Actually works!
I wanted to wait a few weeks before writing a review to properly gauge any effects or lack thereof, as I didn't want to jump into it without knowing the product. I'm almost surprised to find that I'm delighted with this product. I was diagnosed as 'hyperactive' in the days before it was renamed ADHD/S, and with elements of dyspraxia, I was never 'treated' for this issue, nor did I have any help from health professionals, and it has been a problem most of my life. Recently my daughter encouraged me to find out if there were non 'medical' options available. this is why I purchased your product. It has made an enormous difference to my life. I feel more alert and focussed, I'm able to concentrate for longer on daily tasks where I would normally have butterfly mind hopping from one task to another and not always finishing them all. I also have the tendency to hyper-focus on things I'm very interested in, which can be linked to ADHD, while useful at times it can also suck up too much of my time when I should be doing other things. Now I find I'm able to tear myself away from things I'm fascinated with to do essential things outside of that focus, and not neglect those other more 'mundane' but important tasks. The first week of taking it I felt fizzing with energy and life and tackled everything I'd been putting off or just tinkering with. After taking Nootrostim for coming up to 4 weeks I notice that I sometimes need two capsules to feel the full benefit, but usually one a day is enough. If I don't take it for a day or two, I notice the old fogginess, and jitter brain starting to resurface. Unexpectedly it also seems to have helped a little with weight loss. I've been intermittent fasting (16:8) for health reasons for a few months, and had lost 8Lb, but was not continuing to lose weight. While weight loss would be great, it was not the main reason I've been doing this, however since taking Nootrostim I've lost a further 4Lb without altering anything else that I'm doing, except maybe I'm a little bit more active - I can't alter my activity levels by much at all eg by exercising, as I have a mobility problem which makes me very sedentary. All in all I'm very impressed with this product and will definitely continue to purchase. I have also contacted the email address included in a small stick on 'leaflet' on the lid of my purchase, offering a free bottle if you contact them and let them know what you think of the product, negative or positive. - The customer service is great. I initially missed the code they emailed me to use for a free 'bottle', when I did noticed it the expiry date had already passed. I was cheeky and contacted them to ask if it would be possible to send another or reactivate the code, and they did very quickly, I now have my free product. A little update, I've been using this product for a few months now and during this time I missed a couple of weeks, because I got complacent, I wondered why I was feeling lethargic, wooly headed and generally 'scattered' and realised I hadn't been taking my tablet, I noticed an improvement pretty much immediately I resumed taking them and now wouldn't be without them.

A truly game-changer to my daily routine!!!
I write this review regarding the use of this product, "NOOTROSTIM" which I purchased from Amazon. After two weeks of using these capsules since March 29th, I can confidently say the results have been outstanding!!! From day one, I felt vibrant and alive, but I wanted to give it time before sharing my experience. Now, I’m sure - the benefits are real!!! My mind feels clearer, free from the usual fogginess, and I no longer experience lethargy. Unlike caffeine, this product gives me the boost I need without any jitters. I started with one capsule a day as directed, but I now take two sometimes, and the effects remain consistently amazing. A truly game-changing addition to my routine!!!

Increased brain power and energy
Nootrostim is a good product, perimenopaise brain fog is my main complaint, this medicine working to a certain extent. noticeably sharper and more energetic. Helps with recalling words during presentations, making less stressful. It does seem to cause further sleep disturbances, I already had this issue.

A colleague reccomended this! Wow!
I had been really struggling to focus. I was tried and burnt-out and could not motivate myself to do much. Everthing felt like a struggle. I colleague had recommended this to me. I was dubious at first on the first day I took one tablet and noticed a slight improvement, day 2 I took the full suggested dosage and all I can say is i noticed a significant improvement, in concerntration, motivation and focus I felt it was it really helping me. Unfortunately, when it came time to get a replacement bottle I was unable to do so on Amazon or Ebay. When my bottle finally ran out, I emaild Addrena, who got back to me within about 24 hours explaining the issue was with stock and amazon. The team appologied and promised to get in touch when the issue was resolved. Since then, I have been diagnosed with ADHD. A couple of months have passed since I emailed Addrena and I had completly forgotten the email conversation I had had with Melody at Addrena. However, today almost 2 months on and out of the blue Melody reached out, telling me the issue had been resolved and even offered me a free bottle. It really helped me pre my ADHD diagnosis. So if you are waiting for a diagnosis (the waiting list is long), or if you are diagnosed but decided not to be "medicated" I highly recommend this! Thank you Melody and Addrena, keep up with producing good quality producys that work and the absolutely fantastic customer service. D😇

