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

“Working in a fast-paced environment, I'm always looking for an edge to keep me awake and my mind sharp. Coffee and Red Bull don't cut it for me anymore, so I tried Gene III 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." Highly recommended!"

I have been taken this L-Ergothioneine Supplement for about a year now, and very happy about it. I used to have difficulty in sleep, due to age, but now the problem has gone away since I start on this supplement. I take one at bedtime and usually get a sound sleep through the night. A good supplement to have, especially for someone having sleep problem. Highly recommended.

I bought this product because I was curious about all the benefits I heard on Ergothioneine and decide to test it out myself. I was skeptical at first but after taking 2 capsules a day, I started waking up feeling more refreshed when I hit the 3 weeks mark. I did not change anything on my exercise or eating habit, so I know it must be this supplement.Would definitely recommend to try it out for increasing energy level and better sleep quality!
