  • L-Theanine is an amino acid commonly found in green tea. As a dietary supplement‚ it has been linked to healthy mental function. In Asia‚ green tea has been used for centuries as a drink that can help relax the mind and the body. Studies into the long term benefits of green tea have suggested it can promote cardiovascular health. It is also thought to help relieve stress and tension.

    Stress is at almost epidemic levels in the world today‚ with many physician visits attributed to stress-related conditions. It’s often labeled the “silent killer‚” because stress can build up overtime. The causes of your stress may be related to work‚ family‚ personal relationships‚ or other factors; whatever the cause‚ it can have a toll on your health and finances. It’s important to look out for the symptoms of stress‚ which include trouble sleeping‚ headaches‚ and muscle tensing.

    A major Japanese study looked into the effects of green tea on those suffering from psychological stress. The results suggested that the psychological wellbeing of those who consumed sufficient amounts of green tea was significantly improved; the people in the study who drank five cups every day were shown to be less stressed than those who drank less than one cup of green tea daily.

    Similar studies suggest that those who take L-Theanine in supplement form may feel stress relief‚ beginning around 30 minutes after taking it. Douglas Labs’ L-Theanine is a vegetarian supplement that provides this essential amino acid in a convenient capsule.

    Great product!

    I started taking L-Theanine by Douglas Laboratories because with Calm G I had an allergic reaction to it. I like it, but it isn't as effective as Calm G was.

    I would recommend this item to a friend.

      Mary, we strongly recommend you speak with your vet about what would be best to give your dog. No one here is qualified to advise you on whether this product is safe for pets.
