NutraKey Caffine 200mg, 100 Count

Some caffeine makes me sleepy, this was great clean energy, not jitters

first time I have tried this brand of caffeine, and it is very good. I feel the energy rush which I started to not feel with the last brand of caffeine I bought. I will be getting more of this brand.

Combined with yohimbine, cayenne pepper, and salt. I had great energy and was able to push through my grueling power day.

I am no stranger to caffeine supplements. Sometimes I just don't have the time to brew a cup or two to get me up when I'm feeling down. After years of using a very inexpensive and more well-known brand, I'd become accustomed to the boost of energy that would follow 15-25 minutes after ingestion. These? Nada. Nothing. I took one before my morning workout as I do with my usual brand. I felt nothing. So, I took another... Still nothing... So against reason and logic I decided to take a third. Wait.. I feel something... Oh, it feels like I took one of the yellow 200mg tablets of my standard cheaper brand. These may work for you but I actually fell asleep in the middle of the day today, 30 minutes after taking two of these. I haven't taken a nap since I was a baby! Instead of pumping me up to workout, it actually put me to sleep. Like an idiot I bought these before my old bottle was empty so now it's too late to return them. Maybe it's my physiology or maybe some of these reviewers have an extremely low caffeine tolerance. Find the yellow tablets. Not capsules. The packaging looks old-school. They're inexpensive. They work exceptionally well. I would not recommend these. I gave them 2 stars because I do believe that they contain caffeine. Maybe 75mg a pill?

Nutrakey Caffeine was bought by me as a last second replacement for my 'usual' which was unavailable at the time. Though somewhat leery of caps (who knows what 'stretchers' can be used in these) I found the claim of 200 mg a cap had to be pretty accurate as one cap was equal to the same 'zing' from a cup and a half (12oz fluid) of coffee and thats what I expect when I buy and use these. Also I buy these in bulk for discount shipping anyway and because I just don't make coffee nearly as much as when I was in my 30's so I substitute three of these over the day instead of the hot cup of 'joe' unless it's the winter months because it goes to work much faster in the liquid state and I'll invite whomever is doing the shoveling for a quick warm up cup then as well. So a pleasant optional purchase which can be relied on for fast shipping, decent bulk discount, and works as described, overall, well done indeed sincerely ~Mark!

I been using this for years my energy level Is awesome I work 12hrs nite shift I love it

Package was different than picture but still the same thing as advertised. Definitely would start off with one instead of two if you were thinking of two (I have a high tolerance but got dizzy right away with two) Also definitely increased metabolism fast, bottle states it helps increase metabolism and it definitely made me want to eat alll day. Kept me awake though like I was hoping without coffee or anything

Great value for the money. Each pill has 200mg of caffeine and nothing else. They are small gel caps and so they are easy to swallow. You can really feel the energy.

I Have Tried Pre Workout Supps,Black Coffee,Vitamin B Complex For Extended Energy ,Its By Far The Best Among All Of It,Am On My 3rd Bottle Now,Caffeine Powder N pills Are Around For Some Time,But Its Pure Grade Potency Could Be Actually Felt Rather Than The Placebo Effect.No Caffeine Crash, Instant Result.See To It That You Do Not Exceed 3 Caps A Day Or Combine It With Any Other Source OF Caffine, Might Get jittery Or Anxious.

Used this for the first time and have found the results good. The only problem is it take very long time to deliver not like other amazon products..

not used , after open notice that internal seal is open from one side ,

前に購入したものが錠剤で苦かったのだがこれはカプセルで飲みやすく粉もちらないので良いと思います。
