Bobby,
This attitude is unbecoming.
Your research, one experiment with two animals, and no documentation as to the level of dietary B you provided,, is inadequate to base a scientific theory on. Plus, there is nothing at all that explains my question, which is WHY the two vitamins, dietary and body made, are different.
I feel when someone in the forums is searching for deeper answers and perhaps has a scientific curiosity, snapping at them the way you just did to me is not appropriate.
I do not want to get into an argument, I want some answers to reasonable scientific questions. It is OK if you don't know, Bobby. But if you would provide pointers to someone who does, I'd appreciate it. I plan to investigate Dan's pointer to the chicken diets but as you pointed out, chickens are not lizards. If you have pointers, I'd appreciate them.
