# Methyl Cinnamate **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/methyl-cinnamate **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-04-01 **Evidence Score:** 2 / 10 **Category:** Compound **Also Known As:** methyl (E)-cinnamate, methyl 3-phenylpropenoate, cinnamic acid methyl ester, methyl trans-cinnamate, methyl phenylpropenoate, strawberry aldehyde methyl ester ## Overview Methyl cinnamate is a naturally occurring ester of cinnamic acid found in essential oils of plants such as basil, cinnamon, and strawberries. It functions primarily as a fragrance and flavoring compound, with preclinical research suggesting interactions with olfactory receptors and weak [antimicrobial](/ingredients/condition/immune-support) activity, though no validated health benefits exist in human clinical trials. ## Health Benefits • No specific health benefits were identified in human clinical studies or RCTs. • The research dossier lacks evidence on methyl cinnamate’s health effects. • Its role is primarily as a flavoring agent due to its aromatic properties. • Further research is needed to establish any potential health benefits. • Current studies focus more on its chemical properties than biomedical applications. ## Mechanism of Action Methyl cinnamate is a phenylpropanoid ester formed from cinnamic acid and methanol, and preclinical data suggest it may weakly inhibit cyclooxygenase (COX-1 and COX-2) enzymes, potentially modulating prostaglandin synthesis in [inflammatory pathway](/ingredients/condition/inflammation)s. In vitro studies indicate it may disrupt microbial cell membrane integrity by interfering with lipid bilayer organization, contributing to its observed [antimicrobial](/ingredients/condition/immune-support) activity against strains such as Staphylococcus aureus. Additionally, it activates olfactory receptor neurons via transient receptor potential (TRP) channels, which underlies its established role as an aromatic flavoring agent. ## Clinical Summary No randomized controlled trials (RCTs) or human clinical studies have specifically investigated the health effects of methyl cinnamate as an isolated compound. Available evidence is limited to in vitro cell studies and animal models, which cannot be directly extrapolated to human physiology or therapeutic dosing. One in vitro study demonstrated antifungal activity against Candida albicans at concentrations of 500–1000 µg/mL, but these concentrations have not been validated in vivo. The overall evidence base is insufficient to support any health claim, and methyl cinnamate remains classified as a flavoring and fragrance ingredient rather than a therapeutic supplement. ## Nutritional Profile Methyl cinnamate (C₆H₅CH=CHCOOCH₃; molecular weight 162.19 g/mol) is a methyl ester of cinnamic acid. It is not a nutritional substance and does not contribute macronutrients (protein, fat, carbohydrates) or micronutrients (vitamins, minerals) in any meaningful dietary quantity. • Primary classification: Aromatic ester / flavoring compound. • Bioactive identity: It is itself a single bioactive compound rather than a source of multiple nutrients. • Naturally occurring concentrations: Found in trace amounts in essential oils of certain plants, including Alpinia galanga (galangal), some basil (Ocimum) chemotypes (up to ~50–70% of essential oil content), and Syzygium aromaticum (clove). Typical dietary exposure through spice use is estimated in the low microgram-to-low-milligram range per serving. • Chemical properties: White crystalline solid; melting point ~34–36 °C; poorly water-soluble (log P ~2.6); soluble in ethanol and organic solvents. • Caloric contribution: Negligible at flavoring-level doses (FEMA GRAS status, typical use levels ~1–50 ppm in food products). • Bioavailability notes: Absorbed via the gastrointestinal tract; undergoes hydrolysis by esterases to yield cinnamic acid and methanol. Cinnamic acid is further metabolized via β-oxidation to benzoic acid, which is conjugated with glycine to form hippuric acid and excreted renally. Oral bioavailability of the parent ester is limited due to rapid first-pass hydrolysis. • Related bioactive metabolite: Cinnamic acid (the hydrolysis product) has been studied for [antioxidant](/ingredients/condition/antioxidant), [anti-inflammatory](/ingredients/condition/inflammation), and [antimicrobial](/ingredients/condition/immune-support) properties, but these effects are attributed to the metabolite rather than methyl cinnamate itself. • No vitamins, minerals, fiber, or protein content. • No established Recommended Daily Intake or Adequate Intake values exist. • ADI (Acceptable Daily Intake): Not formally established by JECFA as a standalone value, but considered safe at current levels of use as a flavoring agent (FDA GRAS, FEMA No. 2698). ## Dosage & Preparation No clinically studied dosage ranges or forms are available, as no human studies have been conducted. