Suntheanine is the premier, patented form of the amino acid L-theanine. Suntheanine is the purest form of L-theanine on the market today. L-Theanine is an amino acid derived from green tea that is responsible for the relaxation-inducing effect of tea consumption. Suntheanine has been shown to promote an alert state of relaxation. This is characterized by an increase in alpha brain waves (signifying a relaxed, alert state) and a decrease in beta brain waves (signifying an awake, excited state of mind). Suntheanine may also improve sleep quality, enhance mental acuity and soothe away tension and nervousness.

  • Promotes a relaxed state without drowsiness
  • Eases stress and everyday nervous tension
  • Promotes a positive mood and alertness
Suggested Use

Adult Use: Take 1 capsule daily, or as directed by a health care professional.

No jittery feeling like I may get from the usual cup of tea and smooths my day a bit!

Great for anxiety or taking the edge off of caffeine!

Posted by 5249498575345316039 on Feb 18, 2016

I like to take one of these before I drink coffee, which takes away the jitters I normally get. Gives me some really focused energy. It also calms me down if I'm upset about something, or just after a hectic day. Best value I could find for L-Theanine.

raised my anxiety, no calming effect

Posted by 5692560753340512198 on Jan 30, 2016

Unfortunately it raised my anxiety I felt no calming affect. I even tried taking three capsules and my anxiety got worse. I'm going to try it with melatonin since I saw a comment on here that recommended that combination. I'm just going to stick with inositol as my anti-anxiety since that works for me.

L-Theanine for Anxiety

Posted by ReaCovery on Jan 03, 2016

I'm still experimenting with these, trying to find my optimal dose and when best to take it, but it works great to lower anxiety and calm my nervous system down. I'm trying several brands and this one works fine. I'm recovering from protracted antidepressant withdrawal, and high levels of anxiety and fear have been some of my worst symptoms and this has been one of the few supplements which has really helped. I have to be careful not to take too much or I tend to get a bit apathetic and unmotivated to do much.
