The health expert community is still arguing about the feasibility and usefulness of taking supplements and vitamin complexes. The nutraceutical and pharmacological companies produce these preparations in large quantities. However, the bottom line is that you need to choose the best ones containing the essential vitamins A, B, C and D.

When it becomes necessary to supplement the main diet with alternative sources of nutrients, or if emergency assistance is needed to strengthen immunity for a more effective fight against colds, flu, and other respiratory viruses you should turn to natural supplements.

Vitamin D and Zinc Proven to Boost Your Immunity

Scientific studies have shown that foods containing vitamin D and zinc can help strengthen the immune system and avoid respiratory infections.

Taking vitamin D supplements can help reduce the risk of respiratory infections, including the common cold, flu, and pneumonia. This applies primarily to those who do not receive the required amount of this vitamin from a daily diet or due to a lack of sunlight.

Zinc can help reduce the duration and severity of cold symptoms if taken orally with a direct effect on the throat. For example, swallow or chew a zinc supplement Immune Defense in the form of a lozenge that can kill viruses.

Taking either of these two supplements can help prevent or reduce colds. Here is the source for more details.

Immunity Support Supplements Benefits

Most often, the composition of biologically active additives includes substances of plant nature, and components of animal origin are used much less frequently. Most often, the ingredients of immunity supplements are obtained by processing the roots, seeds, shoots, foliage of various medicinal plants.Try Immune Defence - Immune System Support

To increase the effectiveness of additives, micronutrients, probiotics, and other useful substances are often introduced into their composition. The positive properties of dietary supplements for immunity can be reduced to three factors:

  • micronutrient deficiency is eliminated;
  • harmless cleaning is carried out, which leads to the disposal of toxins from the body;
  • Enzymatic protection at the level of cellular structures is enhanced, and nonspecific immunity is also enhanced.

Particular attention should be paid to the last point since it is he who contributes to the maximum strengthening of the immune system. Basically, dietary supplements for immunity actively affect the digestive system, while enhancing the entero-and gastroprotective function of the mucous membrane and normalizing the composition of microflora.

Try zinc lozenges Immune Defense with vitamin C rosehip and acerola. These soothing anise-flavored lozenges dissolve quickly in the mouth and act right in the throat, supporting antiviral protection for colds and flu.


It should be remembered that many proven vitamin preparations will really help to fill the lack of nutrients and vitamins. But do not forget that the main and best source of vitamins, minerals, and other beneficial substances is a properly balanced diet.

Most dietary supplements can theoretically be taken by people of any age and gender for the prevention of colds, as well as for immunodeficiency and autoimmune conditions. But each organism has its own individual characteristics, so always consult your doctor before taking any supplements in order to eliminate the occurrence of side effects.

Taking a variety of quality supplements and vitamins have a number of health benefits and can help ensure the normal functioning of the immune system, especially during the cold seasons during outbreaks of viral infections. And learn to be less nervous because stress greatly reduces immunity.

It is important to understand that dietary supplements are not intended to treat viral or other inflammatory diseases like coronavirus. They can be used only to supplement the diet in order to enhance the protective properties of the body.
