Is Probiotics safe in pregnancy?
Generally safe
Yes — probiotic foods and most supplements are safe.
What the evidence says
Probiotic foods (yoghurt, kefir made from pasteurised milk, sauerkraut, kimchi) are safe in pregnancy. Probiotic supplements with well-studied strains (Lactobacillus, Bifidobacterium) are also considered safe. If you have a weakened immune system, discuss with your GP first.
Why this matters
Research on probiotics in pregnancy has generally shown safety, with some evidence of benefit for digestive comfort and possibly reduced pre-eclampsia risk.
