    I have felt immediate benefits from taking this consistently for 2 weeks. I am 3 months postpartum and this has significantly helped with brain fog ‘baby brain’ and also helped with muscle energy for my return to running.

    I've only been using The Brain X Energy Powder for a short time as part of a new morning routine - I have noticed my energy levels both physically and mentally at the end of the day have improved. I enjoy the slightly sour taste.

    I love this drink. As a shift worker I often find I am sluggish and need a pick me up that won’t affect my sleep. This is my second order of Arepa and I find it works wonders. It helps me think clearly and be more focused without the slump you get from having coffee etc.

    I have been using the original Arepa on and off for a few years now after a delayed concussion and loving it. Definitely notice the difference when i haven't used it. Now trying the new gut and energy but too soon yet to notice a difference. Thank you Arepa!

    Big Fan, have noticed the difference significantly especially in afternoon energy levels

    Customer photo review of The Brain Capsules for Cognitive Function

    At first when I started taking them. I felt a little Buzz of clarity and focus but now a few months in I’m not sure if I’m still feeling the same effect as I did originally I generally take two a day one in the morning one in the evening. What I did notice in the first two months was that during a game of sport of any kind? I felt I was concentrating and more sharp in my thinking and delivery, so I’d recommend them for anyone to try and see if it makes a difference in their life.

    After a busy day I took my Arepa capsules in the afternoon which helps to give me a burst of energy before when I go out in the evening.

    Customer photo review of The Brain x Gut Powder⁺

    Works well, increased energy and keeps me awake when my body wants to sleep. Great for night shift hours, also has lead me to ordering creatine powder to try as well. I add the powder to water that is filtered and magnetized, and it increases the vitality of my drinking water. Has helped me to reduce my intake of energy drinks, 2 small bottles with Arepa powder and water a day has replaced 2-4 energy drinks and/or soft drinks I used to drink daily. Cutting costs at the supermarket at the same time switching to a much healthier diet instead of biscuits, snack foods and sugary drinks. A step forward to better health, highly recommend Arepa.

    This must be my third order by now and I always go for the two servings because the price works out better! While on the waitlisted for my sleep apnea machine, these little gems had been a life saver, helping me get through the mornings when I would usually nod off at work! I stopped using them for a while once I got my machine but I’ve gone back to using them to help get me through my full busy days. I do a lot of mental processing and engagement at work, and without feeling like I’ve taken anything to give me a buzz like an energy drink would, I just have the energy I need to keep going. Consider me a long time customer!

    Arepa has been a real game changer for my focus and energy levels in a busy and challenging industry where being on your game really matters. It's become a daily part of my diet and I can notice the difference it makes.

    Customer photo review of The Brain x Energy Powder⁺

    This drink has changed my morning routine from ‘groggy wanderer’ to ‘vibrant warrior’. I feel the energy in my brain, supports my ability to think and process, make sounder decisions and get things done! I also have it as an afternoon pick me up which lasts all evening. Perfect for times when my day doesn’t seem to end having errand after errand, tasks and commitments. I will always get a prescription of this drink

    After doing extensive research & trialling others, these are now my go-to nootropics on auto refill with subscription. It gives me comfort to keep a couple of months extra supply in stock, just in case there is ever a shortage while the world is still unpredictable. I take two capsules every morning. I felt the difference within the first week or so & haven’t looked back since.

