Vitamin A
Supports immune function, vision and cell growth. Important for maintaining training consistency.
Why it matters
Vitamin A encompasses a group of fat-soluble compounds including retinol, retinal, and retinoic acid. It is essential for immune function, vision (particularly in low light), skin integrity, and cell differentiation. It plays a role in gene expression and supports the development and maintenance of epithelial tissues the first line of defence against infection.
For endurance athletes
Adequate vitamin A helps maintain the immune resilience needed to sustain consistent training. Heavy training loads suppress immune function athletes who are consistently low in vitamin A may find they get ill more frequently, breaking training blocks at critical times. It is also important for respiratory tract integrity relevant for athletes training in cold or polluted environments.
