Immune health: everyday habits and supplements
No single food boosts the immune system. Balanced food, sleep and appropriate vaccines form a foundation; supplements are not necessary for everyone.

Stronger does not always mean healthier
Immunity involves cells and organs working together against infection. The aim is normal function, not constant stimulation. Frequent illness alone does not diagnose immune deficiency; recurrent, severe or prolonged infections need assessment.
Practical everyday habits
- Vary vegetables, fruit, whole grains and suitable protein sources rather than relying on a superfood.
- Plan regular sleep and activity appropriate to your condition; avoid smoking.
- Check age- and condition-appropriate vaccines with your team. Vaccines protect against specific infections.
Vitamins and herbal products
Without a deficiency, vitamin supplements generally do not prevent infections or speed recovery. High doses can be harmful, and herbs can interact with medicines. Garlic, tea or supplements do not replace vaccination or treatment. Tell your clinician about every product you use.
Children and situations needing extra care
Children should not receive supplements adapted from adult advice. Probiotic effects differ by product and purpose; they can pose risks in immunocompromised or seriously ill people and premature babies. A child’s growth, diet and infection history need assessment together.
When to seek help
Arrange assessment for recurrent infections or unexplained weight loss. Rapid deterioration during illness, severe breathing difficulty, blue colouring, confusion or difficulty waking warrants calling 112. Do not wait for all signs or delay care by taking supplements.
