    I brought x2 and the first tub I opened had big clusters which is hard to break up. My brain loves this stuff but not sure if it has helped gut wise, made me very gasy

    I am a definite convert to the brain x gut powder. It tastes amazing - both added to my morning breakfast or as a drink on its own. My brain fog is definitely less and feeling a little less bloating.

    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.

    Breakfast - yum - favourite meal of the day. The Brain Gut Powder with muesli/ fruit/ yoghurt sets me up for robust thinking and a settled gut. It is seriously the best addition I have made to my life schedule. I couple up with a calm & clarity drink mid afternoon and having the best productivity that I recall for a long time. Give yourself this to be your best - if you are like me it’s so worth it!! ❤️

    Yoghurt, chia seeds, sunflower seeds and walnuts, to be topped with my favourite fruit. Mixed with my brain x gut powder for a great taste and vibrant colour! Got to be the best breakfast. A ‘feel good’ of all kinds.

    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 👌

    Customer photo review of The Brain x Gut Powder⁺

    Into my second week of this and about to order more. Tastes delicious and has had a favourable effect on my gut health already🤗

    The Brain x Gut Powder⁺

    What I have noticed is that my finger nails have never been stronger! I am an avid gardener, so fingers in soil a lot! I have never really painted/put polish on my nails because they haven’t been long but now, they are growing gang busters and are strong!! Coats of polish happening! Thats a first because my nails were softer and haven’t sustained much length. I am 70 years old and have just started wearing nail polish regularly as a result I did not expect that ?? But I can only put it down to your product because nothing else is different for me diet wise. How about that? Have others noticed that improvement that you are aware of?

    The Brain x Gut Powder⁺

    Definitely feeling more stability in my gut. Will continue to ise

    The Brain x Gut Powder⁺

    For fifteen years, I've battled herpes, relying on antivirals for temporary relief. Discovering Dr. Enosetale herbal cure through a blog changed my life. Inspired by another's recovery story, I contacted Dr. Enosetale and He guided me through his natural treatment, and to my amazement, his herb erased every trace of HSV from my system. It's been over six years, and I'm still herpes-free till date after using Dr Enosetale herbs. His remedies truly transformed my health. If you're seeking more than just symptom relief, reach out to Dr. Enosetale. His approach has given me my life back. Forever grateful email: dr.enosetale667 @gmail.com WhatsApp : +2347031966178doc
