Why would zinc cause nausea?

[Guest guest]

Hi everyone...

I'm wondering why zinc would cause nausea?

Here's the situation:

My son (4 1/2 yo), who's been taking about the same dosage of zinc for

over a year has recently (for several months now) been complaining

about it. His speech isn't very good, so we thought he didn't like the

taste. Well, today I tried less than a teaspoon of it, and I felt

nauseous. We questioned my son, and he said that he felt sick when he

took it, so we're guessing he feels nauseous as well.

However, he just recently had a blood test, and his zinc levels are

still lower than normal, and lower than his copper levels. This has

improved from before, but not where they should be. So, I don't think

this nausea is from having too much zinc in his system...

Any ideas? He has a teaspoon of Kirkman zinc every night (20mg), and

he weighs about 40 lbs. I had less than a teaspoon tonight and I

weigh... umm... more than 40 lbs, and I felt sick anyway.

Thank you in advance,
