Review: Wonderful Product - I LOVE this product! I take one pill in AM and one pill in PM and have noticed marked improvement in mood and calming effects without drowsiness. I highly recommend 👌
Review: Positive effects on high anxiety - I’m struggling with terrible anxiety (GAD and OCD symptoms triggered by relationship/ life transition stressors nearing panic). Researching what I could take not only to help reduce anxiety overall but in moments of increased anxiety, L-Theanine was a consistent, strong recommendation. Initially, my negative anticipation was high I doubted how much a supplement could, would help: this is my third time buying this product from desertcart! It’s wildly effective, helps with focus (not my concern, but a bonus!) and, most importantly REDUCES anxiety symptoms!!! Easy to swallow without taste for those curious!
