- Dietary Supplements: L-theanine is often available as a dietary supplement in the forms of capsules, tablets, or powders. The content per serving typically ranges from 100mg to 200mg, and it can exert a relaxation-promoting effect within 30 to 60 minutes after consumption.
- Food Raw Materials: High-purity L-theanine raw materials are available on the market. For example, the L-theanine raw materials supplied by Natural-Field have a purity of ≥98% (tested by HPLC). These raw materials can be used in the production of food and health products, as well as in scientific research experiments.
- Beverages: L-theanine can be added to various beverages such as tea drinks, coffee, cocoa drinks, ginseng drinks, and beer. It can improve the flavor of beverages by reducing the bitterness caused by caffeine and tea polyphenols. Additionally, it promotes the production of alpha brain waves, helping people enter a state of relaxation. Moreover, L-theanine has a synergistic effect with caffeine and is often used as a key component in formulations designed to boost energy and focus.
