Triathlon Magazine: Because of vitamin B12’s influence on red blood cells and oxygen transport in the body, it plays a vital role in a triathlete’s energy levels, health, training and performance.

Vitamin B12 is an important nutrient that is involved in many bodily functions, including the production of red blood cells and the metabolism of carbohydrates, fats, and proteins. Some research suggests that vitamin B12 may have specific benefits for endurance athletes, such as:

  • Improved performance: Some studies have found that vitamin B12 supplements can improve exercise performance in athletes, particularly when taken in combination with other B-vitamins.

  • Enhanced recovery: Vitamin B12 may help to reduce muscle fatigue and speed up recovery after exercise.

  • Increased energy production: Vitamin B12 is involved in the production of energy within the body, and may help to increase energy levels in athletes.

  • Improved oxygen delivery: Vitamin B12 is needed for the production of red blood cells, which carry oxygen to the muscles. By helping to increase the production of red blood cells, vitamin B12 may improve oxygen delivery to the muscles during exercise.

Those older than 51 should consume 3.0 micrograms daily. Vitamin B12, or cobalamin, is naturally found in animal foods. It can also be added to foods or supplements. Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells.

A study published in the Journal of Strength and Conditioning Research suggests that vitamin B12 dietary supplements improves athletic performance.

Vitamin B12 Deficiency

National Library of Medicine: Indeed, DNA synthesis is impaired by low vitamin B12, which hampers the activation of folate and, as a result, decreases normal red blood cell production, impairing oxygen delivery []

WebMD indicates, if you have vitamin B12 deficiency, you could become anemic. A mild deficiency may cause no symptoms. Below are possible Vitamin B12 deficiency symptoms:

  1. Weakness, tiredness, or lightheadedness
  2. Heart palpitations and shortness of breath
