Best Naturals Caffeine Maximum Potency 200mg 120 Tablets

I am working 72 hours a week, off course night shift, this tablet are amazing, take 2 tablet and keep me going all night with no any difficulty , very happy with them. Delivery next day, high recommend.

im 90kg male, doing powerlifting based programs, i have bought this as a substitute for preworkout supplements. 400mg (two tab) are more than enough for me, i got kick from it for few hours, think i will maybe lower dosage to 1,5 tab (300mg). its working, good product!

OMG. the taste is awful, like really bad. happily i didn't buy the tablets for their taste but for their effectiveness and on that point they work just fine. just have something ready to take away the taste after you've swallowed one.

These pills contain quite a large amount of caffeine, equivalent say to 2-3 cups of filter coffee. But the reason I use them is that the pills themselves dissolve in the digestive tract relatively slowly. This "slow release" effect has seemed to be a better way to ingest a larger amount of caffeine. I'll explain. Too sharp a spike in the caffeine serum levels can worsen the jittery effect of caffeine. So chugging down a quick double expresso hits your body very fast, the caffeine is already in solution. It's been found in research that caffeine brings the best stimulation with the least anxiety if the doses are smaller over a long period than just one dose taken all at once. I might add that powdered caffeine products are the worst for this, with the added disadvantage that since the most effective dose is sub-gram, you will need micro scales or proper lab spatulas to measure your intake safely. Of course for some people even the couple of minutes taken to prepare strong coffee is time wasted, so that a pill has that advantage too.Note: Amazon included a "flavour" star rating, which seems a bit funny. Put the pill in your mouth, swallow with a drink... no flavour involved.

I used to fall asleep by 7 pm but now I take one caffeine pill a day am a whole new person.. I just hope that the price does not go up due to good feedback as I've seen this happen so many times. Also I must add I used to drink strong coffee and red bull but not anymore now I have them.. fantasticSo had to edit this as 3 days in and am knackered... They are not working like before so will not buy again

Really effective caffeine supplements. They are great to take before a workout in the mornings, or if you had a restless sleep and need to be up and alert early in the mornings. I also drink double strength green tea to help me keep going. I would advise though not to take these supplements after 12pm; they can make it hard for you to sleep; unless you are a night shift person, or if you need to stay awake during the night to finish off last minute paperwork...LOL! They are great value for money too - not too expensive. Affordable and effective!

I think this caffeine tablets are placebo. They don't work at all. I had bought another manufactured caffeine prior and it worked perfectly while this it's not.

As a student nurse we’re expected to work nights. In 3 years I’ve been lucky not to have more than 3 but now I’ve been out on loads and I despise them! I cannot stay awake! So I decided to give these a go and they have absolutely done the job. I take one as I start feeling tired and it really gives me a kick until I go home and get in bed! 10/10 would recommend.
