A healthy immune system is needed to fight infection, prevent disease, and maintain
overall well-being. Lifestyle factors like diet, exercise and stress levels affect immune
function. The use of immune supplements has increased significantly in the last few
years, particularly since the start of the COVID-19 pandemic. Dietary supplements
are not meant to treat, cure, or prevent diseases; but can add to or ‘supplement’ a
healthy diet. Immune supplements contain a variety of ingredients, ranging from
vitamins and minerals to herbs and spices. When used in the correct circumstances,
immune-supporting supplements are beneficial for health and immunity. It is
important for the front shop worker to understand the role of supplements in health
and immunity.
Front shop workers should familiarise themselves with the most common ingredients
found in immune supplements, how they function within the body and which
population groups may benefit from supplementation.
