Mushroom Coffee During Pregnancy: What's Known and Safer Options
In one line
Mushroom coffee during pregnancy comes down to missing data: there are no safety studies of lion's mane, chaga, cordyceps or reishi in pregnancy, so the conservative answer is to skip mushroom coffee while pregnant and use a low-caffeine regular coffee instead — the caffeine itself, at 30–60 mg a serving, is fine under 200 mg a day.

This page is general information, not medical advice. It has been reviewed for accuracy, but your situation is specific — check with your clinician before changing what you drink.
The caffeine question is easy
Guidelines commonly cited in obstetric care advise keeping caffeine under 200 mg per day. Mushroom coffee servings run 30–60 mg. On caffeine alone, one cup is fine.
The mushroom question has no data
None of the functional mushrooms used in coffee have been studied in pregnancy. Chaga adds a specific concern — high oxalate content — on top of the general unknown.
What to do instead
Drink a half-caf or decaf regular coffee. You keep the ritual and the low caffeine and drop the unstudied extracts. Revisit mushroom coffee after breastfeeding, and check the breastfeeding page when it's published.
Frequently asked questions
Is the caffeine in mushroom coffee safe during pregnancy?
Major guidelines advise staying under 200 mg of caffeine a day in pregnancy. A serving of mushroom coffee has 30–60 mg, so the caffeine alone is within that limit. The question is the mushrooms, not the coffee.
Are functional mushrooms safe in pregnancy?
Unknown. There are no controlled studies of lion's mane, chaga, cordyceps, reishi or turkey tail extracts in pregnant people. Absence of evidence isn't evidence of harm, but it's the reason most clinicians say to avoid them.
What can I drink instead?
A half-caf or decaf regular coffee gives you the ritual and the lower caffeine without the unstudied extracts. If you want the mushroom flavour, culinary mushrooms in food are a different, well-established matter.
