Wow! I was honestly surprised at how much clearer my mind felt after taking this. I started with two a day like other reviewers suggested, and it really helped me with mental clarity. I noticed way less brain fog and better focus after taking this. So happy I added this to my routine!

Working in a fast-paced environment, I’m always looking for an edge to keep me awake and my mind sharp... I tried GeneIII on a friend’s recommendation. After a few weeks, I definitely felt the difference. Mentally, I feel quicker and sharper. Physically, my gut felt “cleaner”.

I’ve been taking this supplement for two months now and I feel more energized! I am naturally a sleepy person but ergothionine has helped me stay awake during the day and I feel more focused too. I highly recommend.
