Life Extension Mega Benfotiamine, 250 mg, 120 Capsules

What the brand says

This formula contains both fat-soluble and water-soluble forms of B1 for better support of healthy metabolism as well as other B1 benefits, such as helping to keep your brain in top form and supporting nerve health. Benfotiamine, a fat-soluble form of vitamin B1 (thiamine), helps protect the body’s tissues against advanced glycation end (AGE) products and oxidative stress. Why do we include it? Benfotiamine is more bioavailable than water-soluble thiamine and can easily penetrate the inside of cells.
