    Helps With Mental Fatigue & Depression

    Posted by iHerb Customer on Jan 05, 2018 | Verified Purchase

    For years I worked in a high pressure job. As the day wore on, the constant mental activity would leave me feeling burned out and, I won't say "depressed" in the clinical sense, but nonetheless less able and not as able to concentrate or be cheerful. Then I someone put me onto B vitamins and B1 in particular. Now, I can feel my body running out of B vitamins as the day progresses because I can feel that it is not running with the level or ease that it was before. And so I take a B vitamin complex and 100mg of 21st Century B1 in the morning with breakfast and also with lunch and I can truly say that the result has been huge. So great in fact that I now firmly believe that B vitamins, and again B1 in particular, are greatly overlooked in the treatment of what are generally considered to be mental health problems. Not because it is a miracle cure but because it allows our bodies to access the energy necessary to operate at a high level, both mentally and physically. You know, like when we were kids and never ran out of steam. But they are burned up and so our stores of them need to be regularly replenished and 21st Century 100mg B1 is perfect for this and at a great price.
