Vitamin B1 and general health
When it comes to general health, Vitamin B1 is one of the most supporting nutrients to consider. Essential cofactor for glucose metabolism and energy production, particularly in nerve and muscle cells. Benfotiamine is a fat-soluble derivative with up to 5x higher bioavailability than standard thiamine, making it especially beneficial for nerve health. Standard thiamine absorption is limited by intestinal transporters, but benfotiamine bypasses this through lipophilic pathways.
Effective dosing
Most evidence supports 25–100 mg of vitamin b1 daily. B-complex supplements typically provide 25–100 mg. Products below this range may not deliver meaningful results.
