Review: An Energy Boost Just When You Need It! - 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
Review: Stick with it past the first few days, it really works! - As with some of the other posters who mentioned a headache or feeling the need to take a nap mid-day when beginning this product, I felt the same way. However, I kept going with it and I no longer experience those symptoms. I assume it is your body's way of adjusting to the supplement and shift in caffeine type. Just like with anything there is an adjustment period. Now this is all I need to get me through the day. I no longer have crashes and can steadily focus on my work without the need to make tea or coffee every morning that involves sugar, which I have been off of now for 4 weeks.

Customer satisfaction is our top priority. We are always happy to help!

**Q: I am considering these, but at a lower dose. Are these pills solid that can be broken in half or are they capsules filled with powder?**
A: Check out my response to Luis's comment, but obviously it's you're body so you can do whatever you want. There are other brands on Amazon that sell this same stack but at different doses. Here ya go: http://smile.amazon.com/Puritans-Pride-Caffeine-L-Theanine-Capsules/dp/B00NAWBUHC/ref=pd_sbs_hpc_4?ie=UTF8&refRID=0YMTY1N1XRT72QW09TVVThose have exactly half of what Smart Caffeine has.

**Q: How long do the feeling of concentration last from 1 dose?**
A: Let's use today, this morning I took a pill at 9:30. I didn't redose on caffeine (coffee) till 3:55.  I would say I felt the slowdown at around 3pm. So it is pretty textbook 5-ish hours that caffeine is rated for. The difference with this pill is besides the non jittery high, the comedown is very easy and didn't feel like a crash, and that's even after a couple of meals.

### ⭐⭐⭐⭐⭐ Great Product
*by B***. on December 10, 2015*

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!
