Supertea Xtreme Lipolytic Catalysis Complex
Also known as: Tea polyphenols (catechins), EGCG (Epigallocatechin gallate), Caffeine, Lipolytic agents, Green Tea Extract, Camellia sinensis extract, Epigallocatechin Gallate (EGCG) & Caffeine
Overview
Supertea Xtreme Lipolytic Catalysis Complex is a weight management supplement likely containing concentrated tea extracts, primarily green tea, rich in catechins like Epigallocatechin Gallate (EGCG) and caffeine. These components are known for their antioxidant and metabolic effects. The supplement is designed to support weight loss, enhance fat oxidation, and increase metabolic rate. It is often classified as a thermogenic or lipolytic complex. The key characteristics include antioxidant properties, thermogenic effects, and the potential to stimulate lipolysis (fat breakdown). Research on tea extracts and their components is extensive, with numerous randomized controlled trials (RCTs) and meta-analyses available, providing moderate to high-quality evidence, especially for green tea catechins and caffeine in fat oxidation and modest weight loss.
Benefits
Meta-analyses suggest that green tea catechins combined with caffeine can increase 24-hour energy expenditure by approximately 4-5% and enhance fat oxidation by about 16-17%. This translates to modest weight loss, with an average reduction of 1-3 kg over 12 weeks compared to placebo. The antioxidant effects may reduce oxidative stress markers, and potential improvements in lipid profiles and insulin sensitivity have been reported, though further confirmation is needed. Benefits are more pronounced in overweight or obese individuals and those with low habitual caffeine intake. While the weight loss effect is statistically significant, it is clinically modest, suggesting that tea extracts are best used as adjuncts to diet and exercise. Effects typically manifest within 8-12 weeks of consistent supplementation.
How it works
Catechins inhibit catechol-O-methyltransferase (COMT), prolonging norepinephrine activity, which stimulates thermogenesis and lipolysis. Caffeine acts as a central nervous system stimulant, increasing cyclic AMP and promoting fat breakdown. This enhances sympathetic nervous system activity, increases metabolic rate, and promotes fatty acid mobilization from adipose tissue. The known molecular targets include the COMT enzyme, adenosine receptors (caffeine), and beta-adrenergic receptors. Catechins have moderate bioavailability, while caffeine is well absorbed. Bioavailability can be influenced by food intake and the specific formulation of the supplement.
Side effects
Supertea Xtreme Lipolytic Catalysis Complex is generally safe when consumed within recommended doses, with adverse effects being rare and mild. Common side effects (occurring in >5% of users) include mild gastrointestinal discomfort, jitteriness, and insomnia, primarily due to the caffeine content. Uncommon side effects (1-5%) may include headache and increased heart rate. Rare side effects (<1%) include reports of liver toxicity with very high doses of green tea extracts. Potential drug interactions exist with stimulant drugs, anticoagulants (due to vitamin K in tea), and certain antidepressants. It is contraindicated for individuals with caffeine sensitivity, during pregnancy and breastfeeding, and in those with liver disease. Caution is advised for hypertensive patients and those with cardiovascular conditions.
Dosage
The minimum effective dose is approximately 270 mg of EGCG daily combined with 150 mg of caffeine. Optimal dosage ranges include 300-600 mg/day of EGCG and 100-200 mg/day of caffeine. The maximum safe dose is considered to be up to 800 mg EGCG/day, while caffeine intake should not exceed 400 mg/day from all sources. It is best taken in the morning or early afternoon to avoid sleep disturbances. Standardized extracts with known catechin and caffeine content are preferred. Taking the supplement with food may reduce absorption but can also mitigate gastrointestinal side effects. No specific cofactors are required, though hydration and a balanced diet can enhance the effects.
FAQs

Is it safe to take daily?
Yes, within recommended doses, but monitor for caffeine-related side effects such as jitteriness or insomnia.
When should I take it?
Morning or early afternoon is recommended to minimize potential sleep disruption from the caffeine.
How soon will I see results?
Typically, effects may be noticeable within 8-12 weeks of consistent supplementation and lifestyle modifications.
Does it work without diet/exercise?
The effects are likely limited without concurrent lifestyle modifications such as a balanced diet and regular physical activity.

- – Hursel et al. (2009) meta-analysis included 11 RCTs and showed that green tea catechins plus caffeine increased energy expenditure by ~4% and fat oxidation by ~16%, with modest weight loss (mean difference ~1.3 kg) over 12 weeks. The study noted limitations including heterogeneity in doses and populations, and the quality was rated moderate to high.
- – Jurgens et al. (2012) systematic review reviewed 15 RCTs, confirming small but significant weight loss effects of green tea extracts. The review found that effects were dose-dependent and more pronounced in overweight individuals, with a favorable safety profile and mild side effects.
- – Maki et al. (2009) randomized 60 overweight adults to green tea extract (625 mg catechins/day) or placebo for 12 weeks. The study observed a significant reduction in body fat percentage (p<0.05) and body weight (~2 kg) in the treatment group, with no serious adverse events reported.
