Low levels of vitamin B12 may contribute to cognitive problems for older adults in more than one way, according to a cross-sectional study.
Markers of B12 insufficiency all predicted lower global cognitive scores over nearly five years of follow-up, Christine C. Tangney, PhD, of Rush University Medical Center in Chicago, and colleagues found.
But I ask you, aren't there enough natural sources? Yes. It is something found in meats and alternates. Only vegans have to be worried that they do not get enough. Healthy eating is something we can teach those who have not learned these lesson.
The theory is a good one. Ensure you have all the necessary vitamins and minerals. The preference is, always, that you get these form natural sources. Many unnatural sources cannot be readily absorbed and seniors are wasting their money.
