The Overview of available vitamin and supplement products used to improve immune system function

Abstract

Introduction: Questioning how we can boost our immunity during the infectious season often arises in the general practicioner’s office. Patients report issues with recurring infections, affecting not only children but also adults, particularly those in professionally exposed groups such as teachers. Therefore, is it worthwhile to recommend over-the-counter (OTC) products available in pharmacies to patients, aiming to strengthen their immunity? This article discusses the most commonly used supplements and immune-boosting preparations by patients and physicians, along with scientific evidence regarding their effectiveness. Material and methods: The basis of the work were medical articles collected in the PubMed database. The research was conducted by analyzing key words such as: vitamin D3, immunity improvement, zinc, bacterial lysates, lactoferrin, fish oil, omega-3 fatty acids, Echinacea purpurea, Spirulina maxima, curcumin, probiotics, ginseng. Results: In the pharmaceutical market, there are many supplements aimed at boosting the immune system. However, most of them lack sufficient scientific evidence regarding their effectiveness. The studies conducted so far are of low quality and limited in number. Further research is necessary to demonstrate the efficacy and safety of immune-boosting supplements.
