Theanine is one of the most useful staff I've come across. It's potency is unquestionable. Although it's effects are very subtle and can pass unnoticed by many, it does a great job of calming down extra nerve activity. It doesn't improve your mood, it just kills down extra activity in your body and brain, and provides a sense of soothing. And great price. Better to take before bed for a good nights rest.

I couldn't feel any change at first, but then I realized I stopped feeling very hungry when I haven't eaten for 4-5 hrs. Then I realized I was feeling more energetic both during day and night time. Also my endurance to stress and noise is better. Although I should stop taking it to know for sure because I am also using an antidepressant.

I normally don't prefer food extracts because most of them are equivalent to consuming only a handful of fruits a month which is not effective. I bought two of these and I get 1kg of acai berry every 2 weeks. Only this kind of servings can make a difference. It also gives a stimulating effect and energy. So if you are looking for a natural food antioxidant, 2 bottles of these a month is the way to go.

It doesn't put you to sleep right away, the 2 capsules just gives a cozy feeling and general sleepiness. Maybe more would put you to sleep right away. However it is a good product.

I used to have upper airway infections even after I had tonsillectomy. I have been using this product for 2.5 months now (2 caps a day). It gives me a sense of strength that comes from well being, and I haven't had any infection problems yet. Although these are summer days, I see lots of people around me getting sick because of temperature changes and I haven't even got a flu! Recommended for general health! It is always good to keep your immune system strong.
