Suntheanine can have noticeable benefits with doses as low as 50mg. However, for most adults, doses of 100mg to as much as 400mg or more are often used for greater effects. In doses of 400mg or greater, some people will experience some degree of drowsiness. This is advantageous if you are using Suntheanine to improve sleep quality, but it can be a problem during the day. Doses as high as 1000 mg of Suntheanine are safe but caution should be exercised if taking higher doses when you have to drive or operate machinery.
