It boosts my energy, I feel very focused for 2-3 hours, afterwards it starts declining. But no jitters, or side effects on my side. Recommend natural focus booster. Probably better not to take coffee during this time, unless you have low blood pressure and you want extra edge :-) Please like this review if you liked it 👍
Bought for my husband. His age is 44. He reported that he is slightly alert at work especially during early mornings. He has not tried taking them after lunch though. So far only one dose before work. Not bad quality but pill is rather large size to swallow. Will see how it goes.
If you haven't tried Guarana.... it's a game changer. I've been using it to supplement my other vitamins for about 2 years and within a week, the contribution towards not only my energy levels but my overall optimism and positivity is 100% spot on. This might sound odd, but it seriously helped change my positive space of mind. When I saw the opportunity to change brand to Natrol from my other one, I was worried the quality would be different - regardless of price. I thought I would try one. Well, without even thinking about it I noticed a difference. PLUS, I was taking less mg's than I was previously. I'm grabbing this one from now on!
great quality product. it really works as intended. Will definitely get more soon! Thank you so much for this. it was made of high qualiy ingredients. Plus the packaging and sizes were perfect. over all good quality. i love the smell and the looks of it. im looking forward to purchasing another one!
my forever energy booster supplement, I've tried a lot of different brands but this is the only capsule that never fails to amaze me and always gives me extra strength.
these are really helpful for the days I feel a bit sluggish, they help wake me up and give me energy which helps me concentrate at work
It's just unbelievable. The effect from the first acceptance. I didn't think it would help, now I don't think so. Just a great product, I'll order it again.
I'm not a morning bird, so guarana helps me not only to wake up but to get concentrated on my mental work. My mood rises in maximum 30 minutes after taking one capsule. If I need more energy to communicate with clients, I take 2 capsules. Coffee doesn't have such a positive effect on me. Moreover, my blood pressure jumps up after coffee, but is ok after guarana.
It work like coffee for me, but less strong on stomach and can easily take also when travel or when in meeting, Good !
