Vitamins that help strengthen immune defence

Choosing vitamins with antioxidant power against free radicals to activate the immune system, contributes to maintaining health and well-being.

It is useful to maintain good health and know how to recognize the vitamins that help to strengthen your immunity. These vitamins help to enhance the immune system to fight possible infections such as colds and flu when you have low immunity.

The human body has a complex and effective defense mechanism that allows it to stay healthy despite exposure to different conditions such as climate change, natural environments, contact with its own and foreign micro-organisms.

Therefore, it is essential to help this multifunctional system to stay healthy with an adequate diet that provides nutrients, vitamins and minerals, as well as macro and micro-elements that help strengthen your immunity.

These are required as millions of enzymatic reactions take place within the human body that contribute to fight against free radicals formed habitually or due to a particular situation associated with lifestyle, unhealthy habits or the presence of germs that intend to damage our tissues.

Choosing vitamins with antioxidant power against free radicals, in order to activate the immune system according to the needs of the body, contributes to maintaining health and well-being.

Vitamins that help improve your immune system

Vitamin C has been used for years to help strengthen our body’s immune system to fight illness including colds and flus. It is a powerful antioxidant that contributes to protecting our cells against micro-organisms entering and causing damage.

It also favours the nutrition of the muscles avoiding the appearance of the symptoms and discomforts associated with fatigue and muscle weakness. In addition, vitamin D is a powerful modulator of the immune system and fundamental in the activation of immune defence.

Zinc is a mineral we need to support many functions of our body. Zinc helps to support the skin's physical barrier, protect cells and tissues, support a general immune response and help produce antibodies. Zinc deficiencies may lead to more frequent bacterial and viral infections.1

Maintaining a healthy immune system

Nature provides us with a diverse range of micronutrients from fruits and vegetables which should form part of a healthy and balanced diet, to help maintain a healthy immune system.

However, if you suspect you’re not obtaining adequate amounts of micronutrients through your diet, then taking vitamin supplements can help to support your immunity. Taking vitamin C, D and Zinc supplements that help to strengthen your immune system along with a healthy balanced diet, can allow the body to defend itself and work effectively to keep you healthy.
