How to Choose Immune Support
Immune health is supported by adequate nutrition, sleep, physical activity, and other daily habits. Supplements can help fill specific dietary gaps, but they do not replace a varied diet or prevent, diagnose, treat, or cure illness.
Check the amount per serving and avoid unintentionally doubling nutrients across multivitamins and single-ingredient products. Seek professional guidance if you have a health condition, take medication, are pregnant or nursing, or plan to use high-dose products.
