Nutricost Caffeine Capsules 100mg, 500 Capsules - Non-GMO, Gluten Free Supplement

I thought this was a bottle of 200mg caffeine pills, but I just realized they're only 100mg. Oh well.... there are 500 of them, so even having 3-5 at a time- with 4 of them being equal to my morning dose of 400mg- the bottle should last a good 2-3 months. The quality is 100% sufficient "unto the cause". At least, I assume it is, based on the 200mg version of the same brand. I haven't actually opened this 100mg, 500ct. bottle yet. But, like I said, if the quality of the 200mg capsules are any indication, the 100mg ones will be good as well.

Good way get caffeine without making coffee i am sure someone will cry about it there's always one lol

Better and faster working than othe caffeine.

This is very helpful when you suffer from headaches and need caffeine to assist but don't want to take it in a different form. I am happy with this product.

27yo female, been using these since college whenever I didn't want (or my stomach didn't appreciate) extra coffee but still wanted the caffeine. Works well, no other issues or effects! I also like that you can open the capsules, so that if you wanted, you could pour out a little of the caffeine powder for a lower dose.

These are great to take with ibuprofen for tension headaches. I would prefer tablets over capsules, though, because sometimes I only need 50mg.

They aren't as good as Nodoz

These do not work. I feel nothing even though I am pregnant and more sensitive with a low tolerance.

I tried these for a couple of weeks. I can usually take 100 mg caffeine tablets and they will keep me awake all afternoon, but these seemed to have no effect whatsoever! I took up to 4 some days and still nothing. Is there any caffeine at all in these? I ordered another brand and the new ones work fine. I don't recommend these at all.

I'm sorry but this stuff is nasty it left me feeling like I was poisoned I'm not exaggerating at all I'm a truck driver and I start getting tired towards the end of the day so I figured I'd take a couple of these to get through the day the crash from these are so bad I didn't even eat dinner or nothing I went straight to bed last night and felt like I was poisoned all night long and I still feel like I would've been poisoned, in the course of the day i think i took like 8 but nothing was happining,now today i read on the bottle never take more than 2 in one day? if you do call poison control? GREAT!!! end game? THEY DONT WORK,AND CAN KILL YOU!
