Can your products be taken during pregnancy or lactation?
Integrated Health Products usually does not make recommendations concerning the use of products during pregnancy or lactation, with the exception of prenatal vitamins. Some products may have known contra-indications, while the effects of others may have not been fully studied. Talk to your doctor before taking supplements while pregnant or lactating.

Are your supplements okay to take with prescription medications?
It is always good to consult with a medical provider before starting any new supplement. Just because a supplement is not a prescription, does not mean it is safe.
