Vivarin, Caffeine Pills, 200mg Caffeine per Dose, Safely and Effectively Helps You Stay Awake, No Sugar, Calories or Hidden Ingredients, Energy Supplement, 40 Tablets

Good little caffeine pill. Actually was surprised they still made these as they have been around for years. I like that they don't cause any jitters. you actually do feel more alert and awake with just one pill but I don't feel like they would cause me not to be able to sleep should I take them too late.

Product good. I've always used these instead if coffee. For me, no jitters, but there is a crash once im tired.However, the seller is awful at following instructions. Maybe Amazon is packaging this up or it's being packed elsewhere, but I was promised next-day delivery multiple times and still have not received my order. Very annoying.

This caffeine supplement is amazing. I’ve been drinking coffee and highly caffeinated tea for years. I never liked the taste. No matter how much I doctored up my coffee, the aftertaste was horrible. I like that I don’t have to use the bathroom excessively after I take this pill. It’s easy to swallow and works within 20 minutes. I have never had trouble falling asleep after it. But I never take it after 2:30. I usually only need one a day. Very cheap especially when compared to the cost of coffee. I have had no adverse effects

This product works! I don’t need to drink coffee or sodas for a boost of energy.

Good product, if in need of a boost. Im not a coffee drinker & this helps keep me alert. I break in half usually. & take other half later. Wouldn't take past 4 or 5 pm tho.

They work! Don't need to buy expensive energy drinks. Just had a baby and having to stay up at night and having to get up to go work early in the morning has sucked! These have help quite a bit to keep me alert during the day.

My husband has a condition that when he is very physical, his blood pressure goes down and not up like most people. He has medication for this condition, but the medication takes too long to work. The caffeine pills work within 15 to 20 minutes so I carry them with me wherever we go. It has been a "lifesaver". There have been times when he walks up stairs and needs to put his head down because he is dizzy due to his blood pressure plummeting. These are much better than drinking coffee every time there is a problem. My only complaint is the expiration dates. I have barely 6 months to use this. I wish they would send me fresher stock and not what was forgotten on the back of the shelf.

I like how it is a heavy coated pill, potentially safer on the stomach. I wish they would offer a 100mg pill. I also was disappointed that it says made in USA, while the package I received says made in India.