    Customer photo review of SALE - The Brain Drink for Calm & Clarity - Sparkling Blackcurrant

    CALM AND CLARITY Brief Summary of last 23 years August 2002, 6:30am Traumatic brain injury, air ambulance to RPA Sydney. Results from injury, extreme light sensitivity, complete muscular failure, epilepsy, narcolepsy, cataplexy, unable to walk, write, read, barely able to talk, uncontrolled vomiting due to extreme vertigo, loud tinnitus. Bedridden for many years, living in total darkness with all windows an doors sealed to stop any sneaky light which caused extreme vomiting and nausea for 15 years. Could not stand anyone touching me my body was highly sensitive. Fractured pelvis from twice epileptic seizures, chronic pain Tried health specialist everywhere to get help but everyone said they couldn’t help me. Family gone like jumping in a panic off a sinking ship, they don’t even know that I have healed myself. Extreme Vertigo finally gone mid 2023 through using frequency therapy. I have always had full cognitive function, have the best memory of past and present, occasionally I have brain fog but that is because of what the towers, wifi and phones are sending out. I have purchased a special cap that blocks all this and tried it out for first time on this Thursday when shopping and no brain fog. When you know your body it’s easy to find what is causing problems. I have rehabilitated myself through sheer determination with the assistance of my beautiful Holi helping me to walk again by pushing her up and down the hallway even though I banged into the walls, tipped her off the stroller quite a few times she kept insisting on more rides. I am having the best life, living it to the fullest. Thursday 35 minute drive to the beach where I spent 40 minutes in the water, then home and to Petbarn and Bunnings, home so my support person could vacuum etc, then to the Organic shop for fresh veg etc and then to another shop for a few items and wearing the cap no no brain fog still as sharp as a tack after 4 hours shopping 🤣 I have always been a active high vibe being before the injury and now I am back and I find the Calm and Clarity helps me stop, take a break, just chill and watch the birds and world go by. 2018 I was accepted into a brain injury scientific study at one of the university’s, so sent them DNA sample as requested. 11 months later the results were in, No mental illnesses, No family carry over illnesses, nothing wrong at all, in fact the study said I have perfect DNA. Thank You for thinking outside of the normal narrative and producing a great outstanding product ❤️🙏🏼 Meredith

    Customer photo review of The Brain x Gut Powder⁺

    Absolutely delicious, I love the Arepa brain & gut powder mixed in Kalo vanilla bean yogurt, Devine flavor experience, added to my chia, oat, coconut/almond milk breakfast with fruit & nuts, or as a desert anytime with just the powder mixed into the yogurt, best of all my chronic brain fatigue has improved immensely, my mental energy is so much better & no more "sore brain" feeling, fatigue still builds up but without me actually noticing it now, so still hit the wall a bit, but nothing like it was. Remembering to pace myself but not as much as before. Soothing on the digestion which is another huge plus.

    Absolutely love this. I'm 36 have been struggling with severe bloating for over a year and nothing seemed to help until I started taking this. Before I've even finished the glass the bloating is already going down and the discomfort is nearly non existent. I can't believe how quickly it works, absolute game changer. Also it has noticeably improved my mood and energy levels. Highly recommend 👌

    My husband and I have been adding it to my breakfast to give us the mental clarity throughout our workday. My two sons enjoy the drink and use it to increase their alertness while studying for exams. Lastly, my daughter also drinks it to help with brain fog, she has Graves' disease. Our family loves it! It is great to have a product that is caffeine free! Ngā mihi The Hirschfeld's!

    Tennis is my favorite sport! I love hitting the court for both social games and interclub tournaments. And honestly, Arepa is my secret weapon — it keeps me fueled, focused, and calm so I can outsmart my opponents. At this point, Arepa’s basically my tennis buddy — I never show up to a match without it!

    Heading into week 4 and still finding I'm taking up to an hour+ to get to sleep. I can also sometimes find myself awake up to 2 hours if I wake in the night. Interestingly however I'm not always waking exhausted in the morning despite the not so restful night.

    Customer photo review of The Brain Capsules for Sleep Support

    I am so, so happy with these! I started taking them when I was busy and stressed due to work pressures - keeping me up at night... At first I wasn't sure if they were working, but over a few nights I definitely started to notice a difference - easier to get to sleep and stay asleep being the most notable difference for me. I would highly recommend these to anyone who is struggling with sleep consistency, they have really done the trick.
