Extended Release Caffeine Pills + L-Theanine + 200mg for Energy & Focus + No Jitters, No Crash + Natural Caffeine Supplement - 60 Capsules

Coffee gives me headaches and energy drinks have a bunch of unhealthy crap in them. So I was looking for the healthiest caffeine I can find so I tried these. I've only been taking one in the morning and it seems to give me steady energy throughout the whole day. I have a low caffeine tolerance, but I was very impressed. All other forms of caffeine I've tried seem to give a spike then a crash, but these don't. Honestly it's amazingly cheap too compared to making coffee or buying an energy drink everyday.

On daily, I average 300-500mg caffeine intake via espresso, kcups, karak chai, v8 energy or some combination of these forms. When I took this last year for Ramadan fasting, I noticed these helped relieve my headaches, crashes and heavy eye lids throughout my workday. I took two pills usually, and few mornings with less sleep night before, three pills would do the trick. These were super effective, and i had sustained energy levels. They did NOT upset my stomach or make my heart murmur or anything since I already have a high tolerance for caffeine.

Just ok. I took one it wasn’t enough. I took 2 and went to sleep. The sweet spot is taking 1 waiting 2 hrs or so and taking another one.

As a Class A HAZMAT CDL driver, I can tell you that alertness determines life or death in a split second on a daily basis. These time release pills are a LIFE SAVER when we're tired. I've never taken anything that makes me feel not only alert, but also makes me feel like I had a good night's rest while operating on only 4 hours of sleep! I'll use this product as long as they manufacture it!

Heavy chemicals and cologne like smell and taste. Not as expected or orderd

I've tried a lot of different caffeine products and most still have a little bit of a jittery feeling so I was expecting this one to have that too. However, I was really surprised that, while being effective, it wasn't causing any of the jitteryness or clenching my jaw or any of the side effects I usually get. I also didn't really feel tired or gross when it wore off. The amount seems perfect and it seems to last a bit longer than alternatives like no-doze. I really like this product and would purchase it again.

This product definitely works but they gave me headaches. I'm sensitive to headaches already though. The energy was moderate and not jittery. Didn't make me crash either. I usually took 1 a day. Worth the purchase. Small pills, easy to swallow.

I like these I’ve tried to cut back on energy drinks but still need caffeine these seem to work pretty good. I only take one I. The morning before work and it gets me through I would buy these again. Did not notice jittery was or any side effects.
