Hello, I did my blood test last week and my 25-OH (D2+d3) is at 26.4ng Before test i took from 500iu to 1000iu of d3 daily for few months. I will be doing another blood test in 3 months. What dose do you recommend I should take so that in 3 months my levels will be between 55ng and 60ng. I'm 30 years old and I live in Canada. Because of my work schedule I dont get lot of sun in summer or winter. Thanks
