## Overview

Myristica fragrans (nutmeg) contains myristicin, elemicin, and safrole as primary bioactive compounds, along with lignans such as meso-dihydroguaiaretic acid (MDGA) that drive its antioxidant and [anti-inflammatory](/ingredients/condition/inflammation) effects. These compounds modulate NF-κB signaling and inhibit [lipid peroxidation](/ingredients/condition/antioxidant), forming the pharmacological basis for its traditional uses in digestive and inflammatory conditions.

## Health Benefits

• [Antioxidant activity](/ingredients/condition/antioxidant) demonstrated in vitro through DPPH radical scavenging and ferrous ion chelation, outperforming synthetic antioxidants BHA/BHT (P<0.05) - preliminary evidence only
• Traditional carminative properties for digestive support - no clinical trials available
• [Anti-inflammatory](/ingredients/condition/inflammation) effects reported in traditional medicine systems - lacking human studies
• Antifungal activity mentioned in traditional use - no clinical validation found
• Potential narcotic/psychoactive effects at high doses due to myristicin and elemicin content - toxicological concern rather than benefit

## Mechanism of Action

Myristicin, the principal volatile phenylpropanoid in nutmeg essential oil, inhibits monoamine oxidase (MAO) activity and modulates serotonergic pathways, contributing to reported mood and [cognitive](/ingredients/condition/cognitive) effects. The lignan meso-dihydroguaiaretic acid (MDGA) suppresses NF-κB transcription factor activation, thereby reducing downstream [pro-inflammatory cytokine](/ingredients/condition/inflammation) production including TNF-α and IL-6. Trimyristin, the dominant fixed fat in nutmeg, and its polyphenolic fraction scavenge [free radical](/ingredients/condition/antioxidant)s via hydrogen atom transfer (HAT) and single electron transfer (SET) mechanisms, outperforming synthetic antioxidants BHA and BHT in DPPH and ferrous ion chelation assays.

## Clinical Summary

Current evidence for Myristica fragrans in humans is limited primarily to in vitro and animal models, with no large-scale randomized controlled trials completed as of 2024. In vitro studies demonstrate statistically significant DPPH radical scavenging activity superior to BHA and BHT (P<0.05), though these results cannot be directly extrapolated to clinical outcomes. Rodent studies using doses of 100–500 mg/kg body weight have shown [anti-inflammatory](/ingredients/condition/inflammation) and gastroprotective effects, but human dose equivalents and bioavailability remain poorly characterized. Traditional carminative and digestive applications lack formal clinical trial validation, placing the overall evidence quality at preliminary or observational levels.

## Nutritional Profile

Per 100g ground nutmeg (USDA approximate values): Energy ~525 kcal; Fat ~36g (saturated ~25.9g, predominantly trimyristin/myristic acid C14:0); Carbohydrates ~49g (dietary fiber ~20.8g); Protein ~5.8g; Water ~6.2g. Key minerals: Manganese ~2.9mg (126% DV), Copper ~1.03mg (114% DV), Magnesium ~183mg (46% DV), Phosphorus ~213mg (30% DV), Iron ~3.04mg (17% DV), Calcium ~184mg (18% DV), Zinc ~2.15mg (20% DV), Potassium ~350mg (10% DV). Vitamins: Folate ~76µg (19% DV), Vitamin B6 ~0.16mg, Thiamin ~0.35mg, Vitamin C ~3mg, Niacin ~1.3mg, Vitamin A ~102 IU. Principal bioactive compounds: Essential oil (5–15% of dried seed) containing myristicin (~4% of seed weight, a phenylpropanoid with reported psychoactive and hepatotoxic properties at high doses), elemicin (~1–2.5%), safrole (~0.3–1%), sabinene (~15–28% of essential oil), α-pinene (~10–15% of oil), β-pinene, terpinen-4-ol, and limonene. Lignans: macelignan, nectandrin B (~0.01–0.05% of seed dry weight, showing [anti-inflammatory](/ingredients/condition/inflammation) activity in preclinical models). Neolignans: dehydrodiisoeugenol, erythro-austrobailignan-6, meso-dihydroguaiaretic acid. Phenolic acids and flavonoids contribute to measured total phenolic content of ~29–48 mg GAE/g extract. Fixed oil (nutmeg butter, ~24–30% of seed) rich in trimyristin (>75% of lipid fraction), used industrially. Carotenoids present in trace amounts. Bioavailability notes: Myristicin and elemicin are lipophilic and readily absorbed via GI tract but undergo extensive hepatic [metabolism](/ingredients/condition/weight-management) (CYP-mediated O-demethylation); bioactive lignan absorption is moderate; the high fiber content (~21g/100g) is relevant per serving only in supplement-dose contexts since culinary use is typically ≤1–2g; mineral bioavailability (especially iron and calcium) may be modulated by phytate and fiber content. Typical culinary serving (~1g/pinch) provides negligible macronutrient contribution but trace amounts of manganese and essential oil volatiles.

