Cold Sore Supplements

Cold Sores are caused by an enveloped virus called Herpes Simplex Type 1. Around 90% of people have become infected with this virus, which persists for life. Because it is an enveloped virus, it is also termed an opportunistic infection, meaning that when the immune system becomes suppressed—which may occur during another infection, such as the common cold—the enveloped virus becomes active.

It therefore makes sense that those who suffer with compromised immune systems are more prone to cold sores. And guess what? One of the factors that increases cortisol secretions and suppresses general immunity is psychological stress. Other factors that contribute are excessive sunlight exposure, poor diet, lack of exercise and irregular sleeping patterns. High dietary arginine levels have also been linked to cold sore recurrence. High dietary sources of arginine include: pumpkin seeds, peanuts, turkey, pork and soyabeans. Omiting these foods from the diet until the infection is under control is a good idea. 

Some of the most helpful supplements supplements that support the body during cold sore infection are those that support the immune system, and those that directly have an anti-viral effect. Interestingly, some of the most powerful natural anti-viral compounds are the minerals zinc and iodine. Additionally, the amino acid lysine directly slows replication of the Herpes Simplex Type 1 virus. These compounds simply help to suppress viral replication, which allows your immune system more time to get the infection under control. This is actually similar to how a fever works. Other nutrients that support general immune function are selenium and vitamin C, and herbal medicines, such as echinacea and andrographis.