Bitter orange and sub optimal ratio
Interesting to see no review in 2026 with most being quite dated. Interesting because the introduction of bitter orange is a big downside with science clearly showing regular ingestion associated with increased blood pressure and raised heart rates / palpitations. The ingredients listed by most here predate this change. 3 stars because the combination of Lithium and Caffeine will inevitably be effective, however important to note ratio for most top products is 2:1 and not 1:2. This is caffeine heavy and to consume adequate Lithium you need to have much more caffeine that optimally recommended. This is why many need to take 2 or more. Plenty of more affordable options for Lithium Caffeine at 2:1 which do not contain bitter orange. Although this works I'd recommend looking around for a better option. Powder Lithium with water and a strategic espresso shot far more effective, healthier and affordable.

High energy, low focus, anxiety up
I'm a futures trader focus is absolutely necessary in my work because I stare at charts 8-12 hours a day. I'm also an ex GAD (general anxiety disorder) which means my amygdala is still slightly overactive. Going back to above mentioned that Ive tried over the two months the only thing this thing does is increase your energy. Most likely this does lower your gaba neurotransmitters because it was making me a bit uneasy, nervous. full of energy at the same time this was not the type of energy anybody would enjoyed.. More less mild amphetamine without euphoria. It did make me more anxious but anxiety is something I managed to slay over the last few years.. thought that's interesting because for no particular reason i was getting this anxious feeling. And realised quickly this was causing the problem after 20-30 min of taking it. Sure you notice the difference in energy levles but this ain't worth it. Better get yourself an extra cup of coffee rather then taking this crap. It gives you heart palpitations too... sooo yeaaah imho it's a no no suma summarum energy up, focus down. anxiety up but it might be only me. this stuff goes to the bin now

Surprisingly effective!
I’ve been using your supplement on and off for the past 3 months and I have to say, after initially being pretty sceptical I am very impressed. Not only does it wake me up (which I usually can kind of do with a cup or coffee), but it gives me this clear mind with which I can sit down to studying and actually absorb what’s in front of me. What I am also very impressed with is the motivation that I feel after taking these pills. I’m not sure whether it’s the placebo effect or there’s actually something in these that helps with it (or it might be just me deciding that since I’ve taken one of your pills, I am actually going to sit down and focus), but it is amazing. On days when I would wake up, the weather would be crap and I already feared that I wouldn’t get anything done because it’s depressing, I would just pop one and boom- suddenly I’m inspired and happy to sit down and get some work done! Overall, I obviously try to keep consumption to minimum as everything is good for us, as long as it’s in moderation- but whenever I do decide to take it, I am always very pleased!

Wow
Seriously wow. I've been taking these pretty consistently for about 3 weeks now and while it took a while to find my best dose and things are still evolving, this is the best nootropic that I have tried over the last two years. I got really sick 3 years ago and this affected my mental capabilities pretty severely, which was terrifying given I was starting Vet school at that time. Focus, concentration and memory retention were all compromised. This product has helped with the first two and I have noticed a gradual increase in memory building which is the most I can say for anything over the past few years. Dosing is very important to stave off the jittery or over-energised feeling that caffeine or other stimulants have produced for me, but having increased my water intake to 2-3 liters a day and timing what I eat around when I take the very easy to swallow capsules has been unbelievably effective in getting me to focus on my very heavy workload. I was always weary of adderall like stimulants that either cause dependence or can cause focus on the wrong things, but I do not feel this way about Nootrostim. But possibly the best thing about this product is the amazing customer support that I received from multiple Nootrostim representatives, who not only checked in to ask about efficacy, but offered advice and forums to customise my experience. Melody in particular has been an absolute God-send and I cant express how happy I am with her help. The company and it's workers seem to genuinely care, and that is worth its weight in gold. Side note, I have been on a diet due to the extreme weight gain from my illness and for the first time in two years I am noticing a huge change. I have been losing weight more consistently since starting Nootrostim, which is an added bonus!
