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!

Consistent energy with no crash
Love the 1/2 ratio of caffeine to L-Theanine. Consistent energy with ability to focus. I seem to have no crash or jitters throughout the day which is nice! Plus they use clean ingredients with regard to the capsule itself. No silica / silicon dioxide which although in small amounts is deemed safe, I care about what I put into my body and Sports Research seems to think the same way with their products.

The big yellow pill that works!!!
I absolutely love the Sports Research L-Theanine Supplement with Caffeine & Coconut MCT Oil! This powerful combination of 200mg L-Theanine and 100mg organic caffeine gives me the perfect balance of focused energy and relaxation without any jitters or drowsiness. I feel more alert and productive throughout the day, whether I'm working or exercising. The softgels are easy to take, and I appreciate the quality ingredients. Highly recommend for anyone looking to enhance their focus and energy levels!

Wakes my mind up just enough to function
Taking this LT+Caffeine soft gel daily for about a week. I'll see how it affects me mentally over 3 months, but as for immediate effects, it wakes up my mind enough to feel normal, as opposed to yawning all the time with super low energy. This doesn't give me caffeine boost, but has enough for me to function normally. I take in the morning. My sleep is the same. I will continue to take this version.

A must try !!
I work in collections for subprime lending . Fast paced maddening work and multitasking and dealing with numbers all day . I get burnt out , extreme mental exhaustion , loss of drive and focus , especially on fridays . I take this supplement minus the caffeine version sometimes at bedtime and it knocks me out . I was skeptical of the caffeine version but I did my research . Today is Friday . I took a late lunch , tired , irritable and loss of drive . I had my lunch and took my pill . I got so busy once I clocked back in I forgot I had taken it . At 5pm it dawned on me that I was calm and serene , focused, not hyper or “jacked up “ even the stress in my neck and back was manageable. I truly believe this natural supplement is truly a godsend in my chaos of life that I love . This brand is chefs kiss . Their magnesium tretonate is perfect bedtime supplement . Good quality products that a few trusted educators I follow have recommended. I am not sponsored or paid to give this review but I really really want others to know when I find a great product , because I want to know too !! To many fake influencers out there that will put their name on anything for a buck .

Awesome bump without the crash!
Wasn't sure what to expect, if anything from these, but I've had previous experience with the brand and was pleased so figured why not.These definitely do not disappoint!They give me a clear, clean bump of energy that helps me focus and get in the zone without making me jittery or tweaking like some gas station fix. Perfect for gearing up for a day of office work or a long gaming session with buddies.I use them only on occasion but when I do I feel it without side effects, easy to swallow, no taste and never seem to "crash" afterwards, just a taper off is more like it.Sports Research does it again. Totally Recommend.

Better value elsewhere
Allows me the focus and energy for early morning decisions. Kinda pricey compared to competition.

Best Energy Pill I have Ever Used
Well I finally just took my first pill yesterday morning and it worked very well indeed. I was more awake, alert and energetic all day long! Then as bedtime approached I was beginning to worry if I was going to be able to sleep as this pill was still going strong. But, no worries, once I laid down I started to feel tired like I usually did when I went to bed and off to sleep I went without any problem. I had a good night sleep and actually woke up about a half hour earlier than my alarm clock did. I still feel the same energy and alertness in the morning I felt yesterday. Now, I need to see how long this pill will work for the long run as so many others started to fail to work within a few weeks of use. I'll come back later and report my findings.
