Surprising
I’m not even joking the first day of using this, I finished a week worth of tasks downside is that it’s makes it really hard to sleep it’s like you still want to do work even though your body is tired. Overall good product.

Rating: 2.5 out of 5 stars I was interested in this L-Theanine & Caffeine supplement for its potential to boost focus and energy without the jitters. While I noticed some positive effects, a few factors held me back from giving it a higher rating. Pros: Smoother energy: I did experience a less jittery energy boost compared to coffee alone. The L-theanine seems to take the edge off caffeine. Keto & Non-GMO: Appealing to those following specific diets and lifestyles. Cons: Dosage: It might be under-dosed for some. I didn't notice a strong focus effect in just one softgel. MCT Oil: Those sensitive to coconut products or on strict keto might need to consider this ingredient. Pricey: There may be more cost-effective options for getting L-theanine and caffeine. Overall: This supplement shows promise, but it wasn't quite the perfect fit for me. The concept of balanced energy is great, but the dosage, inclusion of MCT oil, and price point all left me slightly underwhelmed.

These vitamins are amazing! I love the way they make me feel so good! Since adding to my routine, I have watched my weight drop into numbers I have been trying to hit for years. It’s not magical but helps a lot. I usually take it as soon as I wake up with a large glass of water. Go to work, go to the gym 3x a week after work, and sleep well and I have the energy to do it! Clean, no crash! I feel superhuman! lol 😆

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!
