No, you shouldn’t use CBD while pregnant, trying to conceive or breastfeeding. The FSA says CBD isn’t suitable for these groups, because there’s no safety data in human pregnancy. A 2023 study of human placentas found CBD crosses into the placenta and can reach the baby. We don’t recommend our products during pregnancy or breastfeeding.
Below: what the research shows, CBD when trying to conceive, morning sickness, skin products, breastfeeding, and safer alternatives for sleep, nausea and stress.
What UK advice says
| Source | Advice |
|---|---|
| FSA | CBD isn’t suitable during pregnancy or breastfeeding, or for men and women trying to conceive |
| NHS | Check with a GP, midwife or pharmacist before taking any supplement or medicine in pregnancy |
| Prescription CBD (Epidyolex) | Used in pregnancy only if the benefit to the mother clearly outweighs the risk, under specialist care |
| Evopure | We don’t recommend our products during pregnancy or breastfeeding |
What the research shows
- CBD reaches the placenta. A 2023 study using donated human placentas found CBD built up in placental tissue and passed slowly towards the baby’s side. The authors stressed this doesn’t mean it’s safe.
- Animal studies have raised concerns about effects on development and on the male reproductive system, mostly at high doses.
- No human safety studies exist for CBD supplements in pregnancy, so nobody can say what a safe amount would be.
- Product quality: some CBD products contain THC, which is linked with lower birth weight. See is CBD addictive? for more on THC contamination.
CBD when trying to conceive
The FSA advises both men and women trying for a baby not to take CBD. Animal studies suggest possible effects on sperm and male hormones, though human data is lacking. If you’re planning a pregnancy, it’s simplest to stop CBD and speak to your GP about folic acid and vitamin D. See vitamin D in winter.
CBD balms and skincare in pregnancy
Very little CBD from a balm or cream reaches the bloodstream, but there’s no safety research on topical CBD in pregnancy either, and many balms also contain essential oils. The cautious choice is to avoid CBD skin products too, or ask your midwife first. For aches, see the NHS advice below.
If you’ve already taken CBD
Try not to worry. Stop taking it, and mention it to your midwife or GP at your next appointment so they have the full picture. If the product may have contained THC, or you used it regularly, tell them that too.
Safer options for common pregnancy symptoms
| Symptom | What the NHS suggests |
|---|---|
| Morning sickness | Rest, small frequent meals, plain snacks, ginger; speak to a GP or midwife if you can’t keep food or fluids down, as anti-sickness medicines are available |
| Poor sleep | Sleep on your side with pillows for support, a regular routine, gentle exercise in the day |
| Stress and anxiety | Talk to your midwife; NHS talking therapies can be accessed during pregnancy |
| Back pain and aches | Good posture, a warm bath, gentle exercise such as swimming; paracetamol if needed, after checking with a pharmacist |
