Genius Caffeine - Sustained-Release Microencapsulated Caffeine Pills for Smooth, Long-Lasting Energy & Focus - No Jitters or Crash - 100mg per Capsule - 100 Servings - Natural Performance Booster

My husband isn’t a coffee drinker but wants the pick-up of caffeine to start his day. He’s tried many drinks & pills before finding this one. The drinks were either sugar laden or contained unhealthy artificial sweeteners that he didn’t want. He’s LOVES this brand. The caffeine is time-released- a huge advantage, My husband isn’t a coffee drinker but still appreciates a morning boost of energy. Over the years, he’s tried countless caffeine drinks and pills, but most were loaded with sugar, artificial sweeteners, or caused unpleasant side effects. Then he found this product—and it’s been a complete game changer. The time-released caffeine is its standout feature. It provides a smooth, steady lift with no jittery spike or mid-morning crash. Because the release is gradual, it’s also easy on the stomach—no discomfort at all. The convenience and consistency make it an effortless part of his routine. He’s been using this brand for several years now and has no interest in switching to anything else. It truly delivers clean, reliable energy without compromise.

Really good product; it works as described. I can't drink coffee, so these pills gave me energy.

This stuff is like a holy grail! Keep in mind I am a guy that was doing 400mg of caffeine a day from energy shots to stay awake. These pills are 100mg of sustained caffeine I can take one pill in the morning ing and I am awake and alert all day until I go to sleep at night. Also sleeping better at night. If you are dropping from a high dosage of caffeine like I was be prepared for withdrawal headaches first my eyes were throbbing like a migraine. I took some non aspirin pain releif and it helped after 2 days headaches are gone. I feel so much better alert and focused on this product and you get 100 pills going to last me 3 months. Don’t hesitate on this product also leaves no stomach upset. Genius is a great company now I want to explore what else they offer.

An energy boost without the caffeine crash compared to some supplements. 3 pills, 1 bottle of water, and go.

Caffeine via coffee or normal tablet is too much all at once, and makes me jittery, shaking & anxious. However, I am a pathologically sleepy person, and caffeine is a big part of not napping through half of each day. These are absolutely perfect. I can feel the wakefulness as it comes on, and it is indeed sustained over a longer time than would otherwise be the case. But I don't shake, my heart does not feel as if it's in my throat, I'm not jumpy & awkward--at least, no more than usual. I'm a very big fan. I'm certain I'll repurchase these.

This is a great product for people who are looking for an extended release caffeine. I take 1 pill in the morning and it seems to last 3-4 hours without any crash effect. Helped me when I needed to cut out coffee because the acidity was bothersome.

I’m sensitive to caffeine which is why I only drink g fuel, (slowly throughout the day) but been taking a break because I have high B vitamin levels and trying to drop them down so I got these pills. On the days that these pills did work, it definitely was not “slow release” in my opinion. It hit me like crack lol I guess I thought it would be a light caffeine buzz that lasted throughout the day. No.. I was a super human within 15 minutes lol couldn’t stop me. Then it died down after a few hours but still couldn’t sleep and felt antsy and tired. Then I think maybe I was burnt out after or something cuz for the rest of the week they did nothing but accelerate my heart rate while being tired and not letting me sleep. Do they work? Technically yes kinda. Did they do what I wanted? No.

I bought these because I was trying to reduce my caffeine intake (most caffeine pills seem to be 200mg, which is what I'd been taking previously). I don't really notice whether the effect is long-lasting, but they are smooth--I don't notice a come-up or a crash. They don't impact my sleep negatively. The pills are fine--no bad taste or smell, the size isn't hard to swallow, I just pop 'em with my morning meds and don't even notice. I'll probably keep buying these. I like the other Genius brand products I use, so I'm happy to get my caffeine from them too. I don't know that they're the most economical option for caffeine pills, but they're reasonable enough.

استخدمتها في رمضان مع السحور وساعدتني على تحمل نقص القهوة حتى منتصف النهار

I don’t know what else to say other than the product works as advertised! No sudden jolt of energy, no significant crash, just a few hours of boosted energy. I mainly really like this product because it gives me the same caffeine boost I would normally get from an energy drink, but this is a fraction of the price compared to the number of drinks you’d have to buy to get the same amount of caffeine. It also allows me to drink water instead of an energy drink and saves on calories and sugar.
