The 50mg Caffeine/100 L-Theanine is the best energy boosting supplement I've found. I've tried straight Caffeine and I get too jittery, the L-Theanine is necessary. I've also tried 100mg Caffeine/200 mg L-Theanine and, sometimes, it's just too much. With the 50mg/100mg combo I can get just a little boost or, if I really need it, take a couple. It allows me to get the right amount of caffeine without becoming over caffeinated. Perfect Caffeine Supplement!

Perfect product for my system. Amount of caffeine is just right and there's no huge jolt...it's a nice, level effect. Customer service at VALI is excellent. I was in contact with them regarding their free bottle offer and they were friendly and helpful.

I like that they’re lower at 50mg, so I can have lower doses the days I don’t need that much caffeine

Drinking a tea or coffee is fun, but not always practical and it’s great to keep these on hand for a quick dose of caffeine. Love the size too, so I can decide exactly how much I want each time.

Have Hypnic headaches, which wake me up every night between 2-3. No meds worked. Search on internet said to drink caffeine before bed, but only 40-50 . Coffee has 200, and I would be up and down going to the restroom half the night.
I take one of your caffeine pills and no headache! Thank you!

I work night shifts, it have been a blessing using Caffeine & L-Theanine pills.

Great product, I like how I can regulate the amounts or intervals of caffeine I use during the day.
