Organic Green Tea Aqueous Extract
Also known as: Organic Green Tea Extract, Green Tea Aqueous Extract, Camellia sinensis extract, EGCG-rich extract, Camellia sinensis aqueous extract
Overview
Organic green tea aqueous extract is derived from carefully cultivated and processed leaves of the Camellia sinensis plant. Rich in polyphenols, particularly catechins with epigallocatechin gallate (EGCG) as the primary compound, this extract is celebrated for its powerful antioxidant properties. It has been linked to several health benefits, notably weight management, improved cardiovascular health, and potential anti-cancer effects. The available evidence, drawn from systematic reviews and meta-analyses, demonstrates that when consumed appropriately, green tea extracts can enhance overall health outcomes, although variations in sample size and methodologies affect some findings. As a complement to a health-focused lifestyle, organic green tea aqueous extract provides significant opportunities for positive health impacts.
Benefits
1. **Weight Loss**: Systematic reviews indicate an average weight reduction of 1.31 kg over 12 weeks with green tea extract usage (Hartley et al., 2013). 2. **Cardiovascular Health**: Regular intake correlates with a 16% reduction in cardiovascular mortality risk (Kuriyama et al., 2006). 3. **Antioxidant Activity**: This extract has proven notable antioxidant capacity, lowering oxidative stress markers (Rowe et al., 2007). 4. **Potential Anti-Cancer Properties**: Research shows beneficial effects against various cancers, particularly highlighting prostate cancer (Bettuzzi et al., 2006), alongside advantages for athletic performance and recovery (Jówko et al., 2018). These findings substantiate green tea's integral role in promoting healthful practices.
How it works
The primary mechanism of action for green tea extract lies in its antioxidant properties, chiefly attributed to EGCG. This compound inhibits oxidative stress and inflammation through the suppression of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and stimulation of AMP-activated protein kinase (AMPK), both crucial in regulating inflammation and enhancing metabolism. Additionally, the extract contributes positively to lipid profiles and blood pressure, thereby supporting cardiovascular health, with its efficacy potentially improved by specific formulations that enhance bioavailability post-consumption.
Side effects
Organic green tea extract is generally safe when taken in moderate doses. Mild side effects, affecting over 5% of users, commonly include gastrointestinal issues such as nausea, diarrhea, and upset stomach. Uncommon side effects, seen in 1-5% of users, may include headaches and dizziness, while rare adverse effects occur in less than 1% of users, potentially manifesting as allergic reactions or liver toxicity. Individuals on anticoagulant therapy should exercise caution as the extract may interact with vitamin K. Pregnant or breastfeeding women should approach with care and consult healthcare professionals due to limited safety data. Additionally, those with liver diseases should be mindful of possible toxicity risks.
Dosage
The effective dosage of green tea extract usually ranges from 250 to 500 mg daily, ensuring that at least 25% of the content is EGCG. The optimal intake for most adults falls within 500-1000 mg daily, while a consensus indicates that a maximum safe dosage of 1200 mg is advisable. To enhance bioavailability, it's recommended to take green tea extract with meals. Aqueous extracts tend to provide superior absorption, and combining them with vitamin C or similar antioxidants can potentially maximize their effectiveness, although such co-factors aren't strictly necessary. A well-balanced diet is also advisable to support overall health.
