Is it safe to mix prenatal vitamins, dha, a metal chelator, and probiotics?

Children & pregnant : women should not use chelation at any dose except for lead poisoning, & then only under the supervision of doctors. Ask your OB if a DHA supplement is right for you. See www.fda.gov/food/foodborneillnesscontaminants/metals/ucm393070.htm. All women age 15-45 need a daily folic acid intake of 0.4 mg/day to prevent Neural Tube Defects. 0.6-0.8 mg. is given in pregnancy. Probiotics are okay.
