Vitamin B12 is essential for the production of red blood cells, nerve function, and DNA synthesis.
Symptoms of B12 deficiency may include fatigue, weakness, anemia, difficulty concentrating, memory problems, and numbness or tingling in the hands and feet.
Vitamin B12 is primarily found in animal products. Therefore, individuals following a vegan or vegetarian diet may be at a higher risk of B12 deficiency.
Runners with certain gastrointestinal conditions, such as celiac disease, Crohn's disease, or atrophic gastritis.
Some medications, such as proton pump inhibitors (PPIs) and certain types of antacids, can interfere with the absorption of vitamin B12.
Vitamin B12 absorption tends to decrease with age. Older runners may be at a higher risk of deficiency and should pay attention to their B12 intake through diet or supplements.
Regular blood tests can help assess vitamin B12 levels. Runners, especially those in high-impact training, should consider including B12.
In cases where dietary intake is insufficient or absorption is compromised, supplementation may be recommended.
Animal products such as meat, fish, dairy, and eggs are rich sources of vitamin B12. Runners should include these foods in their diet to ensure an adequate intake.
If runners experience symptoms of B12 deficiency or have concerns about their B12 levels, it's important to consult with a healthcare professional.
