"It’s been over a month since I started taking this to assist in sleeping, to aid in restlessness, calming my brain. I use along with Magnesium and it has been helpful in getting settled, and not waking up with 3 am. The 200mg was not effective so I started 400mg and coupled with Magnesium is the sweet spot for my sleep needs."
"I've taken other forms of L-theanine in the past, which were 100 mg and did not have noticeable sleep improvement. With Suntheanine and the Journey program, I was able to measure improvements in my sleep quality over a 30-day period and confirmed it works!"
"I've been a fan of the Tomorrow's Nutrition Suntheanine product, but am loving the new double strength 200 mg, especially for improving the quality of sleep."
"Works very well, definitely will be continuing to order!"
"I find that when I take this product, I sleep much better throughout the night. I feel better in the morning too; it's been great."
