Allergy / Immune (Cold / Flu)

The Supplements against Cold / Flu

Colds and flu are viral diseases, which give similar symptoms, sometimes difficult to distinguish and classify. The infection is usually transmitted by droplet. With the onset of infection we tend to reach for home remedies such as onion syrup, plenty of garlic with milk,  lemon tea with ginger and honey. If they fail and the infection worsens, more radical medicines become necessary. One should remember that all natural preparations and specifics only support the treatment – they alleviate the symptoms, but should never replace a specialist visit. Changeable weather, excess stress, lack of sleep or other illnesses weaken the immune system giving perfect space for infection, so first of all it’s worth protecting and strengthening immunity, when the infection occurs, we can use supplement to aid the immune system in combating the microbes as well as support the treatment and relieve the symptoms, like fever, cough, sore throat, runny nose, otitis. It should be remembered that colds and flu are diseases that require us to rest to allow the body to fight an infection. Untreated infection can cause flu complications or lead to serious health complications and life-threatening ailments. What is effective for a cold or flu virus? In this category you will find various natural specifics in the form of pills, powder, liquid, syrup, ointments to bring you first aid in case of flu/cold, and to prevent their occurence.

  • The properties of Ascorbic Acid preventing Cold / Flu:
    Regular supplementation have shown that vitamin C reduces the duration of colds. Extra doses of vitamin C could benefit some patients who contract the common cold despite taking daily vitamin C supplements.
    • HEMILä, Harri; et al. Cochrane Database of Systematic Reviews, 2013, 1: CD000980. PMID:
      Conclusions: The failure of vitamin C supplementation to reduce the incidence of colds in the general population indicates that routine vitamin C supplementation is not justified, yet vitamin C may be useful for people exposed to brief periods of severe physical exercise. Regular supplementation trials have shown that vitamin C reduces the duration of colds, but this was not replicated in the few therapeutic trials that have been carried out. Nevertheless, given the consistent effect of vitamin C on the duration and severity of colds in the regular supplementation studies, and the low cost and safety, it may be worthwhile for common cold patients to test on an individual basis whether therapeutic vitamin C is beneficial for them. Further therapeutic RCTs are warranted.
    • SASAZUKI, Sasaki; et al. European journal of clinical nutrition, 2006, 60.1: 9. PMID:
      Conclusion: A randomized, controlled 5-year trial suggests that vitamin C supplementation significantly reduces the frequency of the common cold but had no apparent effect on the duration or severity of the common cold. However, considering several limitations due to protocol amendment, the findings should be interpreted with caution.
    • RAN, Li; et al. BioMed research international, 2018, 2018: 1837634. PMID:
      Conclusions: Extra doses of vitamin C could benefit some patients who contract the common cold despite taking daily vitamin C supplements.
  • The properties of Zinc preventing Cold / Flu:
    • MOSSAD, Sherif B.; et al. Annals of internal Medicine, 1996, 125.2: 81-88. PMID:
      Conclusion: Zinc gluconate in the form and dosage studied significantly reduced the duration of symptoms of the common cold. The mechanism of action of this substance in treating the common cold remains unknown. Individual patients must decide whether the possible beneficial effects of zinc gluconate on cold symptoms outweigh the possible adverse effects.
    • HEMILä, Harri. The open respiratory medicine journal, 2011, 5: 51. PMID:
      Conclusions: This study shows strong evidence that the zinc lozenge effect on common cold duration is heterogeneous so that benefit is observed with high doses of zinc but not with low doses. The effects of zinc lozenges should be further studied to determine the optimal lozenge compositions and treatment strategies.
    • HEMILä, Harri. JRSM open, 2017, 8.5: 2054270417694291. PMID:
      Conclusions: Properly composed zinc gluconate lozenges may be as effective as zinc acetate lozenges. There is no evidence that zinc doses over 100 mg/day might lead to greater efficacy in the treatment of the common cold. Common cold patients may be encouraged to try zinc lozenges for treating their colds. The optimal lozenge composition and dosage scheme need to be investigated further.
    • GARLAND, Michelle L.; HAGMEYER, Kathleen O. Annals of Pharmacotherapy, 1998, 32.1: 63-69. PMID:
      Conclusions: Treatment of the common cold with zinc gluconate lozenges, using adequate doses of elemental zinc, may be effective in reducing duration and severity of cold symptoms. The benefit appears to be maximal if the lozenges are started immediately after the onset of symptoms. The formulation of the lozenges also appears to be important because the addition of citric acid or tartaric acid may reduce efficacy due to chelation of zinc ion. Although zinc gluconate lozenges have dominated clinical trials thus far, further studies are needed to demonstrate the efficacy of zinc acetate lozenges and to determine whether their adverse effect profile is more favorable to that of zinc gluconate lozenges. Patients should play an important role in the decision-making process and must decide whether the benefit gained from treatment with zinc lozenges outweighs the potential adverse effects.
