Aging bodies can have difficulty absorbing key vitamins and minerals, leading to deficiencies with easy-to-miss warning signs. The Aging Untold hosts discuss common deficiencies in older adults, including what to watch for and questions to ask a doctor. A vague, unidentifiable feeling of not being oneself can be caused by nutrient deficiencies, according to Dr. Rhea Rogers, a board-certified physician.

Vitamins and trace minerals are crucial for the body's cells to function. Dr. Rogers highlights vitamin B12 and vitamin D deficiencies as particularly significant.

Further information on these deficiencies and their effects is available from the Aging Untold hosts and Dr. Rogers.
