Micronutrients & recovery
Biathletes should monitor iron and vitamin D levels, as deficiencies are common in endurance sports and can impair performance and health, even if general micronutrient deficiencies are less common in biathletes due to high caloric intake.
Get your iron and vitamin D levels checked regularly. If you are deficient, supplement as directed by your healthcare provider. Focus on iron-rich foods (meat, fish, legumes) and vitamin D sources (sunlight, fortified foods, or supplements if needed).

The primary concerns regarding micronutrient status are generally limited to iron and vitamin D. These findings are typically associated with restrained eating practices and inadequate food variety.
Why this rating
The recommendation is based on general endurance sports data and the specific risks of cold, high-altitude environments.
