Hi Pat, We receive your question often and you can find that answer just below in a response to the same concern. Here is a reposting:
The B vitamin levels in our B Strong are very comparable to other B complexes. We have more 5-MTHF and Methyl-B12 and niacinamide than most other brands of B complex brands. Those are the most expensive ingredients so that is important to remember. We also have 20 mg of benfotiamine (fat soluble form of B1 that is the most superior form of B1) in our B Strong and most other quality B complex do not contain any benfotiamine and just load up a higher dosage of thiamine HCL which is a cheaper ingredient and not as absorbable for effective as the benfotiamine. It is good to have a combination of the water soluble thiamine HCL and the fat soluble benfotiamine for optimal B1 support.
