Frequently Asked Questions
What is benfotiamine and is it better than regular thiamine?
What is benfotiamine and is it better than regular thiamine?
Benfotiamine is a fat-soluble derivative of thiamine with approximately 5 times higher bioavailability. It is particularly effective for diabetic neuropathy because it blocks advanced glycation end products (AGEs) that damage nerves and blood vessels. For general B1 needs, standard thiamine is fine, but benfotiamine is preferred for nerve-related conditions.
Who is at risk for thiamine deficiency?
Who is at risk for thiamine deficiency?
Chronic alcohol users are at highest risk, with up to 80% showing deficiency. Others at risk include diabetics (increased urinary excretion), elderly individuals, those taking loop diuretics, patients after bariatric surgery, and people with chronic vomiting or malabsorption conditions. Even subclinical deficiency can cause fatigue, irritability, and cognitive difficulties.
Can thiamine help with energy levels?
Can thiamine help with energy levels?
Thiamine is essential for converting carbohydrates into ATP energy. If you are deficient, supplementation will restore energy production. However, if your thiamine levels are already adequate, extra supplementation is unlikely to boost energy. High-dose B1 (50-100 mg) is included in many B-complex formulas marketed for energy, though benefits primarily occur in those with suboptimal status.
