Vitamin B12 supports brain health, red blood cell production, and energy levels. As people age, the body’s ability to absorb B12 from food decreases. This makes older adults more likely to experience low levels, especially those taking certain medications or following restrictive diets.

Low B12 can lead to tiredness, dizziness, mood changes, or memory problems—symptoms often mistaken for normal aging. Over time, a deficiency can also affect balance and nerve function, making daily activities harder.

If you or a loved one notice these signs, talk to your pharmacist or healthcare provider. A simple test can check B12 levels, and treatment is straightforward. In many cases, injections are used to quickly restore levels and maintain them over time.

B12 is found naturally in meat, fish, eggs, and dairy products. For those who follow vegetarian or vegan diets, fortified foods and supplements can help.

Early attention to vitamin B12 levels can prevent long-term complications and improve energy, focus, and well-being. If you’re unsure about your B12 status, visit your local pharmacy team—they’re here to guide you toward better health.
