immune system

Optimal nutrition is the cornerstone of preventative health, a concept built on the ethos that prevention is better than cure.

A preventative approach focuses on keeping you healthy, rather than treating an illness when it takes hold. In the context of seasonal sniffles, this means taking steps to boost your immune system – your body’s natural defence against germs. 

Food fuels your immune system

While not a guarantee against getting sick, with the winter cold and flu season looming, now is the time to support our immune systems with optimal nutrition built on a solid foundation of a wholesome nutrient-dense diet and a comprehensive supplement plan for added support. 

A nutrient-dense diet that consists predominantly of natural foods provides a range of beneficial substances such as phytonutrients, vitamins, minerals, fatty acids, fibre and antioxidants, which our body requires to produce immune cells and support other important immune system functions.

Up the nutritional ante

While a healthful and wholesome diet should provide most of these nutrients, we can sometimes experience shortfalls or deficiencies, or may require extra vitamins and minerals beyond levels that our diet can adequately provide, especially as nutritional demands can rise when our body is fighting off an infection. 

Thankfully, supplement manufacturers have taken the complexity out of immune support. Comprehensive complexes that combine various vitamins and minerals proven to support immune system health and function offer a convenient and effective means to meet your nutritional demands, especially during cold and flu season. 

For example, Biogen’s Immuno Boost Effervescent with Extra Strength Vitamin C (1000 mg) contains various ingredients that can strengthen and support the immune system.

Biogen Immuno Boost Effervescent

Biogen Immuno Boost Effervescent is formulated with echinacea to boost immunity and vitamin C, B-vitamins and zinc to provide additional essential nutrients needed to maintain good health and contribute to normal immune system function.

These ingredients support a strong immune system in the following ways:

This natural ingredient boosts white blood cell production, which can help the body fight off bacterial and viral infections. A 2014 meta-analysis¹ also found that this popular herbal remedy showed a benefit in preventing colds.

Immune cells require vitamin C to protect them from free radical damage. Certain immune cells also require vitamin C to function optimally. As such, this vitamin is highly concentrated in immune cells and is consumed quickly during an infection but the body cannot synthesise vitamin C, which means we need to get sufficient amounts from food and supplements. Studies² show that vitamin C can also reduce the severity and duration of colds.

Zinc functions as a co-factor for important enzymatic reactions involved in the antioxidant defence system, making it essential for a healthy immune response. Studies³ link zinc deficiency with a decline in lymphocyte function, which compromises immunity.

The body requires sufficient amounts of various B vitamins to produce cells involved in the immune response.

  • Vitamins B6 and B12 aid optimal immunity because they are involved in numerous internal biochemical reactions related to optimal immune function.
  • Similarly, vitamin B2 (riboflavin) helps produce antibodies, and is essential for energy production and antioxidant activity.
  • Vitamin B5 (pantothenic acid) is converted into coenzyme A, which is essential for many cellular processes, including the production of antibodies and inflammatory cytokines. Studies⁴ also suggest that vitamin B5 may play a role in stimulating the activity of immune cells like macrophages, and might contribute to maintaining the health of mucous membranes, which act as a physical barrier against viruses and bacteria entering the body.
  • Vitamin B3 (nicotinamide) helps to activate the innate immune system, potentially increasing its effectiveness against pathogens while supporting white blood cell (phagocyte) activity to help destroy bacteria and other harmful particles.
A holistic winter wellness approach

While a nutritious diet that support sufficient nutrients is a cornerstone of winter wellness, a holistic approach is key. Additional preventative measures you should take include:

  • Prioritise sleep: Aim for 7-8 hours of quality sleep each night to support immune system repair and function.
  • Manage stress: Chronic stress can weaken your immune system. Consider relaxation techniques like yoga or meditation.
  • Wash your hands frequently: This simple act is one of the best ways to prevent the spread of germs.
  • Exercise: Regular exercise improves health and supports your immune system by creating greater resilience.
  • Stay hydrated: Drinking sufficient water keeps your mucous membranes moist, which can act as a barrier against viruses.

Taking steps now to fortify your body will give you the best chance to sidestep those sniffles and stay healthy through winter. 

So stock up on colourful fruits and veggies, prioritise rest, get some exercise and wash those hands! You can also download the FREE Biogen Immunity Toolkit for additional tips, guidelines and helpful information to make winter wellness part of your daily routine.
