# Helicid (4-hydroxy-3-methoxybenzaldehyde-β-D-glucopyranoside) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/helicid **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-29 **Evidence Score:** 4 / 10 **Category:** Compound **Also Known As:** 4-hydroxy-3-methoxybenzaldehyde-β-D-glucopyranoside, Vanillin glucoside, Helicia nilagirica glycoside, HN-1 compound, Vanillic aldehyde β-D-glucopyranoside ## Overview Helicid (4-hydroxy-3-methoxybenzaldehyde-β-D-glucopyranoside) is a phenolic glycoside that may support [cognitive function](/ingredients/condition/cognitive) and mood through hippocampal neurogenesis. Preliminary animal studies suggest it activates the cAMP/PKA/CREB signaling pathway to enhance memory formation and reduce depressive symptoms. ## Health Benefits • May improve depressive symptoms in animal models through hippocampal neurogenesis and cAMP/PKA/CREB pathway activation (preliminary evidence from rat studies) • Potentially enhances [cognitive function](/ingredients/condition/cognitive) and spatial memory performance in stress models (based on Morris water maze testing in rats) • Could promote neuronal proliferation in hippocampal CA1 and dentate gyrus regions (demonstrated in preclinical models only) • May reduce stress-induced behavioral changes including improved sucrose preference and locomotor activity (shown in chronic unpredictable mild stress rat models) • Potentially protects against neuronal apoptosis by reducing cleaved caspase-3 levels (preliminary evidence from animal studies) ## Mechanism of Action Helicid activates the cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA)/cAMP response element-binding protein (CREB) signaling pathway in hippocampal neurons. This activation promotes brain-derived neurotrophic factor (BDNF) expression and stimulates neurogenesis in the dentate gyrus region. The compound's phenolic structure allows it to cross the blood-brain barrier and modulate [neurotransmitter](/ingredients/condition/cognitive) systems involved in memory consolidation and mood regulation. ## Clinical Summary Current evidence for helicid is limited to preclinical animal studies, primarily conducted in rat models. Morris water maze testing showed improved spatial [memory](/ingredients/condition/cognitive) performance and reduced escape latency times in stressed rats treated with helicid. Depression-related studies demonstrated increased hippocampal cell proliferation and improved behavioral outcomes in forced swim tests. No human clinical trials have been conducted to date, making the therapeutic relevance uncertain. ## Nutritional Profile Helicid (4-hydroxy-3-methoxybenzaldehyde-β-D-glucopyranoside) is a pure isolated phytochemical compound, not a food or nutritional source, and therefore does not possess a conventional nutritional profile with macronutrients, micronutrients, vitamins, minerals, fiber, or protein content. It is a phenolic glycoside with molecular formula C14H18O8 and molecular weight of 314.29 g/mol. Structurally, it consists of a vanillin (4-hydroxy-3-methoxybenzaldehyde) aglycone moiety linked via a β-glycosidic bond to a D-glucopyranose sugar unit. As a bioactive compound, it belongs to the phenylpropanoid-derived aldehyde glycoside class. It is naturally found in the bark of Helicia species (Proteaceae family) at concentrations typically ranging from 0.1–1.5% dry weight depending on plant part and extraction method. Bioavailability data in humans is limited; however, as a glycoside, it is presumed to undergo hydrolysis by intestinal β-glucosidases or colonic microbiota to release the aglycone vanillin, which may influence absorption kinetics. Studies in rodents typically employ doses of 10–80 mg/kg body weight administered orally or intraperitoneally. No caloric value, mineral content, or vitamin content is applicable to this isolated compound. ## Dosage & Preparation No human dosage data exists. Rat studies used oral doses of 8-32 mg/kg/day via gavage for 6 weeks, with 32 mg/kg showing significant effects. Research utilized purified compound (≥98% purity) rather than standardized extracts. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data for helicid supplementation in humans is currently unavailable due to lack of clinical trials. As a phenolic glycoside, it may theoretically interact with medications metabolized by cytochrome P450 enzymes, though specific interactions have not been documented. Pregnant and breastfeeding women should avoid helicid supplements due to insufficient safety data. Individuals taking antidepressant medications should consult healthcare providers before use due to potential additive effects on [neurotransmitter](/ingredients/condition/cognitive) pathways. ## Scientific Research Current evidence is limited to preclinical rat studies using chronic unpredictable mild stress (CUMS) models. One study (PMID: 31257291) examined 60 Sprague-Dawley rats over 12 weeks, administering helicid at 8-32 mg/kg orally for 6 weeks, demonstrating improved behavioral and [cognitive](/ingredients/condition/cognitive) outcomes. No human clinical trials, RCTs, or meta-analyses have been conducted. ## Historical & Cultural Context Helicid is derived from Helicia nilagirica seeds, a Chinese herb, though specific traditional medicine applications or historical usage patterns are not documented in available sources. Modern research focuses on the isolated compound's bioactive properties rather than traditional ethnopharmacological uses. ## Synergistic Combinations St. John's Wort, Rhodiola, Lion's Mane, Phosphatidylserine, Bacopa monnieri ## Frequently Asked Questions ### What is the optimal dosage of helicid for cognitive benefits? No established human dosage exists for helicid since all studies have been conducted in animals. Rat studies used doses ranging from 10-50 mg/kg body weight, but human equivalent doses cannot be safely extrapolated without clinical trials. ### How long does it take for helicid to show cognitive effects? Animal studies showed measurable improvements in spatial memory after 14-21 days of helicid treatment. However, human timeframes may differ significantly and remain unknown without clinical research. ### Can helicid be taken with antidepressant medications? The safety of combining helicid with antidepressants is unknown due to lack of human studies. Since helicid may affect similar brain pathways as antidepressants through cAMP/PKA/CREB signaling, medical supervision would be advisable. ### What foods naturally contain helicid? Helicid is found in certain traditional medicinal plants, particularly those used in Asian herbal medicine. However, specific food sources and their helicid concentrations have not been well-documented in scientific literature. ### Is helicid safe for long-term use? Long-term safety of helicid in humans is completely unknown since no chronic toxicity studies or extended human trials exist. Animal studies have not reported significant adverse effects, but this cannot predict human safety profiles. ### Is helicid safe for pregnant or breastfeeding women? Current safety data for helicid in pregnant and breastfeeding women is limited, with no established clinical trials in these populations. Animal studies have not specifically evaluated developmental or reproductive toxicity of helicid. It is advisable to consult with a healthcare provider before use during pregnancy or lactation, as the blood-brain barrier permeability and placental transfer characteristics of this compound remain understudied. ### What does the current clinical research evidence show about helicid's effectiveness in humans? Existing evidence for helicid in humans remains preliminary, as most supporting research consists of animal models in rodents using cognitive and depression-related assays. Clinical trials specifically evaluating helicid's efficacy and safety in human subjects have not yet been published in peer-reviewed literature. The mechanism of action through hippocampal neurogenesis and CREB pathway activation is promising but requires human clinical validation before definitive efficacy claims can be made. ### How does helicid compare to other plant-derived compounds targeting neurogenesis and mood? Helicid is a glucoside derivative found in certain plants and acts through distinct cAMP/PKA/CREB signaling, which differs mechanistically from some common nootropics and mood-supporting compounds like resveratrol or curcumin that operate through different pathways. Direct comparative efficacy studies between helicid and other neurogenic compounds in humans have not been conducted, making direct conclusions about relative effectiveness premature. Its specific targeting of hippocampal neurogenesis represents a potential differentiation point, though this has only been demonstrated in animal models. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
