**Always remember to first check with your dietitian before incorporating new supplements into your regimen!**
1. ZINC
Zinc contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune systems. There is also evidence that it suppresses viral attachment and replication. Zinc deficiency is common, especially in those populations most at risk for severe COVID-19 infections, and is challenging to accurately diagnose with laboratory measures. Supplementation with zinc is supported by evidence that it both prevents viral infections and reduces their severity and duration. It has been shown to reduce the risk of lower respiratory infection, which may be of particular significance in the context of COVID-19.
2. ELDERBERRY
Elderberry is seen in many medicinal preparations and has widespread historical use as an anti-viral herb. Based on animal research, elderberry is likely most effective in the prevention of and early infection with respiratory viruses.
3. VITAMIN D
Activated vitamin D,1,25(OH) D, a steroid hormone, is an immune system modulator that reduces the expression of inflammation in the body and increases the elimination of diseased and damaged cells. Evidence suggests vitamin D supplementation may prevent upper respiratory infections. A laboratory range of >50 and < 80ng/mL serum 25-hydroxy vitamin D may help to mitigate morbidity from COVID-19 infection.
4. VITAMIN A
Vitamin A is a micronutrient that is crucial for maintaining vision, promoting growth and development, and protecting the epithelium and mucus integrity in the body. Vitamin A is known as an anti-inflammation vitamin because of its critical role in enhancing immune function. Vitamin A is involved in the development of the immune system and plays regulatory roles in cellular immune responses and humoral immune processes. Vitamin A has demonstrated a therapeutic effect in the treatment of various infectious diseases. and last but not least….
5. VITAMIN C
Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune systems. Supplementation with vitamin C appears to be able to both prevent and treat respiratory and systemic infections. Vitamin C has been used in hospital ICUs to treat COVID-19 infection.
