Introduction to Green Tea Extract Powder
Green Tea Extract Powder is a high-quality, food-grade botanical ingredient derived from the leaves of Camellia sinensis. The primary bioactive compound in this extract is theine — a purine alkaloid scientifically identified as 1,3,7-trimethylxanthine. Often referred to as tea caffeine or tea alkaloid, theine is a naturally occurring methylxanthine that delivers a range of functional properties valued across the food, dietary supplement, and nutraceutical industries.
As a leading supplier of standardized plant extracts, The Extract Factory offers Green Tea Extract Powder with a verified theine content of 15% determined by HPLC analysis. This product is manufactured through controlled extraction processes designed to preserve the integrity of the active constituents while meeting rigorous international quality benchmarks. Whether you are formulating functional beverages, energy supplements, weight management products, or food additives, this Green Tea Extract Powder provides a reliable, consistent raw material suitable for large-scale commercial production.

Active Compound Profile: Theine in Green Tea Extract Powder
Theine is the dominant alkaloid found in tea leaves and represents the principal active constituent in Green Tea Extract Powder. Chemically classified as a purine base, theine exists in both crystalline hydrate and anhydrous forms. The hydrated form typically appears as colorless, needle-like crystals with a bitter taste and no discernible odor.
Beyond theine, Green Tea Extract Powder naturally contains a spectrum of polyphenolic compounds, including catechins such as epigallocatechin gallate (EGCG), epicatechin, and epigallocatechin. These secondary phytochemicals contribute synergistic antioxidant activity, making the extract particularly attractive for formulators seeking multi-functional botanical ingredients. The standardized 15% theine content ensures batch-to-batch consistency — a critical requirement for manufacturers producing dietary supplements, functional foods, and fortified beverages at scale.
Functional Properties & Mechanisms of Action
Central Nervous System Stimulation
Theine acts as a central nervous system stimulant by enhancing excitatory processes in the cerebral cortex. This mechanism promotes mental clarity, supports cognitive function, helps alleviate fatigue, and contributes to improved work efficiency. Because of its stimulatory effect, theine is widely incorporated into energy-focused supplements, nootropic formulations, and functional beverages targeting alertness and focus.
Diuretic Activity
Theine exerts a diuretic effect through stimulation of the cardiovascular center and dilation of renal blood vessels. By increasing renal blood flow and improving the glomerular filtration rate, theine facilitates fluid excretion. This property has been associated with supportive effects in managing conditions involving water retention and cardiac edema. The diuretic mechanism also plays a role in the traditional use of tea-derived ingredients for renal wellness support.
Cardiovascular & Bronchial Support
Through relaxation of coronary arteries and bronchial smooth muscle, theine contributes to improved blood circulation and relief of bronchospasm. These properties underpin its use in formulations targeting cardiovascular health and respiratory comfort, including products designed to ease bronchial cough and mild asthma-related symptoms.
Hepatoprotective & Metabolic Support
Theine has been recognized for its ability to enhance hepatic metabolic capacity and promote blood circulation, which may assist in the efficient clearance of alcohol from the bloodstream. This function positions Green Tea Extract Powder as a valuable ingredient in hangover-relief supplements and liver-support nutraceutical blends.
Weight Management Potential
The thermogenic and metabolic-stimulating properties of theine and associated catechins make Green Tea Extract Powder a commonly selected ingredient in weight management and fat-burning supplement formulations. When combined with a balanced diet and exercise, theine-based products may support energy expenditure and metabolic rate optimization.
