Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Nutmeg has none that clears that bar.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
20 pairings are live across the library today. Checked 20 July 2026.
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
Nutmeg seed is roughly a quarter to a half fixed oil, mostly trimyristin, with the volatile phenylpropanoids dissolved in it. These compounds partition into lipid rather than water, so oil-based formats disperse them and aqueous ones do not. This is solubility behaviour, and it also means an oil format carries a heavier constituent load per unit weight than a ground spice does.
Nutmeg volatile oil constituents show sedative activity in animal models, and valerian is used specifically for that property. Combining them adds to the same effect rather than acting independently. Anyone driving or operating machinery should count both, and the combination is not something to increase casually.
Nutmeg has a long folk history as an evening spice for restlessness, and melatonin is the standard signalling agent for sleep timing. The mechanisms differ but the observable drowsiness stacks. There is no controlled work on the pair, so this is a caution rather than a recommendation.
Both appear in traditional calming preparations and both contribute lipophilic terpenoid and phenylpropanoid chemistry. The additive drowsiness is the practical point. Blend formulators should sum the sedative-leaning components rather than counting each in isolation.
Nutmeg, cinnamon and clove have been combined in the same preparations for centuries because their aromatic profiles complement each other. Chemically they all sit in the phenylpropanoid family, differing in the ring substitution. The pairing is culinary and formulation convention, and no combined pharmacology has been demonstrated.
Both are warming aromatic spices used around meals across several traditions. Ginger carries far more human data for digestive comfort than nutmeg does. In a blend, ginger is generally doing the documented work and nutmeg is contributing aroma and tradition.
The seed's fat fraction and its volatile oil both oxidise, producing rancid off-notes and loss of the aromatic constituents. Tocopherol is the standard chain-breaking antioxidant used to slow this in oleoresins and oil-filled capsules. It protects the material rather than adding any activity of its own.
Oil-filled softgels that carry one lipophilic ingredient will carry the other, and both need the same antioxidant protection in the fill. This is a manufacturing overlap and not a pharmacological relationship. Recorded so formulators do not read it as more than that.
Myristicin has been reported to inhibit monoamine oxidase in laboratory assays, and 5-HTP raises serotonin synthesis. Combining an agent that increases serotonin production with one that may slow its breakdown is a recognised class of concern, even where the in vivo relevance of the enzyme finding is unclear. Flagged as an interaction to avoid rather than a pairing to build on.
Nothing specific on file for Nutmeg. Match the label to the daily amount above, and tell your doctor what you take.

Read this carefully. These are 106 voluntary, unverified reactions reported to the FDA (openFDA). The number mostly reflects how popular Nutmeg is, not how risky it is. A report is not proof Nutmeg caused anything. It is a signal of what to watch for, nothing more.
