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

These are a life saver. They work really fast and keep me alert and ready to get things done. Works better than having to drink a whole cup of coffee.

Works like coffee without the bad breath and you dont crash on these. For all the hard workers. 😁

These work very well but will make you need to use the restroom #1 a lot. Drink lots of water but they do work well. Small easy to swallow its caffeine so focusing will vary.

These don’t give me jitters and help me cut back on expensive espresso addiction. What’s not to love?

These work as expected. The dosage is perfect for me at 200 mg of caffeine. I like that they work much faster and are more convenient than drinking coffee or energy drinks, not to mention, it is cheaper. The pills are easy to swallow. No side effects. I like that the pills came in blister packs and not a bottle because it fits more easily into my bag to have with me on the go if needed. Update: Unfortunately, I have to change my review to 4 stars because I noticed after taking this several times on an empty stomach that I became very nauseous within 30 minutes of taking the pill, and the nausea lasted for several hours which defeated the purpose of taking this to help me with energy and focus when I’m on the go and may not have time to stop and get food to take with it. I did not end up finishing my last pack of these for this reason. Instead I found a caffeinated pre-workout powder that I can carry in my bag which hasn’t given me any nausea or other side effects. I saw other reviewers have reported the same issue with nausea after taking this product, so if you tend to have a sensitive stomach be aware that this is a potential side effect.

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

Several years ago, my mom introduced me to these caffeine pills. I'm not naturally a morning person and often feel sluggish early in the day. These pills have become a reliable source of steady energy, providing a noticeable boost that lasts for hours without the jitters or crashes associated with other stimulants, as long as I follow the recommended dose. Whether you need to get through a long day of school or work, or stay alert during an overnight study or late-night event, these caffeine pills can help you remain focused and energized.

GOOD OLD PRODUCT .

Works well & as expected.

They won’t make you James Bond but they could make you Roger Moore!!

Très peu d'occasion mais quand j'en ai besoin ça fait le travail !
