21st Abilify Update - Insufficient Vitamin D

Today I got my vitamin D test result back. My level is insufficient (23.4 ng/mL), which I think has been amplifying my aripiprazole withdrawal depression. I also learned that low vitamin D levels are linked to lower CYP3A4 enzyme activity, which can increase the concentration of xanax in the body. Because of this, I'm going to start taking 5000 IU of D3 with 100 mcg of K2 and 200 mg of elemental magnesium (glycinate) daily. My current multivitamin only has 1000 IU of vitamin D without K2, and it uses magnesium oxide, which is poorly absorbed. Since my multivitamins has vitamin D 1000iu without any k2, I need to change my supplement
