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 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.

UPDATE - after more research; I am not going to try this type of caffeine. Found other TRUE reviewers who say it does cause jitters, nervousness and is too strong. Very hard to get the truth about what type of no jitters caffeine is in soda, 'cola drinks'. So; I am going to try to drink only homemade cocoa and water. I love the type of caffeine (probably synthetic?) that is in diet colas. Does not give the jitters, nervousness and other health problems that coffee, tea cause. But; not one soda company will develop a 100% sweetener free cola! All have that toxic aspartame, or asfultame potassium, or that unhealthy stevia.., or sugar, fructose. So; I been doing research and trying to find the type of caffeine in colas so I can make my own drink with this type of caffeine. Very hard to find the TRUTH!! I do not know if this Anhydrous caffeine is the same chemical type of caffeine in colas. Called 2 major soda companies and they refuse to tell the type of caffeine. I heard its synthetic and made in dangerous chemical factories in China. Truth is hidden. They rule the internet, hiding the formula. I am afraid to try this Anhydrous type, but if I get the courage up and do it; will post a review update. 3 stars because I have not created my own drink from it yet to test it. Will start with a small 16th or less of 1 capsule. Or more healthy drink; chocolate in baking powdered cocoa by grocery store brands. They usually are sulfite... free, pure. Not as energetic as other types of caffeine, but is healthy. Lady friend lived to 104 years on cocoa.

I'm using these to test some home made skin care products, so the volume is important ... and why I measured the amount. As it turns out each capsule is very nearly, perfectly 200mg, which makes things easy. I was going to buy caffeine pills locally but it's actually kind of hard to find *JUST* caffeine powder (unless you buy bulk, online). Anyways, really nice that this is available. Seems very high quality and accurate.

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).

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.
