Nutrition and you
Boost Your Immunity With Antioxidants
Key Nutrients To Help Support Healthy Immunity
Good nutrition is essential for supporting a strong immune system in several ways – the following nutrients are key:
- Protein - for the building of antibodies and immune system cells.
- Vitamin A - helps regulate the immune system and protect the body against infections by keeping skin and tissues in the mouth, stomach, intestines and respiratory system healthy.
- Vitamin C - helps the body build healthy skin and connective tissue, which helps to block the entry of foreign microbes.
- Vitamin E – a powerful antioxidant, protecting cell membranes from damage due to free radicals. Healthy cell membranes help keep foreign microbes out.
- Vitamin D - helps to activate immune cells and properly regulate their function.
- Zinc – necessary for wound healing and for cellular reproduction, which is important in the synthesis of new immune system cells.
- Antioxidants – such as vitamin C, vitamin E, and selenium – help prevent oxidative damage to cells during the immune response to invading pathogens and during infection
- Other nutrients, including vitamin B6, folate, selenium, iron, as well as prebiotics, probiotics, may also promote proper immune responses.
How Ensure Can Help
- Ensure is a scientifically designed, oral nutrition supplement , for adults that has been available for more than 45 years and studied in over 5,500 individuals in 30+ clinical studies.
- Ensure products are a source of complete, balanced nutrition with essential macronutrients and micronutrients to support overall health. They can be consumed as a health shake, or used as an ingredient to fortify many of your favourite recipes.
- Ensure serves as a source of supplemental nutrition in times when people cannot consume enough nutrition from food, or for those who simply want to boost their immunity or to aid in recovery from illness.
- Ensure products are a source of key nutrients, such as protein, vitamin A, zinc, antioxidants, that play important roles in immune health.
- Antioxidants are essential for immune function.
There are simple lifestyle choices we can make to help keep our immunity at its best. A nutritious, balanced diet, regular exercise, and generally all the things that improve our gut health and heart health.
The relationship between nutrition, infection and immunity is well known. One component of a nutritious diet that is particularly important to a strong immune system is antioxidants.2 Antioxidants are our body’s first line of defense against free radicals – unstable molecules that can damage body cells.2
Common antioxidants found in the diet include vitamin E, vitamin C, selenium, copper, iron and zinc. Each of these antioxidants improve different immune functions and so have an important role in improving our defense against disease.2
