Vivarin Caffeine Alertness Aid 16 count tablets

“I’ve been taking Vivarin pills for a while now, and for me they work as a nice little pick-me-up. They don’t give me a jittery or overwhelming feeling — just a subtle, helpful boost when I need some extra energy. Overall, they’ve been consistently helpful whenever I need that extra push to get through the day.”

This worked great for me... I even skipped my morning coffee (entire pot usually) but I had energy to clean. It made me feel like my eyes were glued open at first! My husband also took it today but he said he couldn't feel it. Maybe because he has mountain dew I'm his veins because it's all he drinks. But I'm happy with it. Well worth the cost to me. I was able to keep focus and felt good

I love my coffee. But sometimes it just isn't as effective as I would like. Or it gives me the jitters or I have to pee too much. This is when I like to use vivarin. I like how it restores clear thoughts and helps me motivate without the coffee side effects. I can feel it kick in quickly. Each pill is stronger than a cup of coffee and 16 pills in the pack for under $3 is cheaper than any coffeeshop. I've used this product for decades. This seller got it to me overnight. Happy customer here.

I have used this brand for decades. Working in a pharmacy, these are a must have just to survive. They kick in within about 10 mins. Beware though, you will need to make some runs to the bathroom lol! But that's normal with anything with this much caffeine. I don't like coffee and I don't drink soda. So these are my go to. I would definitely suggest taking with a full stomach though. I have read a lot of the reviews about the expiration date. I received mine on 01/28/26. My pack doesn't expire until July 2026. So no issues there.

The Vivarin Caffeine Pills do provide an energy boost, but the effect feels different from drinking coffee. Instead of the smooth, alert feeling I usually get from a cup of coffee, these pills made me feel like I took a lower-grade or less effective form of caffeine. They’re convenient for travel or when you don’t have time to brew coffee, but the experience isn’t quite the same. Overall, they work in a pinch, but I probably wouldn’t use them as my main caffeine source.

I swear by these pills. They will make you jittery if taken on an empty stomach. But has no taste and really helps me when I need that boost of energy. I have bought about 4 packages and will continue to buy them.

Known brand. Worked as promised. No stomach upset. No jitters. No bitter taste.

I've used bunch of different brands with caffeine pills and me and my wife get the biggest boost out of these you can feel the difference
