Taking dietary supplements during pregnancy is entirely possible but requires medical advice. Self-medication should be avoided in general and even more so during this period. Pregnancy can cause minor daily ailments and certain dietary supplements can help relieve them. But not just any! Anses (National Agency for Food, Environmental and Occupational Health Safety) has warned against multiplying sources of vitamins and minerals, in the absence of established needs. During pregnancy, it is customary to take prenatal vitamins or an iron-based dietary supplement, at the request of the doctor or midwife. For the rest, at the risk of repeating ourselves, dietary supplements, such as probiotics, are possible but only on medical advice!
