Didn’t feel any effects.

I didn’t notice any effect from taking alpha brain. I would consider trying the alpha brain black if they did a trial size like the other one.

Disappointing product, didnt help memory or focus

Very disappointed in this product. It did nothing for my memory or focus. And it gave me a big headache, making me feel like im hungover.

game changer

Clears my mental fog. I tend to lose words the harder I think or the more nervous I am. It's helped me regain confidence in social matters. Thank you

Memories

I don’t think it did much other than give me stomach issues. After taking this product, my memory to never buy it again is ever sharp in my memory.

Too expensive

The product itself feels effective however the price is too high for the number of capsules dispensed.
