Oxxynea (Mixed Fruit and Vegetable Extract)

Oxxynea is a standardized blend of 22 fruit and vegetable extracts delivering a broad spectrum of polyphenols, carotenoids, and glucosinolates. It works through triphasic absorption of polyphenolic metabolites to sustain antioxidant activity for up to 24 hours after a single dose.

Origin & History

Oxxynea is a branded polyphenol-rich extract developed by Fytexia, combining extracts from green olive, grape, pomegranate, green tea, grapefruit, bilberry, and citrus to mimic the polyphenol content of 5 servings of fresh produce daily. The extract is standardized to ≥51% total polyphenols (gallic acid equivalents) and contains over 100 compounds from five main polyphenol families.

Historical & Cultural Context

Oxxynea has no traditional or historical use context. It is a modern branded extract developed specifically to address nutritional gaps from low fruit and vegetable intake in contemporary diets, with no evidence of prior traditional applications in any medicine system.

Health Benefits

• Reduces cardiovascular risk markers - animal study showed 77% reduction in aortic fatty streak area and lowered plasma cholesterol (preliminary evidence from hamster model)
• Provides 24-hour antioxidant protection through triphasic absorption of polyphenolic metabolites (demonstrated in human pharmacokinetic study, n=10)
• Limits post-meal oxidative stress by reducing malondialdehyde production after high-fat/carb meals (mechanism-based evidence)
• Reduces cardiac oxidative stress - 45% reduction in superoxide anion and 59% reduction in NAD(P)H oxidase expression (preliminary evidence from animal model)
• Improves polyphenol bioavailability with reduced inter-individual variability compared to single-source extracts (human pharmacokinetic evidence, n=10)

How It Works

Oxxynea delivers polyphenols, carotenoids, and glucosinolates that are absorbed in three distinct phases, corresponding to digestion in the small intestine, colonic fermentation, and secondary metabolite release, sustaining elevation of plasma antioxidant capacity across a full day. These compounds upregulate endogenous antioxidant enzymes including superoxide dismutase and catalase while scavenging reactive oxygen species directly. Polyphenolic metabolites also inhibit LDL oxidation and modulate NF-κB-mediated inflammatory signaling, which contributes to its observed cardiovascular protective effects.

Scientific Research

Limited human research exists, with only one pharmacokinetic crossover trial (n=10) testing 450mg Oxxynea absorption over 24 hours. The primary evidence comes from a 12-week animal study (PMID: 17444653) in cholesterol-fed hamsters showing significant reductions in cardiovascular risk markers. No human RCTs on clinical outcomes or disease prevention have been published.

Clinical Summary

A preclinical study using a hamster atherosclerosis model demonstrated a 77% reduction in aortic fatty streak area and significant reductions in plasma total cholesterol following Oxxynea supplementation, though hamster models have limited direct translation to humans. A human pharmacokinetic study confirmed triphasic absorption of polyphenolic metabolites over 24 hours, providing mechanistic support for sustained antioxidant coverage with once-daily dosing. Human evidence remains preliminary, with no large-scale randomized controlled trials published to date confirming cardiovascular endpoints in human populations. Overall, the existing evidence is promising but insufficient to make definitive clinical claims without further Phase II or III human trials.

Nutritional Profile

Oxxynea is a concentrated mixed fruit and vegetable extract standardized to deliver a broad spectrum of polyphenolic compounds, designed to mimic the polyphenol intake equivalent of 5 servings of fruits and vegetables per day. Bioactive compounds include anthocyanins (from berry sources such as blackcurrant and blueberry), flavonols (quercetin, kaempferol), hydroxycinnamic acids (chlorogenic acid, caffeic acid), resveratrol (from grape sources), lycopene (from tomato), lutein and zeaxanthin (from green vegetable sources), and glucosinolate derivatives (from brassica sources). The extract is typically delivered at a dose of 450–500 mg per serving in commercial formulations. Macronutrient content is negligible at functional doses (minimal calories, fat, and protein). Micronutrient contribution is minor relative to whole food equivalents. Bioavailability is a key feature: human pharmacokinetic data (n=10) demonstrates triphasic absorption of polyphenolic metabolites over a 24-hour period, attributed to differential absorption kinetics — early-phase absorption of simple phenolics and flavonoids in the small intestine, mid-phase absorption of anthocyanin metabolites, and late-phase colonic fermentation-derived metabolites (e.g., phenylpropionic and phenylacetic acid derivatives), collectively sustaining plasma antioxidant activity throughout the day. Fiber content is minimal due to the extraction process. No significant vitamin or mineral concentrations are documented at standard doses.

Preparation & Dosage

Clinically studied dose: 450 mg/day (equivalent to polyphenols from 5 fruits/vegetables). Manufacturer recommends 90 mg/day minimum for general use. Available as powder extracts: Oxxynea-FP (fat-soluble) and Oxxynea-WS (water-soluble). Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Vitamin C, Vitamin E, Coenzyme Q10, Alpha-lipoic acid, Resveratrol

Safety & Interactions

Oxxynea is derived from food-based fruit and vegetable sources and is generally considered well-tolerated, with no serious adverse effects reported in available studies at standard supplemental doses. Because it contains polyphenols that may weakly inhibit cytochrome P450 enzymes (particularly CYP3A4 and CYP1A2), caution is warranted in individuals taking narrow-therapeutic-index drugs such as warfarin, cyclosporine, or certain statins. Pregnant and breastfeeding women should consult a healthcare provider before use, as safety data in these populations is absent. Individuals with known allergies to any of its 22 constituent fruits or vegetables should review the full ingredient list before supplementing.
