Rutin Plus (Rutin)

Rutin is a flavonoid glycoside composed of quercetin and rutinose that provides antioxidant protection through reactive oxygen species scavenging. This bioflavonoid shows potential for supporting circulatory health and may help manage diabetic complications through aldose reductase inhibition.

Origin & History

Rutin is a flavonol-type flavonoid (quercetin-3-rutinoside) with molecular formula C₂₇H₃₀O₁₆, naturally found in buckwheat, citrus fruits, and apples. It is typically extracted from plant sources like Sophora japonica seeds using ethanol or water extraction methods, and is synthesized in plants via the phenylpropanoid pathway involving glycosylation and rhamnosylation enzymatic modifications.

Historical & Cultural Context

The research dossier provides no information on traditional medicine use, historical context, or cultural applications of rutin in systems like Ayurveda or Traditional Chinese Medicine.

Health Benefits

• Antioxidant activity through reactive oxygen species (ROS) scavenging due to polyphenolic structure (mechanistic evidence only)
• Potential diabetic complication support via aldose reductase 2 (ALR2) inhibition shown in molecular docking studies (preclinical evidence)
• Possible circulatory support through semi-synthetic derivatives (hydroxyethylrutosides) though human trial data not provided
• May reduce cellular oxidative stress by halting oxidative chain reactions (in vitro evidence referenced)
• P-glycoprotein inhibition activity suggesting potential drug interaction effects (mechanistic data from DrugBank)

How It Works

Rutin exerts antioxidant effects through its polyphenolic structure, which neutralizes reactive oxygen species and reduces oxidative stress. The compound demonstrates potential aldose reductase 2 (ALR2) inhibition in molecular docking studies, which may help prevent diabetic complications by reducing polyol pathway activation. Rutin's quercetin component contributes to capillary strengthening and vascular protection.

Scientific Research

The research dossier lacks details on human randomized controlled trials or meta-analyses for Rutin Plus or rutin alone. Available citations reference mechanistic studies (PMID: 12865317 on hydroxylation pathways) and preclinical work rather than human trials with defined sample sizes or clinical outcomes.

Clinical Summary

Current evidence for rutin is primarily mechanistic and preclinical, with limited human clinical trials available. Molecular docking studies suggest aldose reductase inhibition properties, while in vitro studies confirm antioxidant activity through ROS scavenging mechanisms. Most research focuses on rutin's parent compound quercetin, which has shown benefits in cardiovascular health studies. Well-designed human trials specifically examining rutin supplementation are needed to establish clinical efficacy.

Nutritional Profile

Rutin (rutoside, quercetin-3-O-rutinoside) is a flavonoid glycoside composed of the flavonol quercetin attached to the disaccharide rutinose (rhamnose + glucose). It is not a macronutrient source and contributes negligible caloric value. As a concentrated supplement ingredient, Rutin Plus typically delivers rutin at standardized doses ranging from 250–500 mg per serving. Bioactive compound profile: Rutin itself constitutes the primary active constituent (typically ≥95% purity in standardized extracts); upon ingestion, intestinal and colonic microbiota cleave the rutinose moiety to release quercetin as the principal bioactive aglycone, alongside rhamnose and glucose. Rutin also contains characteristic polyphenolic hydroxyl groups (catechol moiety on the B-ring) responsible for metal chelation and ROS scavenging capacity. Vitamins and minerals: None intrinsic to the isolated ingredient. Fiber and protein: Not applicable for isolated rutin extract. Bioavailability notes: Rutin has relatively poor oral bioavailability (~20% or less) compared to quercetin aglycone, due to its glycosylated form requiring enzymatic hydrolysis by gut microflora (primarily in the colon) before absorption; this results in delayed but sustained plasma quercetin levels peaking at approximately 6–9 hours post-ingestion. Semi-synthetic hydroxyethylrutinoside derivatives (e.g., troxerutin) demonstrate improved water solubility and potentially enhanced bioavailability compared to native rutin. Food sources include buckwheat (~1,800 mg/100g dry weight), capers (~332 mg/100g), asparagus, and citrus peel, though supplement forms deliver concentrated standardized quantities not achievable through diet alone.

Preparation & Dosage

Safety & Interactions

Rutin is generally considered safe when consumed in typical dietary amounts or standard supplement doses. Potential side effects may include mild gastrointestinal upset, headache, or skin flushing in sensitive individuals. Rutin may enhance the effects of anticoagulant medications due to its potential impact on platelet function and should be used cautiously with blood thinners. Pregnant and breastfeeding women should consult healthcare providers before supplementation due to limited safety data.
