Dr Best D 5000is what we always get. Older people have trouble absorbing enough vitamin D, so we need more to benefit from the immunity power of Vit D. It also prevents cancer. Take with at least 120mcg of vitamin K2 in its MK-7 form. The cheaper vitamin K2 in the MK-4 form is synthetic and does not work as well.
