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.

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

Prolab's caffeine tablets are the best. But, recently their price increased almost 100% so I looked for a replacement. I picked these up. One, this brand is only 100 mg, whereas the Prolab tabs are 200 mg. I tried them for a week, each morning I'd wake up with a monster headache. The headache would last all freaking day, non-stop. I paid the extra cost for the Prolab tablets and headaches are gone. THANK GOD. Buy these if you want a super headache. Hope this helps.

I'm taking caffeine capsules/tablets about 5 years and tried many different brand, but first time saw such thing. Inside capsule is 500mg powder, but should be 100mg caffeine, what is extra 400mg, or is there more caffeine with filler, I dont know, I emailed Nutricost, but no response, so take care...

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.
