Guaranteed Potency. 50% Caffeine. Green Screened. The indigenous people of the Amazon rain forest have used crushed guaraná seed as a beverage and a medicine. Guaraná was used to decrease fatigue and reduce hunger.
"I tolerate this source of caffeine much better than coffee. Coffee makes me mean and intolerant where as Guarana gives me a steady stream of energy without affecting my mood. I am sensitive to caffeine and find 200mg is all I can handle in one day. I take it in the morning."
"This is the second guarana product I've tried. I prefer this one because it is standardized to be 100mg caffeine, so I know how much I'm getting. It definitely provides a nice boost in alertness. I don't feel like I've OD'd. It seems more effective than the same level of caffeine from coffee. Put it this way... a "tall" Starbucks coffee has 260mg of caffeine. A shot of espresso has 75mg. So, a single pill falls somewhere in the middle. However, I prefer guarana hands-down over coffee. This is a very smooth, non-jittery alertness. Great addition on those days you know you just didn't get enough sleep the night before."
"I am a bit sensitive to caffeine. I limit myself to a maximum of 200 mgs per day, so I don't have trouble sleeping at night. I was hoping this product would help me with my focus and concentration. It didn't help very much in that respect, but I do agree with the other users of the product that it's much smoother than caffeine with no crash or shakiness. This dose it very low though. I think I may need a higher dose to help with focus. It also takes a while to kick in, about an hour and a half."
"I like this guarana because it gives me sustainable energy with no jitters or overexcitability, and no crash like coffee does to me. I do have a high tolerance to caffeine, so I find the 200mg (containing 100mg of caffeine) to work well for me. It's not over-the top energy, but it's enough to keep me focused at work and a little extra boost to get through my workout. Energy lasts up to 4 hours."
"I take this every morning that I get up if i'm too lazy to make Yerba Mate. I take it after meals when I have stuff to do, and it's the perfect pick me up. If you take it with a multi-vitamin, it gives you a lot of clean energy. Perfect caffeinated beverage replacement and clean energy. Couldn't live without it to be honest."
