<<Disclaimer: Verify this information before applying it to your situation.>> My son has gone through every vitamin possible - all cause nausea or some kind of GI upset. Only one that works is New Chapter Organics Tiny Tabs Multi. They are a "whole food complex" so can even be take on an empty stomach without GI upset. The dose is 6 tiny tabs for an adult (based on 150 lbs) ... so I give my 8 yr old son (who is only 45 lbs) 2 of them. They are excellent. Good luck. * Please remember some posters may be WHEAT-FREE, but not GLUTEN-FREE * Archives are at: Http://Listserv.icors.org/SCRIPTS/WA-ICORS.EXE?LIST=CELIAC
