Nutricost Caffeine with L-Theanine, 100mg of Each, 240 Capsules, 240 Servings - Non-GMO and Gluten Free

Worked very good for me. But I crashed badly after so make sure to eat enough food after 3 hours because I crashed after 4 hours later. Important thing, make sure to sleep enough otherwise if you are doing exams, you will feel fully awaken but have bad brain fog.

Very impressed of how I can feel, relaxed and have energy in the same time,100% recommended

Really effective !

These capsules work excellently, exactly as expected. The energy level is what you would expect from a shot of espresso (80-100mg), suggesting the caffeine is well measured and pure but will release and be absorbed quite rapidly in comparison, so exercise caution. Effects of L-theanine are not clearly evident, although this lines up with research findings so don’t worry too much about it. Each capsule is about a centimetre, with the bottle being around 200ml at 10cm tall. Note that the outer casing is made with gelatine and cellulose so is unfortunately unsuitable for vegetarians or vegans, however is very easy to swallow compared to some other products with just a little water. Ensure enough water is used so the capsule doesn’t get stuck or become sticky as this can cause the powder to release prematurely and have a very unpleasant taste. I’d consider this product good value for money, easily a 6 month supply with moderate use. Works perfectly effectively with my only concern being the rapid absorption of caffeine compared to coffee, although this is a good dosage.

Late afternoon or early evening is best, they really helped me focus on studies and also pretty good as a pre-workout tab.

Good but gives massive headaches so do not know if it is product itself or just this L-Theatine effect

This delivers the promised dose of wakefulness and focus. Helps when traveling to reset body clock and keep going.

Used to aid focus for ADHD. Wanted small caffiene doses so this 100mg version is perfect. Use 200mg (2 tablets) per day. 1 in the morning and another at 1pm. Can take any where and tweek as activities allow. Takes about 20 minutes to cut in. A lot cheaper than a coffee or tea as well needing no time. Works for me.

He notado mas energía y agilidad mental en mi día a día,

Parfait j'ai ressenti un boost sans crash grâce à la L-theanine et une sensation focus c'est vraiment un très bon rapport qualité prix je recommande ces compléments les yeux fermés mais tout de même attention a la marche 👍😎

Excelente producto es como 3 tazas de cafe

Honestly 1 a day, the taste is great, because there isn't 1.. the texture is a capsule pill type, it gives me some energy, not much. Tbh, I like them, but I think my hearts pounding alot more with sharp pains. Like I dont take them daily anymore, yet they sure are strong. Focus is legit, duration is breathtaking forever it seems yet the value is great, kinda like amazing. TEXTURE IS A CAP. I saw that in the questions lol.

It’s good quality