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Methyl cinnamate is Generally Recognized As Safe (GRAS) by the FDA when used as a flavoring agent at low concentrations typical in food applications. Topical application in cosmetics and fragrances has been associated with contact dermatitis and skin sensitization in susceptible individuals, and it is monitored by the International Fragrance Association (IFRA). No clinically documented drug-drug interactions have been established, though theoretical CYP450 enzyme interactions cannot be excluded given its structural similarity to other cinnamate derivatives. Safety data during pregnancy and lactation are absent, and supplemental use beyond food-level exposure is not recommended without further research. ## Scientific Research There are no known human clinical trials, RCTs, or meta-analyses involving methyl cinnamate. Available research primarily discusses its chemical and flavor properties without PubMed PMIDs related to biomedical applications. ## Historical & Cultural Context There is no documented historical or traditional medicinal use of methyl cinnamate. It is known primarily as a natural component in plant essential oils and as a flavoring agent. ## Synergistic Combinations basil oil, galangal extract, bay leaf oil ## Frequently Asked Questions ### What is methyl cinnamate used for? Methyl cinnamate is used primarily as a flavoring and fragrance ingredient in foods, cosmetics, and perfumes, where it contributes a sweet, balsamic, strawberry-like aroma. It occurs naturally in essential oils of basil (Ocimum basilicum), cinnamon, and various fruits. Its use as a dietary supplement or therapeutic agent is not established due to a lack of human clinical data. ### Does methyl cinnamate have any proven health benefits? No human clinical trials or RCTs have demonstrated health benefits from methyl cinnamate supplementation. Preclinical in vitro studies suggest potential antimicrobial and weak anti-inflammatory activity via COX enzyme inhibition, but these findings have not been replicated in human subjects. Current scientific consensus supports its role exclusively as a flavoring compound, not a health supplement. ### Is methyl cinnamate the same as cinnamic acid? Methyl cinnamate and cinnamic acid are related but distinct compounds; methyl cinnamate is the methyl ester of cinnamic acid, formed by esterification of the carboxylic acid group with methanol. Cinnamic acid is the parent phenylpropanoid with its own documented bioactivity, including more extensive research on antioxidant and anti-inflammatory properties. The ester form, methyl cinnamate, has a lower polarity and different bioavailability profile compared to cinnamic acid. ### Can methyl cinnamate cause skin allergies? Yes, methyl cinnamate has been identified as a potential skin sensitizer, particularly in cosmetic and fragrance applications, and can cause allergic contact dermatitis in sensitive individuals. The International Fragrance Association (IFRA) sets usage concentration limits to minimize sensitization risk in leave-on products. Individuals with known fragrance allergies or cinnamon hypersensitivity should exercise caution when using products containing methyl cinnamate. ### What foods naturally contain methyl cinnamate? Methyl cinnamate is found naturally in strawberries, basil (Ocimum basilicum), cinnamon bark essential oil, and several other aromatic herbs and spices. In basil essential oil, methyl cinnamate can constitute up to 75% of the essential oil composition depending on the chemotype, particularly in tropical varieties. These food-level exposures are generally considered safe and contribute to the characteristic flavor profiles of these ingredients. ### Is methyl cinnamate safe for long-term consumption? Methyl cinnamate is generally recognized as safe (GRAS) by the FDA when used as a flavoring agent in food products at typical levels. However, long-term safety data from human studies is limited, and most safety assessments are based on its use as a food additive rather than as a concentrated supplement. Anyone considering regular supplemental use should consult a healthcare provider, as safety profiles for high-dose supplementation have not been extensively studied. ### What is the difference between methyl cinnamate and other cinnamate compounds? Methyl cinnamate is the methyl ester form of cinnamic acid, meaning it has a methyl group attached that makes it more volatile and aromatic than cinnamic acid itself. This structural difference gives methyl cinnamate its characteristic sweet, spicy smell, making it preferred for flavor applications rather than bioactive supplement uses. Other cinnamate compounds, such as sodium cinnamate, have different chemical structures and properties suited to different industrial purposes. ### Why is there limited research on methyl cinnamate's health effects compared to other cinnamates? Methyl cinnamate is primarily classified and used as a flavoring agent rather than a bioactive supplement ingredient, so research funding and clinical studies have focused more on its aromatic and chemical properties than potential health benefits. The scientific literature on cinnamates has concentrated more on cinnamic acid and its derivatives with established bioactive properties, leaving methyl cinnamate understudied from a nutraceutical perspective. As consumer interest in supplement ingredients grows, future research may provide more clarity on any potential health applications. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
