Very Good Balance of B Vitamins
I was looking for a B complex that had a higher B1 but not too high as too low relative to the other B vitamins caused problems with heart palpitations, at least with me. Also higher B1 enables better sleep in my case, but too high it does the opposite. So this has 75mg of B1 which is about right. It also has vitamin B6 which I need for better zinc absorption which I also take. In the past not taking anything that has B6 was causing very low concentration and clarity of thought. So this is what I need.
