As women age, it is important to consume adequate amounts of calcium and vitamin D to support bone health. Calcium might be easier to obtain from food than vitamin D as many foods are not vitamin D rich, and for this reason, it might make sense to look for a vitamin D supplement. In addition to these bone-supporting nutrients, omega-3 fatty acids are critical to support nerve cells and are also heart protective. Vitamin B12 deficiency is quite common in individuals over the age of 40, with people over 60 being at the greatest risk. The risk of developing a vitamin B12 deficiency is because there is a decreased stomach acid production as we age. For this reason, supplementing with vitamin B12 or a B complex might be beneficial.