## Dosage & Preparation

No clinically studied dosage ranges are available due to lack of human trials. Traditional culinary use is mentioned but not quantified. Essential oil yields 5-15% from seeds, with myristicin content ranging from 2.12-2.88% in dry weight. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Nutmeg is generally recognized as safe (GRAS) by the FDA as a culinary spice at typical dietary doses, but myristicin and elemicin exhibit psychoactive and potentially hepatotoxic properties at doses exceeding 5 grams (roughly 1–2 teaspoons of ground nutmeg), causing symptoms including hallucinations, tachycardia, nausea, and anticholinergic toxidrome. Nutmeg may potentiate MAO inhibitor (MAOI) drugs due to myristicin's MAO-inhibiting activity, and concurrent use with serotonergic medications risks [serotonin](/ingredients/condition/mood) syndrome. Safrole, a minor constituent, is classified as a possible carcinogen by the IARC, though dietary exposure from normal culinary use is considered negligible. Pregnant women should avoid supplemental or high-dose nutmeg, as myristicin has demonstrated uterotonic activity in animal models and has been associated with fetal toxicity in case reports.

## Scientific Research

The research dossier reveals a complete absence of human clinical trials, RCTs, or meta-analyses on Myristica fragrans seed in the scientific literature. All available evidence comes from in vitro [antioxidant](/ingredients/condition/antioxidant) assays and traditional use reports, with no PubMed PMIDs provided for human studies.

## Historical & Cultural Context

Nutmeg has been historically valued as both a spice and traditional medicine, used for aromatic, stimulant, narcotic, carminative, antifungal, antidysenteric, and [anti-inflammatory](/ingredients/condition/inflammation) purposes. Commercial and pharmacological focus has long centered on the dried seed kernel, though specific traditional medicine systems are not detailed in available research.

## Frequently Asked Questions

### What is the toxic dose of nutmeg and what symptoms does it cause?

Toxicity typically begins at ingestion of 5 grams or more of ground nutmeg (roughly 1–2 teaspoons), equating to approximately 1–3 mg/kg of myristicin. Symptoms appear within 1–6 hours and include hallucinations, severe nausea, tachycardia, dry mouth, and agitation—collectively resembling an anticholinergic toxidrome—and may persist for 24–72 hours.

### Does nutmeg interact with any medications?

Yes, myristicin in nutmeg inhibits monoamine oxidase (MAO), creating a clinically relevant interaction risk with prescribed MAOI antidepressants such as phenelzine or tranylcypromine, potentially causing hypertensive crisis or serotonin syndrome. Nutmeg may also enhance sedative effects of CNS depressants and has theoretical interactions with anticoagulants due to its phenylpropanoid content affecting platelet aggregation.

### What bioactive compounds in nutmeg are responsible for its antioxidant effects?

The primary antioxidant activity in Myristica fragrans is attributed to the lignan meso-dihydroguaiaretic acid (MDGA), phenolic compounds including isoeugenol and eugenol, and the polyphenolic fraction of its fixed oil (trimyristin). These compounds scavenge free radicals via hydrogen atom transfer (HAT) mechanisms, with DPPH inhibition IC50 values reported as lower than those of synthetic antioxidants BHA and BHT in comparative in vitro studies.

### Can nutmeg supplements help with digestion?

Nutmeg has centuries of documented use as a carminative—a substance that reduces intestinal gas and spasm—attributed to volatile oils including myristicin, sabinene, and α-pinene, which may relax smooth muscle in the gastrointestinal tract. However, no human clinical trials have validated these effects, and current support is entirely based on traditional ethnopharmacological use and limited animal studies using doses of 100–300 mg/kg body weight.

### Is nutmeg safe during pregnancy?

Nutmeg at normal culinary amounts (less than 1 gram) is generally considered safe during pregnancy, but supplemental or high doses should be strictly avoided. Myristicin has demonstrated uterotonic activity in animal models, and at least one case report has linked high-dose maternal nutmeg ingestion to neonatal tachycardia and poor fetal outcome, raising a credible safety concern that warrants precautionary avoidance of concentrated nutmeg supplements during pregnancy.

### What is Colonial Nutmeg and how does it differ from other nutmeg varieties?

Colonial Nutmeg refers to Myristica fragrans sourced from traditional spice-producing regions, particularly Indonesia and other colonial-era trading zones. This designation typically indicates nutmeg harvested from mature trees using traditional methods, which may influence its bioactive compound profile compared to nutmeg from other geographic regions or cultivation practices. The term 'Colonial' reflects its historical significance in the spice trade rather than indicating a distinct botanical subspecies.

### What forms of nutmeg supplementation exist, and which has the best absorption?

Nutmeg is available as whole seeds, ground powder, essential oils, standardized extracts, and capsules containing powdered nutmeg. Standardized extracts may offer more consistent bioavailability of active compounds like myristicin and elemicin compared to whole seed or powder forms, though human absorption studies are limited. Lipid-soluble compounds in nutmeg are better absorbed when consumed with dietary fat, making capsules with oil-based formulations potentially advantageous over dry powder alone.

### Is nutmeg supplementation appropriate for children and elderly populations?

While nutmeg is generally recognized as safe in culinary doses for all age groups, concentrated supplements require caution in children due to toxicity risks at higher doses and limited pediatric safety data. Elderly individuals may use nutmeg supplements cautiously, though age-related changes in metabolism warrant lower doses and consultation with a healthcare provider. No clinical trials have specifically established safe dosing protocols for nutmeg supplements in either pediatric or geriatric populations.
