# Furosin **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/furosin **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 4 / 10 **Category:** Compound **Also Known As:** C27H22O19, Polyphenolic glucoside, Benzoxocin glycoside, Furosin compound, Beta-D-glucopyranose derivative ## Overview Furosin is a furanoflavonoid glycoside belonging to the flavonoid class of polyphenolic compounds, structurally characterized by a furan ring fused to the flavonoid backbone. Current scientific literature contains no human clinical trials or documented pharmacological data establishing any therapeutic mechanism or health application for this compound. ## Health Benefits • No clinically proven health benefits - no human trials exist • No documented effects on any health conditions - absence of clinical evidence • No verified therapeutic properties - no pharmacological trial data available • No established biomedical applications - no studies identified in PubMed • No confirmed physiological effects - no research on efficacy or outcomes ## Mechanism of Action Furosin's precise molecular mechanism of action has not been established in peer-reviewed pharmacological literature. As a furanoflavonoid glycoside, it is structurally hypothesized to share partial characteristics with related compounds such as psoralen and isopsoralen, which interact with cytochrome P450 enzymes and DNA photoadducts, but no receptor-binding, enzyme-inhibition, or signaling pathway data specific to furosin has been published. Any attribution of mechanisms involving [NF-κB](/ingredients/condition/inflammation) modulation, [antioxidant](/ingredients/condition/antioxidant) enzyme upregulation, or receptor agonism would be speculative in the absence of in vitro, in vivo, or clinical trial data. ## Clinical Summary As of the available scientific record, no human clinical trials, randomized controlled studies, observational cohort studies, or case reports have been published evaluating furosin in any therapeutic context. A search of PubMed and major biomedical databases yields no identified studies with quantified outcomes, sample sizes, or dosing protocols for this compound. No in vitro cell-culture studies or animal model experiments with documented endpoints have been attributed specifically to furosin in indexed literature. The current evidence base does not support any efficacy claims, and this compound remains scientifically uncharacterized at the clinical level. ## Nutritional Profile Furosin is a compound (also referred to as furosine, epsilon-N-(2-furoylmethyl)-L-lysine) formed as a Maillard reaction intermediate during the acid hydrolysis of Amadori compounds (specifically fructoselysine derived from the reaction between reducing sugars and the epsilon-amino group of lysine residues in proteins). It is not a nutrient or food ingredient itself, but rather an analytical marker compound. Key details: • It is a modified amino acid derivative with a molecular formula of C₁₂H₁₈N₂O₄ (MW ~254.28 g/mol). • It contains a furan ring conjugated to a lysine backbone via a methyl-carbonyl linkage. • No macronutrient value (not a source of carbohydrates, fats, or usable protein). • No micronutrient content (no vitamins or minerals). • No bioactive compounds of nutritional relevance at physiological concentrations. • Furosin/furosine is detected in heat-processed foods (e.g., UHT milk, dried milk powder, baked goods, roasted coffee) at levels typically ranging from ~1–300 mg/100 g protein depending on the severity of thermal processing. • Its presence is used as an indicator of lysine blockage (loss of bioavailable lysine), meaning higher furosine levels in a food correlate with reduced nutritional quality of the protein due to Maillard-induced lysine damage. • Bioavailability: Furosin itself is not intentionally consumed for nutritional benefit; it is largely excreted in urine and serves as an indirect biomarker of dietary exposure to early Maillard reaction products. It has no established absorption, distribution, or metabolic pathway associated with nutritional function. • No established Dietary Reference Intake, Recommended Daily Allowance, or tolerable upper intake level exists for this compound. ## Dosage & Preparation No clinically studied dosage ranges, forms, or standardization details are available as no human studies exist. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions No safety profile, toxicology data, or adverse event reporting exists for furosin in humans or animal models based on available indexed literature. Drug interaction potential, including effects on cytochrome P450 isoenzymes such as CYP3A4 or CYP1A2, has not been studied, making co-administration with pharmaceuticals an unknown risk. Pregnancy and lactation safety cannot be assessed due to the complete absence of reproductive toxicology data. Until peer-reviewed safety studies are conducted, consumption of furosin-containing supplements should be approached with caution and discussed with a qualified healthcare provider. ## Scientific Research No clinical evidence exists for furosin in human trials, RCTs, or meta-analyses. No PubMed PMIDs or studies on efficacy, sample sizes, or outcomes were identified in available sources. ## Historical & Cultural Context No traditional uses in medicine systems are recorded for furosin. Historical context and traditional applications remain unavailable in current sources. ## Synergistic Combinations None established - no synergistic compounds identified ## Frequently Asked Questions ### What is furosin and what class of compound does it belong to? Furosin is a furanoflavonoid glycoside, placing it within the broader flavonoid subclass of polyphenolic plant compounds. Its structure features a furan ring fused to a flavonoid core, distinguishing it from common flavonols like quercetin or kaempferol, though its natural plant sources and biosynthetic pathways have not been thoroughly documented in indexed scientific literature. ### Are there any clinical trials or human studies on furosin? No human clinical trials, observational studies, or case series evaluating furosin have been identified in PubMed or major biomedical databases. This means no dosing, efficacy endpoints, or safety outcomes have been established in human populations, and any health claims associated with furosin currently lack an evidence base. ### What are the potential health benefits of furosin? No clinically proven health benefits have been documented for furosin, as neither in vitro, animal, nor human trial data establishing therapeutic effects have been published. While structurally related furanoflavonoids have been investigated for antioxidant and anti-inflammatory properties in other research contexts, these findings cannot be extrapolated to furosin without compound-specific studies. ### Is furosin safe to take as a supplement? The safety of furosin as a supplement cannot be confirmed or denied due to a complete absence of toxicology, pharmacokinetics, or adverse event data in the scientific literature. No established tolerable upper intake level, LD50, or long-term safety profile exists for this compound, meaning potential risks, including drug interactions involving metabolic enzymes, remain entirely unknown. ### How is furosin different from other flavonoids like quercetin or rutin? Unlike quercetin, which has over 10,000 indexed studies examining its inhibition of enzymes like xanthine oxidase and modulation of SIRT1 pathways, or rutin, which has documented effects on capillary permeability and platelet aggregation, furosin has no comparable research record. The key structural difference is furosin's furanoflavonoid architecture, incorporating a furan oxygen-containing ring, but without experimental data this structural distinction has no confirmed functional significance. ### What food sources contain furosin naturally? Furosin is not commonly found in significant quantities in typical dietary sources. It is primarily studied as a laboratory-synthesized or derived compound rather than as a naturally abundant nutrient in foods. Current literature does not identify specific foods recognized as reliable dietary sources of furosin. ### Is furosin safe to take during pregnancy or while breastfeeding? No safety data exists for furosin use during pregnancy or breastfeeding, as there have been no human clinical trials or safety studies on this ingredient. Given the absence of any established safety profile, pregnant and nursing individuals should consult a healthcare provider before considering furosin supplementation. Without clinical evidence, its effects on fetal development or breast milk are unknown. ### Does furosin interact with common medications? No drug interaction studies have been conducted on furosin with pharmaceuticals or common medications. Because no human trials or pharmacokinetic research exists for this ingredient, potential interactions cannot be assessed or verified. Anyone taking prescription medications should consult their healthcare provider before adding furosin to their regimen, as its mechanism of action and metabolism remain undocumented. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
