What are the benefits of Benfotiamine?
Benfotiamine may help to maintain optimal thiamine levels in the body, support the body’s natural process of converting carbohydrates into energy, promote healthy digestion of proteins and fats, and support the proper release of hydrochloric acid. By supporting cellular energy production, Benfotiamine may also help combat occasional fatigue associated with a sluggish metabolism.*

What is the recommended dose?
The recommended dose is two capsules twice daily, or as directed by your healthcare professional.

When should I take it?
Benfotiamine can be taken once in the morning and once in the evening, with or without food.

How long can I take Benfotiamine for?
Benfotiamine can be taken for one month to two years.

Can it be taken with thyroid medications?
Benfotiamine should be taken at least 30 to 60 minutes away from thyroid medications. Testing your thyroid hormone levels every 30-90 days to see if a medication adjustment is needed, is recommended.

Thiamine supplementation should be avoided by those with advanced cancers. As thiamine is necessary for cell replication, tumors may steal the body’s reserves of thiamine and use it to proliferate. Those with thiamine deficiency and cancer may benefit from working with an integrative cancer specialist, as some studies have found an inverse dose-response to thiamine in those with advanced tumors, where the effect changes as the dose increases.²
