Much Smoother Than Coffee, No Stomach Issues
I used to drink two pots of coffee most days, but it started bothering my stomach and just didn’t feel great overall. These caffeine pills helped me cut back at first, and about a month ago I quit coffee completely. It’s more expensive now anyway, and I also think it may have been making my rosacea worse. Now I take 2 to 3 of these 100 mg pills per day, sometimes 4 on busy days, and that’s all I need. Even though it’s much less caffeine than I was getting from coffee, it actually feels more effective. The energy is smoother, lasts longer, and I don’t get the same crash or stomach issues. They’re especially great for focused computer work. It’s much easier to get into a flow state and stay productive.

Perfect Balance of Focus and Calm
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.

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

Used occasionally these work
Used occasionally these provide a needed boost w/o the shakiness & upsetting stomach often associated with other caffeine supplements. Provide needed focus without the jitteriness

Cost effective energy without the jitters
This is my daily driver for energy. I enjoy coffee and tea, but with a couple of these pills in the AM and a couple in the afternoon and any other caffeine I have on that day is just for enjoyment. Great for pre-workout or long days at the office!

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

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

Horrible. Go with another brand.
horrible, terrible, taste. I'm literally burping and the powder that is in the capsule is coming out in clouds! it tastes so so bitter and the taste lingers. took on two different occasions and the same thing happened. these pills also carry next to zero caffeine effect. I bought these instead of another brand because they were cheaper, never had a problem with the other brand. ill likely just throw these away.

Negative side effects
Unfortunately not that effective. On the other hand it makes me anxious most of the time compared to other products. Stopped using it

Caffiene in smaller doses. Any where, any time.
Used to aid focus for ADHD. Wanted small caffiene doses so this 100mg version is perfect. Use 200mg (2 tablets) per day. 1 in the morning and another at 1pm. Can take any where and tweek as activities allow. Takes about 20 minutes to cut in. A lot cheaper than a coffee or tea as well needing no time. Works for me.
