Brief Answer:
It is safe

Detailed Answer:

Hi,

Theanine is herbal product so it is safe and there are no reported serious interactions and side effects. Some people may experience nausea if taken in excessive amounts.

Considering usefulness, you should not expect miracle here. It is useful for some condition more and for some less. For relaxation, fight against, anxiety and immune system improvement and blood pressure, there are data that suggest positive results, but for cancer, there are no such proves.

Wish you good health.
Regards
