The unexpected breakout of the new coronavirus has had a wide range of effects on many people's lives. People have not only overcome mild to severe symptoms but have also survived a variety of lethal and contagious forms. Furthermore, the long-term impacts of the SARs-CoV-2 virus have left many people depleted and fatigued. According to the specialists, after 12 weeks of infection, over 10% of COVID-19 patients were affected by extended COVID. According to their research, however, extended COVID may have psychological side effects in patients.

Loss of taste and smell are among the most prevalent symptoms of COVID-19, according to researchers studying the virus (except with the new Omicron variant). However, as more researchers look into the link, there are more hints as to why it occurs and how it might be treated. COVID-19-affected individuals suffered substantial physical and psychological impacts, including decreased willingness for eating, weight swings, low emotional well-being, and social bonding issues, according to medical researchers from the United Kingdom.

Although most patients' senses of taste and smell returned after a few weeks, about 10% developed persistent symptoms such as parosmia, which causes a person's familiar odours to be distorted. Smells that are ordinarily sweet or pleasant can smell rancid or terrible to people with parosmia. According to the authors of the study, people who experience persistent changes in taste or scent may believe they have an unseen sickness, which can lead to isolated ideas.

Some viable remedies have been proposed by a group of scientists from a famous Iranian institute, including vitamin supplements delivered through the nose. Researchers from Virginia Commonwealth University School of Medicine also discovered that those who had nasal congestion at the time of infection and were treated with Vitamin A supplement, were more likely to recover their sense of smell, whereas those who had trouble breathing or had previously suffered head trauma were less likely to do so.

In another trial, a group of nutritional experts led by an oncologist from Addenbrooke's Hospital in the United Kingdom developed a capsule that leverages the capabilities of natural substances to help patients with lengthy Covid recover faster. Purified citrus bioflavonoids, vitamin C sources or raw material itself, resveratrol, a plant ingredient that works as an antioxidant, pomegranate, chamomile, and turmeric are all included in the new capsules. According to the industry analysts, if trials involving vitamin administration to covid patients recovering from loss of taste and smell are effective, there is a good probability that global demand for vitamins will rise in the forthcoming period.
