L-Theanine, 150 mg, 90 Veggie Caps

I have advocated theanine, in combination with magnesium, for years. Now celebrated singer Taylor Swift has publicly said that she uses this combination to ward off anxiety. Works well! Use on an empty stomach.

Have just started these so bit early to give a review of effectiveness but for ease or ordering good ingredients, good quality, and ease of taking they all hit the mark. l-Theanine has been recommended by my doctor also for my age group. will update this review afterva month or so.

Great quality, helps me focus and keep calm throughout the day.

I’ve been using L-theanine during stressful days and it really helps me stay calm and focused at the same time. I like that it doesn’t make me sleepy, just more balanced and less reactive. The Suntheanine form feels high quality. Easy to take and works well for me.

Great for immune, easy on tummy and my health feels better and more energised

I was looking for another high-quality L-Theanine to keep in rotation, and this one from Doctor's Best is a great find. The quality is excellent, as it features Suntheanine®, which is a highly regarded, patented form of L-Theanine. This ensures the ingredient is pure and effective.
