Nutmeg: Uses, Benefits, Dosage & Safety
Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Nutmeg is a warming spice with traditional digestive and sleep uses — but in larger-than-culinary amounts it is genuinely toxic and even hallucinogenic.
What is Nutmeg?
Nutmeg (Myristica fragrans) is the seed of a tropical tree, used as a spice and in traditional medicine for digestion and sleep. It contains the compound myristicin.
What Nutmeg is commonly used for
In supplements, Nutmeg is most often included for gut & digestive health, nerve health support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Nutmeg works
Nutmeg's volatile oils, including myristicin, have mild digestive and sedative effects in small amounts, but at higher doses myristicin is psychoactive and toxic.
What the evidence says
Here's an honest snapshot of what published research suggests about Nutmeg — including where the evidence is limited.
- Beyond culinary use, clinical evidence for nutmeg supplements is minimal, and the safety risks of higher doses outweigh unproven benefits.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Nutmeg rather than relying on marketing claims.
Typical dosage used in studies
Culinary amounts (a pinch) are safe and flavourful; there is no established 'therapeutic' supplement dose, and larger amounts are dangerous. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
As little as one to two teaspoons of nutmeg can cause nausea, hallucinations, rapid heartbeat and serious toxicity. Use only culinary amounts, and avoid concentrated nutmeg in pregnancy. As with any supplement, it's sensible to introduce Nutmeg on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Nutmeg
Medication & safety check
Herbs interact with prescription medicines more often than people expect — affecting drug levels, bleeding, blood pressure, blood sugar or sedation — and Nutmeg is no exception. If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Nutmeg is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Nutmeg with your doctor or pharmacist first.
