The human body depends on Vitamin B12 to generate red blood cells, while maintaining a healthy nervous system. After age 40, people experience reduced B12 absorption, which results in tiredness, muscle weakness and memory problems. Most women cannot get sufficient B12 from their food sources particularly when they eat only plant-based diets. Supplements containing B12 help increase energy levels, while they protect cognitive function and preserve nerve health. B12 functions optimally as part of B vitamins, when included in multivitamin supplements which are designed for women beyond 40 years old.
