I will have to look at John's supplements to see what kind and how much of the bio available Bs are in them. He's taking Thorne multi and I know they use bio available Bs in many of their mixes.

Part of John's problem is getting them all down at the recommended dosage. His Exjade puts his stomach on edge.

One question on the folate. Is the folate in uncooked food the bioavailable form? Or does folate from vegetables still need to be converted?

It's so interesting to see how the B vitamins are vital to many aspects of your health.

Thanks....M
