Why the Choline bitartrate? I would replace it with Cordyceps, at least 500 mg per serving. Did you make sure to check whether you are getting genuine Panax Ginseng or not? Many suppliers, either knowingly or inadvertently, will sell American Ginseng and claim it is Panax. Article on it: http://nootropicsdepot.com/articles/what-you-might-not-know-about-panax-ginseng/
Thank you for your reply. I did a little experiment with 40 people - 6 of them did not experience any noticeable change after trying M-Drink without choline bitartrate. Few days after that experiment they tried M-Drink with choline bitartrate- One of them noticed significant effect and two of them noticeable change. I understand this is too small group to make conclusions based on that, but it is not particularly expensive. To conclude I included choline bitartrate because it might have an effect on those who otherwise would not experience it and it is not expensive. I will take your advice and do some in-depth research in Cordyceps.
Thank you for information about Ginseng, I did not know that and it is very helpful. I will order few samples from different suppliers and run a test.
I will keep you notified! 🙂
