Recommended Vitamin B12 Dosage for Seniors
The recommended intake of vitamin B12 can vary, depending on the reasons for taking, age, and gender. In general, the elderly tend to be more prone to a deficiency. Up to 60 percent of adults over 65 years old are reported to have less than optimal B12 levels in their blood. This is because the body produces less intrinsic factor and stomach acid as you age. Both effects would reduce the process of absorbing vitamin B12. Thus, in addition to foods, it is recommended for older people to consume fortified products and B12 supplements. Some studies have shown that a dose of 500 mcg can help normalize levels of vitamin B12. The exact dosage can vary, so make sure to consult your doctor before taking these supplements. [2]
