The Hype of Immune Boosting

During the pandemic, there has been a surge of interest in immune-boosting supplements and products. Social media platforms have been flooded with influencers promoting various immune-boosting products, ranging from vitamins and superfoods to herbs and smoothies. However, the question remains: do these products actually work? While some studies show that certain supplements like vitamin C can potentially shorten the duration and severity of cold symptoms, the overall evidence is not definitive. Similarly, herbs like elderberry and echinacea have shown promise in lab studies but lack consistent results in human trials. It is important to note that many of these products are not FDA-approved, and companies often make unverified claims. Therefore, it is advisable to approach immune-boosting products with caution and focus instead on proven strategies like exercise, good sleep, and vaccination as effective means to support the immune system.
