Because of the anti-parasitic qualities of the herbs in Body Balance capsules, this supplement is not recommended during the first trimester of pregnancy, and should be used with caution later. Any medication or herbal formula that reaches your bloodstream will reach your baby. Weigh carefully your discomfort against releasing yeast, bad bacteria and virus into your bloodstream and into your milk. The ideal time for a Reboot is when you are neither pregnant nor lactating. Supplements that are both safe and beneficial during pregnancy are Exodus GI Sponge, Glutamine, and Probiotic Blend.
