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: Great Variant for a "Grown Up" Energy Supplement! - A school teacher who is a drama director. I don't use this a lot, but when needed for those longer afternoons rehearsing at the theatre. If I take 1 Smart Caffeine at lunch time, I coast energetically through the rest of the day without feeling caffeine jitters. I prefer taking it with my lunch around 12:30, but if I forget, and take 1 later, if I have 1 tablet no later than 2:00 PM, it's still effective, and does not have a linger after effect, when I go to bed. It doesn't effect my somewhat fragile sleeping pattern. ## Features - 💡ALERT FOCUS AND PRODUCTIVITY: Take this Smart Caffeine Supplement with L-theanine for when you need alert focus and long lasting energy.

Smart Caffeine is dairy free. We hope this helps! If you have any other questions or concerns, please let us know by reaching out to us directly -- contact@thegroupdeal.com. -Zoey, Customer Service 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ An Energy Boost Just When You Need It! *by T***W on December 27, 2024* Are you exhausted and mentally plus physically worn out?
