Not good for health
I have difficulty in falling asleep and I don't typically get refreshing sleep. After reading very good reviews of Suntheanine. I tried it multiple times, separated by big gaps between them. Each time, I found that it does have a calming effect and helps in sleeping as well, but there are many harmful effects that include: 1. Lower back pain due to muscle stiffness. 2. Lowers immunity 3. Fluctuations in body temperature 4. Effects eyesight for reading.
