You cannot "boost" the immune system as most immunologists would agree that a too agressive immune system is dangerous. The advice is to try and maintain it and keep it healthy

The statement accurately reflects current scientific understanding of immune system function. Immunologists emphasize that the immune system is complex and requires balance: both an underactive and an overactive immune response can lead to health problems. An excessively aggressive immune system can cause autoimmune diseases or harmful inflammation, which is why the concept of 'boosting' the immune system indiscriminately is misleading.

Instead, experts recommend maintaining immune health through lifestyle factors such as proper nutrition, regular exercise, adequate sleep, stress management, and vaccination. These measures support the immune system's ability to respond appropriately without causing damage to the body. The idea of simply 'boosting' immunity with supplements or quick fixes is not supported by robust scientific evidence and can be potentially dangerous if it leads to immune dysregulation.
