Herpes simplex virus, often abbreviated HSV, is very common and comes in two main types: HSV-1 and HSV-2. HSV-1 most often causes cold sores around the mouth and on the lips, while HSV-2 is more often associated with genital herpes. The virus remains dormant in nerve cells and can reactivate during periods when the body is under strain from, for example, stress, illness, menstruation, or strong sun. Learn about symptoms, transmission, and what can help reduce outbreaks.
Colds are common, especially in autumn and winter, when many people spend more time indoors and are exposed to various viruses. There is no single product that can guarantee you won’t get sick, but sleep, a nutrient-dense diet, recovery, physical activity and adequate fluid intake are important parts of the body’s normal resilience. Some vitamins and minerals also have EU-authorized health claims related to the normal function of the immune system. Other substances are interesting from a general nutrition or antioxidant perspective, but should not be described as preventing, treating or curing colds.
Lipopolysaccharides (LPS) are fat molecules found on the outer cell membranes of bacteria. They can cause significant damage, but quercetin appears to offer protection.
