Moderately effective. I started out taking 3 capsules at a time and have taken up to 5. It seems to work “some” but reminds me a lot of when I take high potency b12.

Great for clarity

I took the product first thing in the morning before breakfast, as suggested, and had zero issues with nausea or other issues. I noticed a better ability to focus and stay focused whatever task or project was at hand.

Honestly I love it, I feel SO focused and productive. I know what I want to get done, within the time frame I want to do it in, and I've been able to stay focused and execute. I also am very focused socially and conversationally. I also have more motivation and energy to do all these things.
