NutriJa Natural Caffeine 100MG Plus L-Theanine 200MG - 30 capsules | Promotes Energy, Alertness, Concentration & increased attention | Cognitive performance stack- no crash or jitters.

It helped me be more focused in my BIM lecture. And before more productive throughout the day.It eliminates sleep so would recommend taking it 8-12 hours before bed.Also it didn't gave me caffeine crash.One good thing is also that it is GMO free.I tried caffeine before but since this one has l theanine it works really great.I have bought this product before and have been taking it since 22 days or so and have seen no side effects.It is safe . Just don't take 2 pills at ones.

It’s very effective when you need that extra dose of mental clarity and alertness. It really helps cut through brain fog during intense work sessions.However, I noticed some side effects that didn’t sit well with me, felt jittery, and on some days, I’d situp and felt like like the room was spinning, with a racing heart rate. It might just be that caffeine doesn’t suit me, even with the calming effect of L-theanine.Would recommend trying it with caution, especially if you’re sensitive to stimulants.

Working from home means I need all the help I can get to stay focused and productive. I decided to try out these caffeine-L-theanine tablets to see if they could give me an edge.Honestly, I was pleasantly surprised. Taking these tablets in the morning really helped me feel more alert and clear-headed without the jitters you sometimes get from just caffeine. It was like having a cup of coffee, but smoother and longer-lasting.Throughout the day, I noticed I could concentrate better during my work sessions. There wasn't a sudden crash like with coffee; instead, I felt more consistent energy. That was a big plus for me because I hate that midday slump.I also didn't have any weird side effects, like a racing heart or trouble sleeping, which can happen with regular caffeine pills.

If Suffering from insane amount lack of focus,Great for people with brain fog and reduced alertness in the morning or any time of the day. Keeping me alert and awake. Great product will 100% recommend

I mean it works but some side effects on people

I purchased it with high hope...my primary reason is study...but guys I think there is hardly any effect on my body ....so for me it is total waste

All the benefits of caffeine with none of the side effects. Might upset stomach, but it depends on the person.

I have been using Nutrija Products for a long time now, and I can say with experience that they are Authentic and Effective. They improved my health a lot and gave me the results I desired. They are easy to swallow, and they certainly help in pain relief, if they are meant for that purpose. Just to name a few products that I have used so far - ALA, Acetyl L Carnitine, P5P, L Theanine, Caffeine + L Theanine and some others.They are truly amazing and I have become a fan of this company.
