Wholesale 99% Theanine Powder
What is Theanine?
Theanine is the most important free amino acid in tea, accounting for approximately 50%-60% of the total free amino acid content in tea. Its content in dry tea is usually 1%-2%, and its specific content varies depending on the variety and part of the tea. This special amino acid, whose chemical name is glutamic acid γ-acetamide, is a characteristic component of tea and was first isolated and identified from green tea in 1950. Theanine has a unique sweet and refreshing taste that can effectively neutralize the bitterness brought by caffeine and catechins, thereby enhancing the overall flavor of tea. From a stereoconfiguration perspective, naturally occurring L-theanine has higher biological activity, while synthetic theanine is mostly a mixture of D- and L-types, of which the D-type has significantly lower metabolic activity in the body than the L-type. This configuration difference directly affects the physiological functions of different types of theanine.
What Are The Benefits?
Blood Pressure Lowering Effects
Theanine significantly lowers blood pressure by regulating catecholamine and serotonin levels in the central and peripheral nervous systems. Its mechanism of action involves regulating the balance of neurotransmitter systems.
Neurosuppressive Effects
Theanine effectively antagonizes the stimulant effects of caffeine and has a significant calming effect. It can reduce nervous tension, promote relaxation, and improve sleep quality.
Improves Premenstrual Syndrome (PMS)
Clinical studies have shown that theanine improves the mental and physical discomfort that occurs in women 3-10 days before their period. Its sedative properties can effectively alleviate PMS-related symptoms.
Weight Loss Effects
Theanine works synergistically with other active ingredients in tea to significantly lower cholesterol levels. This lipid metabolism-regulating effect aids weight management.
Anti-Fatigue Effects
Theanine produces an anti-fatigue effect by inhibiting the secretion of serotonin (which has a central inhibitory effect) while promoting the secretion of catecholamines (which have an excitatory effect).
Neuroprotective Effects
Theanine effectively inhibits neuronal cell death caused by cerebral ischemia. Its protective mechanisms include:
· Competing with the excitatory neurotransmitter glutamate for binding sites
· Preventing glutamate-induced neurotoxicity
· Potential therapeutic value for neurological diseases such as stroke (cerebral embolism, cerebral hemorrhage), brain trauma, and Alzheimer's disease
Applications
Theanine's excellent safety and stability, as well as its unique physiological functions, have led to its widespread use in food, medicine, and other fields.
Health Products
Due to its unique functional activities, theanine can be added as a functional ingredient to health products. Examples include foods that relieve nervous tension and improve mental function, sports foods that help athletes maintain alertness, reduce stress, and enhance their competitive skills, and functional foods that prevent and improve sports fatigue.
Food Additives
To improve quality and flavor, and mitigate the bitterness of tea polyphenols and caffeine in tea, theanine can be added to foods such as beer, chocolate, chutney, pudding, and coffee.
Medicine
Numerous studies have shown that theanine has blood pressure-lowering, stress-relieving, calming, and anti-tumor properties. It is also effective in treating depression, stress, and anxiety. Theanine also has extensive applications in oncology and neurology.
Daily Chemicals
Taking advantage of theanine's antioxidant, anti-aging, and moisturizing properties, it can be incorporated into products such as facial masks, cleansers, body washes, hand creams, and lipsticks. Feed
Theanine, when added to feed, can improve immune function in yellow-feathered broiler chickens during their early growth stages and reduce the use of antibiotics in the feed.
