VALI Time Release Caffeine 100mg Pills - Smart Slow Release for Extended Energy & Focus. Advanced Nootropic Supplement. Brain Booster for Active Performance, Alertness & Clarity. 120 Veggie Capsules

Great product! I’ve been using it for several years now and I have always been happy with the consistency of the effect and quality. It gives me the energy and mind clarity that is expected from caffeine in a slow and steady way without any side effects on my heart or stomach! I love it!

I have taken only one capsule, but I have NOT had any adverse reactions. It seems to be working as advertised. I have NOT felt any jitters, nor any feeling of being short tempered as compared to a plain 100MG caffeine pill which causes my heart to flutter accessions. I am excited about finding this product.

Quality product. Just great.

This time-released caffeine pill seems to work as intended. It gives you a longer duration effect of five or six hours (as opposed to three to four hours for regular caffeine pills) and a lower jolt to your system since it releases gradually. I thought this would be useful to me because I don't really like the feeling I get when I use caffeine. Caffeine is good for keeping me awake during my afternoon slumps, but it also makes me feel tense. So I tried this time-released version since I thought I could avoid a spike and thereby reduce my reaction (tenseness) to it.However, I still wound up feeling just as tense; except now it was for a longer period of time. So I have discontinued using this product in favor of regular caffeine pills (Jet Alert). The regular caffeine pills are fast acting and they don't stay in my system as long, maybe four hours or so. I still get the tense feeling, but it reduces the length of time it lasts. I only need the stimulant effects for maybe three hours to avoid my afternoon slumps.So this time-release version may work better for others than it does for me, if you want a longer and more gradual stimulant effect.

Absolutely love the smooth and long lasting effects of this caffeine! No jitteriness!

My husband's neurologist advised we use only caffeine, initially, in an attempt to stem his excessive drowsiness/sleeping. I started with stronger coffee, but he wouldn't drink anymore than his usual morning amount. That's why I ordered these. I have used the limit (4 in 24 hours). Unfortunately, they have not helped. He has dementia, possibly "mixed", & an olfactory fossa meningioma. For others, this product might be the best way to go - for us, it wasn't.

very good for an afternoon boost. long lasting and no jitters. only 100mg of caffeine so does not affect my sleep at night.

Not for everyone. I experienced a sudden rush for the first hour with my heart pounding faster and I was feeling jittery. I thought I would get a heart attack. After an hour I crashed and was feeling sleepy and drousy like I never did before and it was 9 in the morning with my work time ruined. It is not time released as they promised as it was all released instantly. Waste of $19 and time.UPDATE: I tried with other remaining tablets and got the same results. I believe there's a manufacturing defect with the capsule shell as it gets disolved easily. The entire barch should be recalled by the manufacturer.
