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

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.

Very effective.

I really like these. Ever since I stopped drinking coffee I need a wake me up in the morning and this is perfect. Doesn't leave me jittery mid day if I don't eat in time. Best thing is it feels non-habit forming because I don't get a headache on days I don't take it.

This is my second order of Vivarin caffeine pills. I use them irregularly, mostly in the morning when I'm in a hurry somewhere, or keep them on hand for long days of work. I've already almost gotten through the first box and just received the second. They are pretty much tasteless and I notice a stimulant effect after about 30 minutes. The effect gives me a focused, energetic, and productive mood, and personally lasts for about 3-4 hours, but I'm particularly caffeine sensitive and only take 1 per day. For the price, you definitely cannot beat it. By far the best caffeine supplement that I've ever purchased.

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.

I take just one. No only do they NOT give me the jitters but they are just enough to last at least 6 hours. I have a 15m old boy and these are non habit forming and don’t give me a headache if I don’t take them. I highly recommend, Congo you have a customer for life!

Great option when you need a pick me up! It's a nice option rather than coffee or the calories of a soda. I have used for many years for my tennis matches as well as keeping a few in my purse for other times. I do not feel jittery and I am quite sensitive to stimulants. Highly recommend!

Works amazing for my son. Keeps him focused and awake as soon as he gets to school. He is 8 & takes half a pill/day.no sugar. No other meds! He is in 3rd grade. Teachers have seen a big positive change.

Works well & as expected.

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