John Weiss –
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!

I love these and will buy again
I don’t want my review to be taken down, so I will just say consult Google and YouTube for testimonials of what this combination of ingredients does for you.It’s so helpful and beneficial that I’m glad I came across a recommendation for this on YouTube.Try it!

Game changer
Take 2 in the morning and you will be awakened. People don’t understand that this is better than a monster demon drink.You just take 2 and you’re ready to go.Drink some coffee after and go. Or go to the gas station and buy a $4-$5 filthy monster for your gullet.Don’t be a loser. Just get your caffeine and theanine at a reasonable price and quick release.Or waste your money on monster crap energy life force drain

Easy to use but some might struggle with capsule size
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.

Does what you’d think
It’s caffeine. It does what caffeine does. For reference: a Celsius has 200ish mg so taking 2 of these will make me feel the same as a Celsius does. This is nice because Celsius tastes like ass and this tastes like whatever I choose to drink it with!

Alert, calm, and does the job
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.

Absolute bunk!
Size: Normal gelatin pill capsule.Nutricost has horrible quality control. This is a sugar pill in a bottle. 0 jitters, 0 focus, 0 function, 0 health benefits because there is nothing in the capsule. 200-300mg of caffeine usually makes me amped and ready to tackle my day. I took 300mg for the last 2 days and thought I was just overly tired. I decided to take 5 pills followed by another 5 20 mins later for a total of 1000mg of caffeine would should have done something. Know what happened? Absolutely nothing. Save your money and skip this junk!

Unfortunately not that effective. On the other hand it makes me anxious most of the time compared to other products. Stopped using it
Me siento defraudado, no traen cafeina, solo traen harina de arroz, ni siquiera causan efecto placebo –
Esta edición de este producto me ha parecido genial, excelente resultado
