I love this stuff. So good. Helps with energy, focus, makes you feel calm and alert. I take one every day. Sometimes two. On an empty stomach in the morning. Gives me a good boost with no crash. Better than coffee in my opinion. Good for adhd if you want natural options

Smart Caffeine

Smart caffeine is great. It helps me feel energized and focused at work. For me it seems to last about 6 hrs and kinda wears off. No crash though. The Theanine is perfect with it. Just feel in a good positive mood, not jittery. Small capsule so easy to take. I really like the benefits, helps get me through the day feeling good even when I don't sleep well.

Not my favorite

I bought this one because my favorite caffeine l theanine capsules were out of stock. And it said no crash but i got bad heart palpitations with this one, not much benefit and alertness/energy as others i tried. The capsule size is small and the ingredients and quality are not as good as others i tried

Used for long distance traveling. Helped with jet lag control as an alternative to drinking caffeine. Not too strong for me.

Caffeine & ADHD help

Was told this is good to help with ADHD and bonus that it has caffeine for added energy. I like to take this in the morning for added health benefits to help my mother and focus better.

Good, Smooth feeling

These pills give me good energy that helps me focus on my tasks without making me feel shaky. It's like the awake feeling from coffee, but much calmer and smoother. I can get my stuff done and I don't get a crash later.
