# Vitis vinifera (Sauvignon Blanc) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/vitis-vinifera **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-31 **Evidence Score:** 2 / 10 **Category:** Other **Also Known As:** Sauvignon Blanc, Sauvignon Blanc grape, White Sauvignon, Sauvignon Blanc cultivar, Bordeaux white grape, Sauvignon Blanc berry ## Overview Vitis vinifera Sauvignon Blanc is a white wine grape containing phenolic acids like caftaric acid and flavanols including catechin and epicatechin. No clinical health benefits have been documented for this cultivar as a supplement, with research focusing primarily on wine chemistry and aroma profiles. ## Health Benefits • No clinical health benefits documented - research focuses solely on wine chemistry and aroma compounds • Contains phenolic acids like caftaric acid with potential [antioxidant](/ingredients/condition/antioxidant) properties (no human studies) • Contains flavanols including (+)-catechin and (-)-epicatechin (no clinical efficacy data) • Contains flavonols such as quercetin-3-O-glucoside (no biomedical studies available) • Wine form contains SO₂ with [antimicrobial](/ingredients/condition/immune-support) effects (no therapeutic studies) ## Mechanism of Action The phenolic acids in Sauvignon Blanc, particularly caftaric acid, theoretically provide antioxidant activity through [free radical scaveng](/ingredients/condition/antioxidant)ing mechanisms. Flavanols like (+)-catechin and (-)-epicatechin may modulate cellular oxidative stress pathways, though specific molecular targets remain unstudied in this cultivar. ## Clinical Summary No human clinical trials have evaluated Sauvignon Blanc grape extracts for health benefits. Research on this cultivar focuses exclusively on wine production, analyzing chemical composition and aroma compounds for oenological purposes. Unlike other grape varieties, Sauvignon Blanc lacks any documented therapeutic applications or supplement formulations. The absence of clinical data makes it impossible to determine effective dosages or health outcomes. ## Nutritional Profile Sauvignon Blanc grape (Vitis vinifera) nutritional composition per 100g fresh grape berry: Carbohydrates 17-18g (primarily glucose and fructose in roughly equal proportions ~8-9g each), Protein 0.6-0.7g, Fat 0.2g, Fiber 0.9g, Water ~81g. Calories approximately 69-72 kcal/100g. Micronutrients: Vitamin K ~14-22mcg/100g, Vitamin C ~3-4mg/100g (modest), Vitamin B6 ~0.09mg/100g, Potassium ~191mg/100g, Copper ~0.13mg/100g, Manganese ~0.07mg/100g. Bioactive compounds specific to Sauvignon Blanc variety: Phenolic acids including caftaric acid (caffeoyltartaric acid) at ~150-300mg/kg fresh weight, coutaric acid (p-coumaroyltartaric acid) ~50-100mg/kg; Flavanols: (+)-catechin ~20-50mg/kg, (-)-epicatechin ~10-30mg/kg; Flavonols: quercetin-3-O-glucoside ~5-15mg/kg, kaempferol glycosides ~2-8mg/kg; Stilbenes: trans-resveratrol in skin ~0.5-2mg/kg (concentrated in grape skin, minimal in pulp); Varietal thiols (aroma precursors): S-3-(hexan-1-ol)-L-cysteine (3-SH precursor) and S-3-(hexan-1-ol)-[glutathione](/ingredients/condition/detox) present at trace levels influencing sensory rather than nutritional profile; Tartaric acid ~6-8g/kg and malic acid ~2-4g/kg as dominant organic acids. Carotenoids including beta-carotene ~0.02-0.04mg/100g and lutein ~0.07mg/100g primarily in skin. Bioavailability notes: Phenolic compounds have limited bioavailability from whole grape matrix (~10-30% absorption); quercetin glycosides require gut microbial deglycosylation before absorption; resveratrol bioavailability highly variable (20-50% from grape skin); tartaric acid largely excreted unmetabolized. Most concentration data derived from wine chemistry studies; direct fresh Sauvignon Blanc berry nutritional studies are limited compared to table grape varieties. ## Dosage & Preparation No clinically studied dosage ranges are available, as no human trials on Sauvignon Blanc extracts, powders, or standardized forms have been conducted. