Lowers blood sugar
I find this product very useful. I purchased my first bottle in late July, starting with 150mg at bedtime, and it has effectively lowered my morning fasting blood sugar! I noticed this while testing frequently. Perhaps this is due to claims online that theanine can reduce cortisol, a factor in some "dawn phenomenon" cases related to insulin resistance and type II diabetes. While I cannot confirm this, my fasting glucose readings have decreased by 30 points or more! During a particularly stressful time in my life, I took a higher dose of 300mg, which helped me sleep soundly and alleviated my anxiety. Overall, I'm very pleased, though individual responses may vary.
