  1. Hana from Amsterdam, Nederland

    Werkt goed om mijn concentratie te verbeteren. Merkte snel verschil bij studeren. Prijs is redelijk voor de kwaliteit.

  2. Thiago from Berlin, Germany

    Schnelle Lieferung. Wirkung ist ok, kann manchmal helfen sich zu konzentrieren. Nicht sicher ob es täglich notwendig ist.

  3. Alejandro from Los Angeles, USA

    I’ve tried a few brain supplements before. This one feels different. Helps me focus more at work, which is nice. Not sure if I noticed anything huge yet but I’m sticking with it for now.

  4. Bjorn from Stockholm, Sweden

    I feel sharper since using this. Easy to mix and drink daily. Noticed improvement in memory after two weeks.

  5. مايا from القاهرة، مصر

    مستحضر ممتاز لتحسين التركيز. أحسنت أنه ساعدني على زيادة الانتباه أثناء الدراسة. يمكن أن يكون مذاقها أفضل.

  6. Koa from Los Angeles, USA

    Took these for a month. Notice some improvement in focus. Taste isn’t great, but bearable.

  7. Linh from Ho Chi Minh City, Vietnam

    Helped with my focus and memory during study sessions. Easy to mix in drinks too. Definitely feels sharper overall.

  8. Moon

    I’ve been experiencing difficulty concentrating and my memory isn’t as sharp as it used to be, so I was looking for a brain health supplement when I came across Nutrikay Brain Focus PS80.

    I usually think of pills when it comes to supplements, but this product comes in powder stick form, which is really convenient to take. That caught my attention right away.

    Taking It & Taste:
    Each box contains 15 individual sticks, easy to carry in your bag and take whenever needed. The taste is almost neutral with a slight nuttiness – goes down smoothly with just a sip of water.

    My Experience:
    I didn’t expect dramatic changes overnight, but after taking it consistently every morning, I noticed my concentration lasting longer during work. The afternoon brain fog that used to hit me has reduced noticeably.

    The key ingredient is Phosphatidylserine at Korea’s highest 80% purity. Since it’s a major component of brain cell membranes that decreases with age, supplementation makes sense. Also contains Banaba leaf extract for blood sugar management.

    Overall:
    Great for taste and convenience. If you take it consistently, it helps with brain health and maintaining focus/memory. Especially recommend for those who struggle with swallowing pills!

  9. Kitty

    My mom is almost 70 and has been telling me how scared she is of getting older because she’s been forgetting things more and more lately. She’s really worried about possibly getting dementia.

    Seeing her like that broke my heart, so I started researching and found out about brain supplements. They’re even featured on TV shopping channels these days.

    I first ordered this about 3 years ago. At first, phosphatidylserine was such an unfamiliar supplement to me that I looked into different brands before settling on Nutrikay.

    The powder stick format is so convenient – easy to take and carry around. My mom loves it!

    Sure, the powder type is a bit more expensive than pills, but it’s worth it for the convenience. She’s been taking it consistently, trying different brands over the years, and now she’s back to Nutrikay with the new PS80 version.

    She says it tastes a bit nuttier than before. I can’t say for certain if it’s working, but mom seems less anxious about her memory now. That peace of mind alone makes it worth it!

    If your parents are worried about forgetfulness, consider getting this for them. The psychological comfort is real!

    Nutrikay Brain Focus PS 80 – Phosphatidylserine KFDA Certified 80% Purity

    I’ve been forgetting things more often lately. While watching a TV health program about brain health, I learned about the importance of Phosphatidylserine (PS) for the first time.

    Our brain’s hippocampus, which handles memory, is like a dense forest of trees. As we age, these brain cells and dendrites decrease. Beta-amyloid, a major cause of dementia, builds up over time. To prevent this, we need to keep our brain cell membranes healthy – that’s where PS supplementation becomes essential.

    Why I Chose Brain Focus PS 80:
    Among all the products available, I chose this one for its purity and safety. With 80% or higher purity (Korea’s highest level), plus the 2025 Triple Brand Award and KFDA certification for cognitive improvement, I felt I could trust it.

    Made with US FDA GRAS-listed safe ingredients and Non-GMO soybean extract. Also includes 4 functional benefits: cognitive improvement, blood sugar management, immunity, and skin health.

    Perfect for anyone worried about dementia or wanting to maintain cognitive function!

    Nutrikay PS80 Review from a 50s Office Worker

    Why I Started:
    After turning 50, I noticed I was having trouble focusing during work and struggling to recall words. Wondering if it was just age, I felt increasingly anxious about it and started looking for brain health supplements. That’s when I discovered Nutrikay PS80.

    Phosphatidylserine is a KFDA-certified ingredient that helps improve memory. The 80% purity gave me confidence in its quality.

    What I Noticed:
    Honestly, I didn’t feel much difference in the first week. But after about 2 weeks, my head felt clearer and I was able to focus on work longer. The pattern of losing concentration in the afternoon definitely improved.

    Great for those concerned about forgetfulness or declining focus. Highly recommended!

  13. Marley Evans Seattle, USA

    I’ve been using Nutrikay for a few weeks now. Noticeable focus boost during work hours, helps me stay sharp.

  14. Aiden Los Angeles, USA

    I’ve noticed better focus and memory since starting these. Easy to use daily sticks in the pack. The quality is solid for a reasonable price.
