Vivarin Caffeine Pills 200mg, Energy Supplement, 80 Tablets

Effective. Great for long carries or any type of exhaustion. Keeps you alert without any jitters you might expect from other caffeine options.

Great price, fast shipping. Only one that doesn’t upset my stomach.

provides needed boost without the collapse 4-6 hours later

I have been taking these for years. Great for when you need a little boast of energy. Usually I take one or two pills and I'm good for the whole day.

It did its job

I'd rate it 4/5 on the alertness scale in comparison to other brands I tried. I just take one during the day when I really need to do something that demands alertness. I take it about an hour before the intended activity I must do. The tablet is subjectively big for me & just like any other tablet of that size, I crack it with my teeth & take water with it for easy swallowing. Like I said, that's just how I do it to avoid the feeling of tablets stuck in the esophagus. 80% of the time, I feel awake after taking it an hour. Sometimes you just can't help it that your body really needs to rest no matter what kind of alertness tablet you take once. Although other people might combine an alertness tablet & several energy drinks &/or coffee, I wouldn't recommend it as it will give you very uncomfortable heart palpitations that can lead to serious health problems. If you really can't stay alert for the most part on a habitual basis, I highly recommend you consult a doctor & get your labs done for it could be an underlying medical problem.

Good

Good product for caffeine, I can no longer drink coffee so vivarin is great.