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data for Sauvignon Blanc grape supplements is unavailable due to lack of human studies. Standard grape allergies may apply, with potential reactions including skin irritation or digestive upset. Drug interactions are unknown but theoretically possible given the presence of flavanols that may affect drug [metabolism](/ingredients/condition/weight-management). Pregnant and breastfeeding women should avoid due to insufficient safety data. ## Scientific Research No human clinical trials, RCTs, or meta-analyses specific to Vitis vinifera (Sauvignon Blanc) extracts or derivatives were identified. All available research focuses on chemical composition, aroma precursors, and wine properties rather than biomedical applications. ## Historical & Cultural Context No historical or traditional medicinal uses of Vitis vinifera (Sauvignon Blanc) are documented in available sources. Modern use is limited to wine production and chemical analysis. ## Synergistic Combinations Other Vitis vinifera polyphenols, quercetin, catechins, resveratrol, grape seed extract ## Frequently Asked Questions ### Does Sauvignon Blanc grape extract have proven health benefits? No clinical studies have documented health benefits for Sauvignon Blanc grape extract. Research on this cultivar focuses solely on wine chemistry and aroma compounds, not therapeutic applications. ### What antioxidant compounds are in Sauvignon Blanc grapes? Sauvignon Blanc contains phenolic acids like caftaric acid and flavanols including (+)-catechin and (-)-epicatechin. However, no human studies have confirmed antioxidant benefits from these compounds in this specific cultivar. ### Are Sauvignon Blanc grape supplements available commercially? Sauvignon Blanc-specific supplements are extremely rare in the market. Most grape supplements use varieties with established research like Pinot Noir or generic grape seed extracts rather than this wine-focused cultivar. ### How does Sauvignon Blanc compare to other grape supplements? Unlike red grape varieties with extensive health research, Sauvignon Blanc lacks clinical studies and established supplement applications. Other grapes like Pinot Noir have documented cardiovascular benefits while Sauvignon Blanc remains unstudied therapeutically. ### What is the recommended dosage for Sauvignon Blanc extract? No established dosage exists for Sauvignon Blanc extract since no clinical trials have been conducted. Without safety or efficacy data, appropriate dosing cannot be determined for this particular grape cultivar. ### Is Sauvignon Blanc grape extract safe to take with blood thinners or antiplatelet medications? Sauvignon Blanc grapes contain compounds like quercetin and catechin that may have mild antiplatelet properties, though no clinical evidence demonstrates significant interaction risk. If you take warfarin, aspirin, or other anticoagulants, consult your healthcare provider before adding Sauvignon Blanc supplements, as phenolic compounds could theoretically potentiate blood-thinning effects. No documented adverse interactions exist, but caution is warranted in individuals on prescription anticoagulation therapy. ### Can I get the same polyphenols from eating grapes or drinking wine instead of taking Sauvignon Blanc extract supplements? Whole Sauvignon Blanc grapes and wine naturally contain the phenolic acids, flavanols, and flavonols found in supplements, though bioavailability varies depending on processing and consumption method. Wine fermentation alters polyphenol profiles and introduces alcohol, while whole grapes retain intact skin compounds; extract supplements concentrate specific compounds but lack the whole-food matrix. Dietary sources provide polyphenols alongside fiber and other nutrients, whereas supplements offer standardized doses of isolated compounds. ### Who should avoid Sauvignon Blanc grape supplements—are there contraindications for specific populations? Sauvignon Blanc supplements lack clinical safety data in pregnant, nursing, or pediatric populations, so these groups should avoid supplementation until evidence emerges. Individuals with histamine sensitivity or mast cell activation disorders should exercise caution, as grapes are naturally high in histamine, particularly in extract form. Those allergic to grapes or with polyphenol sensitivity should avoid this supplement entirely. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
