Green tea extract

The L-Theanine, one of the essential constituents of green tea, is an amino acid that has positive effects on our health if it is integrated in a healthy and balanced diet. 
Having preventing properties against some ailments, L-Theanine is beneficial for people of every age, if it is consumed regularly. 
Researches have proven its positive effect on the immune system, blood pressure and cancer prevention. During an experience on rats, this amino acid was injected and the rats showed an unusual production of dopamine and serotonin in their brain. For humans, these secretions induce a feeling of relaxation and of deep well-being.

So, we conclude of this experience that L-Theanine has positive effects on the human brain by increasing the activity of cerebral alpha waves, which particularly benefit the reduction of stress and help to relax.

L-Theanine has antioxidant properties. Drinking tea allows reducing the oxidation of LDL (Low Density Lipoprotein) favoring the slowing down of the ageing process of some vital organs.

Green tea positively influences the blood circulation and allows preventing cardiovascular risks when consumed regularly.
