Which B vitamin is primarily involved in cellular function and growth and often has deficiency risks for vegan athletes?

The B vitamin primarily involved in cellular function and growth, which can also pose deficiency risks for vegan athletes, is riboflavin (B2). Riboflavin plays a crucial role in energy metabolism and the conversion of carbohydrates, fats, and proteins into energy, which is particularly important for athletes to support their increased energy demands.

Vegan diets may lack sufficient sources of riboflavin because dairy products, a primary source of this vitamin, are excluded. This can lead to inadequate intake for individuals following a strictly plant-based diet, potentially impacting their energy levels, growth, and recovery.

Other B vitamins listed also play important roles, but they are not as directly tied to the cellular functions and growth challenges that vegan athletes may face. For instance, while niacin aids in energy production and has cardiovascular benefits, it is generally available in a variety of plant foods. Pantothenic acid is essential for synthesizing coenzyme A, but deficiencies are rare as it is readily available in many foods. Thiamin, while critical for carbohydrate metabolism and nerve function, does not specifically highlight the growth and energy demands that need attention in vegan athletes like riboflavin does.
