Immunity Support

Dietary intake of essential nutrients will promote your immune response. Zeapure supports your immune health alongside a balanced whole food diet.

Viral infections are a global public health concern, as highlighted by annual influenza episodes and the current Covid-19 outbreak. Certain vulnerable population groups, such as elderly people and young children, can be at higher risk.

Recommendations for management of viral infections include standard public health practices (e.g. hand washing, distancing, vaccinations if available) that help reduce the spread of respiratory tract infections, as well as reliance on the body’s immune response.

Against this background, in February 2020 a panel of global experts in nutrition reviewed the role of micronutrients and omega-3 fatty acids in their support of an effective immune system*.

Their conclusions:

  • Essential nutrients work together to support a healthy immune system. These nutrients include vitamins A, B6, B12, C, D, E, and folate; trace elements such as zinc, iron, selenium and magnesium; as well as the omega-3 fatty acids EPA and DHA.
  • • Adequate nutrient intake is important for a healthy immune system. For some micronutrients, intake above the nutrient requirements may better support optimal immune function.
  • • Nutrient intake should ideally come from a well-balanced diet, but this is often difficult to accomplish. Indeed, nutrient shortfalls are common in many countries.
  • • Nutritional supplements offer a safe option to complement the diet, eliminate potential nutrient shortfalls and help support the immune system. Micronutrient intake levels should fall within recommended safety limits set by health authorities.
(*The objective of the panel was to independently review the scientific evidence regarding the roles micronutrients play in support of the immune response, including against viral infections. The panel was hosted by Prof. Dr. Manfred Eggersdorfer (UMC Groningen, The Netherlands) and facilitated by DSM on 6 Feb 2020. Attending experts included Prof. Anitra Carr (University of Otago, Christchurch, New Zealand), Prof. Jens Lykkesfeldt (University of Copenhagen, Denmark), Prof. Adrian Gombart (Linus Pauling Institute, Oregon, USA) and Prof. Philip Calder (University of Southampton, UK))

Vitamin C and respiratory tract infections

Studies have shown that vitamin C appears to exert a multitude of beneficial effects on cellular functions of both the innate and adaptive immune system. It seems to be able to both prevent and treat respiratory and systemic infections by enhancing various immune cell functions. Taking at least 200 mg of vitamin C per day appears to reduce the duration of cold symptoms by an average of 8% in adults and 14% in children, which translates to about one less day of illness. Note that at doses above 400 mg, vitamin C is excreted in the urine.

Vitamin D and upper respiratory tract infections

Vitamin D can modulate the innate and adaptive immune responses. Deficiency in vitamin D is associated with increased autoimmunity as well as an increased susceptibility to infection. Daily vitamin D supplementation raises the blood serum levels and as such lowers the risk of acute respiratory tract infections.

Zinc has important properties relevant to the immune system

Zinc deficiency affects immune cells, resulting in altered immune defense and increased risk of inflammation. The antioxidant properties of zinc help to protect immune cells. It further helps to promote the growth, maturation and activity of both innate and adaptive immune cells; and is involved in the function of several hundred enzymes. Zinc is also reported to be important to support phagocytosis (eating the pathogen), antibody production, proliferation of activated T cells, and cytokine release.

Omega-3s are essential for optimal immune function

The omega-3 fatty acids EPA and DHA help resolve inflammation, and support healing after an infection. Benefits of omega-3s have also been observed in individuals suffering from asthma and allergic respiratory diseases. In general, typical dietary intake and status of omega-3 EPA and DHA is insufficient. Your body can’t produce adequate amounts of omega-3 EPA and DHA, so it’s important to get them through the diet and by supplementation in optimal amounts.
