Frequently asked questions

How to take L-Theanine?

The recommended daily dose of l-theanine is around 100-200 mg. When used simultaneously with caffeine, a ratio of l-theanine to caffeine of 2:1 is recommended. To promote relaxation, it is advisable to take L-theanine in the afternoon and evening. The effects can be observed 30-60 minutes after use.

How long does L-theanine stay in the body?

The effects of L-theanine can usually be observed for 3-8 hours after use. The exact time depends on the dose, metabolism, and other personal factors.

How much L-Theanine is in green tea?

A cup of green tea (200 ml) can contain approximately 8 mg of L-theanine. Black tea can contain up to three times that amount [5]. One capsule of standardized extract is equivalent to 12 cups of green tea or 4 cups of black tea.
