Perfect Balance of Focus and Calm

James SandovalNovember 13, 2025

I started taking Nutricost Caffeine with L-Theanine because I wanted a cleaner, smoother energy boost without the jitters or crash that usually come with coffee or energy drinks. After a few weeks of using it, I can say it really does the trick. The combination of caffeine and L-theanine gives me steady focus and alertness, especially during long workdays or early mornings, but I still feel calm and collected instead of wired. It’s great for productivity—I can get through meetings, projects, and workouts with good energy and mental clarity. Each capsule is easy to take, and I appreciate that it’s non-GMO and gluten-free since I’m mindful about ingredients. The bottle lasts a long time, so it’s a great value for the price. The only small downside is that it’s easy to forget you’ve taken it since there’s no “rush,” but that’s also what makes it so smooth. Overall, it’s a solid supplement for anyone looking for a focused, crash-free boost without overdoing the caffeine. Read more

MykeDecember 19, 2025

Perfect, just what I needed. The low dose is better if you are going to take once a day and don’t drink coffee. You can minimize tolerance and the l-theanine will smooth out and jitters. Don’t take 10-12 before bed. Functions as intended and helps me focus and be productive. Strength is great, you don’t want more I promise you if you want to use it every day. I sleep fine as long as I don’t take 10-12 hours before bed. Easy to seallow Read more

Great product for energy and focus, and without the jitters.

John WeissAugust 15, 2025

Great for an energy boost without feeling nervous. These are the perfect amount of caffeine to l-theanine ratio so that I can have extra energy from the caffeine while feeling calm and focused from the L-theanine. It is a great deal getting this bottle of 240 capsules for so cheap. Nutricost makes great quality supplements for a great price and these are excellent. They are easy to swallow capsules and also easy to open and take the powder directly on the tongue for faster effects; it does not taste bad at all. I take them usually twice a day to keep up my energy and they also help suppress my appetite so that I don't eat too much or crave sweets. I highly recommend these for anyone who needs extra energy or to help with mood or focus. They may even help you lose weight. My wife and I both take them daily and they keep us feeling good and full of energy. Great quality, great price, easy to swallow, and actually works! I highly recommend these! Read more

Easy to use but some might struggle with capsule size

JenniferOctober 2, 2025

Really good and efficient caffeine that has L-theanine to help with brain fog. Capsules are pretty large, so if you struggle with swallowing pills, I would definitely consider small options. Read more

It feels good puts a pep in your step even if you are older.

Kristie MentzerDecember 21, 2025

I am person who has been struggling with my weight since a few medical surgeries. I take nerve inhibitors that make me feel so pudding. So not only is the ability to exercise meek but there is a ton of brain fog also. I bought these on a I’m broke and need a quick fix whim to try to avoid caffeine withdrawal. I live on energy drinks and Starbucks to stay functional. I feel like sometimes we overlook the simplest things. Not only did popping one of these in the morning wake me up but I had been drinking sugary caffeine for so long I forgot what it felt like without them. I felt energetic and good . I think the good part is from the ltheanine. I am pushing 40 at 250lbs so I was worried about side effects on the heart ecceta there was not any. I felt the energy as if I was young I’m always wanting to sit down because I feel so bogged health wise but this made me want to get up and go. I got through work without feeling stress thanks to the theanine. And a bonus I did not consider it had me not even wanting food for hours. Replacing all that sugar with a clean energy I noticed silly stuff at my age like I could smell better my senses were more functional and focused. This sounds blown out of the water but with all my health issues days like this were slim to non. I decided after just two days this is the solution to dieting and breaking away from energy drinks. I definitely recommend the L theanine version because who doesn’t want to feel good while they’re awake instead of jittery chaos. So if you were on the fence like me thinking I’m too old it’s too scary don’t be. We can get up and enjoy the day with this. Read more

Alert, calm, and does the job

J.KimJanuary 16, 2025

I am new to caffeine pills. I purchased my first set of caffeine pills from a different company on amazon and liked them well enough but I wanted to try a caffeine pill with l-theanine. I have been using these for 2 months and think that I have given it a good shot for an honest review. Though I don't know all the benefits of L-Theanine, what I do know is that it helps to feel less anxious and more relaxed. I definitely need that and I feel that. Coworkers have commented that I don't look stressed (even if I am internally). I am not as bothered as I typically would be. I am an RN, have 4 kids, and i typically rely on caffeine to make it through the day. I am drinking less coffee because of these caffeine pills. I take one at 5:30AM before my shift with my vitamins and then I head to work. During my lunch break I take another pill and I am set for my 12 hour shift. I am drinking more water, don't feel sluggish, am not jittery, and sleep well at night. I was nervous about trying caffeine pills - fear that I would get addicted or just the concept of taking pills for energy was weird...but my fears are abated. I am energized and don't take the pills on my days off from work, so not addicting. Read more

A BARGAIN !

TheCriticDecember 5, 2025

I have teeth that stain easily from drinking tea/coffee. So, I tried having my "wakeup cup" in capsule form. One of these contains a little less caffeine than a Tall Starbucks. One or two capsules with water start my day nicely and the teeth have stayed white! Recommended. Read more

Ok, but capsules need help

Rod SchulzDecember 29, 2025

The caffeine is effective, but the capsules are horrible for sticking in your throat. I've ended up coughing out caffeine dust more than once; make certain to drink plenty of water to wash them down! Read more
