Ashwagandha has become one of the most popular herbs for stress, sleep and anxiety support. But if you're breastfeeding, you may be wondering whether it's safe to take.
The short answer from most trusted sources — including herbalists, lactation consultants and medical organisations — is:
No. Ashwagandha is generally not recommended while breastfeeding.
This isn’t because ashwagandha is “dangerous”, but because there isn’t enough high-quality research proving it’s safe for infants — and herbs with hormonal or adaptogenic effects are usually avoided during lactation.
This guide explains why, what the research says, potential concerns, and safer alternatives for new mums.
Why experts say to avoid ashwagandha while breastfeeding
There are three main reasons most professionals advise caution:
1. Limited research on infant safety
There are currently no high-quality clinical studies examining ashwagandha’s effects on breastfed infants.
2. Ashwagandha affects hormones
Ashwagandha interacts with the endocrine system — meaning it can influence stress hormones, thyroid activity and reproductive hormones.
Because infant hormonal systems are still developing, experts avoid herbs with endocrine effects during breastfeeding.
3. Potential for infant drowsiness
Ashwagandha has mild sedative properties. Some lactation specialists express concern it may cause excess drowsiness in infants via breast milk.
For these reasons, most healthcare providers recommend choosing alternatives that are proven safe for breastfeeding mums.
What the research currently says
Here’s the honest summary:
- No clinical trials on ashwagandha during breastfeeding
- No established safe dosing guidelines for lactation
- Traditional Ayurvedic texts suggest caution
- Modern herbal boards (e.g. AHPA, EMA) classify it as “insufficient data”
In other words: there’s not enough evidence to say it’s safe — which means most experts avoid it.
Potential effects on breastfed babies
These are theoretical concerns, not proven harms — but they are why ashwagandha is avoided:
- Possible increased sleepiness
- Unknown long-term hormonal effects
- Potential digestive upset (ashwagandha is a nightshade)
- Possible allergenic response
Again, none of this means ashwagandha is “dangerous”. It simply means experts avoid herbs without infant-safety data.
Safer natural alternatives for breastfeeding mums
If you're looking for gentle, safe support during breastfeeding, focus on evidence-backed, non-hormonal options that lactation counsellors typically approve.
1. Magnesium
Well-tolerated and widely used by breastfeeding mums. Supports sleep, relaxation and stress.
Option: A clean magnesium powder (consult your GP for appropriate dosing).
2. Chamomile tea
Gentle, soothing and commonly used during breastfeeding.
3. Lavender (aromatherapy)
Safe topically or diffused, and helpful for relaxation.
4. Mindfulness & breathwork
Fast-acting tools for easing postpartum overwhelm.
5. Omega-3 (fish oil)
Widely recommended during postpartum for mood and cognition.
Avoid: adaptogens like ashwagandha, rhodiola, ginseng or maca while breastfeeding unless directed by a specialist.
When is ashwagandha considered safe again?
Most experts say ashwagandha can be safely reintroduced once:
- you have fully weaned from breastfeeding, or
- you are no longer producing milk
If you're considering using ashwagandha soon after weaning, speak with a GP — especially if you take thyroid medication or antidepressants.
Frequently asked questions
Is ashwagandha safe while breastfeeding?
Most experts say no due to limited research and potential hormonal effects. Consult a GP before using any herbal supplement.
Can ashwagandha reduce milk supply?
There’s no strong evidence either way, but because ashwagandha affects hormones, many lactation consultants advise avoiding it.
Are any adaptogens safe while breastfeeding?
Most adaptogens lack research for breastfeeding safety. Chamomile and magnesium are typically safer options.
When can I take ashwagandha again?
Generally after fully weaning or once milk production has stopped.
Final thoughts
Ashwagandha is a powerful herb — but due to limited research, it’s usually avoided during breastfeeding. This doesn’t mean it’s harmful, just unproven.
In the meantime, gentle options like magnesium, chamomile, omega-3 and mindfulness techniques can offer safe, effective support until you’re ready to consider adaptogens again.
