      Quality Supplement

      I take L-Theanine at times when I feel stressed and when I'm dealing with high anxiety. I feel this supplement helps me focus, relax and calms my moods. If I have high anxiety throughout the day I will take one capsule before bedtime, it calms my mind and helps me sleep. I definitely recommend this supplement.

      Great supplement with Night Rest

      I have been taking L-Theanine for a few years now in combination with Night Rest and I am definitely sleeping better. I take both about an hour before I turn out the light and for me I have noticed myself feeling calmer and more relaxed and I feel it has made a big difference for me. On the very rare occasion when I forget to take them I find myself taking longer to get to sleep...that's when I remember I didn't take my supplements and I hop out of bed to take them. It's become part of my routine now.

      Sleeping better

      I’ve started taking this L-Theanine along with 5-HTP. I was already taking Magnesium Glycinate and/or Mixed Magnesium. I’m definitely sleeping more deeply…but I haven’t tried this product alone, so all I can say is that the combination is effective.

      L-Theanine

      Great supplement for sleep. I have been sleeping better since I started taking it in combination with Magnesium Glycinate before bed. It seems to help relax my mind. Even if I wake up in the middle of the night I am still able to fall back asleep right away. Would recommend.

      L-theanine Must Have

      Good sleep is something I strive for with daily exercise, mindfulness, outdoor sunlight & nature walks, limiting caffeine, and sleep routine (dark & cool room, sleep schedule, no screen 1 hour b4 bed, yoga or body scan). Part of my nighttime routine is taking one L-theanine capsule along with 400 mg Magnesium Glycenate. I also take one L-theanine in the morning for positive moods; my go-to dual duty supplement!!
