Product Description

1. Product Introduction

Our Theanine Extract is a high-quality plant extract finely refined from premium natural green tea raw materials. Rich in L-theanine, tea polyphenols, natural amino acids, trace minerals and polyphenols, it delivers excellent effects of soothing and calming skin, repairing sensitivity, brightening and evening skin tone, as well as natural physical and mental conditioning value. Widely applied in beauty and skin care, food and beverage, dietary health and other industries, it has been highly recognized by the market.

2. Active Ingredients

L-Theanine and Tea Polyphenols

The main active ingredients of theanine extract are natural L-theanine and tea polyphenol compounds. These active substances are renowned for powerful antioxidant, soothing stabilization, calming repair and skin brightening properties, serving as the core functional components of theanine.

L-theanine and tea polyphenols are key natural active ingredients intensively studied in the industry. Studies have proven that these components can effectively neutralize free radicals on the skin surface and in the human body. Free radicals are the main cause of skin oxidative dullness, fine lines, sensitive skin, body aging and sub-health conditions, which can significantly improve multiple oxidative damages.

Natural Amino Acids and Trace Active Substances

Theanine extract also contains abundant natural free amino acids and trace nutritional active substances, featuring an elegant and fresh natural green tea aroma. These ingredients not only endow the product with a pure and mild plant texture, but also deliver excellent functions of physical and mental soothing, emotion regulation, gentle skin moisturizing and long-term skin stabilization. They gently nourish the skin and physical condition, bringing multiple comprehensive maintenance benefits.

3. Appearance and Properties

Color

Conventional-grade theanine extract ranges from light yellowish green to brownish yellow; high-purity grade presents light tender yellow, and high-precision grade is off-white with slight yellow tone, free of impurities and agglomeration.

Form

This product is available in fine powder and concentrated liquid extract. The delicate powder is easy to formulate and suitable for producing dietary supplements, solid functional foods and cosmetic powder raw materials. The liquid extract features higher concentration and fully retained bioactivity, perfectly adapting to deep processing scenarios requiring high concentration and high permeability.

Solubility

Conventional theanine extract powder has moderate water solubility and shows better dispersion and dissolution effects in alcohol-based and oil-based systems. Supported by advanced extraction and modification technology, water-soluble theanine extract has achieved stable mass production. It is compatible with various water-based production systems to fully meet diverse application needs of different industries.

4. Health Benefits

Antioxidant Protection

As mentioned above, L-theanine, tea polyphenols and amino acids in theanine extract possess strong antioxidant capacity. They can effectively eliminate free radicals in the body and on the skin, protect cells from oxidative damage, slow down the aging process of the body and skin, and reduce the risks of skin oxidative dullness, rough sallowness, fine lines, sagging and physical sub-health problems.

Anti-inflammatory and Soothing Properties

Multiple studies have confirmed that theanine extract has remarkable anti-inflammatory and soothing effects. It can effectively relieve superficial skin redness, heat, sensitivity and barrier instability. Meanwhile, it assists in regulating mild internal inflammation of the body, contributing greatly to skin calming, barrier repair, sensitive skin improvement and metabolic inflammation conditioning.

Body Metabolism and Physical & Mental Conditioning

The natural active ingredients of theanine exert positive regulatory effects on human metabolism and physical and mental status. They help adjust body circulation, relieve physical and mental tension and fatigue, improve irritability, anxiety and mental stress, stabilize bodily functions, and ameliorate sub-health conditions caused by excessive daily pressure and irregular schedules.

Metabolic Maintenance and Health Care

Natural amino acids and polyphenols in theanine extract gently regulate human metabolism, balance body circulation and relieve physical and mental stress. They alleviate fatigue, listlessness and restlessness caused by long-term mental tension and metabolic disorders, realizing mild comprehensive body soothing and conditioning.

Only high-quality mature green tea leaves with complete shape, fresh color, no mildew, no insect pests and no impurities are selected to ensure high-quality raw materials, stable ingredients and consistent quality from the source.

Extraction Technology

Our optimized and upgraded extraction process maximizes the extraction of core active ingredients including L-theanine, tea polyphenols and natural amino acids, while completely retaining their molecular structure and biological activity to avoid active loss. Advanced technologies such as supercritical fluid extraction, low-temperature solvent extraction and spray drying are flexibly adopted according to different product grade requirements to guarantee product purity and quality.

Testing and Analysis

Each batch of theanine extract undergoes strict tests on active ingredient content, purity and overall quality. High Performance Liquid Chromatography (HPLC) is used to accurately detect the content of core components to meet quality standards. Meanwhile, rigorous safety tests on microorganisms, heavy metals and impurities are carried out to eliminate harmful contaminants and ensure full compliance with safety regulations.

7. Packaging and Storage

Packaging

Our theanine extract is packed in high-quality sealed containers to effectively isolate light, moisture and oxygen and prevent oxidative deactivation of active ingredients.
