Immune Health

Immune Health and Nutrition

The immune system works best when it's well supported day to day — through sleep, movement, sunlight and diet. This area of our blog covers that everyday picture in full. The immune system is always active and how well it's resourced depends heavily on the basics: consistent sleep, regular movement, time outdoors, key supplements such as vitamin D and a varied, nutrient-dense diet. Here's what actually supports immune function, which nutrients matter through the year and what the evidence says.

Common Questions

  • What's the best food for immune health?

    An anti-inflammatory diet rich in fruits and veggies, proteins, healthy fats and carbohydrates is a good place to start. Limit alcohol, processed foods and focus on immune supportive nutrients such as vitamins C, D and zinc. 

  • Does vitamin C actually prevent colds?

    Vitamin C contributes to several aspects of the immune response, including supporting the function of immune cells and providing antioxidant protection against oxidative stress.
