(somewhat OT) question vitamin D and Zinc

[Guest guest]

HI

My son has had consistently low levels for vitamin D and zinc.

We did an RBC for the zinc a year ago and even though we supplement

it twice a day, its at about the same levels now, very low. Same with vitamin D.

We live in the northeast so I can sort of understand the D issue but

have been giving 500 iu ( was 1000 iu in winter ) He is 3 and 32 lbs.

He has been on all the recommended chelation supplements andeats great.

We own a shellfish grant and I know oysters are high in zinc. Are they safe? I

am nervous about mercury content in them.

Any suggestions or advice appreciated. Just want to get these levels up

without overdoing the supplements. I do give the zinc at bedtime on an empty

stomache and first thing in the morning.

Thanks
