For relaxed sleep

Someone told me to take this and I did. Originally I take it during the day to calm my nerves. But my sister told me its also good to take before bed for a restful sleep. It works for me!

California Gold Nutrition, L-Theanine 100 mg (AlphaWave®)

Great quality supplement. Capsules are easy to swallow and have a neutral taste. I like the clean ingredient profile and reliable brand. Helps support relaxation and stress balance without making me sleepy. I also noticed my skin looks calmer when stress levels are lower. Good value for the price.

Great size

They are really small and easy to take. I've noticed that they work better if you take 2 in the morning rather that 1 morning and 1 afternoon.

Good relaxer

L-theanine 100 mg was my first experience with this supplement. It provides very good relaxation, especially when taken together with a B-complex vitamin. Whenever I woke up in the middle of the night, I took this combination. If you didn’t have stress the day before and your state is already more relaxed, the effect is more noticeable, you wake up with a very clear, well-rested mind.

Great Product, will continue to buy.

I have purchased this many times over again. It definitely has the calming effects and does what it’s supposed to do. I also take it for the benefits in the gym with energy and for protein synthesis for muscle growth. quality ingredients. Good size pills not too big easy to swallow. No bad taste. I will purchase again and again.

I order from iHerb often. This is my standard 4–5 star review, meaning the product is excellent and exactly as described. It works as intended, is packaged properly, and I genuinely enjoy using it. I’ve either reordered already or plan to when I run out. Like if this helped.
