NATURAL STACKS Smart Caffeine Pills - 100mg Caffeine + 200mg L-Theanine Supplement - Supports Energy and Focus - No Jitters and No Crash - 60 Capsules

Are you exhausted and mentally plus physically worn out? Life can do that to you and sometimes you need a little boost of caffeine energy to get through another day. I was feeling emotionally worn out from dealing with a situation that was not resolving itself and I was having low motivation to get things done.Then I remembered I had these capsules and figured one couldn't hurt. I will say these do give you an energy that is more long lasting and it didn't make me feel anxious or wired and I felt no crash besides that I ended up going to bed a little earlier that night.I'd say from the time I took one capsule to the moment I got active was about 20 minutes. I cleaned my whole kitchen, did several loads of laundry and did other things around the house that needed to be done. I literally felt like all the negative emotions I'd been feeling dissolved into a sense of happiness and peace.I will however say that you don't want to take these if you are not near a restroom because I found out these have a diuretic effect like coffee. Make sure to drink plenty of water even if you only take one capsule. I am not a doctor, nor is this medical advice. Some people also can't handle much caffeine due to heart or anxiety issues. So use with caution.But overall I felt these were safe enough for me and did give me more energy than a cup of coffee. I personally would not take more than one capsule at a time during a day and would not take these every single day. I consider these more a last resort when I'm really low on energy or feeling emotionally drained. For that they work like a miracle!~The Rebecca Review

It works great! You have no jetters and no crash. Love this and I have used fir two months every day!

Currently trudging my way through grad school while working, and often find myself with low energy and unable to focus. Must be the lack of sleep huh? Wrong. Despite being extremely busy, I usually average about 6-8 hours of sleep per night, the exact same amount I had before I went back to grad school. Because of this, I figured I would get something relatively natural and low impact to help increase my energy and focus. I opted for this particular brand because the reviews were pretty good, the packaging and marketing looked rather legit ( I know this may seem like a crazy thing to go off of, but with vitamins if they look like they belong in an infomercial, I feel nervous.) and the price was right. I got them in the mail, and within a week I noticed that I had increased energy, and after two weeks I saw that it was even more intensified. With that said, I still hadn’t seen any improvement in focus, so I decided to “stack” (new supplement lingo I learned from a guy at a health foods store) another supplement, called NootropX - 90 caps - Mental Focus and Concentration Supplement With Memory Enhancement For Extreme Clarity and Alertness - Instant Brain and Memory Power Boost From Patented AES® Absorption System - The Ultimate Brain Vitamins which is a little bit more geared towards the focus aspect I was looking for. After two weeks of taking both of those, I noticed that I was performing better at school and work, and I had the energy to do even more than I had hoped for. My work was coming out better, as I had been able to focus more. I definitely recommend this supplement to anyone who is looking for an energy boost, and even though it didn’t give me a boost in focus, it’s still a great product and since everyone’s body is different it may work for you!

These pills are great! I used to drink coffee all the time but can't anymore due to stomach issues. Tea does not do enough and soda is not as healthy. As such I looked into caffeine pills.This brand packs a good little punch that lasts all day and doesn't make me crash or feel jittery. I have an hour commute to work and an hour back and these pills keep me awake and focused. They are easy to swallow and no taste.Also, I find I am able to take more caffeine such as maybe espresso with this and still feel okay. I would recommend taking it before your morning shower to let it kick in. As another note, these pills do not cause me any GI issues like coffee does.Pros: easy to swallow, keeps me focused, no jitters or crashCons: effect dissipates after constant use, sometimes causes anxiety (infrequent)

Awesome product

You might not get a boost from this if your brain is sensitive to L-Theanine. You might actually have the reverse affect and get a little sleepy in spite of the caffeine. I'm the type that gets sleepy if I take L-Theanine so these pills put me to sleep. L-Theanine is great, but for some brains it's calming effect makes them super drowsy. You will have to experiment with this. For those of you who need the L-Theanine, I've heard the combo with caffeine works great. For me, unfortunately, it doesn't work.

No side effects…very effective.

Going from regular caffeine pills to this made me sad. It was like a sleeping pill. not smart for me. We all react differently to substances. Maybe for someone else it works great. I also have chronic fatigue syndrome, so maybe i just need a bigger kick. This was a fail for me
