NutraBio - Caffeine Pills - 100% Pure Caffeine Anhydrous - Energy Support - Increase Focus - 150 Capsules, 200mg

This is a great product with a great price! I will definitely buy again when I run out. I have ADD and a REM sleep cycle disorder both of which I take medicine for but when I feel like I need a boost during the day this product works really well. I'm not a big coffee drinker or tea drinker - an occasional cup of either but the NutraBio Caffeine is so much easier than drinking coffee when I'm not up for it.The capsules are really small - if you're familiar with caps sizes - they come in sizes 000 - 5 with 000 being the largest at just under an inch in length, and a 5 being just over not quite 0.8 inches in length. (Then there are larger medical/industrial, but I don't think we need to go there.)Anyway, the NutraBio capsules are a size 4 so they're very small and easy to swallow.There's no taste to the capsules and no aftertaste or lingering aftertaste.All in all, this is an excellent product that exceeded my expectations.Highly recommended for those who are able to take caffeine.

To the people saying these are sugar pills. Yall probably just crackheads because It is 100% not true. I have a pretty heavy reliance on caffeine. 200mg in the morning or I will consistently get a headache within 2 hours of being awake. I pop one of these and im on my way. No headache and i got some pep in my step. These are reliably 200mg of caffeine anhydrous

I’m a big a coffee drinker during the summer when I am working. For some reason about a two weeks ago I randomly could not take the taste of coffee. I think it’s because I was just drinking so much of it to keep me up during the day that I had over drank it. I was up to 5-6 coffees where I wasn’t even enjoying drinking it but needed that much to give me a boost. I needed to find an alternative and energy drinks were out of the questions. I had a friend who use to take caffeine capselses before hockey. I was hesitant at first ordering them because I felt odd taking a pill for it but also didn’t know if they’d really work due to my tollerence. However they worked awesome! I only need to take one or two a day. Depending on how my sleep was the night before. One in the morning and one sometimes in the middle of the day. Absolutely recommend and the best part is no more coffee breath or stained teeth !!

I use it to (Cautiously!) boost the efficiency of my Rx meds for pain, usually able to reduce dose of the Rx stuff.Some History Trivia: Although involving a BIG DIFFERENCE of ingredients (like: "Morphea" and a primitive Amphetamine), combining the 2 was rumored to be highly effective for severe pain treatment, medically published (very limited distribution back then, like letters to colleagues, perhaps lectures, etc.) IN 1896! (There wasn't a great follow-up back then as to who may have DIED from this Combo!)A bit later, a similar, "cleaner" version of this treatment approach was extensively used during and after WW1, for the HORRID BURN AND GASSING Victims from the battlefields of Europe, nicknamed "The Brompton Cocktail" after a Hospital in London heavily involved in the catastrophic injuries of our brand New "Modern Warfare" in the 1920's, The heavy Med Combos continued through WW2, but became more "civilized" in last 1/2 20th Century (ex: Fiorinal#3, etc).

I bought these because I don't like the taste of coffee without lots of sugar and cream. I hate coffee but I love caffeine. Honestly 1 capsule of this doesn't beat a mug of coffee, but it does help to snap out drowsiness during my morning. I like that it doesn't have any fillers and it's only caffeine, also the pills are very small, that's what make me go for this brand over the others. Next time I'll try a different brand tho, because these were not as potent as expected. Haven't tried more than 1 at a time, maybe that would do the trick.

I use these while intermittent fasting. I have a strong tolerance to caffeine but feel like a whole one is too strong on an empty/fasting stomach. So I kind of rip the top off and dump about 1/3 out then swallow it with water. It’s definitely enough caffeine and I’m good to go. It’s my favorite caffeine pill I have tried. I like that I can control the amount as it feels safer for me.

I used a different brand for years, then bought this brand instead on a whim and now it is my go-to brand. The price is lower per pill, the quality is high, and the capsules are smaller than average, so easier to swallow. All in all, a great buy. I will continue to repurchase. I use these when I don't have access to coffee or tea, or just don't have time to stop for a cup.

Most unfortunately, I have to agree with the reviews that say these have no effect. I had been taking another brand of green-tea derived caffeine (currently sold out), and they were dynamite. These seem to have no effect whatsoever. This is a good and reliable company that manufactures its own supplements and these have no excipients (stearate) in them, which is great. Except that they don’t work.
