Micronutrients & recovery
Adequate intake of essential micronutrients (Vitamins A, B6, B12, C, D, E, folate, zinc, selenium, copper, iron) is required to support optimal immune function and reduce susceptibility to infections.
Ensure your diet includes a wide variety of fruits, vegetables, lean proteins, and whole grains to get essential vitamins and minerals. This supports your immune system's ability to fight off infections. If you have known deficiencies, consult a healthcare provider for testing and targeted supplementation.
GoodSupportsHIGH confidence
A number of vitamins (A, B6, B12, folate, C, D and E) and trace elements (zinc, copper, selenium, iron) have been demonstrated to have key roles in supporting the human immune system and reducing risk of infections.
Why this rating
Supported by multiple meta-analyses and systematic reviews cited in the text (e.g., Vitamin A, D, Zinc).
