

Thiamax Dosage


How much Thiamine per day?

  • 1 capsule per day, with or without food.
  • Avoid coffee/tea consumption either 1 hour before or 2 hours after taking Thiamax.
  • Avoid taking it in the afternoon or evening, as it may interfere with your sleep cycle.
  • It should be taken alongside 200-400 mg of magnesium & a high quality B-complex.

For first time users:

  • Start with ½  or ¼  of a capsule per day by emptying the capsule contents into a small glass of water.
  • Increase the thiamine dosage every 3 or 4 days until you reach 1 full capsule per day.

Before you start taking Thiamax

In some individuals, thiamine supplements like Thiamax can induce a temporary worsening of certain symptoms such as fatigue, brain-fog, and digestive bloating or gas. These side effects usually last for around one week, and are referred to as the “paradoxical reaction”.

    Shipped fast. Very potent. I started with Benfotiamine by a brand that Amazon carries. Worked my way up to 1g a day. Saw noteworthy results but progress plateaued. Did a YouTube search and stumbled across Elliot Overton’s videos. Started on Thiamega with drastic improvements then eventually jumped up dosage even higher to Thiamax. Symptoms were POTS symptoms/CFS, Long Covid (but battled for decades with symptoms previous to virus), Celiac, Hypoxic/Tachycardic episode, crashing after any carb consumption, heat/cold /exercise intolerance, orthostatic hypotension. Completely changed my life. I actually have a life now!

    I’ve been taking 3 tablets a day of this product for about 2 months and don’t notice any difference. There is a protocol for how to take this but there is a charge of about $50. Why wouldn’t the protocol just be provided courtesy when you purchase the product? Seems a bit grifty of a way to operate. Before purchasing this product I reached out to EO Nutrition twice via email to request a paid appointment. I received no response. All in all I’m disappointed with this site.

    I hope that Objective Nutrients will continue to make this product because I will be taking this for life. I found out that I am thiamine deficient and have been for most of my life. Thiamax gives me relief of the symptoms.

    This is an amazing product. My suffering from low energy and leg muscle fatigue, was quickly relieved upon the start of this vitamin brand. I had tried other brands with no noticable improvement. I recommended this to several friends, who also noticed improved energy.
