Nutritional Interventions for COVID-19: A Role for Carnosine?
As COVID-19 continues to take an enormous toll on global health, the effort to find effective preventive and treatment strategies has been unparalleled in recent history . While the rapid rollout of vaccines is heartening, limited supply, logistical hurdles, enormous demand, and the rise of new variants of the virus will make population-scale vaccination a challenging target to meet, particularly in lower socioeconomic areas of the world . This makes cheap, safe, and effective measures to limit the impact of COVID-19 of vital importance, and in this, nutritional interventions are particularly attractive as they are readily scalable. While some nutrients have garnered widespread attention for their potential use in preventing or managing COVID-19, such as vitamins B, C, and D [3,4], there are many others with powerful health-promoting effects that may have clinical utility. Carnosine is one such nutritional supplement, which could protect against some of the detrimental effects of SARS-CoV-2 infection.
