Life changing for me

Posted by Reviewer2229628 on Jun 10, 2017 | Verified Purchase

I have an auto immune disorder that causes cognitive issues, and word finding issues. I was having trouble adjusting to change at work. I would make several mistakes more times than is normal when processes change. In addition, I had trouble writing emails and remembering words. I lived in daily fear of getting fired. It caused depression and anxiety. I decided to try this medicine after exhaustive research. I've taken it for three weeks now, and I feel sharper every day. I can do mental math again, something I've not been able to do for about a year. I can write and spell correctly-- no writing around the word--- I know it. In addition my pain due to my disease, while not gone entirely seems to be diminished, and my mood is far better as a result. I am anxious to see if it will continue to improve in the coming weeks. Most studies done show the most improvement by week 8. I recommend this highly if you have MS or fibromyalgia, or Alzheimers or cognitive issues. It has been a life saver, and may potentially allow me to work for a few more years. That's incredible- I was actually considering disability.

Thanks for your feedback!

So far, so good.

I've only been taking this for a couple weeks, but it seems to be making a positive difference in my overall energy levels. I take so many supplements, it's sometimes difficult to gauge effectiveness over such a short time.

Thanks for your feedback!

No mushroom fruiting body extract, only mycelium

Posted by 4727183900159137734 on Nov 10, 2016 | Verified Purchase

I don't believe that the mycelium alone is as powerful as the fruiting bodies and the mycelium combined. Overpriced.

Thanks for your feedback!
