Guarana Extract 2000mg 180 Capsules - Energy Supplement Natural Caffeine Focus and Alertness Vegan

Helpful for fatigue.

These are quite strong so I suggest starting with just one and seeing how you fare. Flavour irrelevant as just swallow! Will buy again when these are running out.

They work but I guess they are for people that are accustomed to industrial quantities of caffeine or people less sensitive to caffeine. Even half gives me palpitations and problems to sleep

I have to be honest: Here and there in the past, I have tried supplements with Guarana. Mostly liquid. This one, is good in the sense that, because of it's considerably high dose, it does give a noticeable boost. Some people may report no effect simply because they are not sensitive to Guarana, or indeed to caffeine. this can happen. Some people shake uncontrollably and can't sleep after taking one coffee, while other people like me, can take 3 coffeees and go to sleep right afterwards.Knowing I am insensitive to caffeine, I usually look for alternatives, preferably high dosage. Ok so, I saw this, bought, and found it effective. However, please be careful!.. Safe recommended dosages of Guarana are 250-300mg per day. Doses greater than that have been linked to side effects. These pills have 2000mg each!!.. To make things worse, the package says in very small letters "take one tablets (plural) daily" so, I mistook this for saying two tablets daily! That's 4000mg per day, for the last 3 months! As a result I have been having extreme irritation in my bladder and urinary urgency (one of the known side-effects). Add that to the fact that I'm already prone to kidney stones and you can imagine how this could have caused serious damage if I hadn't noticed it in time.Again, please understand, this is not exactly the fault of the product but... On the other hand, the recommended dose itself is alread excessive. 2000mg IS excessive for a lot of people. Please be careful, Guarana is not innocuous and dosage does matter, a lot!..

I love this product - this is my second time purchase. It gives you energy, and I prefer to use it only while in office (rather than in the gym). All of a sudden, I can notice my typing ability gets much better, and solving the workload faster. I am using 2 pills for 10 hour shift. The only 'bad' side effect is I am being impatient - as my working speed & performance gets Faster! Will buy more and never be out of stock of this lil gems.

I take guarana quite a lot because I have fibromyalgia full stop they used to be a brand on here that worked really well but they don't sell it anymore. So I've been shopping around for different brands. I tried the 2,000 MG tablet and that wasn't very good so for some reason I thought that the 2000 milligram capsule would be better but it's not! This doesn't work at all, I wouldn't bother buying it.

I tried this product as I had a lack of stamina in the evening and felt asleep even in front of a good movie.It's been 2 weeks I use it and I fell I have got more energy during the day (I take 3 pills a day at breakfast).I can't tell about the fat burner effect.

Does what it says on the tin !
