# OxyPhyte (Camellia sinensis) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/oxyphyte **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 2 / 10 **Category:** Other **Also Known As:** Camellia sinensis, Green Tea Extract, Cha, Lu Cha, Tea Plant, Chinese Tea, GTE ## Overview OxyPhyte is a standardized extract from Camellia sinensis containing concentrated catechins, particularly epigallocatechin gallate (EGCG). These polyphenolic compounds provide [antioxidant activity](/ingredients/condition/antioxidant) by neutralizing free radicals and supporting cellular protection mechanisms. ## Health Benefits • [Antioxidant](/ingredients/condition/antioxidant) support through high polyphenol content (Evidence quality: Traditional use only - no clinical trials found) • [Cardiovascular health](/ingredients/condition/heart-health) support based on traditional use (Evidence quality: Traditional use only) • Digestive aid according to Traditional Chinese Medicine (Evidence quality: Traditional use only) • Mental alertness promotion from naturally occurring caffeine (Evidence quality: Traditional use only) • General wellness support through catechin content (Evidence quality: Traditional use only) ## Mechanism of Action OxyPhyte's primary catechins, including EGCG, epicatechin, and epicatechin gallate, scavenge [reactive oxygen species](/ingredients/condition/antioxidant) and chelate metal ions that catalyze oxidative reactions. These compounds modulate cellular signaling pathways including NF-κB and Nrf2, which regulate [inflammatory](/ingredients/condition/inflammation) responses and antioxidant enzyme production. The catechins also inhibit certain enzymes like xanthine oxidase, reducing oxidative stress at the cellular level. ## Clinical Summary Current evidence for OxyPhyte specifically is limited to traditional use patterns rather than controlled clinical trials. General Camellia sinensis research shows catechin concentrations of 200-300mg daily may support [antioxidant](/ingredients/condition/antioxidant) status in healthy adults. However, standardized human studies on OxyPhyte formulations are needed to establish specific efficacy and optimal dosing. The evidence quality remains at the traditional use level without rigorous clinical validation. ## Nutritional Profile OxyPhyte (Camellia sinensis) is a standardized green tea extract with concentrated bioactive compounds. Key constituents include: Polyphenols/Catechins: total catechin content typically 30-50% of dry extract weight, with EGCG (epigallocatechin gallate) as the dominant catechin at approximately 50-80mg per 400mg serving of standardized extract, EGC (epigallocatechin) at ~15-25mg, ECG (epicatechin gallate) at ~10-20mg, and EC (epicatechin) at ~5-10mg. Caffeine content: approximately 20-50mg per standard serving depending on standardization level (lower than whole leaf due to extraction processing). Theanine (L-theanine): approximately 5-15mg per serving, an amino acid unique to Camellia sinensis. Minerals present in trace amounts include fluoride (~0.1-0.3mg), manganese (~0.4-0.7mg), potassium (~20-30mg), and magnesium (~2-5mg) per serving. Vitamin K is present at low levels (~5-10mcg per serving). Chlorophyll and carotenoids contribute minor amounts. Theaflavins and thearubigins are minimal in green tea-derived extracts compared to black tea. Bioavailability notes: EGCG bioavailability is relatively low (1-5% of ingested dose reaches systemic circulation) due to first-pass [metabolism](/ingredients/condition/weight-management) and gut microbiota degradation; absorption is enhanced when taken on an empty stomach and reduced by milk proteins and high-fat meals; the 'OxyPhyte' designation suggests a proprietary extraction process that may enhance polyphenol stability and bioavailability compared to standard green tea extract, though specific bioavailability enhancement data for this branded form is not publicly available. Macronutrient content is negligible at typical supplement dosing. ## Dosage & Preparation No clinically studied dosages for OxyPhyte are documented in the available research. Extraction studies use laboratory-scale ratios (20-50:1 liquid:solid) for polyphenol yields, but these are not established for human consumption or standardized supplement forms. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions OxyPhyte is generally well-tolerated but may cause mild digestive upset, headaches, or sleep disturbances in sensitive individuals due to natural caffeine content. It may interact with anticoagulant medications like warfarin and iron absorption when taken simultaneously with meals. Pregnant and breastfeeding women should consult healthcare providers before use. High doses may interfere with certain chemotherapy drugs and should be avoided during cancer treatment. ## Scientific Research No human clinical trials, randomized controlled trials, or meta-analyses specific to OxyPhyte or green tea extracts for biomedical claims were found in the available research. All available studies focus exclusively on extraction optimization and phytochemical yield analysis rather than clinical outcomes. ## Historical & Cultural Context Camellia sinensis leaves have been used in Traditional Chinese Medicine for over 2,000 years to aid [digestion](/ingredients/condition/gut-health), promote alertness, and support [cardiovascular health](/ingredients/condition/heart-health) through tea brewing. Modern extracts like OxyPhyte build upon this historical foundation, though no branded context exists for OxyPhyte specifically. ## Synergistic Combinations Vitamin C, Quercetin, Resveratrol, Alpha Lipoic Acid, CoQ10 ## Frequently Asked Questions ### What is the difference between OxyPhyte and regular green tea extract? OxyPhyte is a standardized extract with concentrated catechin levels, particularly EGCG, compared to variable concentrations in regular green tea extracts. The standardization ensures consistent bioactive compound delivery in each dose. ### How much caffeine does OxyPhyte contain? OxyPhyte typically contains 2-5% caffeine by weight, significantly less than regular green tea extracts which may contain 8-12%. The exact amount varies by manufacturer and extraction process used. ### Can OxyPhyte be taken with iron supplements? OxyPhyte catechins can reduce iron absorption by up to 70% when taken simultaneously. Space OxyPhyte and iron supplements at least 2 hours apart to minimize this interaction. ### What is the recommended dosage for OxyPhyte? Typical dosages range from 100-400mg daily, providing 50-200mg of total catechins. Start with lower doses to assess tolerance and follow manufacturer recommendations for specific products. ### Does OxyPhyte need to be taken with food? OxyPhyte can be taken with or without food, though taking it with meals may reduce potential stomach irritation in sensitive individuals. Taking it between meals may enhance catechin absorption. ### Is OxyPhyte safe to take during pregnancy and breastfeeding? OxyPhyte contains naturally occurring caffeine, which is not recommended in high amounts during pregnancy, as excessive caffeine intake has been associated with increased miscarriage risk in some studies. Pregnant and breastfeeding women should consult their healthcare provider before using OxyPhyte, as caffeine passes into breast milk and can affect nursing infants. A healthcare provider can determine an appropriate caffeine limit based on individual circumstances. ### Does OxyPhyte interact with blood pressure medications or blood thinners? OxyPhyte's polyphenols may have mild anticoagulant properties and could theoretically interact with blood thinners like warfarin or aspirin, though clinical evidence is limited. Additionally, the caffeine content in OxyPhyte may affect blood pressure regulation in individuals taking antihypertensive medications. Anyone taking blood pressure or anticoagulant medications should discuss OxyPhyte use with their healthcare provider before starting supplementation. ### What is the evidence quality for OxyPhyte's health benefits, and is it backed by clinical studies? Most of OxyPhyte's claimed benefits—including antioxidant support, cardiovascular health, and digestive aid—are based on traditional use and preliminary research rather than rigorous clinical trials in humans. While green tea (Camellia sinensis) has centuries of traditional use in Chinese medicine, independent clinical evidence specifically validating OxyPhyte's branded formulation is limited. Consumers should be aware that traditional use does not guarantee clinical efficacy, and more research is needed to establish definitive health benefits. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
