Is it safe to take creatine hydrochloride while nursing?

Uncertain: It is not known if taking taking creatine is safe while nursing. In reality, nobody knows for sure, because there are many different brands of this, with varying purities, different doses, etc... That means a woman is safest if she doesn't take supplements that she does not truly need (some supplements are needed, most are NOT needed). Creatine supplements are usually unnecessary.
