From the Research
Lion's mane mushroom (Hericium erinaceus) supplementation is not recommended during breastfeeding due to insufficient safety data. There is currently a lack of clinical research evaluating its safety for nursing mothers and potential effects on infants 1, 2, 3, 4, 5. While lion's mane has shown promising benefits for cognitive function, nerve health, and immune support in general populations, the bioactive compounds could potentially pass through breast milk to the infant with unknown consequences.
Key Considerations
- The most recent and highest quality study on the topic, published in 2023, investigated the acute and chronic effects of lion's mane mushroom supplementation on cognitive function, stress, and mood in young adults, but did not address breastfeeding or infant safety 5.
- A 2013 review highlighted the medicinal values of Hericium erinaceus, including its anti-cancer, immuno-modulating, and neuro-protective activities, but did not discuss its use during breastfeeding 3.
- A 2004 study emphasized the importance of physicians asking breastfeeding women about their use of herbal agents, including lion's mane, due to potential risks to the infant 2.
- A 2020 review discussed the anti-breast cancer activity of various mushrooms, including lion's mane, but did not address its safety during breastfeeding 4.
- A 2016 Cochrane review on multiple-micronutrient supplementation for breastfeeding women found no evidence to quantitatively assess the effectiveness of such supplementation, highlighting the need for high-quality studies on this topic 1.
Recommendations
- Nursing mothers should prioritize supplements and foods with established safety profiles during lactation.
- If interested in lion's mane for its cognitive or health benefits, it's best to wait until after the breastfeeding period has concluded or consult with a healthcare provider before use.
- Alternative evidence-based approaches for supporting cognitive and immune health during breastfeeding include:
- Adequate nutrition
- Omega-3 fatty acids from food sources
- Physician-approved prenatal vitamins
