Vitamin deficiency in later life

(Helmholtz Zentrum München - German Research Center for Environmental Health) One in two persons aged 65 and above has suboptimal levels of vitamin D in the blood. This is the conclusion of an investigation conducted by researchers at the Helmholtz Zentrum München, as part of the population-based KORA-Age study in the region of Augsburg. Moreover, as the authors of the study report in the peer-reviewed journal Nutrients, one in four older adults has suboptimal vitamin B12 levels.
