Nutricost Caffeine Pills 100mg Per Serving, 250 Capsules

This is not good (no, really). This is a bad unsafe product. I put it as 5 star review so it would not be hidden. I don't know if this is actually caffeine, or other stuff. Was around 600mg from energy drinks. Acidity was affecting my teeth. Switched to these. Wasn't pushing as much, but was feeling pain in my kidneys from lower amounts like around 300mg and maybe less. Reluctant to take these pills. Push to 600mg and felt pain. It wasn't good. Chilled out, let my body recover. Was using these pills for maybe 2 months. Switched back to energy drinks. Oh my gosh, just 200 mg from a Celsius gave me such a good jolt. THESE PILLS MADE ME SO EMOTIONALLY NUMB. Already I have such a serious personality, but these pills made me so unable to actually feel emotions, even with things I actually liked. I remember having that Celsius and thinking 'what is this feeling?' Emotions! That's what I felt. Emotions. Before these pills, I was on energy drinks 600mg daily. Stopped cause acidity. I went into caffeine withdrawal. Was so sick, cold, sweat so much, felt so terrible for 4 days. Was great after. Not so much later, I wanted caffeine again (cause it's so boring). Switched to these pills. Terrible. Did not experience that energy or stimulation of caffeine, but some type of feeling of emotional numbness. No alertness. No perked up energy. I never went into withdrawal when taking these pills, so something is in it, but what? I didn't ever feel a kick like you'd even get from 1 coffee, cause even though you might have a high tolerance, you can still feel a coffee. With these pills, you don't feel anything, not even pushing to higher amounts. All I felt was such emotional numbness and kidney pain even from lower amounts. Days later, energy drinks, 600mg in 24 hour period (12hour consumption time of 600mg in 24 hour period), did this a couple days in a row. No kidney pain. No emotional numbness. These pills are dangerous. Look at the 1 star reviews also. Do not buy these.

I have bought these multiple times. This brand is the best quality and the best deal for your money. They are easy to swallow and the perfect strength. I like to open the capsules and pour the powder on my tongue and swish it down with some water for faster results; it doesn't taste bad. These give you the extra energy you need without the jitters because they are only 100mg, which is just enough without being too strong. Nutricost is the brand I trust for my supplements because they are consistently of the highest quality for the best price!

SO great! I have been switching from energy drink to these and I am surprised I haven't done this sooner! Don't needthe energy drinks when I got these! Great ingredients, and lasts all day (I do take two but some days I take only one)

I don't like coffee but still need caffeine. So this is my good choice.

Good product at a good price. I have been taking them to stop drinking energy drinks and to cut back on caffeine. I was taking around 800mg of caffine between pre workout and energy drinks a day and now with these I cut back to 400mg a day. I use 1 capsule about every 3 hours.

If some thing makes you sleepy take this if you're not a coffee drinker or it's not available.

Bought the 100's to gauge the dosage. Two does the trick.

I've had plenty of high quality supplements and unfortunately this isn't one of them, it has not much of an energy effect. Green tea has more..lolNext time I'll get one of the others
