I'm not an MD, but I do know that its not possible to draw so many conclusions from the scant information provided by the original poster. For example, see my posting on manganese which I've quoted an MD regarding vitamin B1 and manganese. This is only one potentially conflicting issue, and there are many possible. When you go to a Dr.'s office, you typically fill out a long form, in order that they may learn something about the patient's history. This information, you do not have. Moreover, even with such information, experienced professionals still are not always able to correct metabolic defects, or make accurate diagnoses in 100% of the cases. So, its a bit bombastic to conclude as you have, and to make any recommendations at all, in my opinion. Extending the concept given your lack of information about all the people in this forum whom you allege as having overloaded poorly functioning systems is also an over-reach, and an indefinite statement. Just exactly how "full" is this forum of such people ? Half way full ? 3/4 full ? Can you spot a person who is overloaded with a poorly functioning "system", just by one posting they write ?
Fortunately, people on here are aware that what other anonymous internet folk write does not constitute "medical advice" and is only opinion, which they are free to ignore.
Sometimes, issues such as these can be resolved by by the person supplying themselves with the one or two minerals or vitamins they are deficient in, and the trouble is in determining the deficiency. In more chronic cases, other complications have arisen, and the work becomes more involved.
I do not believe that given the original posting, that any conclusion can be drawn regarding the person's liver, and I don't think it helps anyone to imply that they are "stupid", its just not polite. It could be that most experienced practitioners might believe that your whole message is stupid, but I doubt any would ever write such a thing.
