CanPrev L-Theanine Overview

CanPrev L-Theanine contains a unique mixture of CanPrev L-Theanine and magnesium that has the benefit of providing mental relaxation without diminishing levels of alertness. It just provides you with a sense of peace so that you can be more productive throughout the day. CanPrev L-Theanine comes from green tea extract and is very popular for its calming and soothing effect on the body and brain.

You might be wondering why not just take green tea instead of this supplement. It is because green tea only has 9mg of CanPrev L-Theanine while this product contains a whopping dose of 250mg. But you don’t have to worry because that amount is not too huge.

An overdose of CanPrev L-Theanine is near to impossible so there is no need to worry at all. According to research and clinical trials, CanPrev L-Theanine produces a certain effect on alpha brain wave activity which results to a calming and relaxing effect on the body.

    This is a high quality L-Theanine
    I love this brand of L-Theanine. I have tried other brands but this one is my favorite. I noticed that it works quickly, usually within 30 minutes. I use one capsule during the day when I need to feel calm and focused. I take 2 capsules at bedtime when I need to fall asleep quickly. It always gives me a restful sleep and I awaken feeling refreshed without any type of hungover feeling.
