Ready to ShipL theanine's main raw materials are found in green tea leaves, but some are synthetically made. While all forms are effective, natural L theanine is preferred for its purity and additional health benefits. In contrast, the synthetic version is often cheaper and used for mass production.
Green tea leaves
L theanine, an amino acid, is primarily found in green tea leaves. It accounts for 1-2% of the leaves. When steeping the tea, only a small amount of L theanine is absorbed into the body. Green tea is a natural L theanine source, as it contains high concentrations of this compound. It is, therefore, preferred for supplement manufacturing.
Black tea leaves
Black tea, like green tea, contains L-Theanine, though in smaller amounts since it undergoes more oxidation. Some black tea varieties, like lapsang souchong, have slightly higher L-Theanine levels than others.
Tea mushrooms
Tea mushrooms, also known as tea fungus, are a cultural and historical remedy for tea brewing that originated in China. They are SCOBY (symbiotic culture of bacteria and yeast) colonies that ferment sweetened tea. Though not well studied, some fermentation advocates believe they increase l Theanine concentration.
Matcha
Matcha is powdered green tea made from tea leaves and stones. It is a popular drink and supplement that contains high L Theanine levels. With matcha, the whole leaf is consumed, so it has more L Theanine than steeped green tea.
Decaffeinated tea
Decaffeinated tea can be any type of tea, such as green or black tea, but with the caffeine removed. It still contains L-Theanine. Some decaffeinated tea methods may reduce L-Theanine levels.
L Theanine raw material synthetic
Some L Theanine supplements are made in chemical labs to create in bulk for more affordable supplements. Though pure and identical chemically to natural L Theanine, some may prefer it because it's less expensive and mass-produced.
L theanine improves health and wellness in multiple ways. For myself, it helps reduce anxiety and stress, improve sleep quality, and promote relaxation without drowsiness. Several studies on the brain and body effects conclude that L theanine increases alpha brain waves, promoting relaxation and calmness.
People take L theanine with caffeine to improve focus and attention. Multiple studies have confirmed that this combination improves cognitive performance, mental alertness, and task completion without increasing heart rate. Because of these benefits, L theanine is a common ingredient in nootropic supplements, enhancing brain health.
L Theanine is also combined with other amino acids and vitamins in sleep supplements to promote better sleep. It helps people who find it hard to sleep relax and fall asleep. L theanine has hydrating and soothing properties that help repair damaged skin tissues and cells, improve overall skin health, and reduce signs of aging.
This makes it a common ingredient in skin care products like serum and moisturizer and supplements for skin health. L theanine is also added to weight loss supplements. It reduces stress-related eating by promoting relaxation while reducing cortisol, the body's stress hormone, which is associated with increased appetite.
By working with other ingredients in these supplements, L theanine helps reduce hunger and cravings, making it more effective for users. Because it occurs naturally and is synthetically, L theanine is a common ingredient in functional foods and beverages like protein bars and drinks, smoothies, and teas.
L theanine has multiple specifications and features that affect the buyer. Here are some key factors:
Specification
L theanine supplements contain 100-200 mg in each dose. That is why it is common in nootropic and sleep-enhancing supplements. In skin care products, up to 200 mg L theanine is common in serum formulations where it combines with other skin-repairing nutrients. Weight loss supplements contain small amounts, like 50 mg per dose, combining L theanine with other amino acids, proteins, or vitamins.
Purity
Purity refers to how much L theanine is in the supplement and whether it's a natural or synthetic form. The higher the purity, the more L theanine in the supplement or product. Natural L theanine supplements have higher purity because additional compounds in green tea improve L theanine absorption and effectiveness. At the same time, synthetic L-theanine supplements may have lower purity because some manufacturing processes reduce L Theanine concentration.
Bioavailability
The body absorbs L theanine in teas and supplements differently. Theanine in green tea is better absorbed than in synthetic form and understood to be more effective. However, it's hard to quantify bioavailability because studies measuring it are few. Those that exist measure it using plasma concentration as the benchmark.
Form
L theanine is usually found in capsule and tablet supplements, powder, and liquid. It is commonly used in skin care products as an ingredient in serum, moisturizer, and cream. The raw material is usually in powder form for manufacturers.
Storage conditions
L Theanine should be stored continuously in a room at 20-25 degrees Celsius. Also, avoid moisture exposure and sunlight and keep it in an airtight container to maintain its potency and effectiveness.
L theanine has multiple uses across different industries. Here are some common uses:
Stress and anxiety relief
L Theanine is widely used in supplements promoting relaxation and calmness without drowsiness. It competes with glutamate, a neurotransmitter linked with excitement; thus, it increases GABA, dopamine, and serotonin, calming and relaxing the body. L Theanine is popular in combinational supplements with caffeine that improve focus and cognitive performance to promote mental alertness without increasing heart rate.
Sleep improvement
L theanine improves sleep quality and reduces insomnia symptoms when combined with other amino acids like glycine and tryptophan in sleep teas and supplements. Because L theanine is an alpha antagonist, it blocks alpha and increases theta waves, promoting relaxation and sleep. This makes it suitable for people who want to improve their sleep quality.
Skin health
L Theanine contains hydrating and antioxidant properties, improving skin health by repairing damaged tissues, reducing signs of aging, and keeping the skin moisturized. It is a common ingredient in serum and moisturizer. It is also found in serum and creams for damaged skin and in beauty supplements for skin health.
Weight management
L theanine and other supplements combine with proteins and vitamins help reduce hunger and cravings, making them effective for weight management. L Theanine works synergistically with other amino acids like glutamine and proteins to reduce hunger by increasing satiety and lessening the stress hormone cortisol, associated with emotional eating. It is also found in functional foods like protein bars.
Brain health and cognition
L Theanine is popular in nootropic supplements promoting brain health with other ingredients like ginseng, vitamins, and amino acids. It is a common ingredient in tea, matches, and other drinks marketed as nootropics. L theanine naturally improves attention and focus without drowsiness.
Natural L theanine supplements are preferred because they are pure and effective. However, some are cheaper and more convenient to use than their natural counterparts. Also, some synthetic L theanine undergo advanced purification and quality control processes to be more effective than natural L theanine. Buyers should also look at the L theanine source. L Theanine from Japanese and Chinese green tea contains higher concentrations than other sources.
The branded extraction technique determines the L Theanine concentration and availability in the product. For instance, L Theanine in Matcha tea is higher because the whole leaf is consumed, unlike steep green tea. Buy L-Theanine with other complementary ingredients like vitamins B and D, magnesium, and alpha GPC for more potency. Always check the supplement form. L Theanine is commonly in capsule, tablet, and powder forms. Those who want quicker effects should purchase L Theanine in liquid form, as it works faster.
Avoid supplements with artificial additives and sweeteners that reduce the product's effectiveness. Read the label and know the L Theanine amount per serving to avoid overdosing or underdosing. The best L Theanine supplements contain 100-200 mg per serving. Consider different brands and options for more availability. Also, check online for other users' ratings and reviews for more information. Buyers should only purchase L theanine supplements from reputed distributors with valid wholesale licenses.
Before placing bulk orders, ensure to sample the products first. Distributors not within the buyer's community are likely to require a business document to verify and process the order.
