  • My Go-To for Focused, Jitter-Free Energy — Been Using It for Years
I’ve been taking Sports Research L-Caffeine and L-Theanine for a couple of years now, and honestly, I don’t know how I managed my workday before finding this supplement. I work full-time in an office setting — lots of screens, constant emails, and the kind of mental fatigue that can really drag you down by mid-afternoon. I used drink a ton of energy drinks, but the spikes and crashes weren’t sustainable and made me feel wirey in a way that wasn't good long term. This supplement has completely changed that for me. Clean, calm energy is really the best way to describe it. Each capsule gives me a smooth, steady lift in energy and alertness, without any of the jittery or anxious side effects I’ve gotten from energy drinks. It kicks in gently, I'd say, after about 20 to 30 minutes and helps me stay sharp and productive for hours. There's no hard crash — just a natural taper back to baseline. What keeps me coming back to this product is how noticeably it improves my focus. Whether I’m diving into a spreadsheet, writing reports, or sitting through long meetings, I feel more dialed-in and mentally clear. Answers (most of the time right ones, ha!) come easy. It doesn’t feel like an artificial boost — just a better-functioning version of myself. The capsules are also incredibly easy to take. They’re small, smooth, and I’ve never had an issue with digestion, aftertaste, or lingering effects. That alone makes them easy to stick with daily with vitamin D supplement or magnesium. On top of that, I really appreciate the quality and transparency that Sports Research provides. The ingredients are clean, clearly labeled, and third-party tested. The product is vegan, non-GMO, and thoughtfully packaged — all things I’ve come to value after sticking with it for this long. Honestly, I like that it's not agro on the packaging. As an aside, I'm gonna take a leap and guess that the quality of the ingredients SR uses avoids any acrid smell. If you’re looking for something that supports real focus and mental clarity — without the wired feeling or the crash — this is it. After a couple of years of consistent use, I can confidently say this is one of the few supplements that actually delivers on what it promises. It's not the sort of supplement that will pep you up if you're not already getting adequate amounts of R & R, but it does add to your mental accuity if you need to focus. Highly recommended for anyone who wants to feel clear, calm, and focused throughout the day. One in the AM before work, maybe with a cup of Joe if you need it, and one at lunch is all you need to get the boost you need on a busy day. And at this price point, it's a pretty good return on investment. PS: they also produce a really good fish oil supplement, too! ... show more

  • Menopause SUCKS and sucks less by taking these.
This supplement has become an important part of my menopause health routine, and I can honestly say it’s been a game changer for my energy, focus, and overall well-being. The combination of L-Theanine, caffeine, and MCT oil provides a calm, steady boost without the jitters you get from coffee alone. A little advice... take these in the morning, not at night. They give you a clean, balanced energy that lasts throughout the day and helps you stay focused without crashing later on. I always keep an extra bottle on hand, thanks to my husband, just in case they sell out... that’s how much I rely on them. As with any supplement, I highly recommend doing your own research before starting. For me, these have been an excellent addition to my daily routine and have made a noticeable difference in my mood and energy levels. ... show more

  • Keeps me awake at work
Good quality, fast shipping. Helps with brain fog, without making me jittery

  • Lasts a little bit too long
I work a 12-hour night shift, and I am trying to avoid others sources of caffeine or chemicals to keep me awake and alert at night. I decided to give these a try because they have 200 mg of caffeine and L-Arginine. This tablet is a little bit large but is coated well and is easy to swallow. It also does keep you up all night. I have used it a few times and I prefer to take it before work, it does not give me jitters or the dump that straight caffeine gives you. You. However, I have noticed, according to my sleep score, that when I use this product I do not get enough REM sleep. Sleep. That is not a good thing, so I use it for the first day or so at work and then I don't use it for the rest of the week. Unfortunately, I find that when I do use this product I have a hard time going to sleep when I get home. I'm not sure that this is such a good idea for regular to use, but for us work shift where I did not get enough sleep. I will use this but not regularly anymore. As REM sleep is very important! ... show more

  • Great Boost
I need my caffeine. Highly recommend for students/bar exam takers/attorneys. I bought this as a supplement for my coffee for the bar exam (and also used it during studying for the bar). I knew that I did not need any extra diuretic properties from coffee during the exam. This had less caffeine than my typical coffee, yet it made me more alert and able to focus than coffee. I assume it's a result of the L-Theanine. Seems to be high quality--friends who also had caffeine pills with twice as much caffeine reported that they felt more alert with this. Zero taste or smell, and relatively easy to swallow -- it is a relatively large soft gel. Now I keep them on hand for when I have to skip coffee for whatever reason or need an extra boost to get past the afternoon slump. ... show more

Gives the kick you need and does not cause jitters.

  • Doesn't do anything to me. I feel it is simply being digested and ineffective.
I really wanted to like this product from this brand, but it simply doesn't do anything. I don't feel any different. It was a waste of money for me. However, the brand Zhou's Energy + Focus Pills has been absolutely awesome. I feel the clarity, focus and gentle energy rise without any caffeine jitters with pills from Zhou. ... show more

  • Great source of caffeine
I've replaced my slow release Ritalin with this and daily meditation. No jitters (I'm sensitive to any stimulant, including different types of caffeine). Awesome product overall... I'm subscribing to this product, I like it so much.
