Since many months, I have been having a lot of brain fog, easily getting distracted, impulsivity and anxiety. I heard that vitamin D and B related deficiencies could be one of the reasons for this. So I got a complete vitamin profile tested. Acc. to report, I fall in insufficiency range for vitamin D (23.26 ng/mL) And for B vitamins, for most of them, I'm on the lower end of the normal levels. B12 - 386 pg/ml B1 - 0.78 ng/ml B2 - 8.63 ng/ml B3 - 0.38 ng/ml B5 - 84.26 ng/ml B6 - 14.84 ng/ml B7 - 0.25 ng/ml B9 - 0.21 ng/ml Please suggest me what should be the vitamin supplementation that I should take so that the these vitamin levels stay high. This will help me. Thanks a lot
