Vitamin C: The Frontline Defender for Athletes on the Move

Build a colorful plate with oranges, kiwi, strawberries, bell peppers, and broccoli. These foods help support immune resilience during heavy training cycles and reduce gaps that can appear when appetite dips after intense workouts.

Vitamin D: Sunshine Support for Respiratory Defenses and Recovery

If sunlight is limited, discuss a vitamin D blood test with your clinician. Adequate levels are linked with better respiratory resilience, which matters when training volume rises and colds circulate in team settings.

Use fortified dairy or plant milks, eggs, and fatty fish like salmon. Short, safe sun exposure when possible can complement food sources. Keep habits consistent through winter so your immunity does not dip with the temperature.

B-Complex Vitamins: Metabolic Engines That Prime Immune Readiness

Endurance demands and the micronutrient margin

Higher training volume can increase nutrient turnover. Ensure a steady intake of whole grains, legumes, leafy greens, eggs, and lean proteins to keep B vitamins sufficient when mileage climbs and recovery windows narrow.

Vegetarian and vegan athletes: be deliberate with B12

Plant-forward athletes should prioritize B12 from fortified foods or supplements after consulting a professional. Balanced folate and B6 from legumes, greens, and seeds keep energy reliable and help immune systems stay responsive.

Quick plate ideas for busy training weeks

Vitamins A and E: Antioxidant Allies for Mucosal Defense and Recovery

Choose orange and dark green vegetables—carrots, sweet potatoes, kale, and spinach—for vitamin A. Add nuts, seeds, and olive oil for vitamin E. Food-first variety helps avoid excessive doses while supporting daily training demands.
