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!

This product gives me the caffeine I need without the sugarless additives that destroy the bugs in your gut.

I bought these because I wanted to boost my concentration and productivity throughout the day. I was also looking for an alternative to coffee that didn’t give me jitters or anxiety. I have a very low tolerance to caffeine, so one capsule was too much for me. It gave me the same effect that coffee usually gives me. I almost gave up on these, until I decided to only take half a capsule. Turns out that was the right dosage for me and it has worked wonderfully. I have more energy in the morning and my alertness has increased. If you find that these give you jitters, try finding what is the right amount for you.

No side effects…very effective.

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.

Awesome product

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
