4-in-1 Focus Booster | 200mg Extended Release Caffeine Pills with L-Theanine + Lion's Mane Mushroom for Productivity, Energy, and Memory | Natural Caffeine + No Crash | 60 Focus Pills | Made in USA

I recently tried an extended release caffeine supplement, and it’s been a game-changer for my daily routine. Unlike traditional caffeine pills or coffee, which can cause a quick spike and inevitable crash, this supplement delivers a steady, sustained energy boost that lasts for hours.The dose is perfectly balanced—enough to keep me alert and focused without the jitters or heart-pounding intensity of energy drinks. I take it in the morning, and it carries me through my workday with consistent mental clarity, whether I’m tackling meetings or deep-diving into projects. The extended release formula truly lives up to its promise, providing smooth energy without the rollercoaster effect.I will use this product for the foreseeable future

I wasn’t sure what to expect from this blend at first, but it’s quickly become my go-to on days when I need to lock in and stay productive. The extended-release caffeine gives a clean, steady lift that feels far more even than your typical cup of coffee. It kicks in gradually and doesn’t come with the shaky, overstimulated feeling that some high-caffeine supplements tend to cause. The inclusion of L-Theanine definitely helps round things out with a calmer, more focused energy that actually feels sustainable, not like a spike-and-crash situation.One of the standout ingredients here is the Lion’s Mane mushroom. I’ve used it in the past on its own for brain support, but combined with the other elements, it seems to really elevate my concentration and mental clarity—especially during long blocks of work. It’s subtle, but I noticed I wasn’t zoning out or reaching for distractions nearly as much. I also appreciated that there wasn’t any weird aftertaste, no stomach upset, and the capsules are easy to take with water. It's unflavored, so there's nothing lingering after the fact, which I personally prefer.If I had to nitpick, I’d say the biggest trade-off is that this kind of clean energy boost might not be “enough” for someone who’s chasing a jolt or used to heavy stimulants. This is more of a smart, functional energy than a dramatic one. But that’s exactly why I like it—it does the job without the downsides. For the price, ingredient quality, and overall effect, it’s a great value. Definitely something I’ll keep stocked in my desk drawer.

The extended Release Caffeine works quite well. I normally crash in the afternoon after coffee, but can already see a difference after using. The focus ingredients+Extended release caffeine work well together.If you are more tolerant to caffeine, can take 3 for more of a hit.

I had high hopes for this nootropic supplement based on the description, but unfortunately it didn’t deliver for me. Compared to other nootropics I've used, I didn’t feel any noticeable increase in focus, energy, or alertness throughout the day.I do appreciate that the ingredients are natural and the formula is clean with no jitters or crash, but overall, it just didn’t provide the boost I was looking for. It might work differently for others, but for me, it fell short.

Took yesterday morning and felt energized and less brain fog. Definitely helped me be more productive during the day.

I know I have a high tolerance to caffeine, but these did give me a little boost.I took two on an empty stomach about a half hour after I first woke up, and within about 30 minutes or so I did feel as though I had a small cup of coffee.Normally I have coffee when I wake up, but I usually use either a french press, or slowly make pour-over.My cup is usually a 32oz mason jar, for reference.I tried to refrain from making and drinking any coffee for as long as possible to gauge how well these work, and I was able to make it a few hours before I really needed a nice strong cuppa.These would probably work much better on someone with a weaker/normal caffeine tolerance, but for me they were equal to a 4-8oz cup of drip.No unwanted side effects, and I like the concept, just not strong enough for me, but your mileage may vary.

It clears up brain fog and provides enough energy for the day. It has fully replaced my need for coffee or an energy drink!

These seem to contain what they advertise - the pills are easy to swallow without an obvious taste, and they provide the supplements that are purported to help with focus energy and memory. Here's hoping for longterm effects!
