Natrol High Caffeine 200 mg per Serving, Energy Support Supplement for Adults, 100 Tablets, 100 Day Supply

These are the best caffeine pills I’ve ever tried. Even taking half a pill gives me clean, steady energy for 12+ hours with no crash, no jitters, and no burnout afterward. I felt alert, focused, and energized all day. My only complaint is that they’re always sold out. I wish I could stock up because nothing else works like these!

I've tried a lot of energy shots and drinks in the past, from Monster Energy, Rockstar to X-Mode. I decided to try these to skip the sugar and junk that comes with energy drinks and found these to be excellent. They not only boost my energy levels but also brightens my mood, keeping me very positive. There is no crash like with other energy supplements, filled with sugar and unnecessary ingredients. These pills are flavorless so don't expect anything like an energy drink. I down these with water. I break them in half and take one in the morning and one in the afternoon if needed. They are easy to split in two. I find that taking an entire pill at once gives me heart palpitations. The cost is extremely affordable. I do take them sparingly, no more than 3 times per week. They lose their effect if I take them daily. I will continue to use these as needed as they work as intended and the cost cannot be beat.

A good brand with a good price that works as intended. While it may not have some of the other beneficial types of caffeines (like green teas) or other herbal additives that keep the "cras" from happening, these are a perfectly fine caffeine pill that will keep you awake and moving through your day. I take one of these in the morning to help me be extra productive at work. Good price means I don't mind sharing or misplacing a pill - on the flip side you do notice the occasional crash when they wear off but not nearly as bad as other types of caffeine supplements.

Worked really well, had to divide the tablets into quarters and take over the coursed of an hour/half hour.

The pill is great because it replaces that cup of coffee in the morning when I don't have time to make it. Normally, I take 1 cup in the morning and 1 at noon if I really need it. Have been taking it for 3 weeks. When I took it in the morning, I don't feel any jitters or headaches, but feel awake (not super energized) enough to last till the afternoon. However, I noticed that when I work out, it is really difficult to catch my breath and my chest feels tight. I tested it to see if the symptoms were caused by the pill, so I stopped taking it for a week and my workouts improved immediately. I suggest taking it on days when you don't do intense workouts.

I don't always want to drink coffee or tea, or have time to do so. Sometimes I'm somewhere where the coffee sucks, and I am not someone who will go to Starbucks to buy a cup - I'm picky about coffee, unless the situation is dire. Same with tea. Also, both take time to kick in; I don't always have that time. Enter the caffeine pill. Portable, cheap, and you can knock back one anywhere. Hits you all at once - which for me, is a good thing. I used to take Jet Alert, but they just weren't that effective at the 200mg strength, though 2 of the 100mg seemed better. But why waste money? So I did some research. Enter Natrol High caffeine. It feels stronger than Jet Alert and cleaner somehow. I can bite one in half with my front teeth (the original pill splitter) if I need more later in the day (I keep the other half in a separate case, I'm not that gross). My favorite use is setting my alarm a litter early, washing one of these down, then going back to sleep until I need to get up. I'm usually awake before my 2nd alarm and the morning goes a lot more smoothly. I am not a morning person, but these help me fake it sometimes. Ok, that's a lie, but I can get up and be much more functional than I used to be. I'm not standing in the shower staring at the wall for 10 minutes. Or trying to lather hand lotion on my face instead of cleanser. Or trying to brew ground hempseeds instead of coffee (insert vegan joke here). Hemp is a good protein source, but terrible coffee substitute.

Got tired of drinking tons of energy drinks and coffee doesn't work anymore. These are 200mg which isn't alot compared to all the energy drinks I would consume in a day. Maybe 2 Celsius and 3 V8 energy. The first day I took a whole pill and ended up with headache and very weak (my own fault) because I didn't eat anything...lol. I then started taking half a tablet and they don't make you all jittery. I think a person needs to eat also so that their body has fuel. I now take half to a whole and I still sometimes need to add an energy drink. But I'm also overweight and don't sleep well. They are definitely worth a try for anyone wanting caffeine without drinking all the extra calories. No bad aftertaste either.

I am surprised to read so many reviews saying these did nothing. I had the opposite effect where they were way stronger than I anticipated. I am used to drinking 300mg in an energy drink so I took a whole 200mg tablet, but 200mg of these caffeine pills gave me heart palpitations. I have been taking half of a tablet instead, and that gets me a nice energy boost without any side effects. Takes about 20-30 min to notice the effect. Much less expensive than energy drinks so I'll keep taking them. Can't afford energy drinks with grocery prices as high as they are currently.

I just started to use it and see the effects

No sentí una diferencia al tomarlas. Pensé que era yo, compartí con unas amigas y realmente no sintieron algo.

I HAVE NEVER COME ACROSS SUCH A GREAT PRODUCT. IT HAS ENHANCED MY MOOD AND MY ABILITY TO CONCENTRATE. I HIGHLY RECOMMEND THIS GREAT PRODUCT.

Nice & Effective

Worth every penny
