This combination may serve to enhance brain function and support cognition, along with promoting healthy energy metabolism.

This high dose thiamine supplement  is free from fillers and excipients, highly bioavailable and  capable of penetration into the brain and central nervous system. .


Thiamega Benefits


Benfotiamine, an S-acyl derivative of thiamine, is well known for its ability to improve blood sugar management and support peripheral nerve function.

Sulbutiamine contains two molecules of thiamine bound together by a disulfide bond.

TTFD or Thiamine Tetrahydrofurfuryl Disulfide contains one thiamine molecule bound with a sulfur-mercaptan group, which provides it with unique properties.

The molecular structure of these thiamine derivatives in Thiamega, allows them to pass through intestinal and cellular membranes without the requirement for a transport system. Once inside the cell, they deliver thiamine which can be activated and used as a cofactor in important biochemical processes.




Thiamega Dosage - How many capsules per day?

  • 1 capsule per day in the morning, with or without food
  • 5 capsules per day, spread across the day, is the maximum dosage for Thiamega
  • Avoid coffee/tea consumption either 1 hour before or 2 hours after taking Thiamega
  • Avoid taking in the afternoon/evening, as it may interfere with your sleep cycle

Before you start taking Thiamega

Thiamega contains high dosage of thiamine derivatives. This may cause temporary side effects like insomnia, anxiety, fatigue, brain fog, and trouble concentrating, especially in individuals who are not accustomed to high dosage.

If symptoms persist for more than a few weeks, discontinue immediately.

Thiamega may not be suitable for individuals with sensitivity to sulfur-containing compounds.

    No synthetic ingredients, no issues with bowel movements after taking them. Body seems to be accepting of the product. Been taking it for about 3 weeks now

    I have been taking Benfotiamine for over a year without much improvement. Also, started another brand of TTFD for sometime, but again, not much improvement. And now started this brand. I like that it is multiple strains, but as yet, I have not seen any significant improvement or noticed any boost from this brand. And how do I determine how much is too much? Using published guidelines I was hitting about 1000mg a day with typical other brand BENFOTIAMINE and now about 600mg a day, thiamega. I Still hoping to see greater improvement. Ideally, I would like to see a test to determine what my ideal amount per day should be. Until then, I will keep increasing.

    I am only worried that this supplement would get sold out and no stock status will be continued again. Except that, I am so satisfied with the medicine and your company
